RE: CMP BF109F BUILDING THREAD
Flight Report
Equipment:
OS 160 2 cycle engine
Ram on-board glow driver (5000 mah battery)
Spring Air retracts (in stock location)
Zinger 17 x 10 prop
Aluminum spinner
Duralite receiver battery (mounted aft of pilot to balance plane)
Recommended control surface throws, per instructions.
CG - 115mm
First flight:
Ground handling good. Take off uneventful. Tracked straight down the runway. Normal amount of right rudder for tail dragger / warbird. Trim; added several clicks of down trim, two or three clicks of aileron trim. Engine running rich (not completely broken in). Plane is very stable and smooth in flight. Dropped full flaps on final. Did not use spoilers. Flame out on final. Barely cleared fence at the end of the field, plane on the edge of a stall, then stalled 2-3 feet above ground. Dropped flat, took out gear, no other damage.
Reinforced landing gear mounts. (keeping stock location)
Second flight:
Switched prop to APC 16x12 (much better!) Leaned out engine a bit. Plane flying much faster! Several low altitude, high speed passes had fellow club members drooling!! Same set up for landing; full flaps, no spoilers. Kept 3-4 clicks of throttle until over threshold. Came in a little hot. Used full runway to slow down.
Conclusion; This plane is very fun to fly and looks great in the air. P-51's and P-47's look out!!! Take offs and landing require your full attention. (as expected with a tail dragger warbird with narrow gear) I would not move CG forward (of 115mm) unless I re-positioned the gear. (as others have done) Having the CG close to the position of the main wheels could lead to nose overs on take off. [img][/img]
