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.

Evidence

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

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
