This is my twin Speed 400-motor flying wing. It is built from pink foam and packing tape. The construction takes an evening or two and is very uncomplicated. You can get the foam cores and all other things you need from LW-AERO TRADING (phone +46 (0)8 774 66 99, e-mail: lsw@canit.se).
The wing flies fine with one motor also or without motor, i.e. on the slope. Flight time is 4-5 minutes with 8x800AR. Loops from level flight is easy and the roll rate is high
