Hi Guys,

I am building a autonomous quadcop prototype and have some tight budget.
I have got 2 choices for motors:

Emax XA2212 980kv vs
 or
EMAX MT2213 935kv

Please suggest which one should i go for.

Also using individual ESC would be better or 4in1 ESCs are better?

Thanks,
Shashank

Welcome to the forum, shashaxk  Smiley

Selection of motors solely depends upon your Estimated All Up Weight (AUW) and Motor to motor distance.
And 4 in 1 ESC is cheaper than individual ESCs by few 100 bucks . But once a ESC fails beyond repair in a Quattro ESC , you have to change the whole set - which is costly . Still Quattro ESC is cheaper - and allows a tidy Installation .

If you post your required payload, estimated AUW , Endurance, and Motor to motor distance , I can suggest good Motor - Prop - LiPo combinations Smiley

If you are tight on budget, why don't you go for any of those quadcopter kits from rcmumbai, or quadkopters ?

Thank you Sooraj.

Estimated AUW would be 180-2000gms, m2m distance ~800mm, flight time 15-20 mins in hover mode.

I did looked at the kits which are providing Emax XA2212 with 4in1 Esc.. hence this post Smiley

Re:

Damn, you cant use a 2212/3 size motor on a 800mm quad with estimated auw of 1800-2000 grams for a 20-30min hover.
You need those pancake motors for this job

As said by Nitesh, 2212 motors won't be efficient enough to provide the 30 min flight time with such a big quad - this motors will work good up to 600mm Motor to motor .

For a 800mm Motor to motor and 20Min Hovering you have to look for some big , efficient motors . Turnigy multistars are the cheapest option .
