Tekko32 F4 Bigfet 50A 4-in-1 ESC

F4 MCU / PWM output up to 96K / 4~6S / BLHELI32
Tekko32 F4 BigFET is made for those that use 20x20 mount and also need the power of big MOSFET. The F4 MCU & quality big MOSFET onboard will provide smooth control, quick response, and big power for racers and freestyle pilots.

Features:

• New F4 MCU, much faster than F3 & F0
• PWM output up to 96K (default 48K)
• 20x20 Mount design with big MOSFET
• A separate drive & control circuit broadens the current capability of the drive circuit while reducing the electrical interference to the control circuit.

Specification:

• Continuous Current: 50A x4
• Burst Current: 60A x4
• Supports 4-6S battery
• Supports DShot 150/300/600/1200 & MultiShot/OneShot/Proshot/PWM etc.
• ESC telemetry Supported
• Onboard analog current sensor
• No output BEC
• BLHeli_32 firmware
• 1000uf 35v capacitor included (highly recommended for 6s setup)
• Amperage meter scale ratio: 168
• Dimensions: 39x36.5x6mm / Weight: 11.8g
• Mounting holes: M4 30.5x30.5mm (M3 grommets included)

Atlatl HV Micro

Features

• Compatible with all major FPV receivers from vendors such as Fatshark, ImmersionRC, etc.
• Supports the standard 40-channel set: band A, B, E, Fatshark, and Raceband.
• SmartAudio input allows remote control by the flight controller. Change channel, transmit power, and more from Betaflight OSD, flight controller USB port, Taranis Lua Script, and more.
• All parameters are controllable via push-button on the side of the unit, for cases where SmartAudio is not used.
• MMCX connector is durable and easy to use. Rated for 100’s of mating cycles. Easy and quick antenna changes. No more ripped-off UFL connectors.
• LED indicators for channel, band, and power. Allows easy check of vTX parameters simply by glancing at the quad.
• Variable transmit power from 25 mW to 800 mW. Use 25 mW for a race and then easily switch to 800 mW for freestyle.
• 0.5 mW True Pit Mode allows you to power up safely without the risk of knocking other pilots out of the air.
• Built-in microphone, so you can listen to your motors while you fly, no matter how far away you fly.
• Standard 26mm form factor allows you to mount the Atlatl directly on your flight controller stack.

Specifications
