Riley Short-Field Take-off

[Red Air Rambo]

I was told by a friend with a Riley Super Skyrocket that Riley would do a 2/3rd's (or 20% depending on model) flap takeoff for short-fields Is anyone familiar with more than a 10% or 1/3rd flap take-off as the POH states? ......I've googled and need some ole school advice.


Thanks,
Brent

Use as much flap as aileron travel for max performance

I've got the Horton STOL and not the Robertson.

That's good, same recipe
Select max travel on the aileron and match the flap angle

Ok...thanks Herb I'll give it a try.

Ok...ready to learn: what's the aerodynamic/aircraft performance science behind this statement. Not doubting it, just asking where this nugget comes from.

Comes from the Robertson STOL training they did many moons ago. Back country flying uses this technique frequently for short T/O procedures
