Converting To Electric Flight |
| *Conversion may require some minor airframe modifications along with
installation of motor mount and motor, electronic speed control,
battery tray and battery packs. We also recommend a separate BEC or
battery pack for larger models. |

Examples of Airplane Setups: NOTE: All data measured at full throttle. Actual performance may vary depending on battery and flight conditions. Hangar 9 Ultra Stick 40 ARF (HAN1675 / HAN1690) Option 1: | Amps | Volts | Watts Input | Watts/Pound | RPM | | 51.5 | 14.4 | 745 | 128 | 8250 |
Expect very strong performance with very short take off rolls and a great balance of thrust and top speed. Average duration is approximately 15-20 minutes depending on throttle management. Option 2: Motor: Power 46 ESC: 60 Amp DualSky DSXC6018BA Prop: APC 13x8E Battery: Sanyo RC-3000HV 14-Cells (7-Cell packs x2 in series) Flying Weight w/Battery: 6.7 lbs
| Amps | Volts | Watts Input | Watts/Pound | RPM | | 44.0 | 13.4 | 590 | 89 | 7950 |
Expect good performance with a good balance of thrust and top speed. Average duration is approximately 5-7 minutes depending on throttle management |
