Tsheten sent me these pictures via email since he couldn't upload to the forum due to technical difficulties.
Looks great, Tsheten!
I've seen the AW 95 in this configuration. Two changes that I noticed that most builders make are the the power shaft for the input pully to the tail rotor V belt was extended up a little more to add an additional bearing in a small cross section between the airframe struts that run up to the rotor system area. The other change is a "follower" system half way down the tail rotor drive belt to prevent excessive belt back lash/flapping. I found a video of a guy in Europe that built his own version of the AW 95.
I also found a place to buy a right angle gearbox for a tail rotor should you chose to upgrade to a gear driven. About 250 American dollars after shipment costs. better than 2000.00 dollars like the place in Australia or Vortech. Both of whom over charge for their parts. A place called superior gear. There is a guy in Ohio that rebuilt a Scorpion Helicopter. The original tail rotor was belt driven like the AW 95 first concept or some call it the "Choppy". Anyway this guy upgraded to a gear driven TR. The gear box was a 1900 RPMs input shaft with and out put shaft RPM 0f 2800 RPMs It's rated for up to a 54 HP max input with a restricted running temperature of no greater than 200F degrees . This guy says that his TR temp averages about 150 F degrees , so he's ok. No issues so far.

You can see the orange squre bracket assembly. You might be able to contact this guy and ask him for details on that upgrade. His CG looks a bit off and he needs to tweak his TR pitch...one foot looks as if it holds more pedal pitch than the other.
He has also modified the rotor hub and it looks like a sort of fly bar assembly. His version of course.
I'm not sure if he has a free wheeling unit/sprag clutch, which means he'll fall from the sky if his engines stalls. And the 2nd video, I'm not sure what it is.

Not sure about this one.
