I'm planning on building a 500 for sport and\or scale flying. What would the minimum requirements be? I currently have this spare Axi motor:

I also have a spare CC Phoenix 80 ESC.

Will 5S be enough especially if the heli will also carry a fuselage?

Thanks,

Balbs

I'd go 6S. Not sure I've seen anyone flying an AXI in a 500. For scale flying, the stock motor is probably ok. I really like the Neu 1706. Plenty of power, and it runs cool and doesn't draw much power. I run the CCHV45, and it is fine.

Hope this helps.

yup, with that low kv, i'd go 6S as well. you'll probably need somewhere around a 18 or 20 tooth pinion to get decent (2300-2500) headspeed.

Hmmm...I'll probably get another motor then since that Axi is rated for 5S. What do you guys recommend?
