Bavarian RC – Heinkel 219 night fighter design and build

After completing my first own foam board design, the Nord-2501 Noratlas (Link) it was time for something a little bit bigger and more like a WWII fighter. As I really like twin engine planes, the list was quickly narrowing down to the Heinkel 219 night fighter.

The first step was as usual to find a 3 view drawing:

The scale will be approx. 1:16 which will give me around 1160 mm wingspan and an overall length of 980mm. I want to power it with 2 B-Pack motors. If my rough calculation is right, I should end up with an AUW of around 900 - 1000g… let’s see.
My Noratlas was quite square, so this time I want to use more molding techniques, especially on the huge nacelles.
I spent the last days with drawing the main parts in CAD and it is time now to start the build of the first prototype.
The first step was the fuselage:

And the nose cover:

Doublers for the wing support:

I'll post more updates along the design and build process...

Thanks! You‘re right, the nose cover is inspired by the Bronco. If possible I will fly it also with on-board video. Depends a bit on the CG, I fear this thing could be a bit nose heavy with the position of the motors. In that case putting a GoPro in the nose will not work. Let‘s see...

The horizontal stabilizer has dihedral, which so far has caused some headache for me. I am still wondering how to connect the split elevators in a simple way. As I haven’t come up with a good idea yet, I think I will use two separate servos and mix them together. I will see when I get to that stage. Anyway the test fit looks OK :)

Next step is the wing. After "endless" cutting of scorelines I made the bevel cut at the leading edge, glued the wing halves together in the middle and reinforced the wing tips with BBQ skewers (this helps a lot to prevent damage from “not so perfect” landings). Not that I would need that… LOL ;)

The outer part of the wing has dihedral, so the attaching of the spar has to be done quite thoroughly to ensure a correct geometry of the wing. I first glued the inner section, then put a gauge with the correct angle under the outer wing and glued the spar in this section. To reinforce the spars I used popsicle sticks on both, the front and rear spar (in the middle of the wing and where the dihedral starts).

So far the build is quite straight forward and things go together nicely.

Today I completed the wing. It is a classic fold-over wing. The only tricky thing was the dihedral of the outer part and the overall geometry with 3 trapezoid sections. I wasn’t too sure, that all the folds would fit together as the wing looked a bit strange on CAD. Due to the straight leading edge (without sweep) there were no wedge-shaped cut-outs needed on the upper side. Finally it all matched up. :cool:

It’s already starting to look like the original Heinkel 219:

It is quite a big bird, bigger than I expected it to be, but it still fits in the trunk of my car without disassembling, so everything OK ;)(y)

Thanks Grifflyer, not sure if I will paint this one, as it is the first prototype. My plan is to build this prototype, hopefully get it to flying and collect some experience with it. There will for sure be a lot of improvements I could make. At the end I want to build a version 2 of it with all of the improvement. This on I will paint for sure. I also want to do a build video, but not sure if I will find the time for that... it is quite a lot of effort to do.
For the paint scheme I think I will do this one:

Really nice!!! I love the twin tails.

I hear you in the build videos, I tried on once, building the plane was a pretty stressful experience always worrying about if the parts are in frame or not. The footage I got was all overexposed, so you couldn't really see what I was doing. To top it off the audio was horrible:ROFLMAO:
I have mad respect to anyone who does a build video now.

That's a cool paint scheme!

Thanks. Yeah, the twin tails and the dihedral horizontal stabilizer were one of the reasons for chosing this plane. In the mean time I read a little bit about this plane and it seems that it was quite ahead of its time. In fact it was the first serial built fighter equipped with an ejection seat. But I think I won't include that feature in my build :LOL:

Yes, you are so right. Normally building is pure fun, but when you are recording it, it is far from being relaxed. Not to mention the effort for editing the video, I've seen this when doing the build video of my Noratlas.

Great model! I bought myself a 1:32 plastic model kit before starting the design of the He-219. The idea was to build the small one first so that I wouldn't have to base the design only on a 3-view drawing. In the end I was so excited to start the design, that I haven't touched the model kit yet. I have other priorities now: Build it and (hopefully) fly it!

So here comes the most challenging part … at least for me: The nacelles.
I had to spend quite some time for calculating and designing all the pieces in order to match after molding and glueing.

The inner frame:

IMG_0367.JPG IMG_0368.JPG

Molding and glueing the first (cylindrical) part. I thought it was a good idea to leave the paper overlapping to get a better transition to the ring that will be installed in the front, but I finally decided to remove it.

IMG_0369.JPG IMG_0371.JPG

Step by step adding formers and cones:

IMG_0372.JPG IMG_0376.JPG IMG_0379.JPG IMG_0414.JPG

Puh, 26 grams and looking quite OK… not bad for the first try. The only mistake I made was to build it without the power pod inserted. This caused the whole nacelle to be a bit twisted.
Test fit on the wing:

IMG_0475.JPG IMG_0474.JPG

Despite the fact that I burned my fingers several times with the hot glue :eek: while trying to wrap the cones around the frame I am quite happy. Tomorrow I will do the second nacelle. Now that I know how it works it will be for sure easier.

That looks really good! Did you design the parts in 3D?
