I'm at least glad that people like Corbin and Matt have embraced the "Quirky" lifestyle. Makes me sad to see high time Qs like this one passing through a growing trail of new owners unflown...

Re: Coughlin Brake Mount Drawings
Michael Dunning
HOLY SPUMONI, BATMAN! Don Coughlin was a freakin' genius!
Once assembled, this new version fits inside the mounts I currently have. Since the mounting hardware is identical, the difference in weight will be between the wood becoming aluminum and everything else shown in the other version (and those slides are 3/8 stainless steel). There appears to be an error in the .375 diameter call out for the "Outside Bracket" (no idea why though) so I'm glad I committed to a mock-up first. I created a new photo album with the results to save everyone's bandwidth: Coughlin Brakes for #2827 Also included are some pictures of the unfinished foam edge I mentioned earlier that I will need help tackling next. Part of my concern in how to proceed is that some of the edge looks like the wood from LG9... -- -MD #2827 (still thinking about planning on visualizing how to finish building)

The ad didn't have any photos or an n number listed, but based on the description, I am pretty sure it is Paul's plane. Sent from my Verizon Wireless 4G LTE DROID "John Hoxie via groups.io" <hoxdesigns@...> wrote: Paul Spackman's N # is/ was N131PS.

Re: Jabiru Q2 on Barnstormers
I think this is Paul Spackman’s airplane. He sold it last year to a guy in Arizona. I don’t think that it has flown since he took it back there.

Just saw this ad posted and came up empty trying to search the owner's name on the Q-List and quickheads. Looks like we can chalk another one up to the "successfully flying behind a Jabiru" crowd:

The pickup for the Electroair needs 500 ohms to check “good”. Ohm it out. This may be apples to oranges though. Different company.

Re: Electronic Ignition Install - No Spark from Coils
Thanks, everyone.
I will answer the questions and some thoughts in this reply and then again as more come in. Yes, it is a Hall sensor. Looks as though most are thinking like us and that it is something with the magnet sensor alignment/distance so we will check that first. It is also possible we didn't rock the prop fast enough at #1 TDC....very likely as well. We will test pins 1 and 9 again...just in case we counted wrong. Good idea on passing a magnet over it and good to not to connect a VOM. Thanks!! As always, appreciate everyone's quick input! -- Corbin N33QR

Continuity testing a Hall device with a VOM will destroy it instantly. Just in case you were considering it.

No spark so we are troubleshooting as best we can including reviewing the instructions for any missed steps. Power from the battery to the circuit breakers is good and the signal coming back to the warning lights is good (if one coil fails a light comes on, etc.). However, we are not registering any power getting to the coils and have triple checked the wiring is connected to the ignition boxes going to the coils. Could it be that the magnet sensor is not sending a signal back to the ignition boxes therefore no spark? We wonder if there is a bad connection in one of the magnet sensors. The other area I thought it could be is that we are bypassing the keyed ignition for now. My avionics guy assured me that it is not an area of concern since the way it is currently wired, it is not an open-loop (key in off position). I still wonder though... If anyone has any known common failure points please let me know. We may try and go back out to the hangar this evening. -- Corbin N33QR

Re: Electronic Ignition Install - No Spark from Coils

It is a hall sensor. I once replaced one which was sheared off by the magnet.

A hall sensor measures presence of a magnetic field (or not). A simple magnetic sensor (coil) will see a “double” peak as the magnet passes. Not sure which type of sensor Klaus is using, but I suspect it is a hall sensor.

I just went through the same issue on my Cozy installation. Everything checked out but still no sparks. Eventually traced it to the mini-sensor not being correctly aligned to the trigger ring. Aligned both in distance from and vertical to it.
Question; can you get a spark by passing a magnet (South Pole) over the mini sensor?

Re: Beginning labor pains

As you are planning inboard land gear, the strength required at the tip of the canard is much reduced. With the gear at the ends of the canard I would not touch a repaired spar under any circumstances. There might be wiggle room in your configuration. I am not qualified to address that.

Re: Electronic Ignition Install - No Spark from Coils
Not sure if Klaus uses Hall sensors or not, or if it even matters, but there may be a high pass filter on the input from the sensor, that effectively blocks the signal if the magnet does not move past the sensor fast enough. This could be a safety feature to prevent the engine from firing when RPM is below a certain speed. I am just guessing here, but the board that he has in the system is certainly capable of doing this if he wanted to, and it would be a smart thing to do to prevent the engine from kicking back. To test this, you could disable your fuel system, hook an automotive timing strobe to your coil output and then crank the starter to watch the strobe to see if you are getting firing pulses. My uninformed 2-cents worth….
