Airplane 575 Limit based on an older, standard tail version, of the tiny Germania Limit slope soarer. It was enlarged to a 575mm span from an origonal 455mm.
The construction uses a depron skinned wing with an internal spar.
No ribs are used. The rear 1/2" of the wing skins are glued together with POR adhesive, the two skins are glued to the spar which is at the 1/3rd chord position. The depron skins at the front of the wing are pulled together and taped. with care you get a symetrical wing which is more than strong enough.
The box Fuz is built of 1/16" balsa or 3mm depron. just like you would build any other fuz.Tail and tailplane are from 3mm deprom.
Does size really matter? Here is the first run of 2020 and a comparison and test of the Hobby Plus CR-18 (1/18th Scale) and the Hobby Plus CR-24 (1/24th Scale)
