I met with Larry & Andy on Friday for test flights. Too windy but got a couple of pictures.

The first is our intrepid builder/tester Andy holding the test model. The second is a shot of how Andy designed a battery holder to fit under the wing.  The holder is very simple yet it works perfectly. Please note the small "X" on either side of the battery. This mark the C/G on the model. Andy moved the battery back and forth until he got a perfect balance. He then marked the location with a line on the battery. All he has to do is to match up the line with the C/G marks and he has a perfect battery location when he replaces the battery. In my opinion this shows how creative Andy is. The system is very simple yet it works perfectly!

Yes Andy is one of the good guys and very ingenious.

You may have noticed that I have kept my nose out of this discussion.  But I must admit I was quite pleased with yesterdays test flight, right off the board I was able to do everything in the OTS pattern without a hitch.  One weird thing to report, the battery hold down popped off the plane when I was removing the battery after the flight.  This morning when I started the repair I notice something I had never seen before, the epoxy holding tie downs had never completely hardened.  It was 5 minute epoxy that I had used many times but for some reason it only hardened completely around the edges.  I think it might have something to do with applying the epoxy over the doped covering material before the dope had enough time to completely dry.  Today I removed all the covering material where the hold downs are attached and then saturated the balsa with thin CA.  I removed all the epoxy from the tie downs and glued them with 30 minute epoxy.  I have used this method for tie downs and several of my electric planes and never had this problem.  I am just thankful it didn't happen while flying. 

Finally thanks for all the nice comments I think this plane will be a lot of fun to have, lets face it we all at one time or another had a Ringmaster and this plane flies like a Ringmaster.
