  1. Thanks for clarifying. I might fit some other suspension arms instead then. From Tamiya site: From Tamiya's description, I guess this will improve power distribution to the wheels only. I haven't seen any comments of this Hop Up on the forums, probably not frequently used.
  2. I’ve been thinking about installing the Tamiya WR-02 Assembly Universal Shaft #54394. The specs show the shaft is 39mm, 4mm longer than the standard WR-02 shaft at 35mm? Other than better cornering stability (rear wheels would be 8mm wider), any other noticeable improvements? Anyone have experience installing this Hop Up? Trying to decide to pickup or not...

    So, What Have You Done Today?

    Nice! Perfect to my eyes. Did you use a loupe?

    Did some masking...
  5. Thanks. I didn't realised 54496 contains screws, nuts etc.. that would be handy.

    WR-02CB straight steering

    Thank you for pointing out the toe rod ball ends. Indeed they should be on the top side. Also the additional information which I think is valuable when setting up any car no matter what chassis. 🙏 Below is a pic before I installed the the Aluminium Hub Carrier. I must have installed them incorrectly after I installed the Aluminum Hub Carrier Hop-up. I have no idea why I didnt pick this up earlier! As wolfdogstinkus mentioned in another thread could be my ageing. :-) I'm going to correct this first, check rod-tie lengths before taking the car out for a run later. btw I also have Tamiya 53345 - Toe-In Rear Upright installed at the rear.
  7. I'm looking at the driver part numbers to complete my Wild Willy 2 Gumtree purchase. I noticed there are two parts numbers that seem to be for the same parts tree. The description and photo look the same. Tamiya 0115256 Parts L - replacement sprue from the kit? Tamiya 54496 - additional driver sprue?

    Good point as in 1:1 scale. Cars naturally track straight in real life. I will tighten the wobbly front wheels more with spacers as ThunderDragonCy suggested. I re-checked and indeed it does lean back slightly. Thank you for confirming what I was suspecting. I have extended the tie rods to 40mm. Initial testing in the house driving down the corridor, straight line seems to have improved a bit... I will take the car out this weekend for a run on the tarmac. Also order some spacers and continue tweaking. Really appreciate all the input fellas! :-)

    Brushed motors and 'sparks'

    Thank guys. Great advise and something I can follow going forward.

    I guess small sparks, maybe nothing to worry about? Untitled.m4v

    Typo: The manual did not state toe-out but it looked toe-out to me after I assembled everything.

    I'll give the 4mm a shot (Tamiya 54573 0.75mm Wheel Spacer) and report back later. It will work out cheaper than purchasing the 10mm hexes (Tamiya 5461) and the Tamiya 50808 TG10 Long Axles (good tip BTW!). The manual did state toe-out but it looked toe out to me after I assembled everything. Will definitely change to toe-in this weekend and take the car for a run. Come to think of it - I did install the Tamiya 50473 - Hi-Torque Servo Saver and the length was slightly shorter than the once included in the kit. Maybe the stock tie-rod lengths of 35mm needed to be adjusted because of this. Yes, the hub carriers have 8 degrees of caster and are installed correctly - they lean forward slightly (will double check - but the way it was designed it was hard to install incorrectly).

    WR-02CB straight steering

    Thank you for the response and tip regarding using the 5x7 Schumacher Speed pack (0.4mm) shims. I had a look on the Tamiya Japan website under WR-02CB chassis and they list Tamiya 54573 0.75mm Wheel Spacer (Blue/8 Pcs.) which is probably very similar. I might give that a go. The item I suggested Tamiya 54610 OP.1610 Clamp Type Aluminium Wheel Hub is not listed as compatible with WR-02CB (only WR-02). I’ll definitely adjust toe in first and will hunt for an app (good idea!) to measure the toe in angle.
  14. I am trying to get my WR-02CB to drive in a straight line. Well…as much as possible with this chassis. The trim/servo saver has been centered and both tie rods set to 35mm (slightly toe out) as per manual. In addition, for the front the following hop-ups have been installed: Tamiya 50473 - Hi-Torque Servo Saver Tamiya 54587 - Aluminum Servo Stay (WR-02,GF-01) Tamiya 54661 - Aluminum Hub Carrier (8 Degree) (GF-01, WR-02) I’m looking to adjust the tie rods so the front wheels either be straight or even slightly toe in. Been reading various threads on TamiyaClub and there was mention the following might help: Tamiya 54610 - OP.1610 Clamp Type Aluminum Wheel Hub Will this take the slight wobble out of the front wheels?
  15. When I look in the motor on the bench I can see yellow sparks when its running (forward and backwards). Some people mention that if there are sparks either: motor has not been ‘run in’ brushes have worn out (replace brushes) motor is dirty - run it in water to clean (?) motor has debris inside - unassemble/clean/reassemble What is the general consensus on sparks being emitted from a brushed motor while it’s running? Personally, I don’t see any issue. It’s only a backyard runner and motor has low runtime. I guess as long as the sparks are not flying out of the motor or any smoke, it should be alright.
