- Wecome for this new edition! This time I feature the JENA story.AS there is not a lot info about this lovely Jena engine range to find on the web,I deside to bring a video on that subject.
The Jena concern is world wide known for there high precision products on optical instruments,lenses,range finders,microskopes and many other things as well in WWII bomb sights,periscoopes and other high precision miliitary hard ware.
After the war the go also as other precision companys in the production of model engines.
From 1951 till 1965 they make a range of lovely engines.Mr. Walter Hercher and Karl Zacharias were the brain childs for those engines.Later on,alsoMr Walter helmuth Kratch from the "Kratmo" engine fame join the team at the moment ,when they design the Glow 2,5 in 1965.
AS said in the clip,the early engines are the best with a very cosisten quality.Because of the comunist regime,later on they had issues to get some times the right steel and good ball bearings for there production.
Never less,I found them a very sound design,good power,and clever made,with attention to small details.
The engines come regulary for sale on ebay,so as sad,try to go for the early types,and you should be not disapointed,if you find a decent engine. - Авто та транспорт
Very nice collection you have there 🤙thanks for all info
Many thanks my friend!! Very kind of you! ;-)
The best technical documents are usually in German. I've learned a lot of German language thanks to reading manuals and technical stuff :-)
Loved the running engine!
Groetjes uit Middelburg und mach weiter so!
Thx Huib! Its a sweet racer..pretty rare..Great engines...
Magnificent video and engines! Awesome Peter!
Hi David.Thanks a lot. I love them as well so much!!.... ;-D
I came back to Your films lately Piotrek and I imagine a young boy in 60s running with free flight model Jena powered, trying to fire it up, launch and watching where it goes :-) Now this Jena is in Your hands, could not have been better... What a nostalgic times...
Nice to see it bring memories back Marcin!!.. I am sure, a lot boys in Poland in the 1960 did use them..and the Jaskolkas..and have so fantastic times...I have also some memories...LOL..remember once with a good friend we build a Bi plane...just out of balsa .We use a Cox engine...I think with a Peewee 030 engine.. the glue was not even dry..and we let it free fly....it took circles... up..and up..higher and higher.. in the middle of the town...and suddenly it go down..engine full roar..like a Stuka!!..it crashed of course.. but engine survive!! ;-).. we did crazy things!!!
Informative and educational as always. Thanks Peter.
Your welcome. This are very nice runners .I hope to fix one day the broken lug to tight down the head again.The plain bearing version of the Activist s rare as the Pionier it self..
Whoooow Peter, I am happy to get powerfull black big head aktivist Jena :-) Fantastic story ...
Hola amigo! Yes,you can be proud with it...Its gonna now a huge packet...I must check for a bigger box now!! ;-D
Good to see someone with a passion for these fine old engines. I have recently obtained a 'Black Head' JENA motor, a Glow Plug version, sadly it is missing it's carburettor. Any leads on obtaining a carburettor would be appreciated.
Ho John. Many thanks for the kind words...What exact parts do you need? A C/L carb or an R/C ? Kind regards from the Netherlands.
@@valic000 R/C would be good. I see that the Carburettor mounting on the crank case is threaded.
@@Huckebein2 Is the engine you have similar to this engine_ Or the later engine with two ports?
.
@@valic000 unsure 🤔 I have not striped it down yet. I could send a photo... Messenger or WhatsApp.
very nice!
Many thanks! Its a lovely engine range!
Great video Peter very nice collection you got it running great too Jose will be very happy Bill
bannisterengines Hi Bill,yes,its a lovely collection,but still not compleet,as they make so many types.The Pionier is really awsome,will try to run them one day.this is my pension money for later...i have some very rare dutch engines as well.Will also make a clip about them as well.Just packet all the stuff for José,so yours is next in the waiting room
;-D have a relaxed evening Bill!
Hello do you have a spare crankshaft for a DC sabre engine?thank you
Hi Cristian. I am sorry, I have no spare shaft left. But on Ebay, a donor engine would be not expensive so you can use that for spare parts. A run down Sabre in poor condition will be cheap...
Good luck, if I see one, I let you know!
I have one engine in my microcollection. Unfortunately, it has an incomplete fire extinguisher. Somehow the performance is impressive.
Hi,I dont understand,what you mean with fire extinguisher....
Sorry for the translation. I meant the carburetor.
T W .ok,thanks,that make more sence! But what do you need?
OK, meybe you can send me e-mail? egabarg@gmail.com
In response, I will send a photo and describe it. here is nothing like uploading photos.
Carl Zeiss:-)
Hi Marcin.Yes,you know them very well for sure!! I have a 2.5 blackhead..needs a bit work,,If you want have one! ;-)
