No.. it hasn't flown yet. I did "try" once. It was right on the deadline of the 1st speed contest.. and I was having multiple problems. The engine didn't want to run consistently.. and was a Bear to start. Add to that; nose-over after nose-over.. and I was beginning to think it was sign "not to fly it" before going through the engine again. I was also using a pin-release (stooge) that placed the tail-wheel 1/2" above the rough asphalt that I was flying from. It wouldn't move 2 feet without nosing-over. I'm confident that it will fly with a good engine run. Wingspan is 17.0" and it's area is 70.125" square inches. The root-chord is almost 6 inches with an average chord of 4.125". Weight dry is 7.20 ounces. Fuel tank capacity is 6.15cc's. The engine has a Tee Dee .049 cyl./piston, std. glow-head, stock case/crank, Killer Bee backplate and a Cox 5 x 4 black prop. The next attempt at a flight will be over grass.. and I will lay-out some lg. sheets of corrugated cardboard for a runway. I also have some APC 4.75 x 4 props that should really increase performance.. as long as I can get them bushed/balanced properly. I was too nervous to run them previously.

Thanks for the compliment!

I'm confused about this "Lil bear" "Rare bear" thing. Didn't Kim or Mark Boeson (or both) model one once and post about it here? I love it and would like to build one. Nicest looking model that I have seen. Was this used as inspiration? Wonderful job on it roddie.
