It is nice to have the option. Half of my planes have fiberglas and half have ABS. Wanna guess which half have cracks in them? All the ABS ones have cracks, usually at the screws. Sure with fiberglas you have to take off the prop or carve out the headers and glow plug, but that's why it is a hobby. I'm not one of the guys that goes to the field to work on planes, I take two so that I can fly. If I have problems, I usually don't take it apart right there regardless. I want something that is going to last a long time. And I want this plane to be a centerpiece for a long time.
