@ hezik: I fully agree that a programmable brake is not a "miracle" thing but definitively can help. Can you also please explain more in detail movement of the ailerons on the bipe in order to create a braking effect. I am also flying warmliners so am quite familiar with "crow" brakes, is it something similar? I guess you have seen the thread about Wind S Pro and the photo where the wings of Wind 110 and S Pro are compared and how much thinner are the wings of the S Pro. I am looking forward to read some flight reports, lets not forget that Seba was using counter-rotating props on that thing, something not everyone has.</p>

As far as I know, from unconfirmed sources, magnets on most motors are good up to 80 Celsius, so not that much on a hot sunny day. On Scorpion motors and some Kontronik motors the magnets are made to resist up to 200 Celsius. I have recently ordered for my Kelly project a Scorpion HK 4035-400 (same size as Hacker 50S series) which should be able to produce 3400W continuous, let's hope its true coz I will really push it to the max!</p>
