David ,
Thanks for you replay
I guess the main advantage of the three blade would be the a bit noise reduction... and here in Switzerland it would be a "plus".
I discuss with MT-Propeller and they confirm to me you could have a rear 3 blades and a front 2 blades... interesting.
On my 206 I installed a 3 blades and the noise decrease a lot.
Thanks for your returns
Alain
