Hey guys

Is it normal to have this huge delay on throttle response on the PHT2? Would it be because of the governor? Or is there something wrong? All is new on this turbine, never flew it.

hi Cal,
Thanks for the PM, Yeah I fly jetcat now since Wren don't make the MW54 anymore, when I watched your video it is clear your flying it as you would your WrenMW44.
The PHT2 turbine is single stage which are designed for scale application where you fly at a constant RPM, the Jetcat PHT3 and PHT2 are not governed in the truest sense,both are designed to run at 100% and then geared down through pullies and pinions to a set RPM, on my PHT3 it is around 1250rpm, so I have a normal curve on my futaba which is to start up the turbine,0 50 100, I then click into idle up which is set at 100% straight line and then fly, so all I am controlling when flying is the PITCH. Once I land I bring the stick down to just below mid stick ( -2 degrees on pitch curve) and then click out of idle up, I then, once turbine has spooled down to idle, switch it off and allow the cooling down process.

As to your throttle spool up, on my PHT3 I can adjust it within the hand held terminal in the limits section, it is normally set to 20 or 25 seconds and can be adjusted from 5 seconds up to 30, purely for kindness to the belts I have mine set at 30 seconds spool up, so if I pumped the throttle like you did in the video nothing would happen as your video demonstrated.. this is purely the way they work and nothing wrong with the fadec.

On the PHT 2 you access this via Limits Menu, it is set to 40 secs as default according to Manual ( if my german is correct).

Hope this helps matey.

Matt

All The Best
