Description

The Happymodel OVX300 VTX is based on the Open source project OpenVTX powered by JyeSmith 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.

Reviews

OVX300

"Have not had much chance to fly, but did connect and power up and display out of the box without much fuss."

— Steve W. (5/5)

Light little strong vtx

"Great little VTX, at this point if it has a happy model name you can bet it will perform!"

— Reed C. (5/5)

Great signal small soldering pads

"Great signal small soldering pads but doable!"

— brad w. (5/5)

Great price

"Easy setup great signal"

— blake s. (5/5)

A Tiny Whoop Standard

"Excellent performane and penetration and it is lightweight. This is a must for whoop racers. I've purchased several and they've never given me any issue. My only complaint is the tiny solder pads. It definitely takes some skill to solder to."

— Wesley W. (5/5)

Great alternative for the TBS pro nano32

"Half the price. Same weight. Only downside is the tiny solder pads"

— Levi G. (5/5)

Top choice for micros

"The go-to vtx for micros. Obviously not for long range, so it’s perfectly acceptable for mid-range freestyle or even racing. Unbelievably low price is a big reason why I like it. The only negative is that it’s easy to bridge pads when soldering, but just double check with some sort of magnifier and that’s it"

— Kevin Y. (5/5)

My favorite Tiny Whoop VTX!

"My go to VTX for whoop racing, its cheap and works well! Highly recommended"

— Noah P. (5/5)

Quick shipping, I have flown

"Quick shipping, I have flown to far out with this vtx but so far it’s very stable."

— Jamie A. (5/5)

Killer lil' VTX

"This is a great 300mw VTX that performs better than advertised according to the IRC RF Power Meter. Setup and firmware upgrades are a breeze and it gives good range and penetration for 300mw. What more do you want from a VTX the size of a penny!"

— Joey W. (5/5)

Best analog whoop vtx.

"It just works. It works well, good range, easy setup, only downside is the solder pads are a bit small, but nothing impossible."

— Launie W. (5/5)

perferct on a babytooth

"This by far exceeded my expectations - i have this on a babytooth and it is fantastic"

— John T. (5/5)

Q&A

Will this work on a 5 inch build with Speedybee f405?
It would be a bit under powered for a 5" build but yes it will work. Just be careful of the input voltage. Use a bec to regulate the voltage going to the vtx as it is not meant for higher voltage.
