High-Performance Propulsion for Competitive Gliders
The T-Hobby AM5K 280 (2800KV) is a premium, ultra-lightweight brushless motor meticulously designed for F5K and F5L competitive and sport gliders. Optimized for airframes with a 1.3m to 1.5m wingspan and a 180g to 350g take-off weight (AUW), this motor provides the instantaneous, reliable thrust required to reach thermal-catching altitudes quickly.
Engineered to Elevate Glide Performance
In glider competitions, every single gram matters. By stripping away unnecessary bulk, the AM5K 280 keeps its footprint incredibly light while boosting overall motor performance. Featuring a 20% enhancement in power efficiency and a 5% thrust improvement, it maximizes your battery output so you can focus entirely on tracking the wind and catching thermals.
