My buddy was telling me there were many motors to power my Trex 450 v2 that had more punch than the Align 430XL. He likes the scorpion motors. I was checking hobby city to see what they had and this motor is 4850kv!!! At 16 bucks WOW !!! My only concern is life/longevity with regards to bearnings etc. The reviews are pretty good but nobody reviewing has had it for any length of time at the time of the review. Has anybody had experience with this motor? I have some towerpro airplane motors and they work great .

Get a scorpion motor, have the power, have the long life and have the smooth balanced quality you get with them.

What headspeed do you want to run it at?!
kV=4850 will give you at 3s and 11T pinion (smallest reasonable for 3.2mm shaft) over 3000rpm. Either that or you will need to throttle back, where a question why do you need 4850rpm/V for in the first place would arise.

I'm finding that the more proficient I'm getting at flying my Trex I'm moving my throttle curves higher and higher. I'm at almost 100 % all the way across and still want more power when punching out inverted (when I get scared). I just want more power, I don't know what head speed will give it to me but I do know that prolly 3000 + will give it to me. What is the stock align 430xl usually doing at 3700kv with 13t pinion?

Ok just did the math and 3700*11.3/13 gave me somewhere around 3200 rpm theoretical.

You know I'm using Align pro 325 woodies, I wonder if carbon fiber blades would give me more punch?

you do realize that the head and blade roots are only so strong and too high HS==disaster?

it's been reported by those who have tried both that this motor has more torque than the 430xl...11 or 12T

it's cheap enough...700W

Yes frac an 11Tpinion would be a must for this motor. Lets see: 4850*11.3/11 equals theoretical 4982k Is this in real life going to provide more punch or bog down? I am wondering about efficiency. Some of the reviews state that it is very hungry for milliamps and are getting shorter run times.

That 3700 turnigy looks good but on the discussion someone mentioned using alot of watts just to hover. Turnigy makes an SK line that is more efficient I wonder if they have one in this category...I'll go look.

rogman, here's something to play with that might help:

someone here uploaded the 3700 stats to it

Awesome thanks! I checked the SK line and nothing...
