Re: CF and Fiberglass construcion 06 Dec 2013 18:26 #239

Ed,
Here is a link to my Pitts Model 12 I am building now. This is my graphlite Rod landing gear. I've been building models for 40+ years.

You can not believe how strong and light these are. Here's how I made the square tubing. Endless posibilities.

Enjoy.
