Foxeer Reaper 3.3GHz 4W 40CH (Tramp)

All specs and price from the maker's product page and the maker-hosted manual PDF, both fetched 2026-08-07; in stock at $69.90. Maker SKU MR1847. THE LIBRARY'S FIRST 3.3 GHz PART - the band had zero coverage. Published: 3170-3630 MHz over 5 bands x 8 channels, 9-36 V, 29.8 g, 50x34x14.5 mm, 20x20 M2 in two groups at 2.5 mm depth, Tramp, onboard FAN, and a 5 V output for the camera. rf_connector MMCX comes ONLY from the manual - the product page publishes no connector at all. Worth knowing as a standing research step for this maker: Foxeer's manuals carry spec lines the web page omits. tx_power_levels_mw records the five NUMBERED rungs. A PIT rung exists and is printed as a rung in the manual's own ladder, but it is deliberately NOT recorded as 0 mW: the manual says only "In PIT mode, VTx outpout extreme low power" (sic), an unquantified minimum, and writing 0 would fabricate a measurement. Note also that the lowest numbered rung is 250 mW - this part has no 25 mW setting at all, which is the licence-free level in most jurisdictions. power_draw_w 21 is COMPUTED from the published "Consumption: 2.1A/10V" and is the aggregate figure, not a per-level one; at 4 W out that is roughly 17 W dissipated as heat, which is what the fan is for. The camera BEC is published as 5 V with NO current rating, so only the voltage is known. size_classes declared 2026-08-07 as all five, not judged per class: nothing recorded about this part rules a size class out (Stephan, 2026-08-02 - declare all five, narrow only on evidence). Flagged estimated because it is that default, not a measurement.
