FR7

My first 7" build, the FR7 is an amazing open source design by Jeremy Mariscal. Flying 4400 5S (dual 2200s) with 2408.5 1922kv motors, this quad is designed to be a strong, fast, cinematic mountain surfer. The FR7 is one of the coolest designs I have seen. Now that I've got some nice build and glamour photos, next will be to test, tune & send it. I will update this build with video from this bird soon.

Can I just ask what kind of antenna you have used to connect the immortal t in the front? Looking at the frame and the platypuss diversity mount it seems the standard 120mm length will not be enough.
P.S. just an awesome build!!!!

I have a question :p)
How do you do for multicolors TPU parts ? Do you have a bi extruder printer, or you just change filament for each color ?
Thanks

Great Build.  I just purchased mine and getting ready to build.  I noticed u r using tbs nano diversity, how did u get the antenna extended?

ddckl   Sep 01, 2019  

How did you extend the immortal T to reach the diversity rx?
Do you have pids for BF 4.0.x ?
Thanks in advance I'm building mine now 😁

jazzyboy   Aug 12, 2019  

Great job for this build.
What is the red long straight antenna on the rear (near the Lumenier AX-ii) ?
Thanks

Great looking build. Are you using 2 immortal Ts? Unclear what's inside the orange straw. Thanks. What range and fight times are you getting?

What would you estimate is price for carbon as sheet material?

WILLBEER   Jun 23, 2019 

No clue

wow, such a beautiful frame and build. I am also interested in 6 inch. I wonder if you could share just the weight of frame? btw, is there a place to order this to be cut? thanks.

Thank you so much for the info.

How's the stiffness on the actual frame? It sounds good from the video, but I've had a few frames cut from CNCM and was a little disappointed in the carbon

WILLBEER   Jun 14, 2019 

The arms are 6mm and frame seems very stiff.

What's the big red antenna tube? Also, what an amazing build!

WILLBEER   Jun 13, 2019 

Thanks! It's got the active element of stock crossfire dipole inside tube, with ground element balled up inside tpu print.

Thank you, that is really nice to hear. I am glad that you appreciate the build and photography, I am passionate about both.

coming from an Avionics background, its nice to see soldering that isn't over cooked and wiring routed properly. it just makes my brain feel nice.
If only I could pull it off too...

WILLBEER   Jun 09, 2019 

I couldn't do this at first but I have gotten much better.

Love the build! Cleanest I've seen for a 7"!

Do you know if there is a 6" version available? Are props in view of the GoPro footage?

WILLBEER   Jun 09, 2019

There is not a 6" version of this frame but you could always just run 6" props on it. No props in view.

QuadX, check my FR7 for example footage with a Session in superview, no props in view

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..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
