Well got one test flight. As usual something came lose during flight. This time the perry carb on the front of my OS91 lost both screws. For some reason is ran great until I throttle back for the first landing. Then it is was dead stick and too far from the runway. A little ding on the leading edge and another reminder to make a shorter first flight, land and check to see if everything is still tight.

Anyway, got about 10 mintues; but as soon as the model broke ground you could tell it is a keeper. Flies straight for no coupling noticed yet. CG at 7.25 inches and it seems perfect to me. I must have come out more tail heavy than yours, as I have to put the battery at the firewall to get the CG this far forward. So I could easily put a heavier engine up front and shift the battery back. Put it seems to have nearly unlimited vertical on the APC13X8 and a half and half mix of cool power 15% and Magnum YS blend. I run a perry carb, until it tried to depart the engine. Just the fuel tubing and throttle clevis holding the carb in place when I got the plan back.
