This is Bambina, which I built from a free plan included in the RCM&E special edition last September. Its a 31″ aerobatic powered by a 4-max PPOM-2321-2050 motor, 6 x 4 prop and a 25C 3S 350 mAh battery using a 15 A ESC. This is the first model I have scratch built that has a fully built-up wing. I don’t have proper building board so I found it difficult a times but got there in the end.<\/p>\n\n\n\n

I made the canopy by shrinking part of a lemonade bottle over a balsa plug using a heat gun and then painted the inside surface black.<\/p>\n\n\n\n

I took the option not to fit an UC but fitted a hand hold\/skid to the underside of the fuz; it has sandpaper on the skid sides to provide good launching grip. The servo\/linkage aileron covers are made from modified plastic lollipop moulds.<\/p>\n\n\n\n

The covering is Hobbyking film and the red and black trim is Fablon, (purchased from Homebase and far cheaper than Solartrim\/Oratrim).With the help of Paul Morris as a launcher, the maiden flight was on February 6th but the 350 mAh battery proved totally inadequate. At full throttle, I could only keep it barely 3 feet of the ground and after about 20 seconds it just died and belly landed in the long grass of a our patch.
Bench test wattage measurement showed less than 80 per pound maximum and decreasing rapidly. I have now fitted an 850 mAh battery (same as I use in my Super Kinetic), which showed plenty of long lasting power.<\/p>\n\n\n\n

I am now just waiting for good weather to do another test flight.<\/p><\/p>\n\n\n\n
