Fouride Blog containing recommendations on setups and more details!
Also, spare parts coming...
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 started out on a 5", but I found I didn't fly it very often since it was so loud and powerful, I required more space for it. So I moved down to the 3.5" and that was ok, but lacked the throttle response. Then when I tried the 4" Fouride, I fell in love. I can fly this thing in my front yard and in much bigger areas with plenty of throttle response (using 23mm 3450 motors). I loaded up MouseFPV's tune and it flies like butter. This really is perfect for me.
i was gifted this frame in the 4" size and never thought much about it..... had an extra aio and an extra vista so i went for it and put 2203 2800kv fpvcycle motors on it (4s) and man this thing is one of the most powerful and nimble quads i own..... it has become my go to for ripping around at home and even at new parks... this thing rips like nothing else i own.... makes me want to build the power pick 4" i was gited with the fouride..... what an amazing frame/build...
This was my first 4-inch build, wanting something that could be punchy but not cover a lot of ground since i fly mostly in the city. Easy to assemble, this was probably my 8th or 9th build, so not a ton of experience. Holds a 20x20 NBD stack snugly, had to use slightly longer M2s to mount it instead of what was in the kit. A really solid feeling compact build.
Super light weight solid frame. Had two 4" for a while and loved it before going a bit heavier 5" setup.
Let me tell you, I built this thing using two analog board stacks and everything fits perfectly. Definitely not a beginner build, but the design is truly refined! I still fly a Hero session and the 3450Kv motors on 4S. It's really made me wonder if I need to sell all my 5" quads and just move to 4 inch!
