I feel your pain! :scream:
I, too, can easily use the rear brake to adjust in the air...but when things go really bad, I have trouble using it. At that point, I doubt it will help much, anyway.
BTW, I would keep it a 2 step process of clutch first then brake. If you do both at the same time, I think you'll end up doing some dead-stick landings. (and it gets real quiet flying through the air with no motor running :o)
For what my spodely opinion is worth, I agree with Jaybird completely.
