It’s very unfortunate that FuriousFPV has discovered a hardware design flaw in their popular True-D V3 module. If you’ve already bought this receiver module, you can follow this tutorial to fix it. Furious has promised to fix this in any future module they sell.
Update (Feb 2018): FuriousFPV confirmed that the issue has been fixed in all units of True-D V3.5, V3.6 and onward.
What’s the Problem?
According to FuriousFPV, there seems to be a potential issue of short circuit if the module is pressed too hard. They quickly identified the issue and came up with a solution. They said it has only affected a few units out of 5000 they have already shipped out so far. Anyway, to be safe it’s recommended to carry out this fix if you’ve already owned the True-D V3.
The detail of the hardware bug and causes was covered in the official announcement on Facebook, here is a copy:
IMPORTANT NOTICE: To our True-D V3 owners:
We are getting feedback from customers that there are a few incidents that some customers got issue that when plugging the battery in, both our True-D V3 and their FatShark goggle stop working.
After trouble shooting last 2 days to find the root cause of the problem, we have come to conclusion that due to unfortunate external force to the top module panel, the header on the top module panel may touch the bottom module panel and causes short circuit between the 5V and GND of the True-D V3 module and in turns damages the LDO component on the FatShark goggle.
These incidents are very rare, considering just a few cases over total 5,000 True-D V3 units shipped. We are very sorry for the unfortunate incident and we immediately make new plastic spacers to isolate the top and bottom module panel so there is no possible short in the future. We will ship the plastic spacers next week to all customers and dealers worldwide.
For people who has issue with their fatshark, it is just a very simple LDO replacement that can be quickly fixed in a few minutes. Please send email to [email protected] if you have issues and we will assign designated dealers for you to send back the goggle for us to get it fixed or we will send you a new LDO for you to replace it. For the True-D V3, it is just shut down when it has short circuit and we will replace for you a new True-D unit.
Again we are very sorry for the inconvenience caused and we assure to you that these rare incidents are very isolated issues and we will do our best to get you back to flying.
Thank you for your understanding and support. Sorry for the delay in replying to the inquiries because we want to make sure we found the root cause before we make announcement.

How To Fix True-D V3 Module Issue
FuriousFPV came up with some 3D printed parts, basically just spacers, to be put between the top and bottom module panels.
Any current True-D owners should be able to get the 3D printed parts from the resellers they bought their module from. If your True-D has been damaged due to this problem, you can contact FuriousFPV to arrange a repair ([email protected]). If you have access to 3d printers, here is the file to print.
Here is a tutorial by Santiago Espindola how he fixed his. Santiago suggests any material should be fine, including normal PLA. But heat resistant material is preferred such as Nylon.
New v3.1 firmware
On a unrelated topics. a V3.1 firmware was released 2 weeks ago if you haven’t already flashed it. Some bugs were fixed, and improvement on performance were made.
- Add L-Band to be compatible with new VTXs
- It can save all 8 channels
- It can use all letters from A-Z to set name in define channel (NEW_F)
- The firmware V3.0 has some small bugs in switching calculations that may cause signal stall at some rare occasions.
Firmware can be downloaded on www.furiousfpv.com under Download tab
Here is a tutorial how to upgrade firmware on the True-D.
Is this an issue with V1? Ive been getting random black screen, about 3 months after I dropped my Dominators. Guy told me it was common with V1s and said I should get the dvr module with 2017 date (mine is 2015), and receiver/hdmi module. Or is the issue more likely my True D module after falling where it popped out of the goggles?
Yea only with the old version, all new versions don’t have this issue.
Anyone hear of someone with a True-D v2 unit that burned out their Fatsharks? Just happened this weekend after 7 months of no issues.
I was between packs and then plugged the goggles in and got a black screen. Tried another Rx, same black screen. Removed module and powered on FS to enter replay mode… black screen.
The back of the True-D unit looks like some plastic between GND and Audio pins got melted a little.
no i think the only recognised issue was the V3. might be worth contacting Furious about it.
Well, mine had the spacer in it and it STILL fried my goggles and itself. Furious is taking their SweetA** time on getting back to me. Grrr.
Hi,my name is Sanny Odulio;I’m in lakeforest Ca.
I just purchased a unit and was concerned about this issue happning to my V3. I don’t have a 3d printer to make this spacer,can you direct me to a local shop to attain this item,or send me a set to install? Before I go and install this unit in to my v3. Also the fitment of the cover is not too good, as it don’t snap.all the way in,and has a gap between the V3 and the cover. What would be the fix for this issue?
Note that V3 release date is 20 March 2017. Does anyone know if spacers will be required or is the fix built in to new release?
Spacers should be included in the module according to Furious.
It would be cool if there was a date somewhere for your articles s…maybe I’m missing it, apologies if so.
