Sorry for all the questions but brushless is all new to me and I wont miss my brushes and no more comm cutting,cleaning etc...

speed passion all the way u can get them at racing-cars.com

Yeah, i usually have plenty of steering too. Might give it a shot for the next time i race, and for the next FTMS race.

Now the b4 on the other hand, im lookin for steering on that thing. It pushes like a mack truck with flat tires. Odd for a b4!

And if u do think the spx, why? What's the pros and cons?

Although I like LRP my suggestion would be the tekin RS or RS Pro - Lowest "on" resistance and most programmable and updateable (with hotwire interface) basically its the last speedo you'll have to buy for a very long time because updates to the software are downloadable to the speedo, you can adjust voltage cutoff, timing advance (in the speedo, not just on the motor), neutral width, brake strenght, push control, drag brake, and more..

The hole sizes are well known, AE's are 2-hole pistons, Losi are 3-hole. Less known is that AE pistons are a "loose" fit in the shock bodies, Losi's are much closer fit. This partially negates the hole size..

About Tekin's on-resistance, I read a while back when they were challenged about the difference in resistance between the RS and RS Pro that with the RS, the specified on-resistance was lower than the solder joints of the lead wires.

Now IMO I think that if AE wanted us to use losi pistions they would come with the Kit. Now I know every one has there own driving styles, so what does the losi pistion help with, I see a lot you people use them and like them?

grinding noise

I just built my T4. It runs smoother than any truck Ive run before.

When I spin the wheels with my hand it sounds like it grinding or rubbing. Is this normal? When I spin the wheels the spur and pinion are meshed.

All esc manufacturers rate their on-resistance on a theoretical level taking the individual resistance of one fet. The actual on resistance is higher for ALL esc's on the market.

For you that want to run the gear diff off the sc10 you will also need the sc10 diff housing, diff housing bearings, and rear pivot plate. They are different then the T4.

I have both sc10 and FT T4 so I compared.
