Made in India FC + ESC Stacks
A stack is a flight controller and 4-in-1 ESC sold as a matched pair, and every stack on this page is designed and built in India. Botlab Dynamics' BotStack pairs the solderless BotWing F405 or F722 with a BotDrive 50A or 55A AM32 ESC; Zerodrag's Nova-Boost (F4), Warp Boost (F7) and STRIX-BOOST (H7) sit on the Boost 55A AM32 ESC; Darkmatter's STACK 450 and 750 combine the BRAHMA F4 or F7 controller with the VISHNU 50A ESC. All are 30.5 × 30.5 mm, 3–6S, Betaflight.
Which stack
- Budget 5-inch — Botlab BotStack F405 + 55A AM32, or the BotWing F405 + BotDrive 8-Bit 50A.
- Feature-rich 5-inch / 7-inch — Botlab BotStack F722, Zerodrag Warp Boost F7, Darkmatter STACK 750 (F7).
- Top-end — Zerodrag STRIX-BOOST: H7 controller on the Boost 55A AM32 ESC.
What you get with a stack
Matched connectors and harness lengths, one firmware target that the maker has tested against its own ESC, and one point of contact for support. Botlab's stacks are fully solderless — receiver, VTX and GPS plug in — which makes swapping a damaged board a ten-minute job.
Compatibility notes
All stacks here use the standard 30.5 × 30.5 mm M3 pattern and fit any 5-inch or 7-inch frame with that mounting. They run 3S–6S; use a capacitor across the battery input on 6S. ELRS receivers from the same makers (BotLink, Nexus1) plug straight in.
