SparroXs

I wanted to check out two things.
A stretched-X quad vs a true-X quad and the Racerstar BR 1507 - 3600 kV vs the HGLRC Flame 1407 - 3600 kV motors .
So I build two identical quads with the oh so sexy GEPRC Sparrow frame. The purple one is the stretched-X and the green one is the true-X.
I prefered the strechted-X and crashed the true-X (green) against a tree and replaced it for a stretched-X bottom.
A stretched-X flies much better in turns and is more stable on straight ends.
The difference between the Racerstar BR 1507 - 3600 kV vs the HGLRC Flame 1407 - 3600 kV motors was not noticable, they both perform great.
The GEPRC Sparrow frame not only offers lot's of space but also very good camera protection and the aluminum cage is very strong.

How do you find the Quelima Mini cam? Seen these on a few builds and wondered how they compare to a GoPro? :D

Well, you can't really compare them. The SQ12 is a $ 13,- camera, but for the money and taken into consideration, that one crashes, it's not bad for the money. In the parts list is the url to get one. Tou can check this video out to see how the quality is.

I started to think that I prefer stretched X frames but of course, I am too lazy/bored to do a comparison like you did. Thanks!
Now, I actually suspect that it's more about distance between motors than true vs stretch configuration. How would it fly if you increased width along with the length keeping it true X? Take the Acrobrat, for example, which is a true (I thought it was a stretch) but it's a huge frame for 3-incher. It's so stable and controllable. So it would be interesting to find a frame with both 3 and 4 inch replaceable arms and see what effect the size has. I know, I know bigger is better 🤭 but in this case it could be scientifically proven!

Some buy a 6" frame and fly it with 5" props. I think all frame forms fly different, for example an H-frame or a deadcat. But I like the streched X's, you instantly notice the difference. I just got a super stretched X in today.

I am planning next 3" build on a 4" frame. Yes, 3" props on the 160mm frame is the same idea

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..
