Thanks everyone for the replys! Sorry to keep asking questions, but I am 110% electric noob. Is a 120 amp esc a good fit, or to much? Also wondering about motors numbers.. I want something with enough top end for watsonville and enough torque for Nor Cal. I read 10.5, 6.5 previously posted, but lost also the kV thing.. Getting confused, but trying to learn and dont want to buy the wrong stuff. kinda the "measure twice, cut once" thing..
Thanks again all for the help!

I've heard of Losi 22 owners raising their transmission by 1mm to improve traction and acceleration coming out of turns, but I can't find anything that explains why the improvements other than it helps with bone plunge. I've raised the tranny in my 2.0 and 22t, both MM, and have noticed positive results. This leaves me wondering if raising the tranny in my b5m would be advantageous??? Has anyone tried this?

Id be curious to know the reasoning behind it because to me raising a transmission and the motor attached to it by 1mm is raising your cg by a mm.

Mid to high traction: Mm rear arms are slightly more forgiving and less twitchy . Rear motor arms are slightly more hooked up and respond faster.

One would think it raises the center of gravity, but the benefit I believe comes from the difference in resistance between the dog bone with the out drive on each side of the vehicle.

In a turn, the vehicle rolls to the opposite direction of the turn. We'll use a right turn in this example. As the vehicle turns to the right it rolls to the left. By raising the transmission it would decrease the angle of the left bone in relation to its hub. Conversely, it would increase the angle of the right bone too its hub. I'm no specialist in physics, but wouldn't this create more drag on the right side of the vehicle thus transferring this drag to the tire and help to stabilize the vehicle in a turn? Wouldn't this also help to transfer more power to the left wheel since the left bone would spin more freely than the right?

I think this is the benefit Losi implies, but I can't find any write up stating this.

Like the ^^^ post said Petitrc.com. However, they have lots of setups for modified, but very few for stock and they don't seem to be very consistent. Start with the kit setup, add the flat arms (I picked up more steering using the flat fronts), and go from there. My local track has lots of great people willing to offer advice if asked. Hopefully, yours is just as friendly.

Also, at Petitrc.com under Technical Review > Off-Road > "Process to set up a car" is a great tuning cheat sheet that I've printed and keep in my tool box.

heres a pic of Watsonville

Beautiful! Pretty sure the wife would like to hang with me at this one....

3 gear was pretty good yesterday. I made some dumb mistakes but this car on a higher bite track with the 3 gear is pretty darn good. For all those that thought the motor rotation was gonna make your car do funky shiz in the air... it never did anything weird no matter how hard I tried for testing purposes. It flew better than the 4 gear and and has more on power steering. Win Win in my book.

It is. And a couple of the guys running stock expert are turning the same times with this new layout as the mod guys. The fastest stocks guys were faster than mod on the last layout.

on power steering, that is the one place I feel my set-up needs help, driving is my problem . If I push to hard on power it will push more then I like.
