Dear Wayne ;
G'day from sunny but cold OZ !

I'm just about to get 541R back in the air ......... with a borrowed "time-ex" prop.....74" X 48"
(not the greatest numbers...but it'll get me back in the air until I can carve a wooden prop up !)

You might remember, some time back I showed the guys my "redesigned / improved" flap handle
which I made as a "TEE" handle that was more comfortable to the hand & shoulder...and you pull
DOWN to get "down flap "......(which I thought made a whole lot more sense than Murphy's original
setup)....(mind you, I DO realise why Murphy did it their way...simplicity of design / cost etc, etc)

BUT..........

The forces needed to move the flaperons seem quite high...even in flight , where I thought the
vacuum on top of the wing would have helped take some of the weight off the control lever.

I read some time back that you made a floor mounted lever system to move the flaperons..
and also help get rid of some of the slack / slop witht the teleflex cable setup.

Do you have any pic's / drawings of your setup to look at ?....I'd really like to see them !

Many Thanks
(and thanks for all your advice in other matters past !)

Hi folks

I built the flap handle as per the manual. The cut off bolt would come out
of the drilled holes in te flap bracket sometimes so I drilled a 1/4" hole
in the flap handle just below he curve in the flap bracket. Put a 3/8" x 1
1/4" spring on a bolt, inserted in hole, put a washer and nut on the bolt on
the right side of the flap bracket. Now you push the end of the bolt, ease
the cut off bolt out of the hole in the flap bracket, move it ot where you
want it, push handle to insert bolt at correct flap setting, then release
thumb off of bolt end with spring on it. This now pulls the flap handle
toward the flap bracket keeping pressure on it so that it doesn't pop out of
the hole. Wish I had a digital camera. I'm going to try this out and will
let you know how it works.Flew up to Red Deer this weekend to have my
mechanic give the engine a 100 hr. insp. All is well.

Happy flying
