OMG some 1 try this :D. I don't have flies for the next 4-5 months here so you go ahead.
I found some comments (here):
-Tried it with bee's and popsicle sticks worked awesome just had to have a piece of thread attached to it so they didnt go too far.its hilarious how some fly and some dont so it wobbles thru the air
-tried it, it works kinda, the engines run out of fuel really quickly
