Speed Control for Balancing Vehicle

[sanddrag]

I was looking for a speed control to use in my balancing vehicle (like a segway) project. You may have seen in my other thread that I got forward only ones without realizing they were forward only. Instead of trying to make a relay switch really fast, I figure I'll just sell the one's I have and get the proper reversing one(s).

This is made to plug into a standard RC receiver. I will be needing to control it with a BASIC Stamp.

1. Is this possible?
2. Are the signals the same? Or will I need to use Parallax's PWM Pal?
3. What about IFI's pwm signal booster thingy? What does that do?

It is my understanding that this controller has a brake feature that cannot be disabled.

4. Will it still work in my balancing vehicle or no? Will any special programming have to be done?

5. Last, if anyone knows of any comparable or better controllers for a lesser price, please inform me. I am on a budget here.

Thanks in advance.
