What's so wrong with using the wooden ramp? I use this solution for my
ASW15/Avionic setup and in my club we also have ASW19/Komet,
ASW20/Komet and ASW20/Cobra combinations all using a small wooden ramp.
The Waibel designs (except the ASW12) all seem to combine a fairly low
landing gear with a drooped front fuselage which makes it hard to get
the dolly low enough to clear. I think it's a lot easier just to keep
things the way they are.
