Electric Motors ect?? Help !!
Hi all,
Right i have always flown nitro planes,but after going to a small model airshow this weekend i am really interested in 2 electric models (Simprop Turn left + Multiplex AcroMaster)
But i really dont have a clue about the numbers on electric motors (i have one that says Vortex 28/30/1270 on it?) And what Lipo's i would need and what the numbers on these mean,or even how to look after them best!
I know i am asking alot off you guys cause i really dont have a clue but i do want to learn and get into it,so any help on the electrics or the planes would be great,and thanks in advance !!

RE: Electric Motors ect?? Help !!
Not familiar with your motor but GENERALY the first set of #'s is the diameter of the motor or 28mm
The 30 would be the length or depth of the motor minus the shaft. The 1270 in your case I would say is the kv rating of the motor. It is the RPM that the motor will spin with 1 volt applied or 1270rpm's. 1270 would make it a middle of the road general purpose outrunner for 3 cell lipos I would say.
On lipos each cell produces a nominal voltage of 3.7v So 3 cells in series would equal 11.1v The other number on a lipo is the capacity in amps (2100mah equals 2.1 amps) This roughfly equates to the size of the fuel tank for a IC engine. Hope this helps you out. Others may chime in if I'm mistaken on anything!!!!!!!!!!!!!!!
Good Luck

That all makes good sence,thanks very much!
Now i can start looking to get into it,i also have 1600 3cell lipo and a 25 amp sc so this might get me going for the acromaster.
Like you said if anyone would like to add anything i am more than willing to listen!!
Again thanks alot !
