Default RE: KMP Beechcraft Bonanza's!

Performed test flight yesterday afternoon on Bonanza that had been electrified. Aircraft was basically stock except for modifications for the mounting of an 80 by 85 mm Turnigy 170 KV motor and additional support for battery mounting inside vehicle. Vehicle was controlled by a DX-7 Spektrum full up. All servos were Hitec 65's metal gear type. ESC was also Turnigy 100 amp HV and power was 10 cells Lipos (Rhino) in a 4/4/2 series configuration. Prop was a 19/10 three bladed carbon fiber hollow prop I got second hand from a friend by Biela and worked great.

Taxied to end of our grass 550 foot field and turned into a 6 to 8 knot wind with a 40 degree crosswind component. Initiated takeoff with gradual throttle increase to 60 percent then increased throttle as aircraft reached R1 or rotation speed. Pulled about 1/4 stick and held until nose rotated and increased throttle to 100 percent for climbout. Continued climb to altitude trimming as I went. A few clicks of up and right and headed down wind hands off at about 75 percent power. Gear was retracted as I flew the pattern to get the feel of the new ship. Next downwind I started rolling onto center line and dropped the hammer, hit the threshold of the runway at about 95 mph or so and she was rock solid even in the crosswind with very little lateral movement. Very solid with excellent control harmony on the tail. Rolls were almost axle in nature with point rolls not being any problem. Loops were big and took up the whole sky, tracking was excellent as well. No spins attemped at this time. Don't see a need at this time. After three or four passes up and down the runway set up downwind for a dirty pass to get the feel for a landing. Dirty pass with both gear down and flaps at 20 degrees proved a no brainer. Cleaned up the aircraft and went back to pattern altitude for a full stop landing. Downwind dropped gear and put the flaps at 20 degrees and started a gradual powered decent to landing. Rolled base and dropped flaps to 40 degrees with no pitch change noted. Rolled a very gentle final turn and applied power to compensate for drag. Noticed a little tail wiggle on long final but no drift with the left wind slightly down and a little right rudder being held. Touchdown was nose high on the first third of runway. Runout was great until the nose fell through and then the nose strut seperated the vehicle cleaning the gear doors off and cracking the dang 90 dollar prop. Lynn had failed to fully secure the nose strut to the stud. Oh well, what the hell it's only money and its supposed to be fun. From my standpoint as the pilot for this flight it was a hoot. I have a few hours in the full size bird and Lynn had hundreds so we considered it a successful day even though we bent the prop and will have to add the dang doors back. Next week though pictures I hope. We forgot the camera. It was a hoot and the aircraft was a dream to fly. At 19 pounds its rock solid and the paper towels and cleaner were left at the house. ed
