I rebuilt a Rans S4 and am keeping it as a taildragger for sure, love it. If weather holds out and my IVO prop gets here shortly it will see the air. Have had it up and down the runway to check things out and of course learn not to ground loop, lol. It has a dual carb 503 points engine. Prop that I got with the motor was too big. Will get off the ground but doesn't have any climb to it. Lugging and you all know where that will get you. I will post weight on it soon. It's electric start but only a tiny tack and airspeed. 5gal behind seat. Don't plan on cross country with it anyways. Teddy
