My new Vario Turbine Cobra
Just had the first full tank of fuel with my just finished Vario Turbine Cobra... how cool is turbine flying

Provided you are smooth with the throttle (assume same with all turbines) then the Cobra is as easy to fly as a pod and boom.... very agile and I'm very impressed

Hope to post the video of the first tank once I get it sorted. More pics in my gallery and of my other heli's.

Hey Chris,
My source tells me you are the fastest human on the face of the earth on that throttle

BTW, thanks...bearings and jam nuts got here yesterday.

you shold not manage throttle .. it should be set to full at all times .. the ECU maintains output speed ... much smoother flying this way ..

NO NO.................................

Only if hes using a jetcat. If its a wren he has to make throttle curves.
ahhh one of the reasons i use JetCat and you will never find me dealing with a Wren !

Why would it be a Wren? Nobody has managed to succesully put one in a fuse yet, and the Vario is designed for the PHT3..

Although Wren do tend to be used more by 3D nutter types because they demand huge amounts of power.
Whereas civilised scaley types don't demand ultimate performance so, any old oil burner will do.


Ooops sometimes I can't help it you know!

I think the problem with the Wren, other than the lack of a governor, which I wont even mention, is the mechanics it is put into. They all seem to have gear ratios suitable for 1500+rpm headspeeds and so custom mechanics like the Rotortech are needed to get the headspeed down to a realistic level. I expect the Vario Benzine will gear down nicely as well.Peter Wales

And with Rototechs new ratio gearbox you can run the headspeed as low as 1100rpm as long as you increase your rotor size a little.

The trouble with Wren
Peter W I am in the process of getting a recently purchased second hand Wren serviced and upgraded to the Mark 3, their latest Ecu has a slot for a governor, Another note the Wren team now have helicopter pilots on the team maybe we will see a bit more interest from Wren with these addition
You are correct about the Vario with the hobbyparts Vario conversions there are 6 gear variations to choose from, some thing to suit everybody

Guys, its the Jetcat PHT3 and Mechanics. The reason why I mention to be smooth on the throttle / pitch is that clearly it does not have the same climb out rate at my Fury Extreme.... hence takes some getting used to if you are close to the ground and need to pull out all of a sudden. As I mention, this is the first time I have flown a turbine so will take some getting used to.

Its a great machine, not sure what to build next!

And it shouldn't. It is a scale machine and should be flown scale like to match the beauty of the bird. Nice Job.Chris D. Bergen

Hi Red Machine,

I'll have to arrange with one of the other flyers Colin to bring his turbine along to Hambleton Helis. He's got an Apache. They should look awesome side by side.

All i'll say is his heli was featured on Top Gear a little while back.....

Catch you soon

Regards

Matt
