The success of the JeNo 5.1" pushed us to develop a little brother, in 3 and 3.5" . This frame will therefore be as comfortable in Freestyle as in cinematic shooting . A 7" version of the JeNo also exists .
On a 5" or more, you may be tempted to keep an Action Cam, whereas on a compact and light machine, the DJI O3 reveals all its potential .
Designing a frame of this size ended up being trickier than expected:
Weight is crucial
Solidity and rigidity remain key points
The electronics are more exotic : 20x20 stack with separate FC and ESCs, straight or 45° AiO, fixing the stack in M2 or M3…
The low inertia of this format makes the O3 camera gyro very sensitive , the vibration tolerance is much lower than in 5"
A clear FOV : no spacer, frame, or propellers visible in the FPV return
After several iterations, we arrived at a first version of JeNo that ticks all these boxes! This is the 3" Classic version, unibody with a 4 mm bottom plate .
We weren't initially keen on the unibody, but this approach ultimately proved to be an excellent compromise . With a thickness of 4mm at the bottom plate, we obtain exceptional solidity and flight behavior worthy of a 5". Assembly remains easy and the absence of separate arms allows you to slide a 20x20 stack taking advantage of the 20 mm height of the bus.
Other versions are available:
3.5" (attention: props visible in the FPV stream)
3" Light
Separated arms
4": this is a variation produced by Kennytak and the necessary files are available on his page . The props remain slightly visible in the FPV stream. The JeNo 3 follows in the footsteps of its big brother: the front cage inclined at 25° allows for a clear FOV . Notches are provided to slide in any type of ND filter and the propellers are not visible in FPV feedback or HD recording.
Two types of camera plates are available to you: full carbon or soft-mounted . Knowing that to benefit from Gyroflow (or RockSteady) stabilization, it is imperative to opt for soft-mounted camera plates .
