RE: Showtime 90 convert. Help
The E Flite 110 (as the specifications state) is really a 8S or 9S motor.
Read that as......8S if you have really good cells [hold 3.7 volts per cell under a 60-75 amp load]) ...... and 9S if you have so-so cells [that hold 3.5v per cell under a 60-70 amp load]. Personally, I would not put 10 cells on this motor. Something like a 17x8 on 8-9 cells will get you 7,500 to 8,200 RPM.
