Default Epic Duo2 13.5T vs. Trinity Duo2 13.5T

Any difference between these two motors performance-wise?

The Trinity is the original version of the Duo and the Epic is the new version, the Duo 2.

Performance wise, I cant comment on the Duo 2 (yet) but the original Duo is a rocket! Even geared somewhat aggressively, mine still rarely goes over 150 degrees.

Team Epic now owns trinity and trinity is no longer the company name....

I have heard talk of the Tekin 13.5 being faster than the DUO2's 13.6

The difference in the 2 motors are the motor with the redish colored sticker is an old pic of the original duo and the other is the new duo2. The duo 2 has more pull than the old motor and is also dynoed and tested with the dyno results posted to the outside of the box. You cant go wrong with either motor.

Cool, thank you. Also, are these rebuildable like the Novak Ballistic? Also, I haven't heard of the Tekin 13.5's being faster than the Duo2's or Ballistic's. Apart from trying all three, what's your take?

It would be great if manufacturers stepped up to the plate to provide consistent data, like the Nitro engine manufacturers, which provide RPM and HP.

Epic Duo2 13.5
RPM: 3402 RPM/1.0volt
Power: 7.62 watts/1.0volt
Torque: 116.8 Nmm

Novak Ballistic 13.5
RPM: 3300 RPM/1.0volt
Power: ?
Torque: ?

Tekin 13.5
RPM: ?
Power: ?
Torque: ?

Nitro HP numbers are as phony as a $3 bill...... There's too many variables to document real world numbers on BL motors.... Batteries, timing, ESC etc etc etc. Buy whichever one you want.

The Novak Ballistics have the same internals as the SS motors... just with replaceable stators and adjustable timing. I've run Tekin and Novak motors back to back and my Tekins have more power and run cooler. The Novak with a 13mm rotor is alittle better, but still runs 30' hotter than my Tekin with the same gear/timing. I've also had some stout Speed Passions that were impressive

Ended up order the Novak Ballistic 13.5T. The key attributes that made me choose:

1) Ballistic can be rebuilt, and you can swap the stators to run in different classes, including modified, 10.5T and 17.5T. Stators are readily available and cost $29.99.

2) The sensor wire/harness is removable.

3) NovakTwo actively participates on RC Tech, so if I have a question, he can answer it.
