This is an AV for the EA Tower Hobbies CrazE for Real Flight 6.5, and will also fly in version 7.5.
As flight experience with the real world Craze was gained, it was time for a performance increase. The motor was replaced with a AXi 2217/12 V2, and the cell count increased to 4. The AUW is essentially the same as 2217/12 weighs a little less than the 2808/24 and the 2.2Ah pack weight increased by only 2 oz.
On 4 cells, the power and current of the motor can be exceeded, even with dropping the prop size down to an 8 x 6. So, to prevent excessive motor power, the travel range of the throttle channel was used to set power at a little under the maximum. A power meter and tachometer were used for measurement, and the throttle maximum range was set to ~320W @ 12K RPM.
Most of the available power and thrust adjustments were used to then set the physics to closely mirror the real world CrazE.
Speed is of course increased, but more importantly the available higher power on 4 cells allows a noticeably lower current-- and that translates into longer flights.
