Package Includes:

1 x Quanum 40A Multi-Copter Brushless Speed Controller Programmable ESC with 5V/3A BEC

T Motor AT 75A 6S is compatible with various flight-control systems and supports a signal frequency of up to 621 Hz at a. It has a special core program for multi-rotor controllers that greatly improves throttle response and specially optimized software for excellent compatibility with disc-type motors. The twisted-pair design of the throttle signal cable effectively reduces the crosstalk produced in signal transmission and makes flight more stable. All settings except the timing are preset, making usage simple, highly intelligent and adaptive.

Features:

1. Multiple protection features: Low-voltage cut-off protection / over-heat protection / throttle signal loss protection.
2. 3 start modes: Normal / Soft / Super-Soft, compatible with fixed-wing aircraft and helicopters.
3. Throttle range can be configured and is fully compatible with all transmitters currently available on market.
4. Smooth, linear and precise throttle response.
5. Our pocket-sized Program Card can be purchased separately for extremely easily programming the ESC at the field.
6. With a program card, you can activate the music playing function of the ESC, and totally there are 15 songs that can be selected

Package Includes:

1 x T Motor AT 75A 6S

When using a lithium battery pack of more than 3S, a switch‐mode BEC has much higher efficiency with lower heat. For a traditional linear BEC, For example, a 4S lithium battery pack has a typical voltage of 14.8V, in order to let BEC output 5V/1A, the current flow into the BEC is at least 1A, so the power on BEC is 14.8V* 1A=14.8W. But useful output power is only 5V*1A=5W, so the efficiency of the linear mode BEC is
just 5W/14.8W=33.8%, the redundant power 14.8W‐5W=9.8W changes to heat, which makes the BEC very hot, and makes it enter a protection state, thus unable to work

Features:

1. Provide large output current
2. Overcurrent and overheat protection function
3. The max efficiency of the chip is up to 93%
4. The small size and the light weight make it very convenient to use
5. Shows the working status with an indicator(LED)
