Yep that fact that the temps have gone up, speed has gone up, amp draw has gone up. I think it safe to assume I have demagged the rotor to some extent. So this thread will be more of a Medusa reveiw.

As to the timing setting the Medusa liturature says to run between 8-15 degrees advance.

The fact that so many are running ~1800Kv's led me to try the short can 3300's on lower gearing, basicly I traded motor toque for gear torque. These motors are really for a converted HPI NMT, I just wanted to try them out in my Maxx too see how they would perform.

Both motors blow the stock power system out of the water, unfortunatly the Ammo siezed a bearing and overheated, causing the demagnitization of it's rotor and ending the head to head portion of this thread.

Even before the Ammo was damaged it was running much hotter then the Medusa but did give better punch(could be timing related) and possibly slightly higher top speeds, hard to tell just by sight.

The Medusa is much smoother in it's power delivery, more predictable, and just easier to drive.

In the end this setup is only temporary till the MMM becomes available and I buy the motor I reallly want for the Maxx.

Why do you think the 3300Kv is too high for a Maxx? The Ammo is rated for up to 18.5v(61k RPM) The Medusa is rated at 60k RPM. I'm running them in the 45k range, I have an Aveox powered heli that only sees less then 41k spooling it up and when I shut it down after a flight.

The fact that no one would think to try a setup like this is as good a reason as any if you ask me. Ya sure I destroyed a $35 motor but who's to say the bearing wouldn't have siezed in the NMT causing the same damage? The Medusa is performing well at this point, will it continue too is what I want to find out now. No it's not a super high power rig that will run 60mph doing wheelies at 40mph, it will however do mid 30's with 10-12mph wheelies. I can easily jump the road in front of my house(my favorite big air jump). If this power setup continues to perform like this I might not even buy a differant motor but I do still want the MMM to allow for future performance increases.
