Description

The Happymodel OVX303 VTX is based on the Open source project OpenVTX powered by Jye Smith from the EpxressLRS team. Open VTX aims to provide firmware with both the SmartAudio and Tramp protocols. Either protocol can be used on the flight controller and on VTx power up the protocol used is automatically detected by OpenVTx.

Awesome analog vtx

"Super small and light, the ad is incorrect, it's actually 400mw. I paired it with a Truerc core lhcp antenna and the range and penetration is pretty good. I sit in my garage right next to a metal door and I fly all around trees on my lot and have no problems, except for one spot where the signal has to go through two trees and a metal garage door. For less than 13 dollars in 2023 you can't complain."
