Skystars F722 HD Pro 4
HAKRC AIO F722 FC 40A ESC
Does it have the pads, UARTs, firmware target, and stack mount your build needs?
RDQ groups FCs by stack size: 20x20, 25x25/whoop, 30x30, wing, and accessories.
Availability / buy path
affiliate-readyNo merchant URL set yet. This tile is where per-store stock, price, and outbound links will live.
Normalized compatibility fields
These are public filter parameters from the compatibility profile. Missing facts are explicitly labeled Unknown; field confidence stays private for the engine/admin workflow.
Detected filter values
Known values from the same fields that power catalog filters.
Top-level component slot. Mirrors FPV store mega menus but keeps builder slots first.
Brand from normalized DB row or manufacturer tags.
Practical class like 5 inch, whoop, cinewhoop, long range.
Analog, DJI, Walksnail, HDZero, ELRS, Crossfire, etc.
20x20, 25.5x25.5/whoop, 30.5x30.5, and stackable VTX formats.
Hard blocker field for motor-to-frame fit.
4-in-1, individual, AIO, wing, or stack pairing.
F4/F7/H7/G4/etc. Useful for firmware capability and future-proofing.
Frame clearance and motor load sanity check.
Betaflight target, AM32/BLHeli/Bluejay, CRSF/SBUS/DShot/MSP, and similar protocol fields.
Draft/seed/verified/import state for catalog QA.
