This frame was designed as a 4” platform but then pulled out to 5” because it would support it nicely. It’s really intended for 4” but it’s quite nice as a very light 5” platform as well. The 5” version is discouraged for beginners because it is not as durable.
The Fouride is intended to be used with analog video or the DJI/Caddx Vista system with the regular full size DJI camera (Nebula, nano and micro size cameras fit as well). It’s a low weight platform which takes advantage of the current and future line of electronics. The layout of the frame consists of two side by side stack platforms that fit both 20x20 and Toothpick/whoop boards with a low 15mm build height. This low build height is intended to keep the weight distribution tight.
In designing the setup around the current and future micro electronics, we discovered an annoying design limitation. The most obvious design layout would be to stack all the electronics. The dilemma there is that either the battery is slung under the frame or hoisted way up in the air above the electronics. Neither of which is preferred for flight performance (racers excluded). The other slightly less obvious option is to spread out the electronics side by side. This allows for a really nice and tight weight distribution and CG, but results in a fuselage that's a bit longer than desired. So we went with 4” arms rather than a 3" because it just makes more sense.
With 4” props, you barely see the tips of the blades in the DJI camera. With 3” props, you don’t see the blades at all. There is a mounting platform for a GoPro on top which is the same platform as the CineGlide and CineSplore as well.

I've been bashing around my 5" Fouride for a few weeks and it's been fantastic. I used the recommended parts and it has become my main quad. It's fast, powerful, simple, and very durable. The 2203 motors do quite well with the 5125 props and a GoPro Session 5. Like Bob said, it may not be durable enough for a beginner, but it's still impressive.
This frame is very well thought out and serves its purpose incredibly well. It's actually the first sub 5 inch quad that I can honestly say carries a Hero 5 session as well as a 5 inch. I can only imagine how the flight performance and flight time would be with something like an insta 360 go, or even the new gopro lite trend we are starting to see. However, there is one downside which is shared among the other frames offered here which I am hoping Bob will address soon. We need to have spare parts available, individually for these quads. The reality is that regardless of frame durability everything that crashes will eventually break. Having a full list of available parts which can be sold as needed and purchased individually would put every frame on this website above 5 stars in my opinion. However having to purchase an entire frame for what would be a 2 or 3 dollar part is unfortunate.
