RE: seagull extra 300s
I have several flights on mine. It does like speed on landing, TT 61 with Pitts muffler.
I would like to change out the gear mounting bolts to nylon, but the blind nuts would have be pulled out to do that. Once you knock the gear out on a dead stick in the weeds its a chore to keep it epoxied in. Hopeflly the nylons would shear off.
