Space Walker "ARF" what engine??
Believe it or not the gear I had came in an old Ace 4-120 kit about 10 years ago. I put a Q42 in the plane so had to jack her up a bit for prop clearance. Aeroglass I believe makes FG gear that would fit. It is well worth the effort because the SW loves to float and it is very hard to make "soft" landings all the time.
