Posted: Sat Feb 25, 2006 6:22 pm Post subject: Flaperon Hanger Bracket Installation

List:



I am getting ready to drill the holes to attach the flaperon hanger brackets

to the ribs on a Model 4 - 1050.  The manual calls for a space of 0.25" from

the trailing edge to the edge of the top bracket bolt hole.  The problem is

that when I slide them onto the rib without bending them I get something

more like a 1/2" gap.  So my question is, do I install them with the 1/2"

gap, or do I force them further up the ribs by flexing (bending) them to get

the 1/4" gap?  Is there a problem with having them mounted further back from

the trailing edge than the manual calls for?  How much space do other's have

between the training edge and the bracket?



Thanks for any and all advice.

Bill I am right behind you and hope to be mounting my flaperons in the next 

week or two.  I will refrain from suggesting mounting them farther back than 

designed for three reasons.  1 make sure you are mounting to enough rib.  2 

make sure you can align with bearing center at turtle deck. 3 I might get 

flamed for suggesting a shortcut.  Hopefully someone else has been down this 

road before and can offer a good solution.

    I am rebuilding a wing that was destroyed by the former non-builder.  

One of the things he did wrong was to force a dull bit while drilling the 

flaperon attachment holes in the wing.  This pushed some of the aluminum 

reinforcement plates away from the rib so that they were not captured by the 

rivets when assembled.  I plan on using a new bit in a high speed drill to 

do these holes.

Bill and Ron,



I just checked my hangar brackets and there is at least 1/2" between the 

trailing edge and the point where the top bracket and the bottom bracket 

meet just before the rivet.  Actually it's more like 5/8" - I went out and 

measured  and the latter is what I have on my airplane.  I fly a Mod 

IV-1200.  The fit gets even tighter after covering - two layers of fabric 

and a layer of finishing tape on both sides of the wing, at least on the aft 

most inch or so.



Regarding the aluminum backing plates and the drilling process.  Put a 

spring clamp on both sides of the intended hole.  I thought I was pretty 

careful about the backing plate gluing process, but I had more than one 

separate from the capstrip.

Hi Bill,



I had to use some force and clamps to put mine in

position, but I went by the plans here.  It was worth

it.  Just be careful not to strain the rivets in the

flapperon brackets too much.  I think I bent all the

upper mounts a little to keep the strain down and make

them fit better.  It only takes a little verticle

change to make them go forward that extra 1/4 inch. 

Take your time and it will come out right.
