Any suggestions on how to setup my throttle and pitch curves to quit tearing out my main gear on my HDX500? What's the trick to starting up when your soft start ain't worth a darn!!! A new ESc at this point isn't an option.

I am using the Hobbywing Pentium 60A with a Hyperion 3025-10 motor and the 94t Mian gear with a 24t pinion and a 4S 3700 battery.

Is the Microheli Gear worth the extra cash or is it just machined smoother?

Thanks

Without a decent soft start your going to tear up the main gear especially with 4S. You can modify your frame and use the 130 or 140T main gear with the right pinion and the problem will be very much solved if you make your throttle curve have a slow rise. If you can just use a good slow start ESC and save yourself time /money/headache.

If it cannot fly on it's own, then I won't be much help....

You need to make sure your motor mount plate and motor screws are tightening down and not just bottoming out and feeling tite.I had this very thing happen to me and stripped 3 gears before finding the screws bottoming out.
