Your ignition module is providing 2 pulses per revolution (see page 43 of Plasma II/III installation manual).  You would need to set the tach display for that.  Probably it has been set by default to 1/rev in which case it is reading double.  Your 2500 RPM is really 1250.  And then you will have it.

The tach was reading 2500 which is more than my RPM at rotation.  It felt closer to 1000 RPM.  My handheld tach couldn't read the reflective tape so it could be  it was just too dark last night.   I will get better data today hopefully.

 

I will also read the tach manual again to make sure the settings are right.  Glad you mentioned that.

Remember your LSE fires each coil twice as often as your mag. It is actually firing each plug on the exhaust stroke in addition to the compression stroke.  I’m sure you knew that but it’s easy to overlook when programming your tach.  Good luck.

Hi Richard,

 

Did not know you also had a Viggen project. That is unique! I am using Dynon servos and autopilot. So far, so good.

We have been on lockdown for 2 weeks so not done anything on the TriQ, but have been continuing to build the twin fins for the Viggen, that has been hard work as the plans are various scales so you have to play with sizing all the time to get it right. Will swap you some pics when they are done.

Hi All,

 

Had not been up in my Q for a couple weeks, so I thought I would take advantage of a nice calm, cool, crystal-clear fall day to do a short local flight. I have recently finished the final paint on my wheel fairings, so it is nice to have the airframe “finished”. Although it is a homebuilt, so I guess you are never really finished, right Sammy?

 

It was my first flight in a long time where the density altitude was less than the field altitude. DA was 4250 and field elevation is 4750 MSL.  So I guess you could call it a “low altitude” shake out flight for me. The good thing about cooler temperatures (5 degrees C at 1000’ AGL) is that it allows me to close up my radiator air exit doors and reduce drag. That adds some nice speed, so once I got up and level, I was showing over 170 mph TAS at about 70% power. Pulling it back to economy cruise (55% power), still gave me 160 mph TAS, which is really a nice speed at 5.5 gph!  The scenery is tremendous out here any time of year, but the lower sun angles make it really pop. Had to take a little opportunity to take it in, so I flew along the west edge of our valley (Grand Junction, CO) and flew down over the cemetery where my dad is resting and made a tight circle and couple of wing wags to say hello. The plane really likes about a 35 degree turn angle. It kind of “locks in” at that angle.

 

At my last condition inspection, I installed the autopilot servos, so I have been playing with the autopilot for a month or so. It is really nice to have, and having it hold altitude and heading is a real pleasure.  That gives you a chance to play with the engine settings without holding the stick. And magically, you can just twist the heading bug to make a turn. I have not used it for a multileg trip yet, but if I get the opportunity in one of the colder months, it will be nice.

 

Since it is starting to get chilly here, it is worth mentioning that I take my cabin heat air off the back side of the left and right radiators, so when I close up the exit air doors,  I get extra pressure on the hot air source into the cabin. That is a nice feature of winter flying for me, since that is the time that you are flying with the radiator exits mostly closed up.

 

My engine is really running smoothly and the rest of the plane is functioning as designed, so I am a happy homebuilder and now have 121 hours on the plane. Hoping to get out and see some of you in 2021, and maybe make that long dreamt of trip to OSH this year.

 

For those of you in Canada, hope you had a nice Thanksgiving, for those of you in the US, Happy Thanksgiving,  11 days from now, and for everyone else, I hope you have a nice November 26th!

Re: Success with LSE Install

Not sure just yet.  We just wanted to make sure it would fire up and only tested the MP drop as well as for EMI (have some, unfortunately).  The idle is definitely high so in need of adjustment.   We were chilly and tired from being out there late last night.

Today, I am going back out there to let it run and charge up the battery some more.  I would like to adjust the throttle body for idle as well.  If so, then I would also like to tie down the tail and do a full RPM static test.

Sure runs SMOOTH. RPMs were high so I’m hoping that’s just an adjustment on the throttle body.

After simply filing the holes to move the sensor out and up I filled the gap in the enlongated holes with hard gasket maker, then torqued it solid with slightly oversized washers and locking nuts. It needs to be held in place as it’s tightened of corse. I found the sensor to be much more sensitive to radial (up and down) positioning than gap distance to the disk. That dimension has quite a bit of slop with the crank fore/aft movement anyway. It has operated well with no issues for about 60 hours now.  I was surprised at how much of the case needed removed to make that bracket sit flat and flush with the case split line. I fly the hell out of my EZ and will do the same with my Q. Hope that helps.

In the first one, you can see how the new revised location of the sensor does not match the horizontal lines (going against the install manual).  In fact, they are way off (see earlier pic above).  This location gets a consistent spark every rotation.  If the manual is followed and the lines match up, but no spark of course.  In the second pic, I have rotated the magnet plate so you can see where the little "dot" magnet passes by the sensor.  It needs to pass by in this area or a tad lower.  The original bracket and holes had it passing at the very top of the sensor which is really far off from being read.

Again, it could be the sensor could come up a little higher so still adjusting before getting new brackets or welding of current holes done.

For those of you in Canada, hope you had a nice Thanksgiving, for those of you in the US, Happy Thanksgiving,  11 days from now, and for everyone else, I hope you have a nice November 26th!

 

Cheers,

Jay Scheevel, Tri-Q2 N8WQ, 121 hours.

After simply filing the holes to move the sensor out and up I filled the gap in the enlongated holes with hard gasket maker, then torqued it solid with slightly oversized washers and locking nuts. It needs to be held in place as it’s tightened of corse. I found the sensor to be much more sensitive to radial (up and down) positioning than gap distance to the disk. That dimension has quite a bit of slop with the crank fore/aft movement anyway. It has operated well with no issues for about 60 hours now.  I was surprised at how much of the case needed removed to make that bracket sit flat and flush with the case split line. I fly the hell out of my EZ and will do the same with my Q. Hope that helps.

In the first one, you can see how the new revised location of the sensor does not match the horizontal lines (going against the install manual).  In fact, they are way off (see earlier pic above).  This location gets a consistent spark every rotation.  If the manual is followed and the lines match up, but no spark of course.  In the second pic, I have rotated the magnet plate so you can see where the little "dot" magnet passes by the sensor.  It needs to pass by in this area or a tad lower.  The original bracket and holes had it passing at the very top of the sensor which is really far off from being read.

Again, it could be the sensor could come up a little higher so still adjusting before getting new brackets or welding of current holes done.

I've been a member of this group for a long time and never really post until now.. But, I use these Hall-effect sensors in my professional life and there is no way to know about the "alignment tolerance" with the document. These sensors are measured using the strength of the magnetic field. The Hall-effect sensor vendor will provide you with details about the spacing and how it effects the
magnetic field.

Here is a chart from a vendor that shows how the sensor operates in the presence of a mag field. Notice if the magnetic flux is not strong enough, the sensor will never turn on.

So if the vendor hasn't properly characterized the sensor, then it really could be a problem.

This is all very good information/findings for public distribution.

Seems like the free magnet passing over the sensor should be a recommended early trouble shooting procedure.  Maybe even a bench procedure for proving system function before an aircraft is involved.

"The alignment is within the tolerance of the manual but not enough to get the spark."
This is a problem. If the sensor is within the stated alignment tolerance radially and axially, but the system does not function, then the tolerance spec is wrong. Not good. 
Due to many factors, the stated alignment tolerance needs to be well within the actual alignment tolerance for system functionality. 
Otherwise someone could be on the cusp of functionality without knowing it and vibration, thermal expansion, sensor performance thermal effects, magnetic strength thermal effects,... could push it into the non-functioning region.
Added to this list are magnetic field shape and strength variation from the manufacturer.  This, of course, should be baked into the system level alignment tolerance.
What are the radial and axial alignment tolerance specs?  ,_

Good point.  I should clarify, it is set at .032” with the crankshaft in all the way.  I need to measure the gap with it out all the way.

There will be a certain amount of play in the crankshaft, so be sure to load the prop forward when you establish your clearance.

Good eye, Sam.  I just quickly mounted it there for the photo.  We are still drilling the adjustment holes to get it spaced up just right.  Aiming for .03” of clearance top and bottom.
