How To Set Up Your Losi Tenacity DB Pro For 3S LiPo Batteries.

This video shows you how to set your Losi Tenacity DB Pro up to handle standard size 3S LiPo Batteries. There are some slim 3S batteries that may not require this change, but most surface 3S batteries will require it. I was wishing it was velcro to go back and forth, but lets be honest...I'm only going to run 3s batteries and this is less hassle then velcro can be at times. So I take back my desire to change this. :)
I did a terrible job explaining why the motor will over heat. LoL. Basically it's over geared and will heat up the motor on long run times. Because I want to bash this, I plan to run as long as the battery will give me and don't want to worry about overheating. That's why I geared down. I'm not looking for the fast truck over short bursts. I want long run time with enough power for fun.

im a bit sketchy on doing gear mesh, bc last time i thought it was good but it wasnt. Good thing my hobby shop gave me some pointers! Now, i have the perfect video to help me with the process!

[@PHFishingBiking]

👍 Good stuff... can't wait to see it go on the 3s!

[@rw2king]

Excellent review.. All the other reviews I've seen they are complaining about the battery tray being too small without taking the time to look in the manual first.

[@CCxRC]

I was one of those people, but I did mention that they included the spacers to change it. Still, I prefer to not have to make adjustments like that to battery trays.

[@RcNickster709]

Cool Tony. Nice that they send you the kit to convert it..

[@CCxRC]

Yeah. It comes in the parts bag supplied with them in the owners manual.

[@operation11charlieinc]

I was looking it on 2s ,,, ufff 3s is going to be awesome brother,, Can't wait to see the running video bro

So it comes with the spacers?

[@johntag9511]

can anyone tell me about the Adjustable Differentials? looking to make one really cook and i did not no if there was say a speed kit that gave teh buggy a higher top speed. thanks

[@cadeblain2265]

Where do you get that electric tool kit??

[@ScottMcLinden]

Thank you Tony,

[@rgr4475]

Very helpful video, thank you. Quick question. Are there supposed to be no spacers where the hinge pins go through the front and rear control arms? I can slide the arms back and forth.

[@johnruss9660]

Free play for better movement I suppose, Less binding will give the optimal performance for freely moving parts, I just purchased one today 🤘🏾

[@mark-1rc502]

As for pinion mesh i always go by Sound if sounds right it’s usually right 🧐

[@sotorc1448]

If I swap the pinion to the 3s one can I run 2s on it or should I switch it back??

great info bud.

Thanks Tuga RC!

Hello. What is the differential O-ring size for TEAM LOSI TENACITY DB PRO RC car? Can I use 4.4X1.5 O-RING?

Just bought this RC and bought some Gens Ace 3s batteries, 6000mAh 35c, and I just saw they EC3, will that work?? They still shipping

[@brandonsmith4367]

Just got mine, when i went to remove set screw on pinion gear, it wont budge!! Im afraid im gonna break something. Its feels like they used red locktight or something. Any tricks???

[@vapeapetn]

Question: Got DB Pro today, 1st run...Ran less than 5min. Steering works, but...Get blinking RED light on ESC...What's going on? I'm so upset, 1st run, and $500 and can't get 1 battery to run. Plus bought a Spectrum S905 (8S Servo), to put in here...Where can I get a Servo box that will fit this?

[@netcruzer]

Hey I missed this one. Very nice to see the 3S risers are in the kit, and a 15T step down from 17T. I may try 17T on 3S... see how hot it gets! Lucas Oil Tenacity DB Pro on order.. my LHS won't let me buy the demos.

[@CCxRC]

It’s a really great RC. I am happy with mine on 15T at 48mph. Works in most situations for me.

[@vapeapetn]

Keep in mind, RtR, no heatsink and fan. So heat is more a issue...I'd suggest a heatsink / fan if persistent on 17T. Just my opinion

@@williamperri3437 lol I hear you man! I just got that Reeper and I'm really thinking of pulling the trigger on that Mojave! Might sell my granite to help fund it lol. But I really like this truck. Only reason I didn't grab it is my 3s typhon is somewhat similar. But it jumps and rides so nice.

[@cwatson42785]

@@williamperri3437 oh I hear you! Each time a new rc comes out I say oh well I can always sell this one or that one but never get rid of them lol. I wanted to 4s outcast too but the reason I didn't is cause I thought for a extra 75$-150$ you can get the big boy 6s beast. And for that little bit extra you get much more in my opinion, bigger truck, alot more beefier metal parts, nicer shocks, metal driveshafts. I wish the 4s models were more around 50$ less at around 350$..... Thoughts?

[@cwatson42785]

@@williamperri3437 Yeah I definitely agree on the shocks. I put some hot racing ones on my granite and I plan to put the 6s typhon shocks on my 3s. But yeah that makes sense about bashing on concrete at the skate park. Plus another thing I like is you can wash it down and not worry about alot of the metal rusting up. I've seen alot of used 6s trucks have alot of rust but then again they might not blow it down good and lube it up after washing it.

[@cwatson42785]

@@williamperri3437 Yeah the hot racing works good. You need bigger ones in the rear than the front. If you decide to get some I can give you the part #s or the measurements of the ones you need. They definitely make a difference. I also can give you the info on some orings you can get from lowes that are a little bigger and help solve the stock shock leaking problem. Instead of being inside the shock body they are a little bigger so when you tighten it up it seals it a little better. If you ever need that info just let me know! 👊

[@johntag9511]

so i take that the small gear also gives the buggy higher top speed to right?

[@zevi2000]

Smaller pinion means lower top speed but more acceleration

[@ryansteeves3501]

Ty so much for this. So easy. And I'm an idiot. Lol. A million times easier than my Arrmas.

[@rlosito91]

Quick question got this car did the same upgrade as you but my run time is only 20 minutes until the battery dies is that normal? I’m running a 3s 8000 mag 100c lipo any recommendations?

[@CCxRC]

That’s about right if you are running it hard.

[@cwatson42785]

Tony what bits do I need for those small power screwdrivers? Like what size would the chuck end be? For like the ryobi or black and decker one? Thanks

[@donmichaelcorbin4417]

Most impacts and such are ¼" drive. You can get a ¼" to 4mm adapter that will allow you to use the small "precision" bits with them.

[@cwatson42785]

@@donmichaelcorbin4417 Thanks Don! I had actually grabbed a skil brand cheap one that I'm happy with. Yeah I wasn't sure what the drive was as I'm used to full size drills with the tightening chuck.

[@RCPropaganda]

I need one of those screw drivers, sick of using the big old drill.

[@CCxRC]

I started with a Black & Decker one from Walmart over 15 years ago. It's my most used tool around the house. I now have 3 of them.

I love having a 3d printer, i just 3d printed and taller mounts and was good to go. I should add that I have a Losi SCTE 3.0 same platform but because its for racing it doesn't come with those parts.

Cool I wondered suppose to use smart battery for orange esc?My friend use regular the battery then mess up the esc is not work😯

[@CCxRC]

As long as the battery isn't overpowered for the ESC it should be fine.

[@jonb2613]

Doing something wrong I guess. Can't seem to release the large pinion gear despite removing the grub screw and ridiculous prying. The screw with washer to remove is closest to the outside edge of the chassis on mine. Not so in your video. HELP

[@jonb2613]

I machined a puller tool to get the original pinion off.

[@AlexHT100]

Day 1 of DB Pro… rounded out grub screw trying to change the fcuking pinion over for safer 3S use!!! Now I’m stuck :( any advice?

[@CCxRC]

Drill it out and get a new grub screw. Most people just keep running that pinion on 3s

[@AlexHT100]

@@CCxRC how nice that you replied on this old video! Thank you. However ran my 1st pack through it (well 1/2 a pack) and it was running HOT! Way too hot to touch. IR temp gun on the way so I can monitor. Do you know how hot is too hot? Thanks again matey

[@ShenRC]

Nice job! gotta see it rip on the 3s!

[@CCxRC]

It comes alive on 3S.... Unfortunately, there are workers at the site I went to last time. Couldn't get in a run there on 3S. Maybe after hours I'll head up there 😉

[@michelecannata4158]

Why do you need to install the pinion gear?

[@CCxRC]

You don’t have too, but the motor will run hotter with the larger pinion and more power from the 3s battery. Just watch your motor temps to make sure you don’t overheat it

What size gear was it how many teeth

[@mark-1rc502]

I never bothered either ? Then I bought some huddy allen tips to fit into a Chuck , now I always use my 18v cordless drill 😱 I loosen off by hand then unscrew then rapid , as tighten I set the torque to the lowest it does the job ! Even the wheels I taken a socket and now I got a wheel gun too like a tyre shop . 😂 saves the wrist for other things Lolz

[@jdpasl]

@@mark-1rc502 I think I would get the Ryobi motorized screwdriver.

[@mark-1rc502]

jdpasl You can do if they’re cheaper ? I’d personally look for something more useful for other stuff too? I had an old banger 14v Chinese cheap cordless drill that needs charging one day before you intend to use it . I found with my new one and the old one that torque setting one is about how tight you’d make it by hand anyway in some cases you can use torque setting two, it just gets to a certain tightness and clicks it doesn’t tighten anymore . But for motor pinion is always use hand tools . But unscrewing Diff housing etc from under the chassis it’s a time saver .

[@cchhiillaannggoo]

I bought this car and I put the smaller pinion to run a 3S battery and I feel that the car doesn’t move very fast at the beginning is that normal?? Once it gets some speed it moves fast

[@CCxRC]

Sounds like the AVC may be holding it back at the beginning? Have you tried disabling it?

[@cchhiillaannggoo]

CCxRC it was completely off

[@vapeapetn]

I'd suggest trying a ESC reset, sure couldn't hurt man. Still have the manual?

[@scottyfpv5651]

Well the batteries I have are too damn long..5000mah 3s. What the hell do I do about that? Wish they would have thought about that bc there's no way I'm buying their $130 "smart" battery.

I hear you. I'm not a fan of all the different sizes and shapes of batteries coming out.

I just got one of these so I can drive with my wife as she has a slash! Anyway I'm running 5200mah 80c hoovo hardcase lipos with the ec5 connector already on them and they fit like a glove!!!! All my other 5000mah 3s for my planes are too long ugh! Good thing is these hoovo are cheap like 28 bucks cheap and so far make this buggy rip!!

[@vapeapetn]

Lucky for me all I run are Spectrum Smart Batteries, and the 3S Smart is $92 on Amain, not $130...So really no higher than the other brands man. I tell people all the time, stay within your eco system when going RC, or you can go broke for sure.

[@edgargonzalez-jq9jq]

I use 4s with stock motor and esc 😅 no heating issues you guys have no idea what beast means yet.
