Yep... a 72 would be fine.... this thing cruises at 1/8 throttle with the 82

I tested today and got 30 minutes on my 12oz tank.... so.... a 6oz should provide 15 minutes

Also my 82 is new.. I am on my 4th gallon of fuel so fuel consumption will get a little better

I guess I will try the 6oz I have in house next and see how that feels before buying an 8oz

Check me on my thinking here... I am about half crazy (retired pro drummer)

LOVE the plane!!!! Tumbles nice... flat spins both ways quite well.... great high alpha knife edge
