E- MAX GT2820 / 07 ENGINE

Brushless motor E MAX GT2820 / 07

Distinctive features of the E MAX GT series engines.

• improved profile of the front plate of the housing, which resulted in a significant improvement in cooling conditions. In practice, this means a lower operating temperature and, consequently, an increase in the efficiency of the engine.
• high-quality 0.2mm silicon steel coils, which lower the operating temperature and increase the efficiency of the motor.
• the possibility of double-sided assembly of the engine without its modification, it is provided by an additional - optional shaft attached to the engine. The package also includes the engine mounting cradle.
• increased diameter of the shaft, which reduces the likelihood of damage in unfortunate landings and increases the precision of the propeller's axial mounting - which directly reduces vibrations.
• higher quality bearings, better able to withstand high temperatures.
• greater flexibility in terms of the use of supply voltage and propeller
• increased efficiency
• new - solid and at the same time tasteful packaging that protects the precise motor during transport

General rules for the selection of electric motors to drive flying models:

• for training models and models that do not require a large excess of power, the upper limit of the recommended model weight given in the technical data applies.
• for aerobatic models, aerobatic mock-ups, high-speed models and models with a need for more excess power, the lower limit of the recommended model weight given in the technical data applies.
• in the case of a smaller number of power cells, the drive will have lower revolutions, and depending on the propeller diameter, higher or lower power consumption (larger diameter - higher power consumption).
• in the case of more power cells, the drive will have higher revolutions, and depending on the diameter of the propeller, higher or lower power consumption (larger diameter - higher power consumption).
• smaller diameter propellers, and therefore higher rotational speed, result in higher model speed.
• larger diameter propellers, and therefore lower rotational speed, result in a lower model speed.
• the higher the current consumption, the shorter the operating time of the drive unit, which results in the need for more frequent replacement of power sources.
• the use of a drive with more feed cells on the one hand increases the power of the drive unit, but on the other hand the demand for this power increases due to the greater total weight. Therefore, not always using the maximum number of power cells gives the best results. This principle applies especially to models with low weight (up to 2000g).
