SJN I have a Saito .91 FS and don't need more than 1/2 throttle to take off and fly. That engine may be on the low end of pwoer, but should do the trick. You will most likely have to add a LOT of weight to the nose to balance I have 2 1/2 lbs of ballast it the nose , but weight is no problem as mine still comes out at 9 lbs and 17.5 lbs / sq foot. There are a number of sites for the Camel, a good one is from Rhinebeck ( do a google search) where they fly a replica with the rotary engine, don't sound to healthy, but more than enough for the plane. Check out the other Camel threads in this forum, you may have to go through a few pages before you find them, but they aree there still. Nice plane and if you can handle a Cub, you will be pretty much able to fly this one.
