Title: kv confusion Post by: JKKASTA on June 01, 2010, 07:25:11 PM I have purchased 2805 1400 kv motor from Sai, he says it is 1400 kv motor but on other site I found the same motor they also says 1400 kv motor in main title but when i read it's specification it is described as 2840 kv so i am confused which prop shoud i use for this motor?

Only the italian site seems to have made a mistake of putting a wrong KV value in their item description.
If Sai has confirmed it, end of story ! Plus the size and shape does not look like it is a high KV motor (although that can be misleading).

Title: Re: kv confusion Post by: rcforall on June 01, 2010, 09:33:36 PM In any motor the KV can be changed by changing the windings .
The Motor was first produced by the manufacturer with 2850 KV, We then got it rewound by them for us to 1400 KV for use in Mr MOSS , so we have sold over 300 of these motor with 1400 KV and have comfortably used upto 9 " props on them in fact we also used it on a piaget with a 10 " prop on 2 S . Hence the motor supplied to you is 1400 KV . Sai |
