then you'll know what all to look for when you prep it out. I'd never heard of you and a single blade before......... it's like flying an MR, but,,,, there is so many fail points on a SRH, especialy used. Tail drives are a big place to spend time, balance everything, check all the shafts.
IF you guys can work a deal, it'd be fun to play with. I put a JR ergo .46 to rest a year ago. The model had been out of production for 6 years and finally bought out all the crash parts i could find. Shafts are the hardest, and sometimes other parts get you close enough to mod a part in, but sometimes that's it. It'd be worth looking to see what you can buy before you fly it
Good luck and happy new year
ps, if ya need a tail servo, got a great one Chris recomended i'll make ya a deal on,,,,, hahaha
