Hey.. every one .i had made a ft storch with coro and it weighs around 1300gm with battery will it fly with a 2212 13 t 1000kv brushless motor.plz  help

Instead of replying to your PM I'm replying here

A2212/13.RPM/V: 1000KV.Batteries: 2-3 Li-Poly.Efficiency: 80%.Current: 4-10A (>75%).No load current: 10V/0.5A.Max. transient current: 12A/60S.Shaft diameter: 3.17mm.Dimensions: 27.5*30mm. Weight limit for compatible model plane: 300-900g. Compatible propeller model: APC 10*5/ APC 11*5.5/ APC 10*4.7

Let's assume from the above you are running on 11.1 V, with 10*5 prop, drawing 10 A
Your Input wattage will be 110 W, and with 80% motor efficiency, Output (Useful) power is 88 Watt

You have mentioned a model weight of 1300 gm, which is 2.86 lbs. This kind of model (high wing cabin monoplane) would need 75 w/lb ++
So, obviously it will be underpowered!

Further, the 10*5 eProp spinning at 7500 rpm will need about 110 Watts @ 11.1 V 10 A, and will produce a maximum thrust of about 700 grams

So this motor is clearly underpowered

You can go with a 2836-1100 KV with a 10*5 prop. It will suffice

Ammar Badar, I don't know your flying skills level, but if you want more action, go with a 3536-1050 KV
