Default KMS Quantom 2826/05 question

hello all. I had this motor on an ultrafly sr-22, flying with 11.1 2200 lipo, it had excellent performance, way overpowered, but it crashed recently and its not repairable. The question i have is what is the Quantom 2826/05 motor most equivalent to? An eflite power 10,15,25? Im thinking its more like a power 10? it just seems kind of big motor. Thanks.

The Quantum is 170g... 900Kv....and rated for 45A max (400-500W)... that is a big motor.... the E-flite Power 15 is lighter (152g), same diameter but a little shorter (50mm v. 54mm)... but close to the same power rating.... that would be the nearest of that E-flite series to your Quantum
