E -Max brushless electric motor.
- engine bed
- o-rings for fixing the propeller
General rules for selecting electric motors in aircraft models:
- 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 propeller diameter, higher or lower power consumption (larger diameter – higher current consumption).
- smaller diameter propellers, and thus 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 to replace power sources more often.
- 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).
