E-Wheelie: constant full speed, unable to stop without foot

[heikki_bohn]

Hey all

I have bought the Wheelie, and put it together, but for some reason, I can not calibrate the gyro, I think.

When I lift the Wheelie up, on some blocks, so that the wheels can not reach the ground, I try to tilt the Wheelie forward, as if I am standing on it. The wheels does start to circle, but quite fast, they move to topspeed, and the red diode starts flashing constantly. If I push the vertical steering pole to the left or right, nothing happens, the wheels are moving forward, at same speed. If I tilt the Wheelie backwards, the same thing happens, the wheels keep driving forward, and if I release the foot switch, the motors do of course stop.

Sometimes, if I tilt the wheelie just a little bit, it works, and I can navigate forward and left/right, but it requires the speed is about 0.25 km/h. Like real slow, slower than walking. If you tilt forward a little to much, it goes max speed, and you can not brake unless you lift your foot from the switch as described above.
One time I have tried to stand on the Wheelie, and controlling it slow, and then jumping off. As you may understand, I have no intentions on trying full speed with no control.

Do any of you guys have any ideas, to why this happens, and how to solve it?

I have tried to look the manual and the FAQ in this forum, for any explanation, of the red diode, constantly flashing, while it is uncontrollable, but have not found anything.

With free running wheels it is no wonder when the wheels begin to spin very fast.
This is because even when you tilt the platform very carefully the motor are given a current of - let's say 30W - to try to stabilize and they start to turn. But because the wheels have no chance do produce self balancing stability the motors is given more power and more power and it is very difficult to hold the platform so precise that the wheels turn only slowly.

Standing on the wheely is an other story because self balancing can work now.

But keep care to trust the self balancing abilities of the wheelie. i yo try to balance by your self you easily get a system where two intelligent systems (a controller and a brain) try to get control - what ends up in big oscillations which are not good for the rider nor the wheelie
