Quadcopter Back Loop How to with Blade mQX

The Blade mQX is a great starter quad:
I've been wanting to do loops and rolls with my Naza and APM quadcopters, but needed a cheaper alternative to practice with. So I've been practicing loops and rolls with my Blade mQX quadcopter.
I cover back loops in this how to, but a lot of the same principles can be applied to front loops as well as side rolls. In the vid I try to do my best to break down the steps in slow motion and showing the transmitter control sticks.
I think the two most important things to remember are:
1. Make sure you give a bit of throttle before you loop or roll. In the vid I go from hovering at 50% and increasing throttle at 75%. Your settings may vary.
2. NEVER zero your throttle. This is a big mistake I learned the hard way. If you zero your throttle then your pitch input doesn't matter. Your quad will drop to the ground.
My disclaimer is my loops and rolls are not as pretty as some of the pilots who have their expos tweaked and are pros. They can loop and roll 3 feet off the ground and barely lose any altitude. This is just a demonstration of the basic motions to do a loop since it's something I've been looking for with clear instructions.
Please let me know if you have any questions or suggestions on how to improve this technique.
