This is my Depron Extra 300 electric park flyer built from 6 mm depron. The plan is from RCPowers which is a free plan.
Power is a TowerPro 2409 1000KV brushless turning a 10×3.8 slow fly prop. The battery is a 1300mAH 3 cell lipo with an 18Amp speed controller.
Maiden flight was a complete success with bags of power, even managed a bit of prop hanging. Best fun you can have with a sheet of depron.
Colour scheme inspired by my wife who once had a dress like this bought for her by her mother and had to wear it!! Poor girl, anyway it did the trick and I married not long after.
