Default trex 600 cf mainframe repair

Bought a used trex 600 on craigslist. During my rebuild I've discovered damage along the bottom portion of the carbon fiber mainframe pieces. All the cracks are below the bearing blocks so I figured I should be safe with a repair. Esp since I don't have a ton of money to go buy two new frame pieces. Since it should only effect the structural integrity if the landing gear I'm going to repair it. Any suggestions? I was thinking epoxy and maybe a bracing material like wood or scrap carbon fiber.

Myself and 2 friends have repaired frames on a regular basis while waiting for new frames to arrive. We used epoxy and old carbon frame parts cut to brace in the important areas. Works a treat and finishes up being stronger than the original. Usually the next crash breaks anywhere but at the repair. .

Awesome! I felt like it'd be at least as strong but nice to have a second opinion. My first heli larger than a 450!

Sounds like you are not flying rough, so you should be fine if done properly. I personally wouldn't treat it like a fix, but more like a band aid until you can replace it. One other thing that we did a lot if we were able to on fighter jets was stop drill cracks. Drilling a small hole at the end of the crack to try and keep it from progressing. I have done that and then put a patch over it in the past.
