Joco1,

I think the .75 is overkill – it flies well on a .61 – it is a trainer, and if you want more aerobatic performance out of it then you should consider something like the Goldberg Tiger 60 (unless you fly at high altitudes) for the .75. For the .75 I’d stay with a pitch no more than 5”. I fly an Evolution .61 on mine, and right now I’m using an Evolution 12 X 6 glass nylon prop. I fly at ½ throttle and it’s more than fast enough. When I get students back on it I’ll probably slow down some more, or switch to a 12 X 5 or 13 X 5 prop. If you do intent to run the .75, then put triangular stock on both sides of the firewall for reinforcement. I’m not sure what type of speeds you’re looking at with the .75, but I’d definitely epoxy the empennage in place and add triangular stock on either side of the tail just to be safe. For flight training with a 5” or 6” pitch prop I never find a need to go above ½ throttle unless its for take-off or a balked landing.

For my replacement NLG I have to see what the LHS has in stock. I’d like a Fults, but a Dubro will work. Also I prefer the straight gear so I can adjust the length to suite the plane and not get stuck with the nose either too low or too high which could happen with a bend gear (bent meaning the wire is bent 90 deg. to form the axle).

I’ve been looking at what I need to do to convert to a taildragger, but for right now it’s more work than I want to put into it. I still have to remove my empennage and epoxy it back on and add triangular along the tail. I found my tail moves ¼” either side of center and there are wrinkles in the Ultracote right where the attach rod runs into the tail. This makes me wonder if the tail flapping back and forth is the flutter I’ve been hearing.
