Title: Starling 2 Max – Flight Performance at 2,800–3,000 m Above Sea Level Hello ModalAI Engineering Team, We are evaluating the Starling 2 Max for research flights inside rose greenhouses in Tabacundo, Ecuador, at approximately 2,800–3,000 meters above sea level. Before purchasing the aircraft, we need to assess whether this operating environment falls within its safe flight-performance limits. Could you please clarify: What is the maximum recommended operating altitude above mean sea level for the Starling 2 Max? Has flight performance been tested or characterized at approximately 3,000 meters above sea level? What reduction in thrust margin or flight endurance should we expect at this altitude? Are there recommended limits for payload, battery configuration, ambient temperature, or mission duration under these conditions? Does ModalAI provide performance curves or engineering data that could help us evaluate this operating scenario? Are there any special safety precautions or configuration changes recommended for high-altitude operation? Our primary concern is maintaining adequate thrust margin and safe, repeatable flight performance inside a confined greenhouse environment. We would appreciate any relevant documentation or test data. Thank you. FloraVision AI Engineering Team Ecuador

@chiu-pk The LED status is good, this receiver should be recoverable assuming the wiring is correct. Could the M0184 firmware update have caused the receiver to lose its previous binding/configuration? Yes some updates will unbind the receiver. If you want to put the receiver back in bind mode and voxl-elrs doesn't work, hold the button for 5 seconds and it should enter bind mode indicated by the led status rapid double blink Is it expected that voxl-elrs ping gets no response while the receiver is waiting for binding? voxl-elrs ping should work in both cases, but to be sure try to bind and see if it works Is there a recommended recovery/reflash or reconfiguration procedure for the M0184 in this situation? Try to get voxl-elrs working if possible, if not then using the expresslrs configurator pointed to our custom fork of ELRS with a USB serial adapter that supports 420000 baud will allow you to update https://docs.modalai.com/elrs-configurator/
