The new Graupner Brushless Motor ULTRA 2804 is a
high-performance motor for all multirotor type of applications as well as small
foam airplanes and helicopters.
This motor is specially machined with high tolerances and
hand wound at the Graupner factory and can be ideally used with smaller 200 – 250
sized copters. The design provides optimal efficiency and good cooling during
operation. The special multi-turn winding and the 4.5 mm magnets ensure high
torque with direct drive for optimal performance and excellent power to weight
When combined with the Graupner Ultra Control ONESHOT 20A
ESC (S3056) the ULTRA 1806 will perform at best peak performance with
instantaneous and consistent control during each flight maneuvers.
We recommend using 5 -6 inches copter props like C-Props
1346.5x3 or Competition Race Props 1353.6.5x4.5 series.
