Fly Out Bag Lunch Affair

June 10, 2020  I put out emails to see if I could get anyone to join me for a flight.  I figured I would treat myself to a flight to Hanna Alberta and have a bag lunch while sitting there in their nice airport terminal building.  This would be about a one hour flight for me in the Quickie.  One other friend said he would meet me there as well.  To my surprise on arrival there were many who got the email and were also excited to get out flying.  There ended up being 10 airplanes attending with people from High River, Medicine Hat, Airdrie, Kirkby Field, Three Hills, Springbank as well as farm strips.  We all had a great get together and chatted about all things aviation and engines.  I will be organizing more trips like this as it gives us an opportunity to fly to many airports where food is not easily accessible yet they have a nice terminal building.  Sorry I forgot to take pictures of the planes and people this time.  Thanks to all that came out flying.

First Flight on New SDS CPI Dual Electronic Ignition

May 9 2010
At 10:30 this morning I got my bird in the air once again, only this time running the new Electronic Ignition from SDS Ignition Management.  After a pre-approved clearance to get above the airport for racetrack pattern testing I climbed out toward my planned 7000-7500 foot pattern staying east of the airport.  I ran the engine full power for the complete 1 hour session and everything ran perfect.  Airport elevation is 3960 ft and the temperature at 7000 ft was 2.2 degrees C.  I ended up spending most of my testing at 7000 feet.  I am realizing 100 more RPM from my engine at full power static on the ground tests.  As a result I am now getting higher RPM in cruise and thus higher airspeed.   It is a bit early to tell but I am seeing almost 10 more mph indicated at this altitude and temperature.  My previous max RPM's  would be around 2950 and now I am seeing 3000 - 3180 rpm.

Electronic Ignition Switches and Battery

May 7, 2020
Last few days have been spent installing the wiring, the Emergency backup switch and the Emergency Backup Battery.  This morning I picked up a small 12 volt 5 AH battery for use as backup power.  Work was completed and the plane placed outside and started again for a test of the Emergency Backup Power source.  Switching onto the Emergency Battery and turning off the Main Alternator and Master switch kept the aircraft running fine.  The backup battery supplies power to the Electronic CPI programmer and Coils alone.  Numerous switching onto the backup at various RPM's was a success.  I made a battery box for the new Aux. battery out of foam/fiberglass.  It is mounted right behind the seat back in the luggage compartment and is secured to the floor.  There is a Emergency Ignition switch mounted on the far left if the panel.  Magnetos have been totally disconnected but not removed.  Each battery can be tested via a volt gauge prior to starting the engine and charge votage can be tested after the engine is running.  The plane is all buttoned up and prepared for first flight on the SDS Electronic Ignition.

Electronic Ignition Full Power Test

May 1,  Today I got the plane out and ran the engine up to warm it up.  Now I wanted to test the maximum continuous RPM  power.  The engine performed great as I went through about 5 rounds getting the RPM up to maximum.   I am seeing a increase of the static rpm of 100, now registering 3000 rpm when leaned.  Everything went great and I am very happy with the performance.

One of the major reasons for installing the CPI was to get rid of excessive static noise in my headset which had been proved coming from the magnetos.  A test of the radio is now crystal clear with absolutely no static background noise at all.  Yahooo.

May 2/20,   Yesterday I noticed the first engine start of the day did not start quite as well as day one.    I noticed a slight bit of kickback if the engine did not fire  on first cranking attempt.  After a call to SDS Ignitions I was informed of a "Start retard" option in the programming which retards the startup timing so the engine fires after TDC.  The original default setting sets startup firing at 5 degrees after TDC,   A call to SDS  informed I should change the starting spark for 10 degrees after TDC because I have a small wood prop with low inertia compared to a metal prop on a Lycoming.  This fixed my problem of kickback on startup.

Next is installing the Emergency battery a small 5 ah sealed cell and a dual voltmeter for testing each battery.

First Engine Start on Electronic Ignition

April 30/20  Today I finally had everything connected.  It was time for the first start using the new CPI Electronic Ignition from SDS Ignitions.  The Revmaster engine fired up after three full revolutions which is it's normal cranking for startup.  The engine ran very smoothly through a few low RPM settings and then I shut it down.  A friend assisted me in setting up the initial timing of 10 degrees using his timing light.  The timing process was completed in fifteen minutes.  After timing was completed I went through the programming and set all the vacuum settings as per the default table in the user manual supplement.  The original magneto spark plug wires are tie wrapped up out of the way and the magneto switches are grounded so the mag cannot produce any spark or noise.

Electronic Ignition connections nearing completion

April 26/20,  The plug wires are connected and the CPI control unit has been wired up.  Initial timing of the CPI was completed as outlined in the user manual using a timing light and once completed doesn't have to be done again.
Below you can see the prop bolts with the trigger and sync magnets installed into the ends of three of the bolts.  The magnets protrude 3/16 inch.  This is a top down view .  The wire is a extension of the center line of the engine case to enable using a timing light to set the initial timing angle.
 The photo below shows a refinement of the timing mark (10 deg BTC) on the crank.  I placed a piece of black vinyl tape on the crank and then a small white piece on top of the black.  This trick was  advice given from a friend at the airport who has installed the SDS system CPI units a few times.

 Below is the CPI programming unit temporarily hanging on elastics during my initial start up, testing and programming.  You need access to the programmer to monitor some settings and adjust a timing parameter.

Finishing up the Electronic Ignition (Continued from July 2017)

April 22, the cold weather has finally departed and it is back to the hangar to finish up the electronic ignition.  Major components had been fabricated and installed two years earlier, now to get it completed.
Below are the original plug ends and the new MSD plug wires included in the CPI (Coil Pack Ignition).  The original plug ends were about maximum size that could be installed on the bottom  plugs, the new ones were way to big to fit.  Fortunately the new wires have a small plug on the opposite end.  I was able to install the small end of the new plug wires onto the bottom plugs by trimming off a bit of the rubber nipple on the ends.  The small plug end can be seen in the photo of the coils where I am using 4 small and 4 large ended wires on the coils.  The photo below is a end view and a top view.

Below you can see the two sizes of plug wires that I have installed onto the coil packs.  The coil packs require a 10 amp fuse to each and the CPI programming controller requires a 3 amp fuse.
