well I had to bid on about 5 of them (different ones) before I actually got one. The main one I was after had the controller with it but I got outbid.

So that brings me to my new question, Dose any one know how to mix them so that I can drive it with only one stick?? Like on the scooters that have only one sick that turns and back and forward.

You can buy mixers for radio's to go in between the speed controlers or servo's and reciever, but if you buy a duel speed controler (eg the IBC) it may have mixing built in, some high end radio's can also support mixing from the radio itself. Smile

Most decent dual motor controllers have mixing built in. With for instance the sidewinder you determine the type of mixing with jumpers on the board. Tank steering, single stick (standard, and the one i prefer) or mirror mode (both motors do the same).

If you have a transmitter thats supports it you can choose to do the mixing on the transmitter itself.

And there are several v-tail mixers that go between your receiver and speed controllers, and mix the signal for you. This is usually for mixing 2 single motor speed controllers, and if youre transmitter cant mix.

So there are several options.

What would you suggest? Is there some way I can build it myself?
I'd Like to buy the speed control from this website but I just don't have $300. but it dose need to handle really high amps. Shocked

There are alternatives, you can use microswitches to control the motors, pushed on and off by standard radio control servos. That works but is not proportional control. The proportionate triggers in cordless drills also can be hacked. Both are tedious though, and not as safe as a proper speed controler (can go out of control) Smile
