I am about to start making my tail hinges. On the plans, 13Ga. material is calledout with #8 screws. In the Flying Manual 16Ga. material is called out with3/16" hex bolts (close to #10). Does any one have a comment.I am going to try the Bill Church method to make hinge plates without welding.Scott--------ScottRead this topic online here:http://forums.matronics.com/viewtopic.p ... __________

I have what I consider a bit more traditional Model-A engine in that it has roundpistons and babbit bearings but when I first went to start it, it was extremelytight and after it ran for a bit you could barely pull the prop through.In researching break-in, many spoke of running the engine in for quite a whileon the ground and a couple said about 20-hours minimum. I ran mine at variousRPMs during each session (from 30 to 60 minutes) until I had 22-hours on itand by that time I had tweaked all the adjustments and when I first flew I feltvery confident in the engine. It may have been over-kill, but Im happy I didit that way.Read this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Re: Hinge Tail Feathers
