The 2Fiddy frame was designed to be simple yet durable, so we tested and simulated a variety of carbon thicknesses, component layouts, and fasteners. We knew that simply scaling down a 5" frame may introduce frame resonance, and that will certainly affect performance. Although some resonance and vibrations can be smoothed out by firmware features, I believe that great frames shouldn't require special filtering to run smoothly.
Arms are locked in place by two bolts and use press nuts for both ease of use and to keep the attachment locations as low profile as possible. No arm mounting hardware is shared with any electronics and the arms meet at the middle for a unibody-like stiffness. These arms were not only tuned for reduced resonance, and ease of replacement, but are also made to be as durable as possible without causing a break elsewhere on the frame.
One of the most unique features of this frame is it’s versatility for mounting your FC/ESC. We recommend the use of AIO flight controllers to save weight, but didn’t want to limit people to one layout. The 2Fiddy has holes for 30.5x30.5, 20x20, and whoop style layouts. And although we recommend running an AIO board, you can even run a dual FC/ESC stack by simply flipping the arms under the bottom plate and using the included 20mm standoffs.
While the frame was designed specifically around the Caddx Vista FPV system, analog FPV gear will work just fine. The rear section has 20x20 mounting holes that line up with the vista unit, and the top plate has a little notch to keep your antenna centered along the rear standoff. This design allows you to simply use a zip tie to mount your antenna without the need for a 3d printed part. The front camera cage is spaced for a 20mm DJI camera, however smaller 19mm micro analog cameras work just fine. There are double slotted mounting holes for the DJI camera as well as a dedicated center hole for cameras such as the Nebula Pro HD, which provides 0-35 degrees of tilt. The cam cage features an innovative plate-lock design that ensures maximum camera protection, while ensuring that the cage won't pop-out in a crash.

Although I do my best to complete this library, you may not find the model you are looking for.
In this case, do not hesitate to ask me to add it : You're not bothering me. Please be patient, depending on my workload, I may take a few days to work on your model and gather information.
I'm sometime asked to add a non flying model to this library but unfortunately, it's not the focus of this website
