Trex 700 turbine governer
I've looked at various previous topics and can't seem to find a definitive answer on governers for the Wren 44 setup. Is it possible to fit a governer in the normal way with a magnet on the clutch bell.

In this configuration could the throttle output from the rxer just pass through the governor en route to the ECU?

I would appreciate any feedback on what can be done, governors tried and any gotchas when using a governor on a turbine.

For 700T models that I've seen on youtube doing 3D, do they generally have a governor or does the throttle curve suffice.

I have an SPH5 which picks up the speed from the fan on the gearbox which is essentially the same concept, albeit the Jetcat ECU may be more turbine intelligent around this aspect, if such intelligence is actually required.

This info is for a friend who is close to buying one.

Thanks

Geoff

Hi GC1,

I have tried running a govenor on the Wren44 heli with disarsterous results, trust me just run a throttls curve.

BRG, Craig.

While we didn't have disastrous results , we didn't have much luck with it either...

The throttle curve setup is NOT difficult, simply requires an optical Headspeed tach and a buddy to operate it.

If your gearing in the helicopter is correct then it should be REALLY easy, if the wrong gearing is used, then it may require a bit more experimentation.

Thanks for the replies, it looks like a throttle curve is the way to go.

Thanks

Geoff,

I installed a CSM governor to my MW54 engined XLV, but I could never get it to properly maintain head speed. Setting up the head speed using curves is the way to go, especially as the throttle curve is very flat. I was in the same boat as you, but to make life easier (as I tend to fly alone) I installed Vario's Electronic Speed Monitor Ord.No. 3555, that can give you an indication, by means of a bright LED if the head is at correct head speed (light on), or head speed is over (light flashing).

Good luck.

James

Thanks for the feedback and confirming that throttle curves are the way to go.
