Regarding the Canister size, the pathway is about 2.15" (54mm) in diameter. So the 50mm DA50 canister would work, if you choose to go with a DA50, if you use another motor, a canister of similar size for the motor you choose will also work.

I have called you guys and sent numerous emails. Will someone please contact me about a problem I have had on my banshee. It's really frustrating when you purchase a 1000 dollar plane and no one seems to care about the customer service!!!!!!!!!!!
