THE IMPACT SHOWN IN THE PICTURES DID HAVE THE CRUTCH INSTALLED, THRER WAS NO PROBLEMS WITH THE RUDDER THAT I AM AWARE OF. THE AIRPLANRE ONLY HAD ABOUT 5 FLIGHTS. IT IS VERY DISSAPOINTING TO HAVE A PROBLEM THAT COMPOSITE ARF NOWS ABOUT AND THEY WILL NOT RESOLVE. I THINK IT WOULD BE EASY TO SOLVE IN THE MOLDS, AND NOT TO DEPEND ON THE PEOPLE THAT HAVE PURCHASED THE AIRPLANE TRY TO SOLVE BY CHANGING RUDDER ETC. COMPOSITE ARF NEED TO STEP UP!!!!!!
