Default Can I narrow up a carbon fiber gear by making it two piece?

Any problems with making a single piece carbon fiber landing gear two piece? I'm building a scratch build and ordered an 8" wide gear and was forced to narrow up the fuselage to seven inches and would like to cut it in the middle and make it a two piece unless doing so is an issue.

You'll be creating a weak spot in the middle if you don't reinforce the joint. I'd think you could cut an inch out of the middle and then epoxy on a CF doubler on the bottom to keep it from folding.

Done all the time in F3A, for example

I've done it on several models, no problems.

I have done several comp arfs with seperate carbon gear. I usually sandwich the gear between two pieces of ply & use two bolts thru each gear leg. Easy to remove & install & so far very structurally sound....Gene

A few of the Giant scale Great Planes kits have 2 piece gear, they work just fine, it's all in how they bolt on,, obviously you'll have to drill additional mounting holes near the cut for proper support

2 piece gear is fine assuming they are properly mounted

Thanks to all for your insights. I will shorten it and bolt it appropriately.
