My Feedback: (19)
I wish I had read a simple discussion like this many years ago when I first got into RC. It would have saved me quite a bit of grief wondering why some of my planes behaved so strangely. Good sources of information and theory were not so readily available in those days. I thought speedracer's comments about LE shape were timely as way too many planes get built with very blunt root LE and sharp tip LE.

Thank you guys😊 I went ahead and added som balsa to the inner part of the LE to get it to match the thickness of the wing. However when I set
the LE up against the wing it just looks wrong when it comes to being able to sand the front of it to the correct radius on the inner thicker part of the wing. Maybe im overthinking it. I'll drop a photo of the issue.

As suggested, use care not to sand the tip LE sharper then the root. Also make certain the radius is perfectly symmetrical. If one side is slightly different it will show up as needing some aileron trim and will always favor dropping the same tip during stall.

After you complete your text for your post, make sure your cursor is 1 or 2 lines below and after the text. Your pictures will then attach after the text.
If if you happen to leave your cursor within your text, as when you review it, your pictures will post there. I’ve had that problem and finally figured it out.
and yep, razor plane and sanding.

Thanx for all your input guys. 😊 There are many things that so far just dont make sense to me with this kit. Just look at the picture. The trailing edge has been sanded down to match the curvature of the wing but when i lay the ailerons on to the wing there is a huge difference in thickness. I just dont get it😣 this is my first core wing kit and i have never experienced this with my previous rib winges.

Thanx for all your input guys. I went ahead with the kit and I have made some progress. I will leave my worries about the LE ant TE for later. Made a mistake when drilling the blocks for the wing nuts. The manuals says to drill them with the wing on, at an angle so that the bolts will sit flush with the wing. I didnt do this and had to rectify it by doing this....

In my opinion, if you really like the Titebond, you should give Sig Bond a try. It is the same type of glue, but sands so much easier than Titebond. I use it on all wood projects now, whether it's a model airplane to a cabinet project. Very good stuff and I like to support Sig.
