Neu 1107 in a cobri

Looks like it'll fit and probably work well enough in my EF Yak54E.
Neu 1107/1.5Y It's the heli version, so 3850KV. Has the 3.2 shaft, which was odd since the sticker said 2.3. No matter. I put it in the lathe and machined the fins off the case (I'm not planning on selling this motor, so the appearance isn't important to me) and it fits beautifully in the cobri box. I put a 16t pinion on it, so the ratio is right about 4.5:1. On 4S this looks like a fantastic 600w setup with effeciency better than anything else for the money.

Hi Lance,

What cobri box is that, the 20 or 28? I thought I had read there was some problem fitting the neu's in the cobri box - I have a 1105 I want to mount in a cobri box but dont want to spend the $$ if it aint gonna work!
