Sorry about the poor video, The camerman is a great flyer but a lousy camerman.

Here in Australia we have to get each new turbine model inspected and test flown before we get our "Permit to Fly". It is a little stressfull doing your maiden flight on a new model with the inspector looking over your shoulder. However this maiden was uneventful and it just flew great. I even landed during the miaden flight and turned up the max RPM of the engine.
I am lookng foreward to lots of good flights. We are having a jet meeting here next weekend, so I will be able to show it off.

Regards

Status: offline 		Wow, which engine did you use? What was the final weight of the plane? I've always liked the idea of a turboprop in a 3d aircraft, well any aircraft really.

Status: offline 		G'day mrbigg,

From idle to about 1/3 throttle is slow (>2sec), from there up < 1.5sec. I have not tried to adjust the turbine parameters yet so I expect it will get better.

Still very managable and easy to fly. The thing will go around at 1/2 throttle and you normally approach with some power on so a go around is no problem. I don't know how it would go doing hovering, yet I have seen videos of Somenzini doing it with a Wren powered Yak.

You get used to the throttle lag quickly.

The startup is great to watch.

I love my Turboprop.

Regards

Status: online 		I guess you'd get used to the lag after awhile. I've always heard about it, but nobody ever put a time on it.
