i am thinking of strengthening the fuse on my nexstar but im not sure on the best way to do it and what the best material would be to use. i have had a few rough landings and the landing gear is holding up with no signs of weakness but i have heard all the horror stories about this being a problem.

If it ain't broke... don't fix it.

FFhuber is right, you would have to remove the covering around the landing gear area.

I can't remember how the NextStar is built, but you definately should check if it uses nylon bolts. They are meant to break away on really hard landings. Breaking off usually means not ripping out the fuselage bottom.
