I was flying the 145 at Dalton this year when one of the pulleys for the raised tail melted and I crashed the machine. At first I thought it was trashed but after looking at the damage I think I will repair it. The majority of the damage was to the tail boom and the horizonal stab. After talking to RC Aerodyne I think I will try one of there new angled gearboxes and shaft drive systems. I have had both belt and cable drive systems fail and really dont care to try them again. Here are a couple of picts of the tail and stab before the repairs.

Put a layer of fiberglass inside have one more to go then a little filler and its done. The stab. is next. Will have to get creative with it. It had the most damage. And yes the Doc could fix it blindfolded and with one hand behind his back. lol

sorry for that happened,it fixable, just use CA glue all pieces together before fiber glass inside the crack area. I am building unpainted EC145 like yours but now I am scare that happen to mine so we may try scale Align short tail torque tube with angled transmission , I hope it will work with some modification. Align scale helicopters has quality control , the other may have not.

Well I hot glued the bottom of the stab to some foam to hold everthing in place while the fiberglass set also put a piece of old carbon tr drive shaft in each side as a spar and a place to run the wires for nav lights. Next I will glass the top piece then put the two togeather. Will try to post a link to the video that Emile shot of the last flight, was not bad till he dropped the camera and ran. lol.Donnie's EC145 accident.AVI

Donnie,

Looks like the repair is going well. It was a shame to see this go in at Dalton.

Thanks Butch. After letting it sit for a few weeks I took another look at the fuselage and decided it was worth fixing. The head and blades had the most damage, looks like the head is a complete loss. Should have the parts for the angled gearbox in a couple weeks then see what it will take to install in this fuse.

yea thats coming olong nicely! surprisingly most crashes like that only look totalled but firberglass is fairly easy to repair inmost cases. over the years i have done many and shared some of the repairs here. only the amount of work involved makes or breaks the desicion to rebuild. like you did Donnie, letting it sit while you recover from the crash shock will show that the repairs are actually not difficult.
great job and thanks for posting the build so others can see that crashed scalers can come back from the dead too

Yep my Cobra went in @ IRCHA and I have it just about ready to go again.. I had it flying the next day at Muncie but the fiberglass fixes took a while longer... Like the Phoenix..she will rise again..

update on the repairs

got the horizontal stab and the boom glassed and a layer of filler on and sanded. A little more filler for the low spots and then some primer. I started on the fuselage last night, it was not as bad as the tail.
