So let's move on. With help and suggestions of Andy01 I decided to use below powerplant solution depending on desired head speed:

I am using ;
ALIGN 750MX motor with 450kV
12S (44,4 V) Lipo = 2x 6S 5000mAh 25C
Gryphon HV BEC
pinion 13T straight teeth from Revco Hard one
ALIGN CNC Main Drive Gear/164T article: HN7019-2
KDE Direct Universal Main Gear Case Align 550/600 AT550/600-UMGC
ALIGN Autorotation Tail drive gear set article : H60020AT ,
ALIGN One Way Bearing Shaft article.: H60139AT

Calculation is: 44,4*450kV*0,9*13T/164T = 1425 RPM at the end of flight

Since I have decided to use left rotating main rotor I need to turn One Way Bearing around, I have one handy tool to to that

OWB is turned and main gear is ready for mechanics install !

Diffrence between regular main gear and upgraded one!

As said in first post third bearing blok was missing so I have added this great upgrade, motor will thank me later on

Coming next Motor install and front Torque tube gears upgrade,...
