Having just signed up last night, I'm not certain that I am posting this question properly, and would appreciate any pointers as to where I should request future inquiries. I am building a 601XL. Finished all of the tail,ailerons,flaps and now working on the right wing. I was looking for any comments about the 1 1/2 inch hole cut out of the rear channel for the aileron rod. The plans call for the center of the hole to be 20 mm up from the flange. The radius is 19 mm. Due to the curve taking up about 2 mm, this would cause the hole to cut down into the curve of the flange about 1 mm. The plant in Mexico, Mo. said that that was OK, but the picture in my photo guide does not appear to show the hole cut down into the flange. Wondered if there is plenty of room to raise this hole up a mil or so or should I cut it into the curve? Thanks. John  johnrich(at)everestkc.net

	Go ahead and cut the hole just above the curve of the bend. You

will still have plenty of clearance for the control rod when it is

finished.

I was recently asking myself the same question. Andy Elliott recently 

speculated on this list whether the hole resulted in a weak spot in the 

rear spar. See:



http://members.cox.net/n601ge/drawings/rearspar.html



I looked at the wing of a friend's QBK (see attached photo). The hole (done 

by the QBK factory) was right at the bend to the flange. But, it looked to 

me that it could have been ~5-mm higher and still had good clearance for 

the control rod. That said, the aileron was not yet mounted on the wing, 

and it wasn't  under load, so I could be wrong about that.



I decided to move my hole up ~5-mm, but when I cut the hole it ended up 

only 3-mm higher than plans. Hopefully that will work fine.

I believe that the hole as specified in the plans is larger than it need be.  I would suggest going a smaller and then clecoing the aileron in place and connecting it to the bellcrank with the pushrod.  Run the aileron to it's limits and you will see exactly what you need.  You can always make it a little larger once you've seen the fit.



There is plenty of support around this area but why remove more metal than necessary?  That said, be sure to allow enough wiggle room so there is no chance of binding in the hole.  I've attached a pix of what I found would work for me... your experience may differ.

As have several other scratch builders, I spliced my rear spars to facilitate bending shorter pieces and installed a doubler to join the halves. .The splice doubler also serves to strengthen the area around the aileron linkage hole. I don't know why you couldn't rivet a doubler of six inches or so to beef up a one piece spar in that area. And no, I'm not an Astronaut, Engineer, Airplane designer, or professional bowler, but I did stay at a Holiday Inn Express one night.
