Graupner G-Booster 80 problem
 

I have a Graupner G-Booster 80. At temps above 30c, it starts & runs to idle no problem. When I try to accelerate, the turbine struggles to pick up & flames out, with lots of white smoke.
It is like the turbine is getting too much fuel & cannot burn it.
I thought about increasing the acceleration delay, but there is no such adjustment in the GSU menu. I have heard there is a hidden menu available that has this adjustment in it, but I do not know how to access it.
The turbine runs ok in cooler temps. Unfortunately in Cyprus, that is not often.
Anyone any suggestions re solving the problem?

Hi Jim.
bit late in replying.
I use my G-Booster 80 in Dubai and have the same issue.
The air temperature is not the issue but the humidity.
If it is a humid day then the G-Booster turbines do not like it and flame out on start up. All sizes are affected here.
I recently returned mine to IQ engines in Germany for retrofitting with a different Nozzle guide vane which is suppossed to cure this issue, still awaiting its return, but hopefully will be ok.
We are coming into our winter now so humidity drops to nothing and the turbine works a treat.
