The servo goes directly to the receiver.

Looks nice and low, good design.

If we can get it ready in time I will take NPOW with me, Katjuscha's 6 kg bigger brother for display.

Cool idea, like killerhz did.

In theory Katjuscha is also in that range, but because i cant really hit when I spin that fast it will be less then that.

Having a lot of KE is nice but you need to transfer it first. The new DBA's disk will be much better at that than mine.

the last one is correct. You only need a speed controller if you use a regular motor and not a servo motor. A servo motor already has electronics on board to accept the receiver signal and convert it.

Which one?

if you modify a servo to make them rotate, you can put those on the receiver and you can move without speed controller.

for normal brushed motors you can use speed controllers or switches+relays to activate them.

A speed controller gets a signal from the receiver, and accordingly it will move a motor in a certain direction. it gives you more control because you can increase and decrease the speed of the motor. The other option is an r switch and relays to control a motor, but thats more a full throttle off k...

And the + and - are reversed on the charge plug, so keep that in mind if you buy another charger.
