I am working with AKK on a new VTX – the OBVTX (Oscar’s Backpack VTX). It has some unique features and can be mounted on the back of a micro FPV camera, hence the name “backpack”.
Buyer’s Guide: How to choose VTX?
Update (23 Sep 2018) – Problem with Standoffs
There is an issue with the supplied standoffs – they are too big to fit the Runcam cameras. I brought up the issue with AKK before the official release, but they released it anyway without actually addressing the issue.
I am truly sorry for those who are affected by this problem. I have asked AKK for a solution and how to compensate those who are affected. If you want to buy this VTX and intend to mount it behind the FPV camera, please hold off for now. I will update again when the issue is resolved.
Update (July 2019) – Avoid AKK
AKK removed my name on this VTX quietly, which means they don’t want to give me any credit for the work I’ve done on this VTX.
Also they keep ignoring my request to address the issues with the wrong standoffs provided with the VTX.
What can I say… Avoid them at all cost.
Where to Buy?
The Oscar’s Backpack VTX will be available end of August, you can pre-order it now from AKK.

What’s Special about the OBVTX?
I am always searching for the ideal VTX, there are some really good options on the market, but something is missing. I told AKK about my “ideal VTX” and they decided to make a product based on the features and specs I want.
I have been testing and helping AKK to develop the OBVTX for over 4 months, and I cannot wait to share it with you guys.
The OBVTX is not the first VTX that can be mounted on the back of a camera, but there are something unique about it.
Features and Specs
- VTX Control using SmartAudio
- Built-in Mic
- MMCX Connector
- 5V Input
- 25mW and 200mW Switchable Power
- Solder pads
The unit I have is just a prototype, it doesn’t reflect the the build quality in the final version.
There are two holes for mounting on the back of a micro FPV camera with screws and 3mm standoffs provided. Because of the tiny form factor, you can also mount it anywhere in the mini quad you see fit :)
The mounting holes are perfectly compatible with Runcam’s cameras, but because Foxeer’s have slightly smaller mounting pattern, you might have to push the standoffs inward to get it to fit. (though I need to verify when I get the final version)
Due to the limited space, AKK is using the same LED indicator design as their Nano2, which I personally find quite confusing when changing settings. But if you are only using SmartAudio it’s not a problem at all.
It has a robust MMCX connector, and a built-in microphone for audio. At first AKK told me it was impossible to fit a Mic in there, but they managed it in the end so kudo to them! We also spent a few weeks on audio quality and it has been improved considerably from the first prototype.
I used the OBVTX when I was testing the Rapidfire, take a look at the performance.
I haven’t even got the production version myself (only prototypes). But I will test this VTX like I normally do when it arrives.
