Default Vintage heli rotor head upgrade

I recently acquired an "American Helicopters 'Revolution 40'" rc heli from a friend. it was designed and produced in the 1970's. I am thinking about upgrading the rotor head and tail rotor and electronics to current technology but keeping the retro look. anyone done this before? any pointers would be much appreciated. The heli used a .40 airplane engine and fixed pitch head. Id like to see a DFC head or something similar from a Trex or other modern machine. Honestly, I'm not sure where to begin.

if there is already a thread on this topic, please point me that way.

here is a link to a vintage website i found which contains a little info on the original heli.

Thanks much,

Adam

My first heli, though I had the red one.

A week of tinkering was usually good for 3 minutes of flying before I hit or broke something

Nice. My first real heli was a kyosho Nexus. I really loved tinkering and flying the thing. I'm hoping to take advantage of the latest technology and get this bird in the air with "reasonable" control and performance, while maintaining the minimalist, vintage appearance. I have a FrSky Taranis radio and 401b gyro, servos. I'm considering the Super Tigre G-51 engine...should make about 50% more power and has similar size to a .40. At this point, which rotor head and tail rotor drive system to use seems to be the biggest hurdles. everything else should fall into place (metaphorically speaking :-)

Thanks. I'm looking for information on fitting a modern rotor head to this bird.
