Hi eveyone,
I took my DIY timer jig to the club meeting last night and it worked as expected :-)
I am still concerned about fusing, and how to prevent a burnout if the motor is stalled.

Ricky mentioned a requirement in the UK for some sort of inertia switch. Can anyone shed some light on how to create such a thing?
The only one I know is of the mechanical variety on the KP01, which Ricky says is not made in that form any more. That type of arrangement seems a great candidate for 3d printing - but for now I'm interested in a DIY electrical inertia switch that would work for a variety of model size if anyone has some ideas?

thanks
Mike

Not sure if you are talking scale or duration. Mike Smith flies big electric scale models and uses a simple fore-aft  swinging pendulum, lightly held back (I think) by a small magnet to make the circuit. A sudden deceleration sends it forward, breaking the circuit, and it sticks to a stronger magnet so it can't start up again

Thanks Bill, scale is what I'm looking at. I'll contact Mike.
