Herpa B737 MAX mould.
 

Ciao to all.
I remember when we started to share opinions about the B737NG new mould, a lot of posts, impressions, opinions, comments and then Herpa offered us a good mould.



What do you think of Herpa new B737-800 mould? / Comparison (https://www.wings900.com/vb/images/misc/multipage.gif 1 2 3 4 5 6 7 8 9 10 ... Last Page)


Now Herpa announced the B737 MAX, "8" and "9" version, a completely new mould according to latest infos.
Looking at Aviation Center Berlin website, there is the pic of a B737-800 with MAX winglets and LEAP engines

(recognizable for the "slots" in the rear part). This model could even be correct, the problem is the
lack of "pointy" tail cone.

The main, exterior differences among the B737-800WL or W (winglets or scimitar winglets) and the B737 MAX8 are: winglets, bigger and larger engines, stretched landing gear, "pointy" tail cone section.
The MAX winglets are different from the "classic" B737-700/800/900ER winglets and from the scimitars; the CFM LEAP-1B engine has a diameter of 176 cm, 19 cm larger than CFM56-7B used by the B737NG: this means that, to leave the usual 43 cm from the engine and the ground, the MAX landing gear has been stretched of 20 cm. Exteriorly the two engines differs because the LEAP has some slots on the rear part.
Even the tail cone section is different: pointy on the MAX.
Some measures:
B737-800: lenght 39.5 meters; wings span 35.7 meters; engines diameter 1.57 meters
B737 MAX8: lenght 39.5 meters; wings span 35.9 meters; engines diameter 1.76 meters.


For 1:500 scale models the lenght and the wings span is the same, but the mould must be different because of the pointy tail cone of the MAX.
The engines, apart from the small "slots" on the LEAP of the MAX (Herpa has realized good "slots" on the B787 engines), must be different:

( cm = centimeters mm = millimeters)

B737-800 -> 1.57 meters = 157 cm = 0.31 cm in 1:500 scale, that are 3.1 mm

B737 MAX8 -> 1.76 meters = 176 cm = 0.35 in 1:500 scale, that are 3.5 mm
Now, we are talking of 0.5 mm, half a millimeter but, if the mould must be almost perfect, the different engine of the MAX must be represented in the new mould.
About the landing gear, the extra 20 cm of the MAX are 0.04 mm, about half a millimeter even for the landing gear. Yes, we are talking of measures under the millimeter but with 2019 technology i imagine Herpa is able to represent these differences on the new mould.
These are the pics of the B737 MAX8 and B737 MAX9 moulds released by Herpa (i will post them tomorrow because they are too big).
We can see the winglets, the slots on the engines, the pointy tail cone. Impossible to understand if the engines are larger and the landing gear stretched.



















I hope to receive soon TUIfly Deutschland B737 MAX8 and United B737 MAX9 so we can check the models.

In all honesty, we haven't seen the sample properly so I'll be waiting with my judgement. I'm glad Herpa awaited the roll-out of the actual model this time (although they're still quite late to the party).. I'm eager to see how they'll catch up on the 737 MAX releases

This is the 737 MAX 8 mold done by Herpa. Still needing adjustments, though:

This is the 737 MAX 9:

(pics taken from vosen.de)

This is just a B737-800 mold with MAX wings, and I strongly doubt this will be the production version.

Re: Herpa B737 MAX mould.
 

While the engine diamater is probably to similar to tell just from a picture, their rear end has a different "rippled" shape, similar to what's used on a B787. So the new engines are also already on that sample.
Probably the modified fuselage itself (which DOES exist, as the pictures taken by Peter Vosen at the Toy Fair show!) wasn't ready enough for a production sample for whatever reason.

Quite interesting, that box on top (does anybody know, what that is?) seams not to exist on those MAX 8 already delivered to other TUIfly Airlines. However it exists on some 737-800 (like the Norwegian annouced for 05/06 2019).

The box on the top is to allow internet access during the flight: https://www.google.com/url?sa=i&sour...55407059101082

Here the fixed pics, from VosenWings.de:

Pointy tailcone, slots on the LEAP engine, different winglets, wi-fi dome...just to understand how the engines diameter is.

Re: Herpa B737 MAX mould.
 

Whats Herpas problem with too small Cockpit-Windows and too large nosegears lately? :rolleyes:

Re: Herpa B737 MAX mould.
 

Not just the nosegear! Herpa is having too much trouble with gear lengths lately.
DC-10, A320 family and A330/A340 have them too long. B757-200 have the MLG too short. And so on...

Re: Herpa B737 MAX mould.
 

Good design analysis by all above. Hope to see the 737 MAX in AA colors some time soon:cool:

Re: Herpa B737 MAX mould.
 

And there's the real one: D-AMAX. However: It doesn't have WLAN…

Re: Herpa B737 MAX mould.
 

It might be added later...
or maybe not :lol:

Re: Herpa B737 MAX mould.
 

Nop, that's installed before painting.

Re: Herpa B737 MAX mould.
 

Then let's hope Herpa will take notice and will release the model without it... :eek:
