RE: **Wren Turbines USA Open house**
Ron has also graciously invited us from Bergen R/C to come down and hang out for the day!! We'll bring the New 44 Magnum Helicopter down for a demo, and maybe the huge Turbine Observer as well...:) Looking forward to a day of kerosene burners...:):)

RE: Wren MW44 Turbine into 44 Magnum.
The Wren 54 also has the exhaust coming out sideways, albeit with a slightly rear cant to the exhaust, but no, we've never seen any issue with the sideways exhaust. With a 2 stage system like the Wren Heli series or the JetCat SPH5, most of the thrust is used up powering the second stage.. All that is left is some residual thrust, not enough to really affect the flight. The single stage heli engines like a PHT3 from Jetcat DOES have a high thrust component, and typically uses a Bifurcated exhaust, blowing it out to each side as well. Not having flown one of these types I cannot say that it affects it or not, but I have not HEARD anyone comment on it. We flew the 44 Magnum at the Winamac IN Funfly this weekend, putting it through the paces. Look for video to be up soon.

RE: Tail boom problems
Try adding a wrap of electrical tape in the area of the clamps. Start with one wrap, and add as necessary for a good snug fit. Can also try self stick sandpaper... Are you sure that it is torque doing it, or do you have a high freq vibration that is spinning your tailboom?

RE: Wren MW44 Turbine into 44 Magnum.
How is this for manueverability? http://bergenrc.com/uploads/GregAldermanBergenTurbineClintsB-Day2007.wmv We've been using the MW 54 Heli for over 3 years in our Intrepid Turbine. Apparently I've been lax in getting that word out. This engine is the new MW 44 Heli, that will be going into our 44 Magnum Heli, swinging 720 blades at 1950 HS for serious 3D Turbine Action.

Wren MW44 Turbine into 44 Magnum.
I've got the first production Wren MW44 here, going to be putting it into our .90 size heli. If it's cool, I'll post progress as we go. The engine is only available prebuilt and test run by Wren, and is completed as shown. Absolutely beautiful to behold.

RE: Who imports or sells a Gas (not nitro) heli?
[quote] isnt going to save you much money because a set of blades for the damn things cost as much as a couple cases of glow fuel.[/quote] Why would 710 blades on my gasser cost more than 710 blades on my 90??
