G Aman kolb MK-3 2200 I'm not flying my CH601XL yet but I second that suggestion. I went with an aircraft type key switch "Off, Right, Left, Both, Start" from ACS but if I were doing it again, I would use two toggle switches for the right and left mag and a start button. One obvious benefit is that when you are doing maintenance or daignostics, you can spin the engine with the starter while the mag switches are off. The key won't allow that.

Since it didn't require a key, in order to provide some security there was a mic jack labelled COM3 inline with the starter. You had to insert a mic plug that had its tip and ring shorted to provide a connection for the starter. When you removed this plug the plane wouldn't start. Made it very difficult to steal. :-) Craig -----Original Message----- From: owner-jabiruengine-list-server@matronics.com [mailto:owner-jabiruengine-list-server@matronics.com] On Behalf Of gary aman Sent: Tuesday, August 21, 2007 8:31 AM Subject: Re: JabiruEngine-List: Re: Key Switch for JAB 3300 The security the switch gives is its best feature.You can easily wire from the master a second lead to a push button tied to the starter energize terminal.

My key switch will of course provide the anti-theft protection since without it, the mags can't be turned on. I may use your shorted out 1/4" male mono plug as a more permanent way to activate the starter solenoid with the mags switched off. I didn't like the idea of a permanently installed second starter switch because of the likelihood of activating it accidently. The extra jack labeled "Starter" could not be activated without having the shorted out plug inserted. That's enough safety for me, and as I said, it doesn't have to be camouflaged with a misleading label for security in my case.

It sure fooled the mechanics when I didn't leave the keys in the airplane but instead handed them to them. I got more than one call (from the same guy each time) telling me they had a problem they couldn't figure out ... The plane wasn't starting no matter what they tried. :-) Craig -----Original Message----- From: owner-jabiruengine-list-server@matronics.com [mailto:owner-jabiruengine-list-server@matronics.com] On Behalf Of dredmoody@cox.net Sent: Tuesday, August 21, 2007 10:57 AM Subject: RE: JabiruEngine-List: Re: Key Switch for JAB 3300 Thanks Craig, you have given me a good idea there.

I've looked at the Drawing Rob refers to, and I think it's wrong. It's ambiguous the way it's drawn, showing the connection through the oil pump output port, and down into the gallery, when in fact the connection should stop at the (upper) pump output port. I'll clarify with Jabiru and will post here if different. However, I've measured the pressure at both points, and the lower port is definitely at a lower pressure, consistent with it being after the cooler and filter. I note that the drawing isn't included in the later manual version for hydraulic lifters!

Very boring and tedious adding and taking 2mm screws, nuts and washers I could only do it for an hour at a time. Any draft in the house and the prop would move. When it was perfect and soon after in flight I got a very bad scary low frequency vibration when decelerating and turning left at about 140KTS.Maybe precession triggered it off. Reducing throttle did not immediately help. I got the set up dynamically balanced and it took a 3/4X 7/16" bolt with nut and two washers to correct the dynamic balance. I had been very satisfied with the engine running but it ran smoother than ever before when the first weight was fitted. The difference was very obvious. The prop/spinner and backing plate are now NO WAY in static balance. I have marked the parts and the prop shaft. The job took 4/4 hour and was done in the hangar. It means that it was my engine that was badly out of balance and is now corrected by the dynamic balancing of the prop/backing plate. It means that if flywheel bolts are breaking it could be due to a poorly balanced engine. My 3300 engine was factory rebuilt to zero hours in 2006. Based on my experience I would recommend that all users get a proper dynamic balance, making sure that the backing plate and spinner are in good sound condition at the same time. I understand that Pete and some others have got the equipment to do the job.
