Hi Apophenia :)
Excellent work! Allow me some additions. A second PIK-21 was OH-XMR (see photo). Does anyone know what engine was used?
The PIK-27 was completed/flown. See photo.

Excellent, thanks Walter :) I've made the corrections and added a few details, links, etc.

Online refs to OH-XMR (c/n 4/453) list Arto Mäntylä Teuva as owner and builder (2001) but no engine details given. Perhaps, as with OH-XTM, a VW 1600 ... but with a more pointed spinner?

The original 1985 student paper shows that PIK-21 variants with 80 hp, 100 hp, 115 hp, and 125 hp engines were compared. http://www.elisanet.fi/ohxxv/pdf/PIK25.pdf

I notice that Airliners.net identifies both OH-XMR and OH-XTM as 'Issoire PIK-21 Super-Sytky'. No mention of that on the Issoire Aviation website (in fact, searching "PIK" brings 0 results) ???

I was designer in Eiriavion at that time, so source of information is my memory.
Some corrections and additions.

Pik-20. 1973 Prototype and first series (3+24), two part canopy.
Pik-20A was not an official designator. Used later to distinguish Pik-20 from Pik-20B
Pik-20B 1975 ailerons interconned to flaps. Single piece canopy.
Pik-20C was not used. Was reserved for what become JT-6, which was proof of concept prototype for PIK20E
Pik-20D. 1976 Flaperons, Schempp-Hirth airbrakes. Same kind of nose as 20B, horizontal tail in same location
Pik-20D-78, pointed nose and hor. tail moved forward

Finnish names for types.
Some are so specific finnish slang, that translation might be misleading. At best!

Pik-3a ok
Pik-3c ok
Pik-7 ok
Pik-10 Paukkulauta; banging board. Plank that makes banging sound.
Pik-11 ok
Pik-12 Kakstoistapaikkainen; aircraft with 12 seats.
Pik-15 ok Hinu is short version of "Hinauslentokone" / tow aircraft.
Pik-16 ok
Pik-17a Tumppi; shorty
Pik-17b Tintti; thermal, updraft
Pik-18 Sytky; in finnish fonetically how that VW engine sounds like.
Pik-19 Muhinu; Muovi Hinu -> shortened to MuHinu, (muovi=plastic), so plastic towplane, see Pik15
Pik-21 Super-Sytky; see Pik-18. Note that that "Issoire" is not correct. Issoire has nothing to do with this aircraft
Pik-23 Suhinu; Super Hinu -> shortened to SuHinu, see Pik15
Pik-24 Pileus; certain kind of cloud.
Pik-25 ok
Pik-26 see Pik-18
Pik-27; Sehinu; the last part "hinu", see Pik-15.
The first part (Se) is slogan sticking to a/c during construction. People were asking; What "Hinu" this is?
And after explanation, they understood and replied by sentence "Ai, se hinu". Meaning "Oh, so that Hinu!"
"se" is finnish word for "that" or "it".

Actually that Pik30 should not be in this list.
If this listing is for ”Polyteknikkojen ilmailuker....” then this Issoire factory given designator is not correct.
Pik ry has assigned designators for up to pik28 only. If someone gives a look-alike designator, the correct place would be a separate ”Issoire designators” list.

Any idea how PIK-A could fit into the list?

Here is a quote from Antony Kay's Turbojet History and Development 1930 - 1960 Vol. 1 (p124):

The Helsinki University of Techmology also used the Adder to power its PIK-A experimental jet aircraft.
EDIT: It seems the author has confused PIK-A (Finland) with Pika (Australia) ... :cool: . Pika was really fitted with the Adder jet engine.
