X-flight twin 70mm EDF Rafale

Very nice looking rafale with modified single 70mm EDF. Hoffman Magnetic at 4s x 70A ( limit of my lipo) ~ 1,000W. Certainly, at 1,400W it can fly even more ballistic!

My DIY is simple to make and cheap. What you need is

1) 3mm collars x 2

2) M3 screw and washer

3) A rectangular piece of fiber glass.

4) rubber band or propeller O-ring

The tension is set to ~2-2.5G . My rafale weights 1.4kg and the tension is set to ~ 3kg. The landing gear is all intact , even with hard landings.
