After toying with different motor types for my scale HC2, I'm wondering wheather the Actro 24-4 would be a decent choice given I've allways liked it in my Mikado.
With a kv=570, 14T pinion/170T main gear on 10S this gives a HS of about 1500 which would be as much as I would ever need. Given this motor has pretty good cooling characteristics so would be suitable running in a confined space, is there any reason why this might be a bad choice ?

Not sure how big your intended scaler is but only issue I can see is that small of a pinion is hard on gears if you are pulling a lot of blade. I've worked on some bigger scale helis and gear stress has been on of the biggest issues.

That was something I was concerned about. This is based on Trex600e mechanics with 4 blade head.

Assuming you are using 600mm blades, the stock main gear may be overstressed. It may work fine but I'd definitely keep a close eye on it. Don't know if you'd be willing, but stacking two main gears together would really help longevity.
