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.

nice frame. great way to repurpose some 2203/4 motors and a vista :-) I dont fly it with a session, I have the higher kv version of the motors (3450) and use a 3s 1000mah and also 4s 1300mah (80% MOTOR limit) and its a great quad. I think if I didn't already have the 2203/4 motors, I would have preferred a 3" Toothfairy, though. Either way, if you are looking for a decent 4" frame, this is basically a mini "Prototype 5" frame.
I have wanted this frame for a long time. I thought it looked really cool and was impressed by its weight. But I was disappointed with it.
The frame comes without the press nuts installed. I tried installing them by screwing them on and destroyed almost all of the screws in the process. And didn't even manage to put them in all the way.
I had no idea how you were supposed to install them, as the frame comes without any instructions.
I tried to buy a new set of hardware for it, but FPVCycle was kind enough to send me another frame, and I ordered some high-quality Wera drivers this time, so I wouldn't mess up any more screws. But they also suggested pressing them instead of screwing the press nuts in. So I bought a bench vise, but it was destroying the carbon as I pressed, so I used locking pliers with a piece of aluminum on the other side of the carbon. I felt like this also damaged the carbon, because the threads on the press nuts are helical, not vertical. But they got in.
I don't like that there isn't any way to pass the motor wires around the vista and that they just hang outside the frame, and how the Nebula Pro camera just doesn't fit without using some kind of washers, and that the lens ends up sitting just outside the carbon protectors.
At the end of the assembly, I was surprised to realize that there isn't enough room to fit a capacitor inside the frame. I don't like to put the capacitor on the battery lead, and I don't accept the capacitor hanging outside the frame. But this was months after I first bought the frame, since I'm using overseas shipping, and I just wanted to fly it already. So I built it, and as I was switching the motor rotation directions, one of the FPVCycle 2203 motors started twitching. I was careful to check if the screws were not hitting the coils. The screws that come with the motors are too long for the arm thickness of this frame, but I managed to move the motor wires out of their way, so that wasn't the problem. I also did continuity tests but didn't find any shorts. I plugged in a lipo and it caught on fire.
At this point, I just grabbed everything and put it in my closet, and decided to build something else.
Decided to try and make a Fouride with the 5 inch arms are I’m glad I did. I’m running 2203.5s on 6s and with a 650mah it’s perfect. Flies so good and pretty durable so far. I dig it
I've built 3 smaller quads: Acrobrat, micro apex 4in and now the Fouride. I think this is the best flying out of all of them, of course it depends on the compnents you use. I built my Fouride with an H7 beast AIO and the fpvcycle 2203 2800kv motors on 6s with an 80% throttle limit. It flies way better than the micro apex and I think it's because of the weight. The 4in Apex is just a tad too heavy for 4in props imo
Nice well thought out frame.
