Derived from http://www.thingiverse.com/thing:24282

I just removed the hand cranck, gears, bearing and replaced the parts with a brushless motor I had from a T-rex 450. There should probably be some sort of feet for mounting it on a surface, but that is up to you!

It is quite loud! So mind your neighbour :)

Edit 20/3/2013:
New impeller unit with screw for fixating the wheel on the axis of the motor.


Printed it without support, PLA.
The wheel is designed to fit a 3mm shaft.
Mount the motor in the housing and push the wheel on the motor.

nice improvement! well done!

Ooooh I was planning to design one myself but I had doubts if I could get it loud enough. Do you have a video???

Hi. No I dont have a video with the 450 running. But I have with a 540 brushed here: http://www.thingiverse.com/thing:64126http://www.thingiverse.com/thi...
The sound is the same with the 450 :)

would you like to make a video / sound clip for us so we get an idea of how it sounds

How much rpm? I have spare 450 parts too ;-)

My motor gives it 4000rpm/V with 11.1V lipo = very fast. I guess it would be better with a motor running about 7000rpm max
