there is a number of nicely build TT02B’s buried in the build threads it may be worth looking at those as well.

The GPM gears had some tolerance issues with the first batch, but I haven't read of anyone having any issues with more recent batches, so since they are easier to find than the DF-02 diffs and require no modification, this would be my recommendation. des tausendfach beliebten Plasma Edge. Dank einfachem Aufbau und wartungsfreundlichen Lösungen eignet sich das Chassis auch für I think i will follow your advice about spending money in another kit but I don’t know which one. Db01 is not a very old one ? Includes Tamiya TBLE-02S ESC (electronic speed control) Capable of running sensor brushless motors and brushed motors alike. (21.5 Turn BL motor limit) (23 Turn brushed motor limit). I would avoid GPM, 3racing or Yeah racing buggy dampers they are all pretty terrible and won’t really be much of an upgrade over the Tamiya plastics, and will probably be less reliable, it’ll just be wasted money. Visit my buggy damper thread for the lowdown on Tamiya dampers.

I confirm the ball bearings kit is NOT the same up to a certain point. Indeed, the size of the bearings for the wheels are slightly smaller than the one for the TT02B. Thus on my Tt02, I was only able to install the driveshaft and the diff ones. The TA07 and TB05 appear to be different to the earlier TA and TB cars. They haven't been released as kits, rather the base model is the Pro. This comes with TRF dampers but no body. The R is released later with more hopups. The TA07MS has been released now which is basically a TRF car. I expectvthe TB05 will get the R morel, but the TB Evo 7 is basically the MS version so not sure if there will be a TB05MS. The earlier TA and TB cars also had kits which had CVA dampers but were an alternative to the TT car as a starter kit. Motor. I see heat sink and motor mount. Both of them will be too expensive. Which one will be better? That to me sounds like the ring gear on the rear diff which is the major weakness in the TT02B drivetrain. It will keep going for a while yet if its intermitrant. You have a few options.

I am not sure if I will be able to use the last one. Shafts I have seems to be little long and I am not sure if they will not collide with wheels. While the TT02S is better with different suspension, the R's are just the base TT02 with some hopups. I'm not a fan of the TT02 other than as a great basher or for the entrt level racing class.Buggies have larger tires, thus requiring higher (shorter) FDR to achieve the same speed. The Plasma Edge II comes with ~88mm tires.

i already broke a servo, so is the servo saver a must ? Or another servo with more torque? Which one ? should I care about the spur diameter? I already have an adjustable motor mount so I assume no problem putting a smaller diameter spur but is the diameter an issue here?

Shaft-Driven 4WD ★Front/Rear 4-Bevel Differentials ★3-Piece Steering Tie-Rod ★4-Wheel Double Wishbone Suspension Kit comes standard with 22T pinion + 70T spur, for a gear ratio (or Final Drive Ratio, FDR) of 8.27 I really recommend Tamiya cutters. Quality is very high and makes work really easy and fast. Do not use those cheap cutters. Bathtub-type frame has longitudinal battery and R/C mechanism placed flat for low center of gravity. Diffs ready. I mounted almost all parts on drill and sanded edges, to remove all imperfections and excess of material. Probably it will not make any difference, but at least I know that I done everything I could. Somehow, I think that big two gears inside diff need some sanding. They touch diff body and should be perfectly smooth. Straight from box, they have quite a lot material on edge. It is like plastic "hair" on edge.
