TorqueFPV Hornet HD 3"

Hey folks! My first rotorbuilds post... People have been asking for pics of my Hornet 3" build to see how I have my caps installed. Those are 2 16v 220uf low esr FR series caps. They're needed to suppress voltage spikes from freezing out the DJI FPV feed.

AUW is 159g with the Tattu lipos and runtime is up to 3:00.

Here's the vlog going over why this build is special for me -

Does this frame use M2 or M3 hardware? Does it come with the necessary hardware? If not, what did you use?

m2 and it comes with it!

is the cap on your fc necessarry? it seemed like you already have a cap on your xt30 connector

It might not be necessary but additional protection and voltage smoothing can only help.

The 2 caps are specifically because I had a video freeze with 1 25v 330uf cap on the vista (and the included cap on the pigtail). The DJI system is very vulnerable to voltage spikes. So in my case the 3 caps are needed but you could probably get away with the included cap plus a single bigger low esr cap on the esc and or vista.

Do you know how to use the T6/R6 pads? I'd really like to build this with GPS on the third UART. I don't understand why it doesn't show in the Ports tab. Thanks for the help.

Strange it also shows 2 tx2 pads

SOLVED! There's a BetaFPV article titled "How to Enable UART6", but you have to change the second command to "resource SERIAL_RX 11 B10". I'm putting GPS on this bad boy.

Thank God! I have been wrestling with this as a noob for a week. Hopefully this will solve my missing OSD and low power issues.

What quad antenna would you recommend for someone who isn't using crossfire? I use a dji radio. Thanks!

ah in that case even the whip antenna would be fine or the stock vista antenna.

I already ordered a couple of parts for my build and then I find out they don't ship this frame internationally. :(
Do you guys know of a similar frame?

I've had this frame pre-ordered since the moment TorqueFPV made it available... your posts just get me more pumped! Clean build 👍

Amazong it hasnt even a year into digital fpv and we already have stuff this small. Great build!

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
