They're all built to last. People have complained that they can't destroy there bunny. If you're planning on getting a DA 50, for example, I would recommend any of them. The CAP however would be my first choice. I've heard of people coming in at 15.5 lbs. stock with a DA 50. Of course, if you got the Edge or Extra, you could get it down to 16-16.5 lbs. using micro servos on throttle, CF spinner, CF wing and stab tubes. The advantage of the Edge or Extra is that they can probably take a little more of a beating. Let me PM you an offer.
