I thought you guys might be interested in my latest project to be completed. "Sparky" is a Harry Hundleby design originally published in Sep 1951 Aeromodeller for single channel R/C. It was described as having a breathtaking performance and was intended for single channel aerobatics. I started this project a long time ago for diesel power but when I got around to finishing it I decided to go for brushless electric. Construction is traditional as per the original and fuselage is covered with tissue over balsa sheet with wings and tail covered in nylon. Control is rudder and elevator, motor is a Scorpion 2215-18 and LiPo is a 3S 2200mAh.
I recently carried out the test flight. Full power climb was rapid, very little power required to just cruise, more power and loops and rudder rolls were good fun. I landed after 14 mins and a recharge took 931mAh, battery is 2200mAh so could have stayed up for a fair bit longer. A nice and unusual addition to my vintage R/C model collection.
