I had the idea to convert my Tamiya TT-02 either into an Short course truck or an Monster truck! (Note, this is not a TT-02B with bigger wheel) I don’t know if this is already done before but I give my take on it! My initial idea was to make it so that I can easily switch between the Tamiya TT-02 and TT-02 conversion one! But if I can find a cheap second hand TT-02 chassis, I think I will keep this one as a TT-02 Short course truck or a monster truck!
I also want to use parts which I have laying around from other cars!
Step-1: Lower arms.
First I had to widen the car to be able to fit the 1/10 scale wheels. I have done this by using the lower arms of the TT-02B. They almost fit, the front lower arms do fit but have a little space on it, so I think I will put a little filler ring in between! The rear lower arms are a bit to big so I will cut about 0,5 mm from the lower arm.
I also needed some longer suspension pins! They have to be around 46 to 48 mm long I think! I used 46 mm long pins (these I could find).
Step-2: Upper arms.
For the upper arms I’m using 2 different solutions, just to see if it works ok. In the front I’m using the camber adjustable Eagle front upper arm and in the rear I’m using the Tamiya TT-02 Adjustable upper arms. Of course I had to adjust them with longer turn buckles to make them fit!
How I assembled the upper arms, front and rear.
Step-3: Uprights and drive axles.
For the upright and steering cups im using the TT-02B B-parts Uprights. I only could get them in white but it looks ok. For the axles im using the Eagle rear TSD joint shaft + joint cup for TT-02B. I also use these rear axles in the front because the Eagle front axles are a bit to short!
Step-5: Front bumper
For the front bumper I used a Wltoys A9x9 metal Front And Rear Collision Plate (A580047). Buy it here! It’s easy to assemble it to the Tamiya plastic bumper!
I also upgraded the drive shaft [OP-1501] and joints [OP-1502] to aluminum with an High Speed Gear Set (68T) [OP-1500] and with ball bearings!
I’ve been using it for a few times now and I’m not disappointed at all! It’s quite fast and surprisingly strong somehow. On the beach I drove over rocks and hit rocks but it’s still ok!
There are a lot of upgrades possible for the Tamiya TT-02 frames! So little by little I will buy some upgrades to make it better.
- I definitely need a better servo and steering set because it’s to slow and there is a lot of space on the steering!
- New and better shock absorbers.
- There are steel diff gears and spur gear available, but they are quite expensive!
- For the rest some aluminum upgrades.
If you have questions, please let me know!
