This looks like a great design. I had seen a write-up on this a while back and I had thought about building one. Although I wanted a pusher set up for my daughter so I skipped it. I think after the "pelican" bites the dust I will build one of these, or something similar at least.
Trouble is, when my daughter goes into the ground it is usually nose first at full throttle. She panics when she starts to lose it and doesn't think to throttle back.
