I figured wing area from measuring the wing. The trailing edge of the upper wing may have some extra area from plan but I'm not going to sand it all away or thin it to a knife edge. As another post said I will extend the ailerons slightly on the lower wing for more authority. Looks like I will use (2) 44oz/in mini servos in wing because thats what I have left in inventory.
I am using an tubular aluminum header and macs tuned pipe on mine, not a cast muffler. The fuse is so narrow and it fits there so well and It would just set on my shelf......so who cares what it weighs.
I have several ball bearing .40s that weigh in at 9.6 oz. The instructions recommend .45. The webra .50 is smaller and lighter than my KB screamin .48s and with the tuned pipe at least comparable power. I normally build floaters, this time I want vertical.
I have eight or more planes completed this year waiting for covering. Some fun flys, some profile war birds, a scale sukhoi, and a couple of powered gliders. This bipe is just something different.
