RE: Ultra Rc Evolution
It flies!
The maiden flight went well; it took 3 clicks left and 1 click up to get it track straight, and it feels fairly light in the air. The OS 160 pulls the plane straight up effortlessly, and other than vertical, very seldom throttle needs to go beyond 60%, which makes the fuel consumption very reasonable.
The CG is right behind the wing tube, and at this position, it only needs very slight push on the down elevator to maintain inverted flight, and it feels about right for now. The rudder is very efficient; it doesn’t need much to KE, and after reducing the throws three times, it still needs more reduction. Down line goes straight and stayed locked in, but since there were some slight breeze, it will be checked again when the condition is better, but it feels pretty good for now.
I only had time to put in four flights today, and it feels better each flight. The landing gear held up so far, and this is with two crosswind landings. The only modification was inserting CF rod into the stock CF tube.
