RE: 4*120/ST G-2300...
I did purchase the longer TNT landing gear, but have yet to use it as have not bent the stock gear up enough to warrent it's use. Have a little Fuji 32 nib I would like to break in on the 4*. It would add a couple of pounds along with the new gear, as it swings a 18" prop but would be fun to try before bolting it on the Midwest T-6 that I am building. I think the 81" wing would handle the the added weight, as that would make this bird come out at 14 pounds. Don't think I could hang the 4* on the prop, but sure would give her some poop on the vertical.
