The workhorse whoop board: F411, 12 A ESCs, built-in VTX and SPI ELRS. Takes a second cell.
Recorded specification
Every value carries the source it was read from. A property with no recorded source is marked as such rather than presented as a fact. If one of them is wrong, tell us: it is the fastest way it gets fixed.
| Property | Value | Source |
|---|---|---|
| Stack mounting pattern decides fitHole spacing of the mounting pattern. | 25.5 × 25.5 mm | Oscar Liangchecked 2026-07-27Quote 1, below the table |
| Control link protocol decides fitThe transmitter-to-receiver RF protocol. NOT the same as the receiver-to-FC serial protocol. | ExpressLRS | Oscar Liangchecked 2026-07-27Quote 1, below the table |
| Video system decides fit | Analog 5.8 GHz | Oscar Liangchecked 2026-07-27Quote 1, below the table |
| Maximum transmit powerCompliance-critical: most countries cap unlicensed 5.8 GHz transmit power, and the cap differs between them. | 400 mW | Oscar Liangchecked 2026-07-27Quote 1, below the table |
| Minimum transmit powerDecides whether a high-power VTX is merely restricted to a setting, or unusable here. | 25 mW | Oscar Liangchecked 2026-07-27Quote 1, below the table |
| Minimum cell count decides fit | 1 S | Oscar Liangchecked 2026-07-27Quote 1, below the table |
| Maximum cell count decides fit | 2 S | Happymodel product specificationschecked 2026-07-27Quote 2, below the table |
| Continuous current decides fitAmps per motor the ESC sustains continuously. Vendors also quote a higher burst figure; this is the continuous one, the number that limits which motors the board can feed. | 12 A | Happymodel product specificationschecked 2026-07-27Quote 2, below the table |
| ESC firmwareDecides the configurator and the features, like bidirectional DShot for RPM filtering. Bluejay runs on BLHeli_S hardware but is its own firmware, so both names appear on the same box. | BLHeli_S | Happymodel product specificationschecked 2026-07-27Quote 2, below the table |
| Integrated receiver decides fitAn SPI receiver on the board satisfies the receiver slot and bypasses the serial protocol. | Yes | Oscar Liangchecked 2026-07-27Quote 1, below the table |
| WeightBuild-critical rather than compat-critical: needed to answer registration and class questions. | 3.8 g | Oscar Liangchecked 2026-07-27Quote 1, below the table |

This listing does not say which warehouse ships it. Most orders leave China, so expect import VAT and a carrier handling fee unless an EU warehouse is chosen at checkout.
No current price: our own estimate is 500 SEK. It is a rough street figure rather than a quote, and the retailer above confirms the real one.
Some links on this page earn us a commission at no extra cost to you, and that never affects any verdict on it. How this is funded.
