[simpits-tech] Jetranger with turbine

[AMMS]

Hi,

I have a 3.05 meter jetranger, it flies great...:-)
There is a Jakadofsky turbine in it. Jakadofsky is also selling turbo-props.

Look at:

www.scale-heli.at for the heli's
and go to www.jakadofsky.com for the turbines.

	Oh COOL. Got any links? :)

	I'm thinking about a project myself, actually. Haven't built
anything since a 
GP Extra 300S .40 five years ago. I've been eyeing the Midwest Citabria, but

I wish it were a little more accurate looking (fuselage seems a bit squared 
off towards front, and top of aft portion of fuselage is straight instead of

sloped). Also thought about getting the non-collective "Sport 500" 
helicopter, but not sure I'd be happy with the sluggish performance of a 
non-collective rig.
