well i know about brushless. i run an lrp system in a TC. a mamba max 4600 in a DF-03, and a vxl system in a rustler. and for a while it was in a maxx. so if i go with the 7xl ill have decent speeds and enough torque to lift the tires off the ground on 3s. and once i can step up to 4s it will be insane? more in the 40-50 range than the 35-40 range?

I can say that a 7xl on 4s is a fast setup. I gear all of my vehicles for around 40 so It all depends on motor speed. Keep the motor speed below 40k rpms and it will run well. Any more than that and the feigaos start making alot more heat.

what about on 3s? and what kind of acceleration will i see? gearing? i would like to go ahead and get different clutch and spurs if i need to. order it all at once.

That is cool. A lot of people have great success with that set up.

You really can't beat the price of a Feigao. You can have a Feigao and a RC-M heatsink/clamp for half the price of a Mega.

This is true. I love the look and everything I've read about the mega, but I have an 8xl and am very happy with it. It's strong, fast, and tough. ESC's however, I have much less luck with. I've been through 2 quarks, 1 mgm, and one MM, all fairly recently. :|

The MM is a fine controller, but it's prone to blowing caps. Adding a few caps doesn't hurt, and running a BEC or RX pack will help keep the temps down. Keep a close eye on the temps. They don't thermal soon enough, so you can do some good damage from heat before it turns itself off.

It would be nice if Castle let you adjust when it shuts off via the CastleLink.

alright well i have a temp gun so temps wont be a problem. im makin my order this weekend. im going with the feigao 7xl, mamba max, and tekno kit. and you sure this is gonna rip on a 3s? i mean i know it wont be fast. but 35mph and getting there in a wheelie to me is ripping. atleast in an mt. cant do much with MTs at 45+mph so 35 is fine with me. and wheelies has to be there:whistle: haha. still no one knows if it will lift off the ground?

It should.

should isnt a word i like to hear when im about to drop $400 into a truck.... if it does with how i gear it(18/36 probly) than i will just drop a few teeth and a little bit of speed. thanks for all this guys. lookin forward to a nitro killer

Well should is as good as it gets from me. I'm not gonna say it will, when I don't know for sure. Like I said, I have a center diff in mine, which prevents wheelies. I'd rather not say it will and then it won't. Besides, 18/36 will probably fry something instantly. Try 14-16. Mine MM gets rather warm on 16/36 with the internal BEC in use. Everything else is stone cold. I was gonna order a 14 and 15, but there out of stock...

well i will probly be using an external BEC, even though im only on 3s for now. also will have a fan running which will help. but hey if it doesnt wheelie. if anything it will launch harder than nitro right? because even if it wont lift up, if it will outdo a stock revo or t-maxx from 0-30 than its fast.

I've seen a coupld videos of Rvos doing what you want with the L motors. So the XL will do it.

Also take into account my ESC settings. I set my throttle curve so that it doesn't start accelerating until about 1/2-2/3 throttle.

which slows the power curve.... so on stock linear power band it should be plenty of acceleration. thats good. thanks guys
