Time to dig into spars

It's been a busy summer with kids sports, boating and working.  The boats are put away and the time has come to start drilling some holes.  I'm getting ready to start my spars and I have to admit that I'm not looking forward to these, don't know why, just dreading them.  My building buddy Timothy has his done already, so I will be leaning on him for much needed motivation.  Some times,...... ok most of the time I wish I had a pile of money to buy a kit but that's not going to happen. Well, here…See More

UL Service

In August of 2011 I did a UAV job for the ARMY with a new Rotax 914. From the start the engine ran poorly. After long hours of diagnosis it was found that the magnets on the flywheel were not in Rotax speck. Rotax required us to purchase a new flywheel (700.00$) and send the original one in for credit if they determined it to be faulty. The new part fixed the engine.

More Spar Work

This afternoon, I re-cut the spar web doublers for both wing spars and then drilled pilot holes along one side of one spar. Time and light did not permit me to finish the other side. I still need to mark rivet points for the ribs, L-angles, and the spar web doublers.See More
