RE: WWI Bipe for a .70 4-Stroke?
A fellow Club Member has a Flair Puppeter with an OS 70 FS in it and it is a super flyer. He comment is that it is a bit over powered but the extra weight of the engine helped with the balance. He flys it at 1/2 to 3/4 throttle most of the time and it is very scale like in the air.
