Hi! https://www.avialogs.com/ has AN 01-5E-2 Erection and Maintenance Instructions for B-24D,G, H and J No horizontal tail incidence given that I see, but it's airfoil is symmetrical NACA 0015. So if the angle of attack is positive, so is the tail lift (up). Wing incidence 3 degrees and from NACA war time report L-677 Fig 4 airfoil (2d) zero lift angle of attack is -2 degrees or so ( https://ntrs.nasa.gov/api/citations/19930092770/downloads/19930092770.pdf ) Maybe Liberator just flew tail high? But why? Cheers, Kari

Hi! Connected to the Liberator longitudinal stability. What was the horizontal tail angle of incidence (numerical value)? And did it change during Liberator evolution? Looking images from side it looks if Liberator had lifting tail instead of the usual downard force. HT seems to have large positive incidence - rudder hingeline is tilted backwarfs. I assume rudder hingeline was perpendicular to HT chordline. I may have it all wrong. Do type specifications for the various Linerator versions exist? Cheers, Kari

Hi! I remembered and found an old Britmodeller thread Underbelly camera ports on PR Spitfires. Flush or not? https://www.britmodeller.com/forums/index.php?/topic/72024-underbelly-camera-ports-on-pr-spitfires-flush-or-not/#comment-789194 There was a mud flap covering system for the vertical cameras. Late Edgar posted Supermarine technical drawing for the mud flap system. Sadly the image has gone as is Edgar. Has anyone saved the drawing image? Cheers, Kari

Tere! Very nice model! I remember seeing a set of excellent photos of this aircraft at Fotis (Estnonian film and photo archive) and then wondered if the nacelles were red or blue. You seem to come up with red, that is good looking. Cheers, Kari

We need to talk about Dark Admiralty Grey
Kari Lumppio replied to Phantome's topic in Aircraft Modern
Hi! Somewhat idle recent (at the time of writing this) postings in this thread: https://www.britmodeller.com/forums/index.php?/topic/235123204-all-your-il-2-questions/ I guess A-14 may have varied somewhat. cheers, Kari -
We need to talk about Dark Admiralty Grey
Kari Lumppio replied to Phantome's topic in Aircraft Modern
Hi! Whatever it is worth, Humbrol 5 Dark Admirality Grey was closest Humbrol/Revell match to the Soviet A-14 sample (Albom Nakrasok), only gloss. On WW2 section at the moment there is some discussion going on about it. Cheers, Kari -
Use of wooden planks in Luftwaffe revetments..
Kari Lumppio replied to Phas3e's topic in Aircraft WWII
Hi! I should have been more specific. The Jõhvi photos appear in some two- three books at least. I am not lookig books or other publications. The photo series(es) are official PK photos and are in German archives. In ECPA too? It is the photo archival codes I am looking for. Thanks anyway for reaction. Cheers, Kari -

Kari Lumppio replied to Phas3e's topic in Aircraft WWII
Hi! These photos do show NSGr 11 Heinkel 50s at Jõhvi, Estonia early 1944. Only the taxiways were planked wood as much as I remember from veterans' books and stories. If anyone knows archival code(s) for this/these photo series(es) I very much would like to know. Been latently searching for them from like 1996 or so. Cheers, Kari -
46 kits identification problem - 4 left!
Kari Lumppio replied to Rob de Bie's topic in Aircraft WWII
Hi! Model number 14. An Il-2 "07" from 566 ShAP. On one side of fuselage is "Za hristenko" for fallen comrade. Hristenko was KIA April 1945! There was no Leningrad Front any more then. 566 ShAP was somewhere in the Baltics with 1 VA IIRC. 566 ShAP had two white rings around rear fuselage during 1944 (June, post Vyborg operation). I think one can see overpainting of those on the original subject photos. For what it matters. Cheers, Kari -
Hello! There is that old saying: If you think safety is expensive, try accident... Cheers, Kari

question about Finnish Bf 109G-6 camouflage
Kari Lumppio replied to ruudster's topic in Aircraft WWII
Hei! Like I already wrote there is more to it. One detail. Wooden high vertical tails were lightened in colour (overpainted. squiggles. In RLM 76?) already in Germany. Study carefully period photos! When in Finland the second overpainting on vertical tail did not stand out as much as for example on wings. My thinking is that wing paint surface was smoothed and overpainting shows because of the surface texture (spray roughness difference), not because colour. Same for fuselage. Cheers, Kari -
question about Finnish Bf 109G-6 camouflage
Kari Lumppio replied to ruudster's topic in Aircraft WWII
Hi! I and as far as I know no- one else has found archived documents which would list the paints used for the overpainting of German markings and stencilling of Bf 109s. Like you said the overpainting does not show, so logical assumption is the German Luftwaffe paints were used. But no documentation for that. Summer 1944 the State Aviation Factory (Valtion Lentokonetehdas - VL) sent detachment to field (Lappeenranta) which took care of all of the incoming Bf 109 inspection, including change of markings plus stencilling and placarding in Finnish. Professionals with lots of repetition af the same task performed the overpaintings. I think that is a factor of the apparent neatness. There is more to this for different periods of Bf 109 career in Finland. Late Summer 1944 paint material conservation was ordered. IIRC among other things German paint thinner/ activator stock was shrinking with no resupply in sight. Unnecessary painting was to be avoided. That is why for example MT-431 received only the black part of the Finnish war paint ( green & black top). Cheers, Kari PS MT-437 (yellow "9" and lynx head on fin) and MT-439 were the first HLeLv 24 Bf 109 G-6 to be painted in Finnish markings. On the very same day. -
