JWM Posted June 10, 2018 Share Posted June 10, 2018 (edited) Hi, Aero A 100 is a light recco-bomber produced between wars in Czechoslovakia. There is a injected kit of this machine in 1/72 by Kovozavody from some eighties I think. A 101 is its developed variant. A 101 kit is produced as resin kit by CMR. A 101 is very sttractive due to use of this machine in Spanish Civil War, on both sides of conflict. I will try to do scratch conversion of A 100 into A 101 with parallel build of regular A 100 in Slovak colours. Many people think that diffrence is only in engine, undercarridge and fuselage lenght. This is unfortunatelly not true. The main problem is that A 101 has much larger wings... Not only bigger wingspan, but also chord. So the conversion is a bit more challanging. Besides Spanish drawing by Molina & Mercado (Aviones em Guerra Civil...) I have nice drawings from Letectvi + Kosmonautika from 1988. And two kits by Kovozavody, which are with me for some 20 years... More in next post J-W Edited August 13, 2018 by JWM upgraded topic 4 Link to comment Share on other sites More sharing options...
JWM Posted June 10, 2018 Author Share Posted June 10, 2018 Drawings from L+K (photos, not scans ) A 101 and A 100 Model fits drawings of A 100 perfrctly Here one can see how longer is fuselage of A 101 and how bigger are wings So I cut wings and start to enlage both chord and wingspan To be cont Regards J-W 9 Link to comment Share on other sites More sharing options...

JWM Posted June 11, 2018 Author Share Posted June 11, 2018 Small corrections - the resin kit of A 101 is by Planet... A-100 by Kovozavody is produced since 1988. Here are some schemes for A 101 from SCW And here Slovak A100 from Polish campaign in 1939 Regards J-W 4 Link to comment Share on other sites More sharing options...

JWM Posted June 13, 2018 Author Share Posted June 13, 2018 Hi, Wings after first sanding New filler added on sme areas and wings wait for next sanding,. The engine was cut off and side windows were cut out. Please note, that in A 101 and A 100 those windows are on different places. I started to construct new engine. Despite all similarity the A 101 has much bigger W type engine To be cont. Cheers J-W 5 Link to comment Share on other sites More sharing options...
JWM Posted June 16, 2018 Author Share Posted June 16, 2018 (edited) Hi, The wings are now basicly enlarged, waiting for rescribing (or rather re-doing) surfaces. Comparison of upper wing (original white one of A100 and enlarged of A 101) and lower wing Next will be adding of ribs, scribing ailerons etc. Some work was dome with engine: More sanding/filling need before detailing will start. The prop in A-101 rotates other way then in A-100 so I have to find directly or to find snd copy in resin some big two blade prop of correct rotation. I am going to dig for it... to be cont Cheers J-W Edited June 16, 2018 by JWM re-upload of photos, they were not displaying.... 5 Link to comment Share on other sites More sharing options...
TheBaron Posted June 16, 2018 Share Posted June 16, 2018 More of your quality work Jerzy. Something quite singular and attractive about that aircraft about which I currently know nothing but hope to learn more watching you at work. Good luck with this engaging project!

JWM Posted June 17, 2018 Author Share Posted June 17, 2018 Tony, thank you. You may google about the Aeros 100 and 101 but not too much there besides basic infos. Anyway - nice and a bit odd family of biplanes.... The A-101 was mainly used in Spain. Wiki says that some 52 were sold to Republicans (out of ~60 build). However a ship with one set was captured by Italians on the sea and via Italy they went to Nationalists. Therefore were used on both sides This huge engine of A-101 is a licence build of an Isotta Frascini 18 cylider W type, 1000 HP (max).

JWM Posted June 17, 2018 Author Share Posted June 17, 2018 Hi, some work inside started for both: Since about 2 cm I will have to add to fuselage the angles have to be changed. I cut off the end of fuselage and glued it to have smaller height,,,, To be cont J-W 3 Link to comment Share on other sites More sharing options...

JWM Posted June 23, 2018 Author Share Posted June 23, 2018 Hi, Over week I have no time on this, so some break appeared. On 6/18/2018 at 5:54 PM, Herb said: A manly conversion! The smell of plastic dust and putty is thick in the air... Indeed, the conversion is a big serious than I thought. I started to think on those angles etc with longer fuselage and found that it is differently that I though, The tail section looks looks almost identical in both (it is a bit different in Ab-101, but this is out of interest here) Here two drawings in passing through light So I had to restore tail to original look but I have found that Auro 101 has more that 1 mm deeper fuselage in 1/72 in cockpit area. Here it can be also seen (together with differecies between angine and cockpot which is really serious So I had to cut fuselage horizontally Then I did some details insides and glued together. I started to do extension Much simplier for A 100 Good time to let it dry... to be cont Jerzy-Wojtek 4 Link to comment Share on other sites More sharing options...
JWM Posted June 24, 2018 Author Share Posted June 24, 2018 Hi A-100: I had to put some kind of distancer inside engine, just to prepare in to glue upper and front parts of engine. This is this white rod seen on front I opened inlet and outlet of cooler because I want to do more realistic look of cooler... A-101 fuselage after some sanding with new portion of filler added: Note that fuselage, in front of cockpit is much rised than in case of A-100. I Added there putty.

JWM Posted June 25, 2018 Author Share Posted June 25, 2018 Hi, Since putty on A 101 fuselage is not hard enough I am pausing with it. But I did today some work on cooler of A -100. I think that it should be the main improvment of A-100 compare to OOB build. The front view: As can be seen here I put a plate on top of cooler space Now it is open but I will do cooler itself and the grill. To be cont.

Artie Posted June 25, 2018 Share Posted June 25, 2018 (edited) you're a very brave man, J-W.........hats off.....!!!! Did you know they were called "Oca" (Goose) in Spain?????? Edited June 25, 2018 by Artie 1 Link to comment Share on other sites More sharing options...

I've heard name "Praga" for A-101. Perhaps one was given by Republican, second by Nationalists? "Praga" supports a bit orgin of nick name for I-16 (but not Rata, only Mosca) - which is supposed to be developed from Moscow...On sky it must look a bit as a goose - but flying backward! - since large wings were moved to front and then a long, long fuselage with small tail happend...:) Cheers J-W Link to comment Share on other sites More sharing options...
Artie Posted June 26, 2018 Share Posted June 26, 2018 Yes, the name Praga was used as well........I think the nickname "Oca" relates its origins to the fact that they were very easy to down....but who knows, spanish people have been always very imaginative when it comes to give a nickname...!!! 1 Link to comment Share on other sites More sharing options...
JWM Posted June 26, 2018 Author Share Posted June 26, 2018 Hi, Results of coarse sanding of fuselage of A -101: For comparison with A-100 and engine On abive photo you may see an old piller, broken some +60 years ago by my Mum ( ) when she tried to use it as levar. It makes great job in all my scrach builds as caorse piller since 40 years... Next portion of filler added to be cont. Cheers J-W Link to comment Share on other sites More sharing options...
JWM Posted June 27, 2018 Author Share Posted June 27, 2018 Some progress with A-100. I glued lower wings and tail In v-type engines usually I am doing longer bearing to have prop more stable and still rotable I made two pieces of fine stainless steel net to imitate radiator (cooler) And i glued top cover of engine That it for today evening all for Aeros To be cont Cheers J-W 4 Link to comment Share on other sites More sharing options...
Brandy Posted June 28, 2018 Share Posted June 28, 2018 I've just caught up with this one, Jerzy. A very ambitious project, but as usual you're doing a great job. Another one I'd never heard of too! Ian 1 Link to comment Share on other sites More sharing options...
JWM Posted June 28, 2018 Author Share Posted June 28, 2018 Thank you Ian, this Aero A-101 is perhaps a bit better known due to use in Spain during Civil War. But A-100 is really rather obscure type. There is also the latest produced in small number variant Ab-101, which has large airframe of A-101 and modern high power V engine instead of W engine in A-101. There was also further development - a single prototype with parasol wing (no biplane) Aero A-104, which really looks nice Pitty that was not produced...

ReccePhreak Posted June 28, 2018 Share Posted June 28, 2018 I had one of those A100 kits decades ago. A modelling penpal from the Czech Republic sent it to me, as he knew I built recce aircraft. I never started on it, as I could never find definitive proof of where the camera(s) was/were installed. I may still have the kit in my stash somewhere.

JWM Posted June 29, 2018 Author Share Posted June 29, 2018 (edited) Larry, at least in case of A-101 it looks that camera was situated just behind pilot. In post #2, on top drawings there are presented sections of fuselage. On third from top small sections (upper left corner of picture) you may see a vertical tube-like shape which looks like camera to me. In the bottom view there is a small square a bit assymetric in the middle of fuselage - it is perhaps an opening for camera. But I am not 100% sure about this interpretation. In case of A-100 there is nothing on the bottom of fuselage like that... So I do not know where is camera in A-100...

I am almost convience to do the italian style camo of Nationalists 17.12 - i.e. scheme "B" from my post #4 above. Cheers J-W Link to comment Share on other sites More sharing options...
