seiran01 Posted September 8, 2014 Author Share Posted September 8, 2014 Great info, thanks Chris! I'm forging ahead with the jumos out of the box and will post pics of the external bits a bit later on. I don't think the rear attachment point is on the model but then again it seems these jumos are attached at the sides or bottom, not the top, as the only metal over most of the engine is only the nacelle cover. daHeld 1 Link to comment Share on other sites More sharing options...
seiran01 Posted September 9, 2014 Author Share Posted September 9, 2014 Chris, engine pix for you! They have added the rear attachment point, i can't tell about the generator (molded on gearbox) and rev controller shapes so interpret the pics as needed. I've asked Jeff Cadenhead if I can repost pictures of the Jumo he's built from his kit - until he replies, check them out on his facebook page "What Ever Happens To Be On The Work Bench," it's the 3rd post down daHeld and Chris Wimmer 2 Link to comment Share on other sites More sharing options...
seiran01 Posted September 9, 2014 Author Share Posted September 9, 2014 And with permission, I'm excited to share what can be achieved with the ZM Jumo 004 engine out of the box. Here are some shots of Jeff Cadenhead's beautiful engine from his Horten kit. Note that the black heat shields are added. The black lines on my engine above correspond to where the shield sits. Note also the engine stand here - the parts for the stands are cleverly molded as part of the sprues holding the engine pieces!

Wouter Posted September 9, 2014 Share Posted September 9, 2014 Hi Seiran, If your still planning to use a BMW003, I have 'found' some reference for you. HPH models have a 1/18 scale model of this engine and the construction manual goes into depth of building one, including all the plumbing and pipework. You can find the manual here: http://www.hphmodels.cz/images/stavebni_navody/bmv_003.pdf cheers, Wouter daHeld 1 Link to comment Share on other sites More sharing options...
Chris Wimmer Posted September 9, 2014 Share Posted September 9, 2014 Thanks for the pics, Mike! I did some research work in between and these are my results: The revolution controller, fitted to the only remaining Jumo 004 prototype engine, which is on display at Hannover/Laatzen museum. The ZM kit part is looking quite accurate! Jumo 004 on the Me262 at Deutsches Museum Munich: Note the generator protruding over the gearbox: I can hardly imagine that it found enough space in the Horten wing: Looking into the Jumo maintenance handbook I found that the generator isn't mentioned there at all! So I came to the conclusion that the generator isn't actually part of the Jumo itself, but rather an aircraft-specific device. To me it seems possible that it could have been replaced by a smaller one. Looking forward to seeing more of this build!

seiran01 Posted September 10, 2014 Author Share Posted September 10, 2014 Ok, oil on the wing and control surfaces finally dried, so I've sprayed a thin coat of clear orange over it to finish it up. Wing fuel tanks have been primed in tamiya semi gloss black, for a dull-ish alclad metal finish. Started priming the engines as well, no pics to share on those yet sorry guys With the exception of the drag rudder pushrod assembly, this is the complete inner wing pieced together pre-painting. The grey piece in top of photo is the compass which will be attached to the inside rear lower wing at the root. I'm loving this!!!

seiran01 Posted September 10, 2014 Author Share Posted September 10, 2014 Looks like I'm going to need to fine sand/polish the frosted outer surface of the upper wing in an attempt to make it crystal clear. As it stands right now, the wood effect looks like a blob of plain orange, and we can't have that! daHeld 1 Link to comment Share on other sites More sharing options...
Wouter Posted September 10, 2014 Share Posted September 10, 2014 Looking into the Jumo maintenance handbook I found that the generator isn't mentioned there at all! So I came to the conclusion that the generator isn't actually part of the Jumo itself, but rather an aircraft-specific device. To me it seems possible that it could have been replaced by a smaller one. As I recall, the Horten brothers run into that problem after switching from the BMW003 to the Jumo 004. The generator wasn't mentioned in the drawings they got from Junkers but when the first engines arrived they where surprised to find the generator on it. It wouldn't have fit in the airframe. To adept this problem they were allowed to fit the generator somewhere else in the airframe. I'll check my reference on this when I get home.
