I got twoo Bell 47 , a G (without hydraulic and a G3 that I want to convert non turbo)
I read your advice and I have some questions
1/ what's the difference between low dome piston and high dome piston?
2/ Do you have paperwork to convert G3 TO NON TURBO (stc) ?
My engine is a TVO 435 B1A
3/ May I fly with this engine without the turbo ?, I already make a test (15 min) on the ground without turbo and the engine run very well
I believe there was a UK modification to remove the turbocharger, where you would find it I do not know.
The CAA would have a copy but the copyright would lie with whoever developed it. So not sure they would be forthcoming.
This aircraft is modified to non turbo.
G-CHOP
Maybe the owner could help.
