Default RE: 130 Flaps

There must have been a glitch last night in rcu.

Actually, I purosely build up a lot of ground speed prior to lift off. (a typical saftey margine for multi engine aircraft in case a flame out occurs) I know it will lift off a lot sooner and at a lower takeoff speed because on one of the taxi tests it went airborne to an altitude of 6 feet and I flew it for about 200 feet down the runway and landed. I did'nt want to get airborn but I had not much fuel left to actually fly her around. (I was spending about a half hour in tuning/synch'ing the engines).

Also, Steve has a good eye. The take off position flaps are 15 degrees, which I can putt putt around at about 3/8 throttle. With no flaps the plane does fly fast and will hold altitude at 50% throttle. At 49% throt. she will slowly lose altitude. Also my 4 bladed props are fine pitched so they are more efficient in a 4 bladed configuration. But with 15 deg. of flaps and some ground speed behind it and the engines turning at 10,500 RPM's she'll easily take off at a steep angle. The power of these OS .32 SX's and my 9x5 props are more than enough to handle this 22 lb bird (dry) Take off weight is at 23 1/2 lbs fulley fueled.

Landings: She slows down very nicley at a scale high angle of attack with no bad tendencies. Probably due to the -2 degrees of washout in both wing tips.
