| I'm designing a new beetleweight. I'm not revealing anything, only that I need a brushless inrunner between 100 and 200 g that can spin a 2 lb weapon over 10000 RPM at 11.1V and that is less than $50.
On hobby city there are so many motors that fit this that I have no idea which to choose! they're all around $20, and all have pretty similar specs. I narrowed the ten pages down into 6 motors.
motor 1 motor 2 motor 3 motor 4 motor 5 motor 6
And then there's a feigao 380-12L 2408kv, 170g, 400W for $43.19
and at the absolute top end of what i'm willing to spend - a Himax HA2825-2700 - 138g, 400W for $69.99
does anyone have any input? Do you have any other suggestions? I can guarantee you'll like this when I'm done though. :] | |

| I spent many hours scouring hobby city for a motor with very demanding specs (size, power, kV, amps, weight) and ended up with crap. I then found this amazing online comparison chart that, while still taking hours to sort through, yielded something I could use because the specs were really there (as opposed to guessing, as often is the case with HC) Notice that you can sort the data by any column--a real necessity, I think.
Maybe I just helped, maybe I just made your job harder.
Either way, this is a great resource for small motor hunting.
Have you looked at Scorpions? | |

| OMGTHATCHARTISAMAZING!YOU'REMYNEWFAVORITE. thanks! (I like the chart). a scorpion can handle quite a load (525W from a motor that weighs 79g?!!) but it is an outrunner. I actually ordered a 2900 kv turnigy from hobby city, but if that doesn't work as well as I want it to, I could use something else... | |
