6-wheeled Sd.Kfz.231 – Beginning of Wehrmacht reconnaissance

[Panzerjaeger66]

Usually I’m designing tracked RC vehicles, but sometimes I switch over to other genres.
Since a very long time I wanted to have a 6-wheeld recce car Sd.Kfz.231 and after WPL/JJRC released their trucks, it was possible to use some parts of their chassis.

Here are some pictures out of the design phase.

































While designing with WPL axles first I saw some problems and switched to JJRC...









Base is the chassis of the JJRC Q60 (WPL B16 isn’t possible to use because of its different rear axles).





Some parts of the kit:

I’m loving this, looks awesome
If you ever consider selling the STL’s I’d be your first customer

That would be a perfect candidate for 1/6 scale. I can see the little wheels turning in Wayne's head all the way from here.

Great. Very Interesting challenge. I’ve done a couple of adaptations myself and it’s real fun, experimenting and improving with each model. The length of the axles and choice of tires can be an issue when luck does not offer a perfect fit from the start. I understand your choices. I am surprised you seem to create your own gearbox upgrade. There are quite a few cheap upgrade options available on the market with 370 motors, including the one with high/low servo shifting between crawler mode gears and high speed. I was recently surprised by its capabilities. On a vehicle with a fighting turret like this one, choice of electronics is also important for turret/gun action and also servo steering. I’ve found that the Clark TK-40 worked well on the Cadillac Gage V-150 and the TPz-1 build.
I will follow your progress and ideas.

Wayne, because I'm working exclusively with Chris https://www.ludwigs-hobby-seite.de and Lukas https://www.fertigungswerk16.at/modelle/ this won't be happen; I'm sorry

Uh, because the kit is all 3D printed, the lower hull would be approx. 1m long in one piece; that have to be a huge printer...

Louis, I see you checked the posted pictures accurately!
You're right, the length of the axles have to be reworked (a little) but overall they are very good to use. Because I'm working with Lukas who is very experienced in 3D printing (see his homepage) tires and other stuff is no real problem, also the gear box. The hull is very tiny and to find a fitting gearbox needs more time than to design a exactly usefull one. The gear motor I'm using is an 370.
I'll check the TK-40 if it would be working for this model; for now I've planned to use the WPL Sound Set V3 with extra connections to motors and maybe using turn light for gun flash, but let's see...

Best regards,
Freddy

Why to use those horrible electronics in such a wonderful and unique vehicle? I do not get it...

[Panzerjaeger66]

I'm very bad in electronics so I've to use what's standard available. I have no idea to use a tank board for this kind of steering? The only board I have on hand is the HL Tk 5.3 would this be working?

in short: No

Hi Freddy,

Your ability to design and fit mechanical parts in the tiniest of space is what is most important.

For electronics, its a personal choice and everyone uses what works for them. If i was building this combat vehicle and i might, i would continue with a tricky combinations of TK-40 functions and 10 channel receiver configuration where;
- Motor connected to TK-40 right engine port with vertical stick control and engine sound
- Steering servo connected to an available channel on receiver and assigned to one of the rotating knob as a driving wheel
- Turret rotation 360 continuous micro servo connected to TK-40 turret rotation servo port
- Gun elevation micro servo connected to an available channel on receiver and assigned to one of the rotating knob as elevation control
- MG34 machine gun with fiber optic/LED connected to TK-40 MG1 cables with mg flash and sound, assigned to a switch
- 20mm cannon with fiber optic/LED connected to TK-40 MG2 cables with mg flash and sound, assigned to a switch
- Head lights and tail lights with TK-40
- Small 2 cell 7.4V battery

Its one of the possible configuration but as you mentioned Freddy, its a narrow vehicle and available interior space is surely an issue. Its hard to realize the interior space left available for electronic units, turret rotation wheel and for running wires until the hull is built and we see what's possible.

Thank you for creating this vehicle.

Hi Louis,
thanks for you detailed explanation about the electronics you'd use, but I have no clue to do this (for now). Maybe later if I find a colleague next to me who will do that for me.
So, maybe you will show us later what's possible to do with this kit
