Hi,
Suggest Springair 400 series with 7/16" Robart legs on the
mains fitted with Intairco brakes (3 1/2"), Intairco noseleg and
2 1/4" nose wheel, just a suggestion but replace the lite ply
nose gear mount side plates with good ply using the originals
as a pattern. The original Graupner gear lasts maye 25-30
flights depending on the surface you fly from ........
