I have been trying to think of a comment to add to this thread.
I canít think of anything to say, it is that good.

Excellent  :praise2:  :praise2:  :wine1:

Are you planning an alternative ignition system for the first trials?
Best regards

Thanks for all your kind comments guys and thank you to all those who are following along quietly in the background.  :ThumbsUp: :ThumbsUp: :ThumbsUp:

Roger, my thoughts are to use one of the magnetos as a distributor (centre terminal connected to the coil) rather than hope for a working 1/4 scale magneto. The magnets and Hall sensor are already built into the magneto units.

They started the full size engines in a similar way. The pilot hand cranked a starter magneto in the cockpit. this provided the sparks to fire the engine. The engine mounted magnetos only turned fast enough to produce sparks when the engine was running and up to speed.

Stay safe,

Mike
