Which Firmware....

.... would you recommend for this.

Bought used from ebay with no instructions unfortunately.
Not been able to get it to start, let alone take off so far.

I've owned this particular unit... It requires a seat, and an on board pilot. The best method for launching this is by hand (think boomerang).

That’s the AggieTex CincoCopter, Model N0Fli-1, Beta version. It’s designers couldn’t figure out why it wouldn’t fly, so it was converted into a more suitable office chair base.
