JetCat Hotcat 45 degrees offset PSG 3-blade rotorhead

[flyingdockp]

Hello,
I've started with converting a JetCat Hotcat to a 3 blade (PSG rotorhead) setup.

This helicopter was originally equipped with a Robbe Futura head, with right hand rotation, for which the servo's are placed in 45degrees offset.

So... some questions
1. just to be sure... no further measures needed for running this unit in a turbine helicopter, near the inlet of the turbine?
2. It has a 4 servo setup, 45 degrees offset, right hand rotation. I've learned that I have to use the 90 Velos setup (thanks!), and then I can most likely enter the tab advanced, expert setting in the cyclic phase area.
But... I'd love to have a very good setup.
So... do I use + or - 45 degrees offset? And... how should I see the servo setup in this? Normally CH2 would be the servo pointing to the nose, etc.
3. the rotor diameter will be +/- 1.80m. What would the preferred settings be to start with?

Thanks a lot!
