T-Motor AM5K 20A ESC

The Ultimate 5g Featherweight Speed Controller for F5K Champions

The T-Hobby AM5K AS 20A 2S is an ultra-narrow, pure-performance electronic speed controller meticulously engineered for high-stakes F5K and F5L glider competitions. By removing the bulky internal BEC and dedicating its architecture entirely to strict 2S LiPo voltage regulation, this ESC sheds every unnecessary milligram, delivering a blistering 20A of continuous current from a footprint that fits into even the tightest, pencil-slim glider noses.

Maximized Internal Airspace & Zero Drag Braking

In competitive soaring, space optimization inside the fuselage is just as crucial as weight reduction. Measuring only 23.6 x 10.55 x 5.01 mm and weighing just 5.04g, the AM5K 20A guarantees your internal layout remains clean and perfectly balanced. Fully compatible with the AMLINK programming tool, it allows you to configure aggressive brake settings so that your carbon fiber folding propellers snap flat against the fuselage the instant you cut the throttle, eliminating unwanted drag while you chase the weak thermals.

Core Features & Bullet Points

• Pure 2S Competition Optimization: Stripped of internal BEC weight and strictly optimized for 2S LiPo configurations, delivering high current response with maximum thermal and electronic efficiency.

• Ultra-Narrow Form Factor: At a mere 10.55mm wide and 5.01mm thick, this micro ESC effortlessly slides into ultra-streamlined F5K/F5L contest-grade sailplane airframes.

• Exceptional High-Amp Capability: Despite its microscopic 5.04g weight, it handles a solid 20A continuous and up to 28A peak current for reliable power injection during vertical launch climbouts.

• Heavy-Duty 16AWG Power Cord: Equipped with premium 95mm-16AWG power cables to ensure zero voltage sag and unrestricted power delivery from your battery during maximum throttle loads.

• Precision AMLINK PC Tuning: Supports comprehensive Windows software calibration via AMLINK, allowing professional pilots to fine-tune throttle strokes, PWM frequencies, and instant braking responses.
