Default Help me pick a motor/ESC to electrify a very vintage heli

My first heli back in the mid 80's was an American Helicopters Super Mantis. It flew on a .40 class sport engine and regular 4ch system and a gyro was optional. It was about the only way an 80's teen could approach the heli market. They didn't fly well and were a very early design for sure but I really like this machine. I have built up a stockpile and think it is time to put one in the air. With today's stabilization gadgets you can fly a brick so I would like to convert one I just bought so I can have a nice flying example. The model was not under powered with a sport .40 glow, extra power on tap would be nice but I have no intention of doing more than docile sport flying. I would also like to skip the belt drive system for the tail rotor which was the machine's weak spot and just go to a direct drive tail rotor/motor. I just don't know where to start with selecting main rotor motor and pinion and the t/r motor prop, with the right ESCs, and equally lost on pack selection. What I can do is create and share a 3D STL model to adapt the motors to the air frame. I would guess other owners might actually want to fly one.

And a pic from that site of that it looks like.
