Well Jack, just came back from flying and my buddy had it on his Extra 260 on a DL 50 .. He said it outperformed the other props he had on and the latest was a Menz 20*10 so I am happy with my design..

Hi Doug,
I will try my best, but what they are is like a trim tabs but operate in opposite of the control surfave it is attached to .

with the proper size and proper setup, you can reduce the size of servo/s from this control surface by 85%....

The only problem you can't buy these, you have to build them in as you build or as an after thought, and with today's Arf, no one seems to want to build so you won't see many around ,/

By installing boost tabs, you will be able to reduce the total weight of the airplane .

Less servos, which means smaller batteries, , one servo/control surface, means no matchbox, even rudder can use only one servo with the biggest out there.

so not only will you save on the weight but will save lot of money in the process and not jeapordise the control authorithy nor the safety of the aircraft.

Here is a very good article that you should read for a more indebt information

Hope this helps

Dang that's a bunch of snow! If I lived up there, I'd have to make ski's for my Carden. I wonder if that's ever been done?

Fire up the turbo prop and get melting.

Jack,
Today I made the boost tab structure but didn't cut them loose at this time , easier to sand everything together
