Default RC8BE Short Course Conversion Motor Question

I ordered an 8.2BE from Tower along with the SC8 bumpers. I will be running ROAR legal DE wheels and a 1/10th body. I want to stay race legal at my track under the 7.4v pack rules. We can run 540 or 550 motors and I'd like to run in Mod. ESC will be either a MMP or RC8.

What motor would you recommend for a 7lb truck?
I have a 4000kv Pro 4 on hand. The track runs 1/5, 1/8 buggies, MT, and SC. It is medium sized. Is this motor
going to fry itself?
Would a 60c rated battery be enough?

Doesnt really make much sense to run 2s in such a heavy car

I would try a Castle 1512 2650kv

Cheers

So there isn't anything sensored?

Perhaps a Tekin T8 motor

Will not be very responsive on 2s however

Try the viper 4.5XL motor. Its the only thing I think would be up for the task. Its an XL can, considerably bigger than the sc4x tekin, and better power than the pro4 with good temps. Its sensored, and ultra smooth. I have tried all the motors, and thats what I would suggest trying. I have a rc8be, but never tried anything like that with it...I can only speculate how it would perform. I think it would do pretty well though.

Yeah I don't see this working.Heavy truck+little motor=hot,hot,hot!I recently converted my RC8BE into a 1/10th scale SC,using 1/8 electronics of course.I only did it because I had all the parts laying around and I was bored.It was fun but it's better as a buggy.Problems you will have will be mounting the rear bumper,and getting a body that will clear the front tires.Maybe a blitz body?This conversion would never be legal to race around here,I brought mine to the local indoor track just for practice and the whining started right away.Its too heavy,you might hurt my truck,waah,waah,waah!The only thing I hurt was the plywood curbing on this one corner,got outta shape,center punched it and snapped it clean in half!Good luck.

I can say for sure, the sc10 4x4 would be faster on the track. I did run my rc8be as a sct once, it was terrible. It went from hooked up buggy, to a terrible sct truck. I was running 4s.

you need the Tekin Pro4 4600 to push that heavy truck around on 2s.

Tekin Pro4 wont push a 1/8 buggy at a decent speed without getting hot

Even a 4 pole 550 (Tenshock SC411) will struggle

He will need a 1/8 sized motor and it will draw silly amps on 2s when geared for a decent speed

Cheers

I dont see the point in this. why convert an 1/8 scale and want to run 1/10 electronics?

Allow me to be more clear. I'm all for custom conversions and all but with more weight you need more power. Though similar in size the weight is very different. Thus in my opinion you will need at the very least a 1/8 motor/esc running on 3s.

I am not trying to be an ass here, but I'd hate to see you go threw all this work and fry some expensive electronics.

No problem with your questions. I plan to run the MMP or RX8, so the speedo won't be a concern. I am curious about what motor I should run. The chassis does have a bit of static weight, but dropping pack size should decrease weight a little along with some chassis mods. I can always run it as 1/8 ebuggy later, so my greatest risk is frying a motor.

So again, with an RX8 on 7.4 60c, I'm collecting as many motor suggestions as possible.

Then at the least maybe a T8 2650 as sugested be crusey. If you are going to run an RX8 get the combo from Stormer hobbies. I think they have them for 279. That means your getting the motor for 79$. Then if you do run it as a buggy, you can still run up to 4s. If you plan on racing at you track in a series of some sort just make sure they will allow you to run your setup.

Tenshock could be an option allthough he wanted sensored so it would be the X812 (new release)

My X802 2400kv works ok on 2s but feels a bit sluggish

The 1/8 motors absolutely will not work on 2s, dont waste your time or money.

The pro4 will do it, its going to be on the hot side.

The viper 4.5XL motor will push it on 2s cooler than pro4. Its the size of an 8th scale motor, but wound for 2s. it is what you are looking for.

The buggy is not as heavy as people are making it out to be, its just a tad more than the losi scte.

So my 4000kv Pro 4, on an RX8, with a 60c + pack, stands a chance if geared low and cooled?

Give it a go but I'm betting it runs too hot anywhere near 35 mph

Cheers
