Shimming A Frogs Differential.

[Saito]

The old hex-headed half shafts had a habit of rounding off causing them to slip in their cups. I never encountered this on stockish Frogs though. It seemed to be more prevailant on the Blackfoot series of trucks due to the extra load incured by the oversize tires.

To be honest, I think tamiya is becoming a little lazy with details like this. Most tamiya cars have a weak point it them somewhere that could be fixed by tamiya so easily if they wanted to. I think tamiya should get there act together and put it right themselves so we do not have to modify our cars to make them work. Am I the only one who feels this way? (Rant over)

Just a thought but will a frog, after these mod's, be able to handle a ezrun?

For what it's worth, my re-re Frog has been totally reliable, and never had the drive shafts pop out, but my original vintage Frog seems to self destruct every time I run it, including the drive shafts popping out. So Tamiya must have done something right on the re-re!

Well... Yes and no. While some cars' "quirks" cause me no end of annoyance (with bump-steer topping my list), I don't mind them so much, especially in the re-re's. Remember, when the Frog first came out, it was state-of-the-art. It was a giant leap forward from the SRB series. Yes, it had some problems, and the aftermarket jumped at the chance to offer solutions. Then, the RC10 came out, which solved all of the problems with the Frog, but had its own little quirks. So Kyosho topped it with the Ultima. And then there was the Losi JRX series, and XX and XXX and B2 and B3 and B4. Each design ironed out a few problems from the last, made it possible to turn a corner a little bit harder, shaved a hundredth of a second off a lap time.

But as far as I'm concerned, this clinical approach to "improvement" of a design has engineered the soul right out of the cars. The fact that these models have been re-issued in more or less their original form shows that people like them warts and all. Complaining about the efficiency or reliability of a 25 year old design is sort of missing the point. It's like getting into an old Alfa Romeo and complaining about the lack of cup-holders. It has a vibe that can't really be added into a new design, and with that vibe come some little personality quirks. If you want something that works perfectly right out of the box, don't buy a vintage re-release.

It is a bit irritating that they changed the driveshaft design (which never had a failure on my old Blackfoot) and left the differential gears alone (which stripped out at least twice that I recall). But hey; at least there is a way to fix it.

Something tells me I won't be able to resist the siren-call of a re-re Frog or Brat much longer... You guys really have me jonesing for an ORV chassis.

this tickle your fancy for a frog/brat?
