I DOUBLED The Power On The 4s Arrma Outcast V2.5 And It's AWESOME!

[@mshane86]

Finally an RC channel I can watch on normal speed.

[@DoRC]

Glad you enjoy! One of the main goals is to just give you the info you need without a bunch of fluff :-)

[@DerbyCityRC]

Super cool and helpful video man! I love this new truck but yes that servo saver blows!! Mine got loose within 4 packs!

[@DoRC]

Yeah hopefully a good aftermarket upgrade becomes available soon. They're already a couple of options but none of them are ideal. The market is definitely ready for a good solution.

[@Nutz_forRCs]

Had the same issue with the straps bashing today. Batteries kept popping out without enough Velcro touching. Then realized i was doing it wrong - you need to take the loose strap over top of the ‘plastic tab’ BEFORE feeding it through the hitch. Then the strap sits on top of the plastic and has plenty of contact to hold. Seems obvious in hindsight… Also, the Kraton is a beast. Don’t think you can go wrong either way.

[@DoRC]

I'm not sure I understand what you mean. I just ran the straps the way they came from the factory. My problem was that with the plastic pieces on top the straps had to go down the side and there's almost no room there with the batteries I was running

[@Nutz_forRCs]

I didn’t pay attention to how it was when it came from the factory. With the battery in I threaded the strap under the plastic so when it came out the plastic was between the two sides of Velcro and the only contact was if you tried to tuck it down the side where there’s no room. You’re supposed to put the plastic down directly on top of the battery, then thread the Velcro over the plastic and through the hitch. Then the Velcro - the hook and loop - are both sitting on top the plastic and the straps work like normal. I had the plastic separating the hook from the loop so there was no contact until i got past the plastic and all I could do was try and stuff it down the far side where it could stick. With the plastic laid flat against the battery (fuzzy side sitting face up on top of the plastic) it’s no different from normal except there’s some structure to help hold it in place. Does that make sense? Is the the issue you were having or something else?

[@DoRC]

@user-ql6dm8xh6q okay I see what you're saying now. No The main problem I had was that the strap that didn't have the wiring connected to it didn't fit properly on top of my battery so I would end up just having a corner of it touching the battery. That and the front strap broke pretty much immediately.

[@RC-Kwagga]

Great video brother. Those backflips are vicious man! Can’t decide on the new 4s outcast or Kraton

[@DoRC]

Yeah I've had some pretty wild cars over the years but I believe this one takes the cake for fastest rotation speed in the air. I've never gotten a 5X backflip off that ramp before.

[@aaronsnider5558]

Hi, I'm wondering what kind of filament you recommend for your RC parts. Would you ever print something like a steering hub, or would a printed one be too weak?

[@DoRC]

The best material if you can use it is TPU. It has very good layer adhesion and the flexibility to be pretty durable though of course it's not appropriate for a lot of applications. Unfortunately many things like hubs will probably never be 3D printable because a 3D printed object is always going to be weaker than its injection molded counterpart. PCTG is pretty strong and I think Bambu recently came out with something called PPSCF that's supposed to be crazy strong though I've never tried it and it's very expensive.

[@MegaDeth859]

[@Frumba57]

What did you need to do to get the bigger battery in? Or did your 6s just fit?

[@DoRC]

Nothing. The battery in the video fits without modification

[@Frumba57]

Nice. I broke both of my battery straps during two separate runs at skate park. I make videos. But yours are top notch. Keep up the great work.

[@DoRC]

@@Frumba57 I did replace the battery straps but that happened before I went to 6S. The stock straps are always kind of crap.

[@Boogie_the_cat]

4s times two equals 6s My math demon would be proud.

[@DoRC]

Power isn't just the voltage. It's voltage x current.

[@Boogie_the_cat]

No offense meant. It was supposed to be funny, the joke being that I'm terrible at math. Ohm's law will always be a mystery to me, because I hate numbers.

[@DoRC]

@@Boogie_the_cat no problem. A lot of people don't take the additional current into account :-)

[@caspfornia]

Was that five or six backflips pretty darn cool 😎🥃

[@DoRC]

Best time manage was 5X. I tried for more but couldn't quite manage it with my ramp.

[@GreatLakesRC]

Wow! I’m really impressed that it held up to 6S power. The previous version with the slipper clutch probably would have failed. I bet 5S would work well 👍

[@DoRC]

I did run the previous version on 6S as well and it did survive but I got a little twist in the rear axles.

[@rubberducky531]

Where did you get the 3D file for the adaptor plate for the bigger ESC.

[@DoRC]

Thingiverse

[@martyncrease8289]

How come you change the connecter on old esc then swapped the esc

[@DoRC]

You know as I was swapping the ESC out I was asking myself the same question. The reality is though that whatever vehicle that ESC ends up on I'll still want to have just one connector on it so It wasn't wasted effort.

I did a 6S 1900kv Spektrum setup with a slipper eliminator on my V2 4S Outcast. 5 diffs later and countless driveshft later I went back to the stock 4s system. Super fun on the 6s system though.

[@DoRC]

Yeah without a center differential I definitely wouldn't recommend it. The center diff makes a huge difference

[@kaleoj1635]

Yo the center Diff in the V2.5 is insane @grant, also look up m2c parts he makes a BEEFCAKE kit that’s all aircraft grade aluminum replacement parts! Wont ever break anything on your outcast again guarantee. 10/10 recommend!

[@CrystalPlantz]

I agree. Probably would have been alright with a center diff instead of slipper. I went through a few diffs and axels with the slipper version. I upgraded it to the center diff. Havent broke anything in the drivetrane yet

[@DoRC]

@@CrystalPlantz yep. There's so much more stress on the drivetrain without a center differential.

[@Israelite-iq1gd]

Wow, I'm not going to lie. That looks to be more fun than my Outcast 6s 🫨They must be quite a bit heavier; it reminds me of the Jambo.

The smaller lighter 4S cars definitely have their benefits!

[@3SonsRC]

Curious if Arrma just scaled up these exact parts would it hold to 1/5th scale plastic rig?

[@runnerbaba]

7:52 these grey plastic battery connectors break way too easy. I use xt90 and sometimes some foam pading/ductape around them.

[@DoRC]

Yeah they do tend to break after a couple sessions. I'll usually put a big piece of heat shrink over them once they start to crack.

[@colorado_a3766]

Don't forget to do an overpowered video on the mt410 2.0 dude! Great vids as always 🥂

[@DoRC]

Yup. It's coming :-)

[@lukerecore]

I'm glad u left the stock 2400kv motor, and hell ya 5s. Bcuz I had a 4s kraton v2 4s and I put the 150amp and 2050kv into it. And it twisted the slider cvds. And I never ran that truck on 6s.

[@DoRC]

I think most of that issue will be ameliorated with the center differential. Without a center differential The rear wheels are experiencing the full power from the motor all of the time. With the center differential, even with really thick fluid in it, that torque is lowered quite a bit.

[@ReactionRC]

Wouldn't double power be 8s?

[@DoRC]

Power is calculated by multiplying the amps and volts to get watts. The 16.8v 120 amp ESC is capable of around 2000 watts. The 25.2v 150 amp ESC is capable of around 3800 watts. That about 1.9x the power. I did round that up to 2x though.

[@ReactionRC]

Ok I see your calculating power output not input. Yea you did round up. Alright cool video! So in all actualitie an 8s truck puts out more than double 4s truck? Like 3 times power? Am I correct?

[@DoRC]

@@ReactionRC It just depends on the best vacations of the ESC and of course the motor. There's a lot of different ways to calculate it and All of them are just going to be estimates. Personally I like the wattage capability of the ESC because that seems to the most consistent way to compare.

[@ReactionRC]

I see I see! Excellent. Thank you for the information!👍

[@shawnfreeman7802]

I'd like to see the difference on 5s! That would be interesting!

[@DoRC]

I think I run this one on 5S in a different video.

[@850RC]

What did the temp get to on the motor?

[@DoRC]

I didn't get a specific reading but I did give it the finger check a few times and it never got hot enough to be concerning.

[@850RC]

@@DoRC that’s great news. I was curious if the center diff was going to hold up, but so far they look to be tough. Can’t wait to see what it’ll do on 5s. Hoping it will give it a more manageable speed and punch than 6s.

[@Hungrybird474]

Mine is super quiet when throttling . It’s really pleasant and I can’t bring myself to hammer it yet . Maybe next week . I don’t like the extra connector so it’s going for sure sometime in the future

[@samuelkikkert4132]

what size straps?

[@DoRC]

The ones I put in there are just standard 250 mm straps but you might want to go a little bit longer as they're not quite long enough.

[@liewzy]

Did you changed diff oil?

[@DoRC]

Yeah check out my original video. I put 20 million in the center differential.

[@ed0c]

id go down a tooth or two maybe on 6s will help keep motor cooler and may help with the wheelie.

[@DoRC]

More power and a smaller pinion would actually make Wheeling more prevalent. That being said I like to wheelie!

[@gregmaggert8561]

What's the largest motor you can fit in there with a 6S ESC?

[@DoRC]

I think something like the hobbywing 1650 KV motor is the largest motor you can practically fit without a different motor mount. It's plenty of power though

[@gregmaggert8561]

@@DoRC I picked up a hobby wing 2000 KV 4274. Hoping it will fit without clearance issues

Really surprised the plastic drive axles held up to 6s. I had a big rock that I used to run on 4s and it would destroy an axle almost every time I drove it.

[@DoRC]

Yeah these axles are nothing like the big rock axles. I did manage to twist the rears when I did this on the original V2 but with the inclusion of the center differential they are holding up just fine.

[@ruuster83]

im debating on upgrading my Big Rock 3s to the Outcast 4s arms and CVDs because they are way better. but should i just buy an Outcast 4s? it would be about $200 to upgrade....

[@DoRC]

@ruuster83 I'd say yes. For an extra couple hundred bucks you get a whole other car. You could probably sell your Big Rock for the difference if you wanted to.

[@K5_RC]

Yeah the big Rock 3s has always had axle issues. It's because it's got the longest arms of the ARRMA 3S line and that means the telescoping driveshafts don't really have a lot of surface touching each half, so it over-torques easier

[@f.noggle]

The Big Rock drivetrain couldn't handle 3s.

No I actually removed it on the 4S ESC and then swapped out the ESC. Don't worry as I was swapping out the ESC I was scratching my head about it too. That being said I'm going to use that ESC in something and whatever it's going in I'll only use one battery.

Why can’t they fix the steering on these cars!! I’d buy one for sure if they fix that saver. Fun video! 👍

Yeah I agree. The same crap service either that they've been using since the 3S line first came out should not be on these trucks. I'm very surprised that no one in the aftermarket has come out with a really good replacement. It doesn't seem like it would be that hard to do and I feel like they would sell a bunch of them.

Yes you have to get creative if you're going to run 5S. You can either use an ESC that supports it or you can disable LVC and use telemetry to monitor battery voltage or just keep an eye on it some other way.

[@edwinlomonacofoolsend]

I have found that when I put the 6S ESC on the 4S rigs that steering improves quite a bit because of the bec voltage being higher.

[@DoRC]

The input voltage doesn't inherently affect BEC voltage. By being said certain ESCs have the ability to output 7.4 volts or even 8 volts while others are limited to 6 volts. In this case the stock ESC already can do 7.4 volts so there was no difference.

[@cj910]

Bigger ESC often Provide more amps to stall servos, so he isnt that wrong

[@DoRC]

Yes that's true especially aftermarket ESCs can't have higher current available for the BEC but be specifically said higher voltage.

[@danielkroeze8218]

5s would be cool but 4s is enough imo for this rig.

I completely agree. This car does not need 6S but it sure is fun! Thanks for watching :-)

[@tommygunnz450]

Double power be 8s bud

[@DoRC]

Not quite. The power is calculated by multiplying the voltage by the current and the stock ESC is 4S or 18.8 volts at 120 amps. That's around 2000 watts. The 6S ESC is 25.2 volts at 150 amps which is about 3,800 w. So it's 1.9 x the power and I rounded that up to 2x.

Second question related to gear ratio: 39/39 is the same as 34/34? One to one. Or is one more demanding on the system?

@@Frumba57 there's no practical difference. Argument could be made that the increase number of teeth could technically create more friction which would cause more power to be lost as heat but I don't think that is something that you would actually notice. Ratio-wise they are identical
