Prop size Question

[spinwizard]

My question should cover all quads where you can update your props. I didn't find it on a search so..
As you can see, I have a modified Tarot 650 with SunnySkys 2216-15 KV650 motors and ZTW Spider 40amp controllers. It came with 12x 4.5 props and are what SunnySkys recommends. I have a set of 14 X 5.5 props and I want to know how they will effect flight and stability. What will the increased load on the motors and controllers be and can they handle it? I'm not interested in burning up in flight.
Thanks for any help you can give.

You could put a 12x6 on it, but I don't think I'd go higher with SunnySky motors. you should probably stick to 12x4.7 or 4.5 props though.

Here is a little chart I found, looks really good example.

Also take a looks at these 650Kv motors on HK. Notice that the Kv is the same but the number before it is much larger than the SunnySky motors. THis bigger number is the torque of the motor. This means these motors have more power to swing bigger props.
