RE: Elder 20 ,Can you help please?

WARNING. The ELDER 20 as built by the plans is virtually un controllable!!!
The rudder is waaaayyyy toooo small! May I suggest you DOUBLE the size by making it twice as wide as called for on the plans, then add a square as tall as the rudder is wide to the top of the rudder? Then it might turn in a reasonable manner.
Then the forward mounted main gear and tail skid are cute but they won't let it turn on grass and they won't let it go straight on pavement. And the long, long, loonnng moment from the skid to the wheels does nothing but make it bounce like a bunny rabbit on landing.
Turn the main gear around 180 degrees and attach what was the rear mount to the original rear mounting point, then add a new hard wood block under the fuselage lower skin where the front gear strut hits under the wing. This stops the bouncing and still is far enough forward to prevent most noseovers.
The only fix for the tail skid is a tail wheel or a stearable skid.
I flew one of these for 5 years and only had fun on it after I made these mods
