i recently crashed the pts hangar 9 p -51 and had to order a new engine (evolution trainer) so it finally came this weekend and igot it all back together i needed the spinner also so i measured it and it was 2 1/2 inches so i went to tower hobbies and they had no red ones like the one that was on it just black so i ordered it so i could replace the white one that came with the trainer it was a dubro and the only 2 1/2 inch 3 blade i could find so it came today and when i put it on it fit great but the back is recessed more than the one that was on it and it rubs the cowl to the point that it wont hardly turn thought for a second it there was something wrong with the way i installed the engine but its not the case because the ugly white one works fine! by the way i did try to order the original from hobby zone but they were out of stock so any suggestions or am i just out of luck
