Graham,
Have just been rereading my e-mails about undercarriage setups and am now
really seriously thinking about a more conventional undercarriage for my
beast. I think a taildragger is what I really want. What do you mean by this?:
"The only downside is the rods cost a bomb and do rather loosen the
fillings off piste."
Better to ask, and then know, rather than remain ignorant (even if you do
have to wipe the egg off your face from time to time :-))
