Howard, I didn't have any problem with the covering on my AT6. I used a small trim iron to seal the edges and then went around them with thin CA and they are fine. I used thinned epoxy on the firewall to fuel proof it. The covering is a good match to Ultracote as you noted. I used that to make a small repair to one wing tip. I will say that it holds up very well in the hot sun.

The gear work very well and if you set up the servo properly, no binding or excessive load is found. I honestly think more load is on the ailerons than the gear servo. The struts are short and the tires are light so it isn't much to lift. I have an 1800 MAH in mine and it has proved to be more than enough for a day of flying.

I went with a different pilot and painted it with acrylics. I screwed the canopy on because I plan to open it back up this winter and give the plane more detail in that area.

BTW, the installed split flaps work well also. Mine were just a tad off so that the left side didn't close dead tight. This is a factory installed set-up and not an easy thing to change. I wondered about any effect this might have at speed, but it proved to be no issue, but this is something else I will look at this winter.
