I'm looking to build a skywalker x8 but there is a few improvements I would like to make. I would like to make a space frame from c/f rods and the shell from fiberglass. The reason for this is to increase wing strength, have a much larger space for components (hollow wings/larger inner fuselarge)and for a smooth surface finish for a more efficient/ fast uav. As I'm relatively new to all this can anybody see any potential problems with this idea? Tx signal with the carbon rods for example. Thanks in advance for your opinions.
