    I was working on the final design of some parts for our kit to fit Continental 550 engines today- crank sensor, mount and coil pack mounts. Andy Findlay who raced our system at Reno this year and Mark Frederick, who lent me a crankcase for measuring, have both been of great assistance. Some of the prototype parts should be ready to test fit by early next week.

    Some parts back from the CNC shop today. Hall sensor, sensor mount, fuel block and mount.

    Will test fit tomorrow on the case. If good, we'll do some production parts.

    Fitted the prototype parts up today. Will make a few tweaks to some parts. Should have production parts for sale by November.

    Looks good Ross.

    Am I to understand the magnets for the hall sensor are buried in the prop bolts?

    Yup, that's the easiest solution on the O-200 and IO-550 that I could see. You have 6 bolts so it's easy and accurate to drill the bolt tips for the magnets on four and 6 cylinder engines. We supply a split bushing to grab the bolt shank in a 3 jaw chuck to drill in a lathe.

    Would it be economical or convenient to offer those bolts already prepared in your kit, or is there too much variance between props?

    I haven't seen enough of these to know how many different types of prop bolts are used. I think MT uses studs rather than bolts.

    If people are stuck, they can send us their bolts and we'll drill them and mount their magnets. Same applies to O-200 engines.

    I think most people working on aircraft know someone with a lathe and then it's a 10 minute job to drill 3 or 4 bolts.

    Here's the setup in the lathe.

    That’s not too daunting :)

    Should have the documentation completed in a few days.
