Tried out a 11x5 prop today which seemed to be ok, its a pity i almost lost the model, due to bringing back to the pitts after 3rd flight to notice the engine felt loose

right... take cowl off, to find out there was only 2 bolts left holding the engine to the mount and the needle valve had stripped right off the metal plate which didnt seem to good either, ohh well back to the drawing boards to repair lol..
