Hello, I’m new to this page since today.
I’m designing and printing the parts to build a HEMMT A4 but with visible engine.
The model kit where these parts are going to fit is the kit from Italeri / Dragon.
Today I’m starting the suspensions, but I’m not sure If I’m going to design axles also or just the suspension alone and use the kit axles.
This picture is the engine with the side radiators, still need to make the fans and holes in the exhaust shroud.
It may be a function of the kit parts as opposed to what the actual dimensions are. To fit the axles between the arms and the frame, I had to extend the mounts and add taller bags. Here are how mine turned out.
The flat spot where the axles rest on is 20 mm from the top of the chassis, same as on the kit.
But I’m going to design the axles as part of the suspension.
That way its possible to use the drive axle from the front to be used at the rear to make a 3 axis rear.
Sounds good then. It looks like it will be a really nice set. Too bad mine is almost done. I just laid paint on it yesterday.
This suspension setup is not correct for the triple rear axle M1074A1 PLS.
From an earlier post on the topic.
The M1074A1 PLS still uses the same rear suspension set-up that was on the original M1074 PLS. I found this on the Oshkosh PLS page.
“All PLS variants have the same rear tridem unit which consists of a single Hendrickson-Turner air-sprung drive axle (3rd axle) and a Hendrickson RT-400 leaf-sprung AxleTech tandem (4th and 5th axles) on which the rearmost axle contra-steers. On PLS A1 variants the front AxleTech/Oshkosh axles are sprung using Oshkosh’s TAK-4 fully independent coil spring suspension. The original PLS had a Hendrickson RT-400 leaf-sprung tandem front suspension.”
On the engine area parts, I would do the individual parts to add to the kit platform. I would leave the placement of them up to the modeler. This would also allow them to be added to the much better detailed Trumpeter HEMTT kits as well.
Size-wise, the Italeri and Trumpeter kits are identical. On my current M978A4 build, I am mixing parts from each to get what I am after. I also mixed them on my M1074 and M985A2 builds. So, your parts should fit either kit just fine.
