    Just had a look at the link. +/- 0.1mm is a lot a error for turning on a lathe, especially an industrial cnc.... 

    Thing they are covering themselves. Parts Ive had from them are accurate and Ive used as bearing surfaces.

    I don't know if you are still working on this, but the Ball diff from the SV2 (which is compatible with all the cougars, drop in replacement for the gear diff you guys are using ) can have 'long' out drives. Its compatible with all v2 style ball diffs ( so the latest v3 is not). might help the short fall in the dog bone length? I think its U3750 and U3751.

    Interesting. Thanks for the info. Do you know if there are long gear diff outdrives too? Or just the ball diff...?


  3. Wheels are nice and I like the blue, not sure about blue decals on the blue body tho, the colour is pretty indistinct.

    Also, i think you need MORE POWER! Looks like it could handle a fair bit more and you could clear those doubles.

    Great job tho.

    Its exactly the same geometry. only gearbox and arms turned around. Even the parts are original, the tower is just SLS printed but sames dimensions.

    But yes I agree, probabley movint the upper mounts for one hole to the center.

    For any case, I made this bumper to prtect the carbon chassis.

    Must just be a perspective thing then, the shocks look really straight. Nice bumper! 


  5. Changing both pinion and spur achieves the same thing net as changing only 1 of them by twice the amount - in terms of ratio not tooth count - BUT takes up more space. So in a cramped layout it can be good to have options for both to change.

    With enough space there's nothing stopping you from fitting a 70t pinion :)!

    Now its like this original DS can run 0.4module 20-31t pinion gear with its original 126t spur gear. This will give you a FDR from 12.6 to 8.13 .
    The 48dp 87t spur takes 22-30t pinion. Gives you a FDR from 7.91 to 5.8 .

    Both versions will cover the whole range. What do you think about this solution?

     

    Tom - You sure on those calcs? FDR range should only change marginally by a change in pitch. (you might get a tiny bit more or less at each end of the range due to slightly more/less clearance from one pitch or another).

    Dont see how changing pitch would take you from 8.13>12.6 to 5.8>7.91 - FDR as long as gearbox ratios stay constant is basically just comparing the size of the available pinion/spur circles.


  7. Ive used them on a few repro shells. Pretty good.

    You need to make sure ALL bubbles are out or either youll get bleed through under the decal or youll get visible gaps from above.

    Also I think it tends to look better with light coloured shells as there is sometimes a small amount of white edging at the decal edge which can be noticeable with dark backing.

    For resilience they are great and also much easier to clean down the shell as the surface is completely flat. Great for a runner.

    I know what you mean @Ann3x but it’s a fair question for @Collin to ask ?

    I’ll stick my neck out and suggest the TFE is prob the best out of the box, off road racer Tamiya ever released outside TRF ? 

    But that doesn’t include hopping up other NIB chassis - where you could do the same, if not way better, for way less money ? Especially if involving unloved TRF

    What seals things for the TFE is hardly anyone could apparently afford it - so similar to the original Avante ... only this time Tamiya reacted quicker,  culled production faster + fewer numbers were available ? 

    The TFE isn’t a racing epitome imo - it’s a collectors‘ limited edition ... and let the flood gates open 😂

    Was just a joke. Me and @Collin know each other well and we agree on most things!

    Back to the "serious" topic.... Mostly for me its because the Top Force in Evo livery is just a gorgeous shell, the way it fits so tight around the front gearbox, how low it sits and the orange contrasting of the decals and grey. Beyond the looks there is also the sheer excess of the original car (wasnt it something insane like £600 originally?) with silly, excessive upgrades included like Ti bolts, printing on the Carbon chassis etc etc etc.

    It is just a lovely car to look at and the excess made it unattainable (at least for me.... then.....).

  9. I also had a long attempt to make a slipper spur (for a Topforce actually). In the end found this as a simpler option: https://www.modelsport.co.uk/carisma-m40dt-slipper-pinion-set/rc-car-products/381157

    As you say its VERY snug fit for any useful spur based slipper design. It's probably possible but will have some inherent issues i think due to the spring throw. Ive come to believe a slipper pinion is a more universal option for older buggies.

  10. I've got one. It's good fun.. 

    Got it for my kids. It's not really a crawler, diffs can slip etc but it's good fun around the garden. Wheelies a lot and is solid enough to crash a bit. 

    The body is closer to the QD md, not the normal version.
