    Ahh, I bet your absolutely correct John. I replaced my original screws. Im not sure if it was those that have stripped or if its the new Stainless ones I have now. I noticed that these two types of screws are slightly different size so I bet your right. I know that I don't put too much torque on these that I have now so I have been having pretty good luck lately.

    Stainless steel screws/threads fail at a lower torque than steel ones. The thread pitch could be slightly different too, which may explain your problem.

    We have made good progress this month. last half has been slow but feeling good about the progress.

    Finished up the rudder pedals but forgot that I sanded down weld a little under one of the master cylinder brackets. I have some epoxy resin on order so everything needs to back apart again. I also started to work on the tail fairings. The one that attaches to the tail is ready to cut the top and bottoms off for proper size but all ribs are formed and the transitions look good.

    I still have some rubbing on the seat pan. Only on the far left deflection. Anyone have any ideas? I was thinking that during rigging the flight controls and setting the proper limit on the limit screws would help. Maybe the deflection is too much to start with. Seems unlikely though. I should add it only rubs when im sitting in it.

    More than a few members here have added wood blocks under the seats to prevent jammed/impaired flight controls. I had some nice balsa blocks that worked nice without the extra weight. If it's rubbing now imagine what would happen in some turbulence, or if some weight challenged passenger was riding with you! Like me! Lol. A search of TeamKitfox would bring you several solutions.

    Keep up the great work Michael!

    Agree with Brett, you need some blocks under there. Also, that control rod that passes under the seat has a slight bend in it; on mine I increased the bend angle just slightly more to eliminate any interference and also installed a couple of blocks.

    Thanks guys! I think I will try the blocks first! Bending that rod would freak me out! There was pretty good clearance without me in it and seems like good insurance for the possibility of a cracked seat pan!

    Make sure when you do the final control adjustment that this rod ends up with the bend hanging down.

    Thanks! I have heard of that and i made sure it was as far down as it could go and also checked to make sure i had that installed the correct way.
