I ended up replacing the main gear with an Align helical 134t main and an 11t pinion and an Align tail slider and slider arm on the tail.

Other then those and the head and tail boom stretch it is a stock HK 500.

It flies great I still need to tune on it a little to tune out a small tail wag I had the first couple times I've flown it.
Hoping the weather will straighten up and the wind will let up a littl to get it and my stretched 700 to the field and shot some video of both.
How did those servos work out for you on the cyclic ? After trashing my gaui 550 (forgot to check my pitch curve, it came down real quick and parts went to flying) it looks like I'll have to do a stretch on my 500 for my jet ranger build I had originally ordered 3 of those servos (power hds) for my 500 blackhawk build, but got to reading they werent good as cyclic servos, so I used them for tail servos on a couple of my helis. After crashing the 550 and it cutting the servo wires in half during the mishap I'm going to need some more cyclic servos for my blackhawk. I got some solar digitals to go on the 500 which were intended for the blackhawk fuse. I may go with another set of solar digitals on it as well.
