A lot of the old designs are short by today's standard, I'm not sure why? Some of the engines back then where a bit on the vibratory side so maybe they had to shorten the heavy fuse a bit to keep the weight down? Maybe they were influenced by full sized planes? Who knows, but they didn't seem to start lengthening planes until the mid 80's.
The plane won't fly "wrong" with extra length and if you build it light you may not have to add much extra to the nose as the CG will most like have to move further back too unless you make the stab area smaller.
No I don't "want to fly a Hammer .40". I want to fly a classic pattern/aerobatic type aircraft not a sport type aircraft. Trying to find one this size that is in kit form and that you aren't being ripped off by a greedy seller is a task. The Hammer 40 looks like a good one to do some toying around with. There is a single former between the wing and the stab and the fuse is solid so it should be sturdy enough to handle an extra 3 inches on both sides of that former. Only a few pieces need to be modified from the drawing and this is a short kit so I have to cut them anyway.
