Yea I hear ya, now that I have my on road and still tuning it I ask myself if I should build a off road one, but, I have a short course truck I just built which is a kick to drive, dont drive it much, no place to. so I'm happy with them all.

Thank you. it's getting more bells and whistles

So i finally made the move to build an on-road. I decided to get away from using an emaxx and start with a truggy base. Pretty much i kept the truggy center and changed the arms cvds and shocks out to buggy ones. This pretty much saves me the time/money from having to get hybrid diffs for my emaxx as well as having to CNC parts. Its currently only powered with a novak hv6.5 on NiMh. I have a Mamba System in the works but I need to get the lipos before I run it on the mamba.

With its current setup probably 45 tops but even know torque is great. Can't wait to get the Mamba in there.

For the future I hope to add a kyosho gt 2speed gear box in there.

By the way heres the link to my build http://www.beatyourtruck.com/forum/s...-7-scale-HB-D8

Also where do you run your 5th scale? I heard that down in Santa Clara there's a group of people that are running NITRO Inferno's. We should go show em who's boss lol with a brushless rig we can smoke em in every aspect.

hell yea... can a give better step by step on how u fit the 1/5 wheels on there?

im in the process of doing almost the same thing u have =)

You could try to install LST XXL shafts on there. They might not be the exact length you need but you could modify them like you did for your center shafts. You probably would be able to reinstall the original output cups in your diffs. You're pretty good with that drill press so the axle carriers have to be modified just by enlarging the hole for the outer bearing to just under 16 mm. Then you can press a 8X16 bearing in there. The inner bearing is 15X21 and you can press that in the carrier with a 5/8'' socket wrench and a vise. It slips right in.

I'm not sure about your wheels, I went back to try to make sense of how they are secured on but I can't figure it out. I don't know if the wheels use a hex drive and how big it is. I think I read something about them having a square drive?

Can you tell me what you made your chassis with and how exactly you made because im doing something similar in my machine shop class except using 1/8th scale buggy parts.

thanks

can u tell me what tires and wheels u have ??

found em'!! lol, to bad there out of my price range :(

[littleazn248]

You've made some really good progress! So have you managed to find a body yet? Just curious but hows the 1515? Does it give enough umph? I also have one suggestion you should add some disc brakes on the front wheels. It's easy to find em for a 1/5 scale.

Nice job!! Glad to see an old build revived!!

Finally owner of a Rc Monster Slipperential

Spent maybe an hour with assembly, but need diff oil.

So what is the math behind figuring out what Weight oil to go with?

I have on hand: 2k, 5k, 7k, 10k, 30k.

[SpeedAssault]

Oil
7k front
10k Center
5k Rear

Thank You RuuDxD

Even Castle did not know Power of 2200

Based on 120Amps:
2.84 ftlbs of Torque
Axle Torque 3.81
2.8 to 3.5HP
6S 25volts
Tire 4.8
Spur/Pinio Ratio 2.41:1
46Spur 19P
Theoretical Speed 78MPH
Calculated Motor Power 3024 watts (4.1HP)

At Under 11.5 lbs this would explain why the car from dead stop it Jumps straight up in the Air when Pull full throttle.

Trimmed down power, ran good.
car sat for couple yrs
Problem Now, throttle Stutters in begining, , give it a push and drives fine above 8mph. ??

No need to thank me, I just copied and pasted a link, thank BrianG, the maker of that site!

I could be wrong, but that could just be the sensorless motor trying to find the right coil.
It is called cogging, it looks somewhat like this:

He does run very little throttle in the video, so it is worse then when you accelerate faster.
It does get worse with heavy gearing if I am correct, so that might be something to?
If you run a lot on low speeds, or want a smoother power band, you might want to consider the new Sensored Castle Combo's?

I am not that knowledged in RC though, I am trying my best, so you might want to have this second checked :)

Sounds like the capacitors on the speed control may have crapped out... You may need to add a cap bank to the main leads, or possibly replace the caps. Heat and time are enemies to capacitors.
