Fouga Zephyr throttle problem

[HarvesteR]

hello...

i recently downloaded the Fouga Zephyr: Updated by NorCal from simV, and while overall it is a very nice aircraft i have a little problem with it

the throttle lever does not reach 100% when i open the throttle on the joystick... it is necessary to press f4 to get to full throttle

needless to say, this makes flying a bit awkward, let alone taking off and taxiing, so i was wondering if there's a tweak that can be done to fix it

i have all my null zone sliders set to 0, so i am quite sure the problem is not with the joystick... even because every other aircraft i have works fine...

my guess is that the author intended this behavior so it would work something like an afterburner, but i'm flying on an X52 pro, and i wish full throttle would engage when i push the throttle past it's far detent

something tells me that some gauge must be controlling the throttle function, but i'm afraid i'm not too familiar with gauge programming in FSX, so a little help would go a long way here

also, on a matter that may or may not be related, i can't seem to start this plane from cold and dark... i am forced to press Ctrl+E
it doesn't help that all the tooltips are in french also...

thanks in advance

Cheers
