Drat... Bigger problems than I expected. The axle is completely shot and the gear needs a fair bit of work on it.
I gather it's fixable but is a big job requiring some new parts to be made.
If anybody knows of any landing gear for a D31A that is looking for a home - perhaps from an abandoned aircraft or unfinished project - please PM me.
I've also seen pictures of Turbulents with sprung landing gear. If anybody knows anything about tried and tested mods - in the UK or abroad - I'd be interested to hear.
