You should be able to set the g sensitivity to stop any false positives. |
I was thinking in terms of an 8 pin PIC and a few lines of assembly code. It shouldn't be too hard to differentiate inclines and bumps from actual deceleration.
Digi-key sells brand new accelerometers for $5-$10. Wii Remotes tend to be to expensive.
Nice helicopter by the way.
