TCMMRC Transformers F7 100A flight stack

TCMMRC has raised the bar for flight controllers. They have build the first 100A capable F7 flight stack called TCMMRC Transformers F7 100A flight stack. Well actually there was one 4in1 ESC before that could reach the 100A bar – it was Racerstar Reachup 100A. Now you can definitely say who was original manufacturer of this ESC. No coincidence why it looks so similar to the TCMMRC Transformers 100A ESC

The TCMMRC Transformer F7 100A flight stack is also sold under the DarwinFPV name. This stack is actually not super new, but very interesting and worth mentioning one.

The stack itself has interesting design. The FC part is populated on the single top side of the flight controller board.

While the bottom part of the FC has ESC MCU’s and ESC mosfet drivers, also some peripheral connectors. The signals to the mosfets are transmitted via the center connector element.

The ESC board has only the Mosfets populated. 

The flight stack VTX has on board mic. There is a free place for receiver installation on the VTX board, separated with a 1mm gap from the rest of the elements.

Interestingly TCMMRC suggests to install the lower stack board flat on the frame to ensure better heat dissipation.

Features:

F7 FC

  • Single-panel design, with ESC pin pads on the back which greatly reduces the problem of soldering short-circuits when soldering wires.
  • Onboard barometer and a black box. Reserved compass, GPS interface.
  • Up to 5 serial ports and 8 DShot output ports.
  • The flight controller reserves SH1.0 sockets and pads to meet both the requirements of free soldering operation and DIY soldering.
  • TYPE-C interface which can support larger current and convenient for pilots’ operating experience.
  • On-board 10V and 5V BEC (input voltage 2-6S) provide a clearer image display effect for image transmission.

100A 4IN1 ESC

  • Innovative structural design in the industry: the power board is separated from the control board. This design allows pilots to only replace the power board and minimize the error when replacing.
  • Two current models, 100A and a 60A, to meet the needs of different levels of pilots.
  • The layout of the control board adopts the principle of symmetrical aesthetics.
  • Uses a 4Oz copper thickness that balances beauty and performance.

Transmitter VTX

  • All wireless modules are placed on one board, which is more reasonable.
  • Reserve the receiver installation position so the receiver will no longer be jammed in hard to reach places.
  • 800mW image transmission, more user-friendly LED indication mode, clear at a glance.
  • Onboard microphone with immersive sound for an overall better FPV experience.
  • Copper skin can increase heat dissipation efficiency, avoid excessively high temperatures during work, and improve the stability of the board’s working ability.
  • There is a 1mm wide slot between the image transmission power board and the receiver to shield the signal and prevent emf interference.
