| | RC Groups - Proper power for Su-27 shockey XXL |
 | | Oct 19, 2005, 11:42 AM If it is the Mamba 3600kv, the 3x3 (measured is more like 3.25x3), 7.2amps, 9.2oz of thrust, 86mph pitch speed but a risky 30k RPM (10.5v under load, from 11.1v resting). |
 | | But, the Himax 2025 is a heavy motor (over 2oz), the reason the numbers come out similar is that the Mamba is a lower amp motor than the 2025, so it ends up with it's rpm dropping under the load more. |
 | | For use in the SU-27XXL I would suggest the APC 4.7x4.2, it should produce 18oz (510g) of thrust, 81.7mph pitch speed, at 10.2A, 10.3v, and 20,500RPM, a much more comfortable config for the motor, in all flight regimes. |
