hey there bmoc, if u are still working on that hvercraft, then pm me. I've built some hovercrafts before, any questions u have, just ask. neways, when u r looking for an engine for the <b>lift</b> motor, you dont need a lot of power, you need <b>rpm's</b>. The higher the rpms, the better! you could probly get away with a .12 lift motor. Another important factor is the lift propeller, experiment with different props, some may work 10x better (and I'm not exaggerating). old computer fans are very useful and valuable in this project.
