Frame attuale — telaio temporaneo

Il drone monta attualmente il telaio vecchio (TBS Source One V5 7"). È in corso la progettazione di un nuovo telaio custom. Fino alla sua realizzazione, tutta la documentazione si riferisce al setup attuale.

Frame

Parameter	Value
Model	TBS Source One V5
Size	7"
Material	Carbon fiber, aluminum standoffs, M3 screws
FC mount	30.5×30.5mm (standard)

FC mount mismatch

The Pixhawk 6C and Raspberry Pi are too large for the standard 30.5×30.5mm mount. Both are mounted underneath the frame with a vibration damping system (rubber grommets). The frame has been raised ~8cm with extended legs to accommodate the new electronics stack.

Motors

Parameter	Value
Model	Emax ECO II 2807
KV	1300 KV
Count	4
Configuration	Props out

These motors are confirmed final — will not change with the new frame.

Propellers

Parameter	Value
Model	HQProp 7×3.5×3
Size	7"
Blades	3

These propellers are confirmed final — will not change with the new frame.

Battery

Battery upgrade in evaluation

Currently using 4S LiPo batteries. A custom 6S Li-ion pack is under evaluation. All electronics are rated for 6S — the current 4S setup might be temporary.

GPS placement

The GPS is mounted on a small carbon fiber rod, raised above the frame to reduce interference from other electronics. Secured with zip ties.

Previous setup

The drone previously used a Kakute H7 flight controller on the same frame. The Kakute H7 has been replaced by the Pixhawk 6C as part of the current setup upgrade.

TODO

Design and build new custom frame — the TBS Source One V5 is a temporary solution. The new frame must accommodate the Pixhawk 6C, Raspberry Pi 5, and all peripherals without the current workarounds (extended legs, underframe mounting). This is a major ongoing task.
Finalize battery choice — evaluate and build custom 6S Li-ion pack (Molicel P45B, 6S 1P)
Document vibration damping system in detail (grommet specs, mount design)
Document new frame design once complete
