Hi Rich. Built a bracket to mount it 90 deg from Renesis main CAS mount. Sorry I don’t have a photo. Tracy’s code incorporates it in the EC2. I mean there is at least a declaration in the code “BUSENSOR", but I haven’t checked the code to see if it was functional, just thought it was. I suppose I have always wondered about failure modes of the CAS. Of all failure modes I think the CAS is very low risk. I thought the weak link was the vulnerability of the wire feed itself to a broken belt etc. So Ive wondered about the point of a backup. Maybe just armour plate the signal from the one CAS. We had a Glasair III go down here in Perth - full electronic ignition on Lyc that was taken out by a belt breaking. He lost his engine, managed to put it down on a school oval but got terribly burnt.

(I’m sure I set BUSENSOR in the code) Sorry about the glare on the CRO screen. >> >> >> -- >> Homepage: http://www.flyrotary.com/ >> Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html > > > -- > Homepage: http://www.flyrotary.com/ > Archive and UnSub: http://mail.lancaironline.net:81/lists/flyrotary/List.html
