FPVCycle Fouride Frame- Vista Compatible (Choose Size)

It was just a really nice frame (I got the 5" one) and looked unique but also well made. Its a true ____ to put together (a very complex design) and required a bit of sanding on the central standoff hole, but all in all a sensationally well made frame. Carbon is all chamfered too contrary to the pictures showing it to be straight. Would recommend if you are at least an intermediate builder.

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.

I've built a second one after crashing the first into a lake. Both were using the 5" arms.
I love how light and short this frame is, but that it still comfortably fits all of the electronics. You can even fit a 1000uf 35V capacitor between the Vista and the AIO if you remove the middle standoff. You can mount two of the vista screws upside down with the nuts on top so that they will perform a similar function as the removed standoff. It's also a good idea to put some plastic M2 nuts on the tip of the center arm screws since they stick up a little from the press nuts, so they won't damage the capacitor.
I've mounted the vista on the front on my previous build and on the back on my latest one. I prefer the AIO on the back so you can route the battery lead through the back of the frame instead of the side. I've made a very short lead with the XT60 barely coming out of the frame, so I didn't even have to retain the battery cable like I do now underneath the battery strap.
I didn't like how the motor wires hanged loose on the side of the vista, but on my latest build I've used a zip tie around the Vista and the bottom plate with the motor wires pressed on the side of the Vista, so now I am much more confident that they won't flap with the wind potentially causing vibrations in the AIO or being chopped by the props. I've also used a second ziptie to secure the motor wires to the bottom plate in the middle of the frame, which I could now do since I removed the middle standoff.
Make sure you purchase the back TPU antenna mount with the frame, and the long 15cm Caddx antenna. I've tried using the short one with the side TPU antenna holder, but got very short range since I was using a big 6S battery that blocked the signal.
I run this on 6S 1100mah. I used to have the 4S 23mm Short FPVCycle motors with a 70% motor output limit on my previous build, and could get a little over 12 min of cruising and about 5 min of very hard flying with long throttle punches on open fields and lakes. It turned out weighing 220g with the FPVCycle motors, plus 200g for the 6S batteries. It performed great.

Bought the Fouride frame. My first 4" quad. Space is tight but with good planning it can be great. I just used the recommendations Bob put out and it is great. Light and flies great.

Love the 5" Fouride with 2203 3000KV combination. Smooth, low noise, efficient and great flying. Big thumbs up.

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.

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!

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.

Perfect : durable, quite light and easy to assemble. I recommend this frame!

I really like the way this frame is designed. Plenty of room and good distribution for the electronics. It appears to be durable but time will tell. I’m going to order the 5” arms in case I get curious to try this on 5” props. Give it a go if your looking for a 4” to carry a vista well.
