OK, I think after three flights it is about dialed in. The only thing that is lacking is enough braking power. The ones supplied are discs with a sand-paper like surface. I need to see if these can...

I installed the rubber baby buggy bumpers on the down elevator side. I used sticky rubber feet on square balsa posts. But I also glued them in place around the edges. When the epoxy dries enough I...

I ended up using a servo that was 50% stronger for the small nose door and made sure I had 100% mechanical advantage with the door fully open. It worked fine on the second flight yesterday.

FYI, yes the airfoil is as you say it should be. It is the only way you can install the elevators. I thought it was odd but having seen you show this and it being the only way they fit into place I...

Taxi Test

Today I was able to go to the field. If all went well I was going to fly the maiden.
