is this normal?
also i am now doubting the ball diff set up as there seems to be a strange whinning noise when on throttle.

ive never had problems running multiple nitro's and electric 8th scales, but this thing has me scratching my head.
Tighten the ball diff until u stop hearing that noise. Once u do that loosen the slipper.

If you still have the stock pistons start with 37.5 front 32.5 rear and you may want to try the gold spring in the rear.

I prefer to run 4 hole pistons with 1.3mm holes with 35 front and 30 rear, it makes the car better and can handle bumps way better

The local fast guy told me to use 25f and 20 rear losi, that seems low to me.

Just quick one, I decide to look at my weight %'s on my RM tonight and with a shorty all the way back my percentages are F=36% and R=64% is that about right on average?

Interesting. I'd have thought maybe more % rear than that. My mid motor is about 62.x % at the rear.
