Anybody using a Rotomax 50cc....?

Anybody using a Rotomax 50cc on a 87 inch (or similar 30%) 3D ship on 10s?

Just curious that very little info is available with that particular configuration as 12s seems the prefered setup. Thanks in advance.

I have 2 Rotomax 50cc but they are not stock (rewound with thicker copper wire) so I can't comment on its original performance.
I can provide some additional info which may help you:
- The real (measured) kV of this motor is 192-198 (far from the 172kV of the specs);
- 10S will not fly a decent 3D IMHO, check the videos with the below setup:
  • Fly Model Extra 330SC
  • Rotomax 50cc (rewound to 198kV)
  • CC Edge 160A HV ESC
  • CHL 12S 5000mAh 70C Graphene packs
  • Aerostar 23x10 electric (now a 23x12 gas) wood propeller
3rd flight of the Extra (23x10)
Fly Model Extra 330SC 50cc Electric Powered - 3rd flight (5 min 45 sec)


3rd flight with a 23x12 gas prop (after plane's repair).
Fly Model Extra 330SC 50cc Electric (23x12 gas prop) (5 min 18 sec)

Thanks Ronald for the feedback. I was afraid most 3D pilots chose the 12s setup for a good reason. I will have to go with that solution. By the way, very nice flying!

No problem, this Extra 91" was my first 50cc setup and based on the overall performance, motor temperature and flight times I have decided that I'll be running my next 90-92" planes on 14S 5000mAh with slightly heavier motors.

I got a great deal on a Vantex Edge 88" so I'm moving the complete 12S power system to it. Hopefully the Rotomax 12S setup will work better on a slightly smaller airplane.
