Tamiya CR-01 UNIMOGPosted by xilsoe May 16, 2016 15:27:25 By lucky chance I found a snorkel for a TAMIYA U900 UNIMOG on ebay. I immediately purchased it as I have always wanted to have snorkel on my UNIMOG as the ones used in the Danish army had snorkels.
I was thinking I would never find a ready made snorkel, so I thought I would need to make one myself but what do you know? The next thing would be door handles
I have cut mine a little shorter as I think it is too long and the pipe lengths aren't exact as wanted them. Then I have fixed it at the top to resemble the original. I made this fix from a ø1mm brass rod where I cut a thread and then some M1 brass nuts and washers.
To fix it at the base I used the original fixing. Here I also cut the extending rod on the snorkel to length and then drilled a 1,6mm hole for the original screw.
Here are some pictures of the snorkel installed:
I still need to paint the fixing. I'll do that when I have something else to paint in the right colour.
Tamiya CR-01 UNIMOGPosted by xilsoe Feb 21, 2016 20:53:28 For some time I have wanted to add a sound module to my UNIMOG. From my Leopard tank I know how sound adds to an RC unit. After spending some time researching, I finally decided for a beier-electronic USM-RC-2. Link to beier-electronic.This was the only sound module I could find with UNIMOG U900 sounds available. Furthermore it has a build in amplifier so I wouldn't need a separate amplifier.
For speaker I thought that the ones that were offered along with this unit were too big. Further I wanted a cabinet so I went on ebay to see what I could find. I found this music angel that is about 50mm x 50 mm x 50 mm. That wasn't too big to go inside my UNIMOG. My intention always was to take the music angel apart and only use the speaker and the cabinet.
When I finally got my music angel and took it apart, I learned that the speaker didn't meet the required specifications. My solution to this was to get another music angel and take that one apart as well just to use the speaker. Then I coupled the speakers in series and they were up to the required specifications. Getting another speaker also solved my problem of sealing the other end of the cabinet. So now I have two speakers in the same cabinet. The only problem with having two speakers in the same cabinet is that the speaker's magnets are pushing apart. To keep both speakers in the cabinet I put a strip around the speakers and cabinet. That will also make it easy to take the speaker and cabinet apart if I need to do so.
In my view the USM-RC-2 is a very advanced piece of electronics with a lot of options and controls available. I am not really using much of what this unit can do. My Spektrum RX and TX are too limited to allow me to do much more with it. If I was to do more, I would transfer to my Futaba RX/TX. To program the USM-RC-2 a windows program is needed and I found the data cable very helpful when finding out why my sound unit didn't do as I wanted it to.
As I mentioned before I am not really using all the things this unit can do. I am just using it for sound. I have set it up so the engine sound will depend on the throttle. Then I turn the sound on and off when I turn the lights on and off. So lights and sounds come on at the same time.
Here are some pictures of my modified UNIMOG's interior:
I know pictures don't say a lot about audio. So I intend to make a video that demonstrates the audio.
Tamiya CR-01 UNIMOGPosted by xilsoe Oct 03, 2015 13:59:43 After buying some different window vipers I finally found out which would work: RC4WD Mojave (Tree Z-B0025). Unfortunately only one of the vipers in the tree can be used, so two kits are needed. It is not a perfect fit right away. The blades have to be shortened and I did some twisting of the viper arm. To do the twisting, I had to heat the plastic in the places I wanted to make a twist. Careful with the heat as it can easily be too much. To capture the looks of the Danish army UNIMOG I had to paint the viper arms. Here are some pictures:
Now I am still looking for a way to make door handles and a schnorkel
Tamiya CR-01 UNIMOGPosted by xilsoe Jun 10, 2015 20:37:10 When ordering some parts for my TAMIYA Bruiser I also ordered a winch for my UNIMOG. When I selected the 3-Racing CR-01 winch I thought it would go right on. Especially after I ordered the CR-01 mounting plate.
To mount the winch I bought an extra CR-01 bumper and cut it so I had somewhere to mount the winch. Then I cut a piece of aluminium, drilled some holes for mounting the winch and the cut bumper arms. To have the holes placed precisely I used my PROXXON coordinate table with my drill stand.
When I was done with drilling, I used my metal sheet bender to bend the ends of the aluminium piece so it could be mounted on the cut bumper arms. Then finally after this I replaced the winch hook with a RC4WD King Kong hook as the 3-Racing one looked awful.
Tamiya CR-01 UNIMOGPosted by xilsoe Sep 27, 2014 20:08:20 Today a new set of propeller shafts arrived. I decided to go with the TAMIYA carbon steel propeller shafts. An important property being that they are black and won't stand out. The TAMIYA propeller shafts are manufactured well and precise. They are a little advanced to put together but nothing to worry about. When ordering beware they come in two different lengths. One of each length is needed to replace both propeller shafts.
When the shafts have been put together replacement of the old nylon propeller shafts is straight forward.
Tamiya CR-01 UNIMOGPosted by xilsoe Sep 22, 2014 20:48:30 This Saturday my UNIMOG had an accident, where it tipped over and the rear wheel set became blocked. The result was that the rear propeller shaft broke. See the pictures below. I must say that I am quite impressed with the force that the motor and gear box delivers. Deforming this axle like that is not something you do with your hands. Now I ordered the TAMIYA carbon steel propeller shafts for the CR-01 chassis. These will most likely last. The bad thing is that my UNIMOG is broken until I get the spare parts.
