Ralph,   When I started my project back in 2001 (I believe that's correct) I promised myself I was going to set build time records in the Lancair community.   Well... I was right!   Just now in the way I intended.   You have a beautiful airplane there!  Hope to see you at a flyin someday.... Soon.   But something I've learned during the past 12 years.... 'soon' in airplane building is apparently a relative term.   Very best wishes, Joe Trepicone.

Hi Group,  I’ve checked my aileron travel distance after balancing them and discovered I did not have enough travel distance downward (only about 17 degrees and not the required 20 degrees) however I have plenty in the upward direction.  The interference was coming from the lead counter weight itself hitting the top wing, inside wing skin.  (the problem seems slightly worse on the Pilot side than the copilot side)   I used the Lancair cantilevered counter weights that screw to the top of the aileron flange and not the older style that bond to the underside of the flange.  After shaving away enough weight to provide the proper downward aileron I need to add more weight…. About 30% more I’m estimating.  The weight installation instructions say to bevel the edge as required.  I had to do more than just bevel the edge. 

 

I’m going to have to add the older style weight to supplement the cantilevered weight.  Has anyone else had this problem?  I can’t imagine that moving the weight forward or aft would make much difference but maybe there’s an optimum location I haven’t found.  Any thoughts would be appreciated.
