feihu-RCU,

The plane weighs 10 lbs. The sweep angle is hard to tell but only the trailing edge is "swept"The leading edge is straight...The root is 15-3/4 and the tip is 8-3/4. So, the sweep is the difference between 15-3/4 and 8-3/4 over a 32-5/8" span of each trailing edge on each wing....correct? By the way, the weather finally cleared up here in the Bay area, I had the plane out and looked over by some of the "experts",at the club and then.. I did maiden the plane today..but I had a dead stick after some minor trim adjustments. The plane flew for around 1 minute and then dead stick landed into the tall tuley's. After a swamp walk, I found her resting on a soft green clearing. Only small amount of mud on a wingtip, NO DAMAGE!!! So I am ready for another try. THANK-YOU for any input you can give. I Appreciate it!! ;-) Raynman.
