Avionics Standard: ExpressLRS 3.x & Betaflight 4.4 Reference Baseline

Editorial Policy

Source use

Specifications come from seller listings and applicable documentation. We label claims as seller-advertised or documented and do not present unverified specs as measured performance.

Three-level evidence structure

Seller claim
What the listing says about a component.
Applicable documentation
Manufacturer or protocol information that supports or limits the claim.
Editorial question
What remains unclear, conflicting, or unverified for the buyer.

Listing audit standard

Our editorial standard is to check protocol compatibility, mounting patterns, clearance dimensions, and replacement-cost notes where listings provide them. Missing or conflicting details are marked unknown instead of filled in.

Corrections

When a listing, document, or our wording changes, we update the affected page and note the change. We do not claim a formal review cycle, response time, or dedicated support channel.
