Default RE: Herr Pitts Special Kit Build Thread

Thanks for this, drobbs. Will reference this when I do my bolt on wing mod work.

Got the lower right side of the wing spar in place. Elevated the left side of the wing with a square piece of sheeting and also used pins to keep it square and level while I build up the right side of the wing.



Ribs and sheeting in place...



To install the spars and assure good coverage of Titebond II I installed the spars first and centered them in the center groove until they set up. To install the ply dihedral braces, you can get them wet with glue on one side and kinda tip them into their place so you don't scrape off the glue when you place it. Also adding a few drops of glue to the middle area where it's gonna be tight helps get good coverage.



I'm not going to install servos in the wings. Would be a very tight squeeze if at all. Instead, I will install two aileron servos in the fuselage to use the torque rods. To connect to the upper ailerons and assure that there is no differential from the angle at which they'll be connected, I'll install arms the length of the aileron material on the bottom of the ailerons as close to the fuselage as I can to minimize torque effect to control the upper ailerons and equidistant from the point of pivot. I added some sheeting to reinforce the area where I will be cutting grooves in the TE sheeting to accomodate the control rods and arms. Should be relatively concealed when sitting on the ground with regards to aesthetics.



Red Xs show where the sheeting was extended/added as part of this mod...



Pretty exciting when you start running low on material from your kit... means you're getting close to being finished. I see a few solid evenings of putty and sanding ahead in the near future.
