I hadn't heard of thi= s technique before, but it makes sense.  It sounds like a simple way t= o prevent an unfavorable spanwise load distribution and tip stall at really= low speed.
Tapered wings tend to push stall initiat= ion out to the tip.  To counter this, washout can be used to unload th= e tip. My 360 has 2 degrees washout.  Deflecting an aileron = will defeat the effect of washout and will again promote tip stall.  L= owering flaps to the same angle as the aileron throw unloads the tip to the= point where full aileron deflection won't produce a tip stall. <= /span>

Hi All,

T= here isn't a particular reason I don't want to use flaps other than I don't= like the "sinking feeling"...  but I will take a look at Bob's sugges= tion on how to slow that down.   I was also taught the "deflect t= he ailerons and put the flaps down to that point" which I guessed was about= 15 degrees or so.  I see here that its actually 20 degrees....  =
