My 35-1/2" WS Yak all Foam electric plane, tail dragger, has a very weak main landing gear. The gear keeps bending and eventually it broke. I replaced it with a torsion bar type landing gear that is working out perfectly. The gear is made from 3/32" diameter music wire as shown on the attached two photos. The distance between the two bends that make up the torsion bar is 5-1/4" but I have decided it is too soft, so I am suggesting it be 4-1/4". The gear is anchored by some wood popsicle sticks glued to the foam and then tied with string thru the fuselage.
