Has anyone out there put an O.S. 70 4 stroke on a Sig Smith Miniplane. If so, was there balance issues?
I watched a Smith Miniplane video on Youtube last nite in which the pilot claims to have been using an OS 70 and 12-6 prop.

So did I. But you will also notice that not one time did he ever have control of the aircraft on take off. I remember he aborted take off at least three times because he could never control the ground looping.
The 70 will fly it, so would a G63. But I wouldn't recommend either.
I also saw a video of the mini with a Magnum .52. It had plenty of power.
At higher altitudes I would probably be recomending the .70. But even in Denver, the Saito .56 was perfect.
Regarding the fuse joints:
This is where it is a builder's kit for sure. I would lay the 1/4 square stick on top of the plan, use a straight edge and mark the angle on the stick. Then I would either cut it with my exacto knife, or better yet if you have one, use a disk sander with the table at 90 degrees to ensure a perfect angle.
I enjoy the mini build emensly. Now I'm going to have to build another! [sm=shades_smile.gif]
