I think the Power 52 would be pretty good on 5S and a 15 or 16" prop; it'd probably be a little "hot" on 6S and would have to use a smaller prop, like 13 or 14", as I do on my Value Hobby 600kv motor. The Power 52 shows an overall diameter of 50mm, and weight of 346g, so I'm guessing it's pretty close in size to the 5055 motors we've referenced.
I did get to fly this exact plane last summer at a local flyin; owner was a "glow" guy and made the mistake of buying the Power 60, because, of course, a 60 is better than a 52, right?
He was running it on 5S 5000mah packs and a 15" prop, and it was a complete turd, as far as 3D. I told him it needed the Power 52 on the same prop, and about 3300-4000mah packs for less weight and more power; he put a DLE20 on it instead and promptly crashed it...oh well.
