Tail Touch CHALLENGE with the EFlite Viper 90. Touch, Wreck, or Both?

Getting Low Low and Slow Mo with the amazing EFlite Viper 90mm. Simply the best sport EDF jet on the market. Locked in, solid, predictable.
Do I push it too hard? Only one way to find out.

Great flying. Can you tell me where you have your CofG? Your CofG seems to be optimized for both upright and inverted flight and it appears to behave nicely on final approach. I'm gradually sliding my CofG aft as it's nose heavy inverted but you obviously have it figured out. I run a 6S 5100mAh GensAce battery. Thanks.

Thanks!
Have a 5500 70C roaring top about half an inch under the receiver tray. Pretty far aft.
