Beta 4025HT

Iniitially developed as Tengu 4025HT/1190Kv alongside the release of the SAB Kraken 580 helicopter, this motor gave birth to an entire lineup of configurable motors: the Beta Series.

This model is no longer part of the active EGODRIFT product range. The information on this page is kept available for setup reference, spare-parts guidance, and compatibility support.

Model history

With the initially announced Kv target for the SAB Kraken 580 having been on the high side, we made the decision to treat our 4025HS motors to a slight base height increasement, to allow us to bring the popular YY winds from our larger (45-sized) motors to a smaller form factor, and released the Tengu 4025HT/1190Kv.

Soon after, we treated our existing 4035HS platform to the same upgrade, and introduced an entirely new size to our lineup: The Beta 4030HT. With its low weight, high torque (HT) and cooler operating temperatures, the 4030HT motor quickly went on to replace the 4025 size in the 550-580 class, but the 4025HT soon found a new home in f3a drives, and would pave the way for future generations.

Shaft compatibility

The Beta 4025HT was available in 3 different shaft options: a 6x32mm, 6x40mm and a 5x32mm version.
