The only reason i went with the webra.61 instead of the k&b 7.5 is because the p47 has a big firewall and i wanted to get more prop out side of the cowl. I could be wrong and this not work but i gotta try it. This webra was in the electric gp proud bird i built 2 the first one broke the wing and the second on the first flight it started moving so fast it flutter the wing and striped the ale servo. Stupid me did not go with metal gear. Oh well live and learn.
