Legacy Models

Initially 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.

Aimed at 550-600 size scale mechanics, the Scale Collection 4025HS was our smallest model in the initial Scale Collection range.

It didn't take long for the first Scale Builders to discover our 4035HS motors, and during the creation of the initial Scale Collection, a dedicated 4035HS was immediately added to the lineup.

The Tengu 4025HS was designed for 6s operation in the 550 helicopter class, and was developed alongside the initial XLPower 550 release.

Soon after the 4025HS we also launched the Tengu 4035HS. Initially concepted for 600 size 3d models, it quickly found its way into the f3c scene - and the Scale world.
