pretty easy-
Download the manual from Jetcat website, go to page 46 of the manual-

look up the min/max turbine speed- make the changes there...

max speed recommended- 105,000 anything over this, and it'll start to self destruct.

hope it helps..
and for gawd sakes, don't destroy the turbine...

So far I have not been able to get in the secret menu to change the RPMs
Does some one have a link?
All I get in my manual, that's on page 46 it is about
"The R/C Check Menu" and "The INFO Menu" and when I go to JetCet USA on page 46 is "Airspeed Sensor"?

Evening Mcfast

On your GSU select Turbine Limits menu by depressing the Select Menu button (Membrane). Use advance button (-> +) repeatedly until Turbine Limits menu appears.

Release button and "Minimum RPM" is displayed. Use advance button (-> +) once and "MaxRPM:93000" will appear. Hold Change Value button and use advance button (-> +) repeatedly until 103000 appears.

Release Change Value button and turn Rx off.

Your Turbine is rated by the manufacturer for what Max Rpms?
Your turbine belts are rated for what Max Rpms?

cheers

Morning John (Mcfast)

Then your ECU is only rated for a max of 94000 rpms.

I have one PHT3 (Jetcopter)that was MaxRPM 83000 and could only raise to 85000. The ECU is version v4.0. I am pondering having it upgraded but with a Lama and PowerCat TS coming soon I may lose interest in older technology.

My second Jetcopter has ECU Version v4.9. It has the newer belts and pulleys. I had previously raised the Max rpms from 93000 to 103000.

My PowerCat has ECU Version 5.0 because it has the Kero Start Feature.
Max rpm is set to 98000. I plan to bump it up by increments of 1000 to reach max of 103000.

My Airwolf has ECU Version 4.9 as it is still Gas (propane) start. Max rpm is set to 95000 for now.

cheers

Hi mcfast , your updated ECU may be the problem , mine goes to 103000 easily , but have never flown with it , to much power at 93000 rpm.Unfortunately my ECU is under the floor boards and seats of my NH90 , and can't remember what version it is other than it's 5 something , therefor Donavan could well be correct.

Hi Ron

I do not know the up dates they did, they just said
"we put in the latest up dates" I phone JetCat this morning and spent at lest 1/2 hour on the phone and after programing the GSU for the longest time, they said now you can adjust the RPM you want, so I hang up the phone went in the GSU tried to adjust the RPM, put it did not work, I am still at 94K ?????????????????????????
