Does anyone have some pics of how you fixed the problem of the laser cut elevator LE being too thin? The problem has been noted before in the kit manufacturers forum but there were no pics showing a fix. I plan to simply build up the whole lot with spare 1/16 sheeting but if someone has a better idea I appreciate your view. Perhaps I could just sand down the stab TE?

Andrew,
I ran into the same problem and saw your post in the manufacturers forum. I took some lightweight balsa and just built up the edges and then sanded them to shape. Like yourself, I didn't notice the problem until they were built so swapping out the parts for new ones was a problem. Also, keep in mind that you will gain a little thickness when you cover them depending on what you use. I didn't see this coming so early in the build or I would have caught it. Just wait because it gets better. The rudder has the opposite problem. The rudder is thicker than the trailing edge of the fin. There are also problems with the parts around the cockpit area. The cockpit floor and one of the formers is not wide enough so you have to build that area up before you sheet it or you get a big dip in that area.
Let me know if you need any more help.

Here is where I am currently at with the fuse. The sheeting wasn't flush with the firewall yet so ignore the fact that the cowl isn't square. I just taped it there for the picture. I have a full write up on my build over at this link: http://www.rcscalebuilder.com/forum/...et=last#174878

i was unaware of the problem before building as well. ignorance is bliss? maybe, but i ended up adding a hinge gap which pretty much takes care of the excess gap between elevators and stab t.e.

Thanks for responding. Fixing by cladding the LE and blocks with scrap sheeting was easier than I thought it would be and really only cost me an hour.
Your fuse looks great Rusty!
Also, Tim, I followed your build and the result was great. It's what convinced me to go with this kit!
Hopefully Bax will have TF fix the laser cut program before they run their next batch! A bit easier than retooling dies! While I think of it, they should also profile the elevator LE to the tip shape perhaps a bit oversize (like the rudder) as this would help in shaping the blocks to the correct tip shape. (My shaping skills ar a bit poor, I'm afraid, and I need all the help I can get in this regard!) If I'd thought of it first I would have done it myself.
