Once in the air, with enough (a lot!) of trim-- and she flew beautifully, at about 2/3 throttle.
I agree that the CG could be an issue. My gut is that the jet will rotate and lift off at a much slower speed than what we are use to seeing. (The scale effect will be strong in this one ) If the CG is too far forward it just won't rotate, and without rotation it won't have the lift needed to fly. Don't forget to include the fuselage and stab areas in the CG calculations. Otherwise it will be nose heavy for sure.
PS... The video was still very cool! !
