Twin Force Brushless Questions

[Gustav]

Yeah don't worry about the ratios.Sorry I was just having a go at figuring it out and then realised i couldn't.confused myself.

The 9920 is the one to go for.The Schulze is to be avoided by all accounts.they have a tendency to go up in smoke and shulze never honor the warranties.i actually have one unused which i would try to sell you if i was that way inclined.

Mike should chime in soon and basically you should go with what he recommends.

As for selecting a suitable pinion to start with just count the no. of teeth in the centre transmission.I think it's just a sprocket with a chain to another sprocket on the Twin force isn't it so just count the teeth on the sprockets and of any spur gears you have or can use with the truck and Mike or someone else may suggest suitable pinions from that.(sorry if you already know but pinion is the little gear on the motor and spur is the big gear that it spins)

Radios mostly come with a basic servo but usually aren't up to steering a monster truck.An extra $50 will get you a decent servo.
