RC8 top speed 100 mph

[@MikePeperni]

My friend sold that buggy a little after the test.... but he ordered the pinions, a 28t 30t and 32t... too bad he sold the buggy im sure we could have hit a LOT more :) good luck with your setup! the 2650kv in the buggy is insane and sound very nice:)

[@MikePeperni]

@timburrtremor They are ofna foam, they are pre-glued, for 1/8 scale. :)

[@MikePeperni]

@cigaretteone03 no problems using the rc8e mount. :)

[@MikePeperni]

Nice :) For the 100mph run , it was fairly easy with the setup we had, we just needed a wider gearing. Unfortunatly my friend sold the buggy too early... we will test his DM1 next summer, we got 101mph last summer with it not on video, right before a crash due to a bearing problem... The ofna foam seemed to hold up pretty well to any 100mph runs we did. Good luck :)

[@MikePeperni]

Thx vcsss :) My friend was driving the buggy, he said it was pretty easy to drive, it is well setup.

[@emptyqrider]

another amazing project Mike :) Congrats bud and wish more success in near future man. Note: honestly still thinking why didn't any RC company hired you yet ?

[@MikePeperni]

@350zvj doesnt matter , the speed update on the radar a few times per second, it doesnt take into account previous number, and it will show slower while i turn around anyway because the angle at the radar is pointed at is higher than aimed directly, it wil show the most accurate speed when you aim direct at the object, other than that it will show lower, only way id see to increase the speed showed is to run toward the incoming RC... never tried though. It show the same if im standing still

[@rebelyell22]

@Tunknatar haha the mini e-revo VXL comes with a VXL system

[@Leon-Servant-of-Christ]

I guess we are still on for the end of august/ begining of september, so make sure your RC8te is ready for some speed runs !!(plus some awesome bashing afterwards !! I can't wait !!!)

[@MikePeperni]

@costanzo5137 Hi, it was a single 6S battery, to change the spur gear you need to remove the center diff and replace the spur gear. Not difficult. But we ran a custom center shaft to run a smaller spur gear than you cant find from team associated. :)

[@MikePeperni]

@MikePeperni It doesnt matter when i turn around, when i aim the radar to the RC at the end im not moving the radar update the speed and will not take into accountthe previous number if it was slower, and it always show slower as im turnin around, since the angle at wich im pointing the radar to the RC is wider... i have videos that show the radar vs GPS.

[@MikePeperni]

@studdgage Thx, but theres no clutch. It was the motor cogging due to the very wide gearing. :)

[@MikePeperni]

@VisionaryStyles thank you :) It was a custom solid center diff, no oil, full time awd. :)

[@MikePeperni]

No problem, it ran flawlessly on 6S :) The sound on 6S is amazing too!

[@ibefilmin]

Yeah, I saw that at the end too. There is even a shot of it going around 97mph before moving so you're close enough, moving it wouldn't throw it off by that much. Nice jobs Guy. The owner of Caster Racing saw the video and is trying to do it with a Caster. Hit them up, I bet you can get a discount on the kit if your going for top speed with it.

[@MikePeperni]

@costanzo5137 We ran 25t 34t. the 34t is an integy spur gear for the traxxas nitro revo. We modified an ofna solid shaft to add a revo slipper plate, that will hold the spur gear. My friend di that mod so i dont know for sure the exact procedure. But thats what he did. Hope that helped, :)

[@MikePeperni]

@1967CamaroSSRSYenko you can strap both baterries one over another, you may need longer strap... You may also need to play with the pinion to get desired speed and make sure it doesnt overheat... 6S will go 2 times faster than on 3S. oh and i did an error, connect both in SERIE to have 6S, or run two 3S in parrallel to have longer runtime (10000mah instead of 5000mah for example...) :)

[@MikePeperni]

@WarhawkLegend69 thx man :) just use the zip-ties to tie both rocker together, just route the zip-ties under the rockers and tie it on top, the rockers are the grey parts that look like a triangle... that moves when you apply pressure on the truck and see the suspension travel... Hope that help, :)

[@MaciekPL87]

that's amazing, you must have a top of the line controls for this beast, wouldn't want to run that into my foot at that speed.

[@MikePeperni]

Thx! :) Geared that way i have no idea, on a bashing setup its about 30 minutes. Id say 10-15 minutes geared for 100 mph. we never ran long enought during a speed test to hit the battery low voltage cut-off.

[@MikePeperni]

@1521joe No problem :) We tried the RC8Te (still working on it..) we did a baseline test on 25t 50t with the 2200 MMM on 6S, we got 75mph over reving. I highly suggest to switch to a solid center shaft (eliminate center diff...) :)

[@MikePeperni]

@Jeenyus1983 thx man :) they can have problem starting the engine for break-in its normal, try heating up the engine before starting it with a heatgun, at least to 150F, and slightly loosen the glow plug, as soon as it start retight the glow plug . :)

[@rebelyell22]

@Tunknatar wrong its got a tembol mount with a mamba system and lots of other stuff

[@MikePeperni]

@midnightRCcrew thank you! :) 105 mph is very nice, we have done similar speed with my friend's DM1 (still in progress) at about a little over mid throttle on a Neu 1515 1.5d, we need to find a nicer road, it just jump over bumps at those speed... i had a video of it hitting 101mph in a very short distance and then flying and crashing into my friend's 1:1 car... lol bending the chassis... never posted it i though we would have redone new test since, but never happened... should this summer.

[@MikePeperni]

@C00lman555 The Phaltlines tires are bigger, i think team associated made the best rubber tires buggy size, if the road is dusty, the foam wont do good, you need a clean road, if you crash the foam will get damaged more easily, it depend on a lot of factor, but they handled 100mph no problem, i head those rubber handle about 105... the ofna rubber dont last over 65 for a long time. I used the medium compound i think, it doesnt matter, but the harder one will last longer...

[@MikePeperni]

@RemotedEntertainment it is less stable without the wing, it make a huge difference in the way the buggy handle. :)

[@MikePeperni]

@2bigtit thank you for your comment :) or the radar, we have every way and it doesnt matter it always shown the same, turning around make no difference, it will show lower speed if youkkeep your finger on the radar while turning though, but from one siode or another we got very similar speed, the main reason to radar ''away'' is to make sure the cameraman is not hit by the car at full speed. :)

[@MikePeperni]

Yeah the driveshaft were poping out as well,i cant post link , but search for ''ofna solid center drive'' on google, tahts what we used, and we used also the traxxas revo slipper/pressure plate, it come as a kit with the slipper and the spur gear mount, we used the spur gear mount, you will have to use your imagination from there i dont remember everything and its hard to describe... its easy to build. to use ofna dogbones (driveshaft) you will need new drivecup though..

[@MikePeperni]

@EyeSquaredAre no gyro, it was going straight as an arrow, we used an ofna rear wing the stock one had too much downforce. No vibration that are abnormal :)

[@MikePeperni]

The price of the buggy (factory team version) + the conversion + tires+ lipo+pinion+MMM 2650kv combo+ modified spur gear. somewhere around 1000$.

[@MikePeperni]

@BritishRaver we used a metal spur gear , 34t

[@MikePeperni]

@jaroncyr lol so how moving it following the car would increase speed if im following it? i tested and tested so many times, we even showed with the GPS and it is withing 1 mph range, also shown gps vs car vs radar, all the same mph. The radar will update the speed every half econd or so, and im steady with the gun when it is still accelerating, the last speed shown was the fastest.... it dont take care of any movement unless it show faster while im moving around.

[@MikePeperni]

@2bigtit Thx man :) i agree a box to hold teh radar gun would be best, we also used a GPS strapped on the cars, worked great, and was within 1mph of the radar most of time :)

[@MikePeperni]

@02SilverWS6 turnigy is fine :) if you use a 25t pinion only with ofna foam tires and your 6S you will get 75mph with the 2650kv motor. :)

[@MikePeperni]

no unfortunatly, the wheel help keeping it planted on th ground, otherwise its uncontrollable, we did cut the wing to have the right amount, we used a ofna wing, the stock one had too much downforce.

[@Leon-Servant-of-Christ]

Well Mike, it's going pretty well ! I got it upto almost 120Mph (115Mph to be exact) but my foams keep self destructing lol (I went threw 4 sets in 6 runs!!) after 115Mph the foams let loose from their wheels and fly off(I even tried super gluing the sides to help remedy this) So thats the scoop so far. Novak is sending me a super 6 Cap. Trans Cap wired to an H.V. ESC and gave me some tips on cooling their motor, so it's coming along ! I should have the video up by june sometime !

[@MikePeperni]

thats the one we ordered, but never could try them, my friend sold his buggy a day after he ordered the gears... i cant say if they will hold up. i will ind out this summer :)

[@MikePeperni]

They are made by ofna, you can get them at nitrohouse wich is the main distributor.

[@MikePeperni]

@VisionaryStyles No, nothing was cut. It was just right for the buggy like that, less downforce than the stock one. :)

[@MikePeperni]

@JKZD In a buggy the 2650 is very nice, torque is similar in the buggy, but in a monster truck or a truggy the 2200 handle more amp before overheating. I prefer the 2650 in a buggy. running 5S or 6S even if its not rated to run those cell.

[@jlr6]

The only thing bad about my rc8 is the rear differential,i keep stripping the gear around the dif housing.

[@MikePeperni]

@1521joe WHen i said over reving, i said it topped out to its max rpm on 6S, we dont really bother if it spin faster hehe we ran the 2650kv on 6S even if they recommend 4S and it ran flawlessly. We will switch to 25t 34t soon, you need to do custom shaft for solid center diff.

[@heffernjustinheffy]

love the metallica at the beginning and dam fast car

[@midnightRCcrew]

hey mike! great vids! i like the dm1 with O.S. 28 too! i almost had adam make me an engine, but i decided to go brushless for now. hehe if u have time i wanna share with u my vids :) my DM1 is currently consistent at 105MPH on mamba 2650kv on the radar gun. Im from California. I know u have faster cars than mine, but just wanna share and get a comment from one of the most respected RC experts on youtube! :) Thanks sir!

[@MikePeperni]

@CygnusX250 Thx man :) yeah i really enjoy speed runs, lots of fun :) We tried without the wing, and it was uncontrollable, we changed teh stock RC8 wing to an ofna wing and it was trimmed for the best downforce, it was not struggling at 100mph, it was over reving, we were waiting for teh new gearing, unfortunatly my friend sold his buggy before even receiving the gears... lol he is a compulsive buyer/seller :)

[@Leon-Servant-of-Christ]

I have been talking to maxxamps for some different battery configurations and so on and they reccomended me to run a 5S LiFe (16.5v) 5000 60C pack, and I'll be running the Novak 5000kv 4.5T H.V. motor gears arent that big of a secret but you'll just have to wait n see this spring !! But Hopefull we are looking at 120+ depending on the tires holding up !

[@MikePeperni]

@JAMESTAPPJR I simply connected the battery and go. If you overload the motor yes it may dont last. It never failed, we ran the buggy a lot on 5S bashing in sandpit as well. :)

[@MikePeperni]

We also used the 2650kv for bashing, we ran it on 5S. For 3S you could use a 21t, with the bowtie tires we got 47mph and still enought power to pop wheelies. For 4S i would use a 19t pinion that should get you a little over 50mph, but with more brutal acceleration. :)

[@MikePeperni]

Thx :) I got the same results, it was always the same or 1mph +- difference. I have plenty of videos where we hit 77-78 mph with the mini that way and the GPS show the same.

[@MikePeperni]

@C00lman555 8000mah's 3S are big, if you find a way to fit them its okay in serie, the 2650kv is really nice it sound good on 5S or 6S. Id still use 5 or 6S no problem as soon as the gearing is right :)

[@MikePeperni]

@Jason5291984 It was a 34t spur gear :)

[@MikePeperni]

Not too sure, been a while, i think it was a 21t

[@MikePeperni]

@MrMRTmustang1 We modified Ofna ones to fit, we modified drives cup if i remember. :)

[@jose887000]

wow mike amaizing speed!!!!!!!!!! you are the man nice vid

[@MrMRTmustang1]

what front and rear center drive shafts are you useing . i keep brakeing the the joints in them

[@Leon-Servant-of-Christ]

now that was a decent video !!! Good job guys !!

[@ABPalacios]

the 2650k isnt rated for 6s..but i see ppl do it....would be ok, if i get that motor and always use 6s? or would it do internal damage to it?

[@MikePeperni]

@1521joe I would not suggest to run such gearing ion regular basis, just the 25t its not too bad, for 75mph, but geared for 100mph you can hear a lot of cogging on start until the buggy move, with just a 25t pinion it was not too bad, still driveable. For acceleration, there was well enought power at any gearing, its just what your esc can handle and what the battery can give, geared at 100mph it was as strong as geared for 75mph, but the system was pulling more amp= more heat.

[@2bigtit]

I know what you mean, we had that same problem at first then one of the guys built a speed box to hold the gun.. Your RUN was SUPER FAST...

[@draven3907]

114mph that's fast nice. i did 103 but i was at half thorttle and no timeing on the motor. i will tune the motor this weekend and send you the vid if i do good

[@TheTaternator2]

Thats fast, alot of money and time too! Great buggy!

[@MikePeperni]

With the 2200kv you can use 6S no problem, first of all you need to make sure the lipo you get fit into the battery compartment, in a buggy even 3S will have more torque than nitro so you will be happy, id use 2 3S connected in parrallel, so you can run 3S or 6S to your liking, 4S or 5S would also be good but you need a lot of different batteries... you can get two 3S lipo at least 30C discharge rate, and 4200mah, we used Thunder power 4200mah 40C and 5000mah, and also SMC 30C 5000mah

[@aqwut]

Great Job man... awesome!

[@mrhappypie32]

I have the rc8.2 with same setup and it does 100mph and I love it :)

[@MikePeperni]

@Bmw325isTT We could get very hard acceleration, but it would be hard to control, on my friend's DM1 it was brutal, for the buggy it was great, we just needed more gearing, we ran 24t 38t mod1 I see no problem if you want to clock your setup this next summer :)

[@MikePeperni]

And most of the time i release my finger from the trigger while turning around.. I tested without moving and while moving and its the same. As soon as you are aiming at it correctly in line when it reach its maximum speed your ok.

[@MikePeperni]

@Tunknatar Where did you get you had to clock it going toward you? lol radar can be used to go both ways.

[@MikePeperni]

No problem :) front/rear was 7k i think, center locked.

[@vcsss]

100mph, thats insane dude!!! That's pretty good driving too at those sort of speeds. Do you turn the steering down on the radio for your speed runs?

[@WarhawkLegend69]

hey bro you have some very amazing videos bro, i have question i see that for the e-revo for lowering ittt you were saying you were useing zip ties curious were you puting that between the arm and the body mounts ? just got my hpi phaltline and tremor wheels they are chromed version and look SOOOOOOOOO amazing on my e-revo just wanting it a bit lowered THANKS BRO

[@scrivtwin2]

@MikePeperni do you use the "Oversized Acetyl Pinions with Brass Reinforcement" seems those are the only ones that are those sizes. if so i guess i dont have to worry about strength?

[@Leon-Servant-of-Christ]

Pro-line just came out with them mike, but I don't think they are in stock yet, also try aka racing !

[@MikePeperni]

It was a 34T spur gear :)

[@MikePeperni]

We used the team associated conversion, and also used a Castle Creation Mamba monster max controller with a 2650kv motor (the 2650kv combo..) :)

[@MikePeperni]

Its a castle creation 2650kv motor , brushless. :) Thx!

[@Jeenyus1983]

just subbed-AWESOME channel! just got my rc8b done with a sts pro .28 thats fully modded-bought the new 80.00 losi box with twin 550's and the damn thing barely had enough pull with no glow plug,break in oil,everything lined up etc... what do you know about the ofna truggy box? twin 750s

[@ben150785]

God damnit! I had my heart set on a Vorza, now im not sure whether to get one of these instead!

[@petervelker1990]

do you know what the part number was for the ofna foam tires you used in the video.

[@Tunknatar]

@backintack umm yea wat dat gotta do wit anything??

[@DeltaKT]

nice! metallica in the background!

[@MikePeperni]

@Unreal3man ofna foam tires. :)

[@MikePeperni]

And if you really think about what you say, to make it go faster i would need to move it backward, if i was moving forward it would reduce my speed theoricaly. The speed is updated several times per second, you can see on the finals reading im steading on not moving anyway.

[@MikePeperni]

@RCjunky1 thank you! :)

[@thomasbrummg]

When I buy this custom center diff?

[@scrivtwin2]

@MikePeperni duh lol i forgot he never got to try it. mod 1 seems pretty tough in general so maybe ill give them a shot

[@MikePeperni]

@TRAELEVATION You need a wider gearing, (bigger pinion or smaller spur gear) and foam tires. and work on its handling, if the front end want to lift you need to remove a little rear downforce... hope that helped, :)

[@ibefilmin]

Cool man! Good to know it's been double checked. We were dicussing it with radar techs on another forum. Check out the Consine effect.. It's states the error in the reading from a moving gun... Run it again leave the gun stationary, prove me wrong. :D :D. Just razzin ya, thanks for the reply.

[@MikePeperni]

the smallest we used that fit the stock center diff got us 75mph on 6S, cant remember the tooths, in this video we made asolid center shaft with a 34t revo spur gear.

[@scrivtwin2]

hey hows it going. do you know where i can by the 28-32t pinions? i can only find up to 26t. unfortunately unless i change my diff im pretty sure my buggy only has a 51t spur

[@Phil27099]

Savage x ou revo 3.3. Quelle est le meilleur?

[@jose887000]

Wow mike that thing is flying !!!!!!! Mike which mamba you think is the most faster for 1/10 turing car

[@Darth_Stig]

Hey Mike, great video. I've got a question for you, I just bought a Kyosho buggy with a 2200kv motor with a MMM ESC, and I'm looking for the right lipo for it. I don't care if it's 4s or 6s, could you possibly show me a really good lipo (like the voltage and mah and any other impertinent information)? I don't know much about electric yet (trying to get out of nitro actually). I figured here is a good start. Thanks in advance!

[@beachcomber535]

Top work!

[@jlr6]

Got the same motor 2600 kv.But got a Orion Vortex R8 waterproof ESC.I run in dual 2s 20c 4000 mAh and it hauls ass.I got the new Castel battery connectors too.But they suck to pull apart,and connect. :)

[@Traxxasboy25]

@MikePeperni Good driving bud!

[@ananthkrishnan6179]

what are the things for need this

[@CygnusX250]

super cool, hint remove the spoiler/wing or plane it out that should give you a few extra mph...i got my vorza up to 92mph just by gearing (stock mmm and 2200kv, cheap china ebay foam tires) i had trouble getting it past 85-86mph then i removed the wing and that added 6mph..ohh turnigy 6S 5Ah 40C battery. i have been tempted to try 7S :-D, and people say speed runs are boring, i find fiddeling with the small details fun, and then getting to see it hit insane speed like that is just awesome

[@jojomoor]

@MikePeperni wow! well worth it thogh!..Bwt , is Peperni your last name ? I hear that often around Montréal. l love videos and can see you like good old Metallica ? ;) You got a new subsriber buddy!

[@petervelker1990]

do you think those ofna foam tires would fit on the new traxxas slash 4x4.

[@joshreynolds777]

where do i get one ?
