Hi all tack a look at this, it may interest some of you guys that lick to fly something different, I spoke to Simon about it at lased weeks FPV meeting and sead that I would uplod a link, with new technologies like the FY90Q to steady the flight, it could make an interesting FPV platform, one motor a prop and 4 flaps, ther is qwit a lot of info about it, if you googol Coanda effect.

That's brilliant, :) I can't what to see the results, I have a FY90Q Quadrocopter Stabilisation System, in my bits box I think that would be ideal for stabling the flight, will you be using something similar on yours.

I'm trying to work out how this is different from a normal wing???

Fast moving air over a surface causes low pressure - theair underneith has a higher pressure, so a force is exerted in the direction from high to low - same principle a wing works on...

Oh yes - please forgive if this is an utterly stupid question...  I seem to be having a "stupid" day today...  :-X
