The squeal noise always happens immediately prior and I don't know what the sound is.
Luckily it's tough and nothing breaks so far except a carbon boom but I need to fix this bug.
Any help appreciated,
My first port of call would be checking the gears can't slip off the pinion, that could be what the squeal noise may be and it should be a simple fix...just push the gear further onto the carbon rod so it can't slip.
