I don't have anything to weigh it with accurately. If I had to guess, I would say 5.5 to 6lbs. The Great Planes Corsair is considerably smaller than the TF Gold Ed. Corsair. I have a buddy who has one and he uses an OS .91FX which is a great combination. Very fast (for a .60 size Warbird); guessing around 120 to 125. I can't remember for sure but I believe he is using a 14X10 prop. I would have thought that was too much prop but it seems to like it.
