Can you stunt those red tanks or do they just feed off the bottom?
There' certainly not "full stunt". But I might be able to do an outside loop, lazy eight, and a lap or two inverted if it do 'em early in the flight. The tanks are pretty big for a 1/2A so I'll have some time before the pickup position becomes a factor.
On a 1/2 A scale job they're a lot handier than making a tank and finding a place to put it.
