TYC is proud to offer affordable, 11 x 17 color sets of the late 1970’s M14-P/B training posters produced for DOSAAF either unbound, (so you can laminate), or spiral bound.
The bound version, with clear acetate front & rear covers, a title page & Table of contents, any of these 21 posters can be selected for study with the rest of the book folded back, making them essential either for the maintenance hangar or as a legit Coffee Table book you might give someone for the holidays.
This was not fifteen minutes at the color copier.
Original posters were flatbed scanned at high resolution and are presented here digitally printed at 300 dpi on substantial 12pt Matte coated stock.
The original Russian posters have some flaws. When item 25 of the Power Section diagram was described in the key as an “Intake Valve” but the arrow led to something more resembling a copper seal, we sleuthed the mixup and corrected them all.
The translations are of an extremely high quality and there were very few head scratchers, apart from maybe item 4 on the Air Starting system poster, where it took a minute to accept that the “Filling gun” was probably the fuel Primer.
Some deserve to be left alone, so that there will always be a little magic in the world, such as item 13 on the generator poster: ‘Electric Cardboard’
Original text was too small and illegible when shrunk from 36” x 24” down to 11” x 17”, so every specification table and number key to the parts has been recreated at a larger more readable font, and now hides the dual language original beneath.
Some things we could not fix. The beautiful Magneto poster depicts the advance retard type (M9-25/35) instead of the fixed timing M9F used on Yak 52’s. The carburetor poster lists 7 more parts than are enumerated on the drawing and while the lubrication poster is a masterpiece of colorful hot and cold oil flow paths through the sectioned motor, try to find “number 20. Oil pocket” on the original - you can’t do it, because although 25 items are listed in the key, not one arrow is there to tie described parts to the drawing. This, plus a truncated black detail arrow on the left edge, suggests the Lubrication poster originally had more real estate and was chopped at some stage. We have overlaid a key to the 11 items from the diagram that relate.
Individual versions of these posters, digitally printed on archival stock at 36 x 24, are available, however it would be best to gather a decent quantity from several interested customers to make this attractive for the printer... so please contact me by email @ firstname.lastname@example.org.
Several generous individuals have posted photos of these posters on social media, and, as I discovered when zoomed in, their text was Roumanian (?) only, and also a bit too blurry to read, - but at least you have a choice.
Not just the cost of the scans but the pre-press work described above is why we will not be offering electronic copies.
This business is how I feed our cats.
If you have ever had a Magneto coil go bad in the air, you’ll know it’s a dramatic & disturbing way to have a flight cut short. Old and overheating coils fail when adjacent layers of the internal wax/foil capacitor, deep in the winding, experience a short.
The run-up was fine but now, 20 minutes later, you’re at altitude, you’ve just completed some high power maneuvers when suddenly the engine dies completely or vibrates very badly. Reduced power may make the vibration disappear, but back on the ground and cooled down, the motor gives no evidence of any malfunction.
There’s no denying unreliable, aging coils are a potential safety issue.
The Yak Collection is proud to announce exclusive distributorship in US & Canada for Richard Goode Aerobatics’ new magneto coils.
In re-engineering this critical component, RGA obtained full EASA Certification through rigorous testing, also demonstrating 15-20% greater coil power output. Considering EASA is Europe's equivalent to the FAA, being able to certify a replacement component for a Russian magneto in 2020 is a real achievement.
Your unique coil is serialized and comes with its certificate of compliance in the package.
Different diameter mounting screws
These new coils have slots to suit one of two mounting screw sizes - so before ordering, determine whether your magneto has M5 or M3.5 screws holding the coil down into the magneto body. This will decide whether you need a coil with wide or narrow slots (see picture above) then use the drop down menu to choose the correct coil for your Magneto.
It was once true that fixed timing M9-F magnetos were all threaded for M5 coil mounting screws; while automatic advance / retard M9-25 and -35 magnetos, (and Chinese magnetos on Houssai engines), all had M3.5 screws. However, Magneto bodies with either thread size can be rebuilt up to either type of Magneto at overhaul, and this is exactly what has happened over the years.
Please don’t guess your coil’s slot width because electrical ignition components, while warrantied for performance, cannot be returned.
With the exception of the mounting slot width, the performance of all RGA Magneto coils is identical.
slot width identification
To easily identify your coil’s slot width you will need a flat bladed screwdriver that has a square or hex shaft, plus a wrench that fits.
Temporarily remove the P lead, above ( and make a mental note about how this affects anyone touching the prop) then remove the two rearward facing, long countersunk slotted head screws that secure the magneto coil cover.
The tight accessibility for the screwdriver’s handle near the engine Bearers, proximity to the oil cyclone for the left Mag, plus the generous contact area on those countersinks mean that mere mortals will find it hard to undo these two cover screws without the aid of a wrench on the screwdriver shaft.
Now, with the cover removed, finally you can compare the coil slot width against the images above and order the correct part with confidence.
removal and installation
Let’s proceed to removal and installation, once your new coil has arrived.
With the coil cover (mentioned above) removed, there is easy flat blade access to the two tab washers and hex head screws securing the coil.
To disconnect the coil electrically, you’ll also have to remove the larger horizontal cover over the rotor & distributor, which is safety wired. These covers have three hex head screws horizontally and four on the vertical front facing area where the ignition leads exit...a 9mm wrench takes care of all of them (and their heads are slotted also).
Take this opportunity to check that the pencil can be rotated freely. Lift up the distributor and rest it out of the way as you withdraw the pencil upward - just for the duration of swapping out old & new coils.
The Coil’s wire lug passes up through a hole in the magneto’s internal horizontal wall, where it attaches to the points; so release that screw....
...and if you have already removed the 2 screws holding down the coil, the old coil may be removed downward.
Installation is the reverse of removal and don’t forget to install the Pencil after the new Coil’s lead has been reattached to the points.
The lug from the capacitor on the new coil should be pushed onto the Hex head screw first, followed by the locking tab washer.
No need to get medieval with these slotted-head hold down screws, normal hand tightening with a screwdriver will suffice, in view of the security provided by the locked tab washer.
View RGA's full installation document here.
(Appropriate mounting screws and tab washers for your coil are supplied in the package.)
Replace and safety wire both covers as necessary.

November 2nd 2020 and if winter has returned to much of the USA, here in Ramona, California - today, we've got 78 degrees under a cloudless sky.
It’s an 18 mile trek North from San Diego, and a 1500 foot climb up winding Highway 67 through the foothills; past new reservoirs and old peaks that would have given Westbound Settlers their first view of the Pacific.
Massive eucalyptus trees come together high above the middle of the road leading into this old Gold Rush town. Take a left on Montecito, out to the airport and you could imagine yourself on the set of a 1970’s Jack Nicholson Biker movie remake. Pass the last few houses, drive past livestock then a horseriding school as finally a Fire Tanker Base comes into view, an aviation boneyard, a quiet helicopter museum, then the Control Tower, all telling you you’ve arrived.
At the edge of town.
To the North, overlapping blue grey mountains disappear quietly into the sparkling haze, somewhere in the general direction of the San Bernardino County Line, fifty miles away.
This is where Vladimir Yestremski has his maintenance hangar.
Around noon, somebody doing an engine test cuts the mags, a Vedeneyev clanks down to silence, the riveting stops and workers gather around a table in the hangar.
Lunches are unpacked, scents of Slavic grains, fish sauces and fresh bread replace the normal aromas of the hangar. Colleagues munch and watch in silence as enormous Red Tailed Hawks out in the meadow get their lunch too.
As the drone of the bees emerges from the silence, this much tranquility can get a little heady.
It’s probably no surprise, given the foregoing, that Vladimir has been making his own honey for many years.
Around this lunch table, I’ve heard the bees’ story many times and there are always more questions to ask. Did you know, for example, that the females, the ones you see flying around, are the ones doing all the work? Searching, cleaning, protecting the hive.
(The males all lie around in the Ready Room, telling yarns and getting fat on Nectar until it’s time to go inseminating.)
After lunch, while airplane work inside the hangar reverts to Yak conditional inspections, to Wing fuel bladder refits and elevator bellcrank installations, beyond all that, Vlad has his girls out, working the corner.
Worldwide there are 4000 different types of Bee, so it's pretty incredible that 1600 of them live in California alone; and while you will have heard how those Bee populations are under attack, local apiarists / pollinators are making a huge difference to Bees' comeback and health.
Now you, too, can enjoy Vlad’s Yak Attack honey.
Go to the high-priced “locally sourced” grocery stores and you’ll definitely see local honey for sale. But because you’re the detailed type, you also noticed the word ‘Blended’ on the label.
No Blends here.
Vladimir’s girls do their collective honey thing in ten locations throughout the Ramona Oblast. The different flavors are determined by which blossoms are in season.
Wildflower honey with Comb added for the offbeat Connoisseur looking for a little crunch...
Mustard Flower honey with a unique back flavor to compliment the sweetness, that you won't forget.
Eucalyptus honey. Pungent and reminiscent of the forest, with undertones of menthol and caramel. Love it or hate it, this is the flavor of choice for those starting to experiment with Mead.
Wildflower honey. Everything the girls could find in the neighborhood. All the aromas of Orange blossom, Acacia with their light sweet characteristic taste.
2020....What a year.
If ever there was a time to stop and smell the roses, the first week of November has to be it.
Each 2 1/2lb Gross wt glass jars contain 2lb Net Weight of honey. They are shipped in drop-tested packaging and are only available to customers inside the US.
OK, maybe we could drop one off at a Crew Hotel in LA.
But you didn't hear it from me.
