Malin , I read your post and it sounded so familiar. I too started out wanting this ARF and then heard so many things about it I decided against it. Then I read most of the post on RCU and decided to go with it. Never had a complaint. Only problem was that I crashed due to my own stupidity. Long story not worth going into. Anyways, I bought another one and will assemble after I finish the project I am am on. I do plan on using Robart pin hinges in the next one. I didn't have any problems with the standard stock hinges, but have read enough to believe a change is warranted. Also, the new version stock mods worked well. Only real change I made was to beef up the firewall. I modified the stock spinner so that it works more like a Dave Brown or True Turn adaptor with a threaded hole in the the prop bolt and then a long sockect head screw to secure it. Can't help you on the Moki. Good luck and good of Bipes.
