I decided to do a few pre-emptive mods to my MMM.
- Removed switch
- Wired for external BEC
- Re-routed fan wire outside of the case to stop it rubbing and added some shrink
- Enlarged RX cable opening
- Removed top of fan cowl
- Added a 2200uf 35v cap
- Removed the centre of the base and added a lower plate to increase PCB clearance.
- Mounted on foam and soft velcro
PS the switch was cleaned up from here and just bridged on the PCB in the end...
