Hello everybody, this is my first build thread, but not my first build.
I took some pictures and will post them here, together with my remarks.
Cliff C's plan is very clear, but I might have misread some parts, and some
details like the CoG are missing, so I hope I can get some input from you.
The short kit is very well cut from top notch balsa and ply, but I had to recut
some parts (several times as I made plenty mistakes)
If I would build the wing a second time I would have built the spar classically.
Cliff Evans cut the jig and added it, and I donot think one can build the fuzz without the jig!
Some dimensions of the wood (balsa and spruce) were modified as these sizes
were not available in France
Instead of 4.5 mm square hard balsa sticks I used 4 mm Samba (Obeche) and the
6x4.5 mm spruce keel was made from two 5x3 mm spruce sticks glued together

Re: Cliff Charlesworth Ka3 from LCS
The jig supplied by Cliff Evans, I had to modify some parts to
account for the skid, which explains the "amateur" Iook, and
added the tail post as it helps positioning the keel, I downsized
the pictures 4 times to keep the file-size down,
please let me know if you prefer larger pictures
