9" Long Range Budget Build

I spec-ed out this build with low cost being a big focus. But didn't want to skimp out on the long range VTX or receiver. (since ultimately not loosing my drone would justify spending a little more on these 2 parts).

This drone is going to be used for cinematography flying over rivers and marsh, so GPS rescue is a must. I have gotten flight times of 15 minuntes so far using ZOP Power 22.2V 8000MAH 30C 6S Lipo (Weight: 920g). More updates to come if this build gains any popularity.

Also if anyone has a more efficient motor they would suggest for this built I'd love to hear about it.

Just out of curiosity why are you using such a bigmotor? I just bought one of these frames to use the gear off of my old TBS discovery clone. With the discovery clone I could get 15 minutes on a 4s 5200mah multistar. I think the weight and amp draw of those motors are whats hurting your flight time. Unless youre trying to do some acro also and need the power. With my 1kg ish Discovery clone I was running 2212 980kv sunnysky motors. Im sure there are better motors then those now but I think going with a smaller motor would help.

I've just switched to the Racerstar AirB 2514 1498KV motors. I haven't done any testing yet with them.

Great build! Does it needs to be 6s? I think you would be better off with those motors [£33.32]4X Racerstar 2508 BR2508S Green Edition 1275KV 4-6S Brushless Motor For FPV Racing RC Drone RC Parts from Toys Hobbies and Robot on banggood.com

or those more expensive motors

and 4s as you would save 200gr weight on motors and have similar thrust.
Do you get oscilations with those thin for that lenght 4mm arms?

I haven't noticed any oscillation issues with these arms. I have been looking at upgrading to these motors(linked below) and saving the 3508 for a bigger build.

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..
