I agree with what Paul said. Also, you have to give Gary credit for designing a plane that will fly great with a cheap motor. Many people aren't willing to invest several hundreds of dollars on a brushless setup. I don't own an E3D, but I've talked to several people that do and they love how it flies. I've also watched many videos of it and it impressed me a lot. As Gary stated, it's designed plenty strong enough for any flight stresses. It sounds like he is continually tweaking his design to improve it. I like that!
