Hobbypartz Optima 400 Compared to E-flite 400?

Is there much difference in between these that I missed?
Thanks

The E-flite has more believable specs: 13A burst for its maximum is more realistic than the 28A for the Topband/Optima... that said, I've tested quite a few other Topband motors and they are pretty well made... keep the Optima 400 to about 150W and it will be okay.

I would be putting it in a Slow Stick, I just wanted to try and keep it as light as possible.

For 3s, I'd start with 9x5 GWS HD... then 10x6 GWS HD... check the amp draw but you might even get away with 11x7 GWS HD... that's what I use with my SlowStick using an AXI 2212/34... but then again I only draw ~10A because my AXI is only ~740Kv.
