Shoot Greg. Poke around the forums for parts. I have had really good luck on these GP models finding used and nos parts.
Agreed. The yellow/black is is the best visable choices period!
The OS FR300 is a 49 cc motor. It is equivalent to a 30 cc single. Heavy at 6 pounds without a ring. Flys the 12.5 pound airframe with good authority with a 20/10. Enough clearance to land well without prop strikes. Gotta grease it in being so heavy though. . Easy to tear the gear off.(don't ask how I know that lol) I fly the gp super Stearman with a Saito R5 too. Same set up otherwise. The Saito is a fifty cc.6.5 pounds with a ring. Great everyday flyers.
Not bad on fuel either. Love the sound!
​​​​​​​ Your Waco sounds VERY nice in your dad's video. Really pretty in the air!
