Trex 450 motor comparisons

So far, I have tried The Hacker A20 6XL, The Align 430 L, The Mega 16-15-3 turn, The Aon
3500 KV, The Medusa Research 028-032-3400 KV, and finally, a few himax and e-flite
brushless motors (that weren't even worth mentioning on this page as far as performance
in a Trex).

I can pick two motors right off the bat that beat the rest hands down! The Medusa
Research 032-3400 is a very efficient motor that yields long flight times and a very suitable
constant head speed during heavier load moments. The second motor is the Hacker A20
6XL. This motor has loads of torque, being an outrunner can motor (with a built in cooling
fan), But can be somewhat harder on 15C lipos than the Medusa motor, Causing a loss in
flight time and efficiency.

If you were to ask me,
I'd go with the Medusa any day if I had the choice. If for some reason I was not able to get
the Medusa motor, The hacker comes in second, cost $20 less, and has the torque to pull
some great pitch tricks!

Following close behind in my preference, is the Mega 16-15-3 motor. This motor seems
to run a lower head speed on an 11T pinion, so you may want to hike to 13. It is also a very
solid performer, and can draw a lot form the batteries as well. Be weary of fligh times on
the Hacker and Mega motors.

Medusa Use 11T pinion from align or 12T Ikarus pinion. www.hobby-lobby.com
Hacker requires a special 16 or 17 tooth pinion available from www.modefosheli.com .
Aon will take 11 or 13T align pinions. I have heard of people using this motor on 15T as
well.
The Mega motor will work fine on either 11T or 13T align pinions. 13T for more head
speed, but less flight time. 11T for less head speed, more flight time, and cooler batteries.
The align motor can be run on either 11 or 13T pinions, However I found that on a 3 cell
2100mah 15C lipo, the head speed was 2990 rpm on the 11T pinion, which is plenty of
rpm as it is.

More to come.
