Anyone out there done anything other than the closed loop set up on the Hype 3D?

Does the closed loop work well enough and positively enough?

Anyone using a pushrod idea?

I'm not keen on cutting into the rear of the fuselage and mounting standard sized servos as I think the strength will be compromised. Neither do I think mini servos will stand the test of time on the elveators.

Any thoughts/info?

Thanks
