those are the normal diff plates, they don't lock on to the outdrives. anyway as far as i know of, there isn't any. 3racing made a set of outdrives and matching diff plates that can lock onto them but unfortunately not to the tamiya outdrives

I know RCMarket used to have a "D" type diff washer that could be used on the Tamiya outdrives, only seem them listed once, and they where out of stock at the time. I haven't seen then since, but maybe RCMarket will see this post and he can shoot you a link.

I bought the 3racing diff set and it seems nice. Builds like a normal Tamiya diff and feels pretty good too. Overall it is nice.

Just wish someone would anodize them blue...

Default Hara Springs Measured

After sitting on my desk for a year - I finally got around to measuring the Hara Springs. I measured two springs and took an average.
I'm impressed - these spring actually measure very close to the rating on the package - that's rare in the RC world.
The graphs show that the springs are completely linear (with best fit R squared value between 0.9988 and 1.0000 for you technical types).
The measurement was done with a Chatillon 10 lb load cell and a test stand with accuracy within .001".


Hara Springs
66961 Yellow
published = 12.88, measured = 12.97
66962 Silver
published = 14.00, measured = 14.37
66963 Black
published = 15.12, measured = 15.44
66964 Purple
published = 16.24, measured = 16.41
66965 Pink
published = 17.36, measured = 17.57

Has anyone tried the new short black springs item code:42168 (red, yellow, blue) from Tamiya on asphalt? Are these any stiffer\softer than the original red, yellow, blue springs?

Has anyone tried the spec r gear diff? I'm thinking on getting one instead of rebuilding my ball diff.

I have built mine but haven't had the chance to run it. A couple of things I noticed in the build...

All the internal gears are plastic which should be ok in theory. However they are moulded and have some sink marks on the flat side of the gears. In fact the instructions ask you to "polish" them on some sandpaper to ensure a flat surface...

The shaft the small pinion gears ride on is also plastic and moulded as a one-piece cross-shaped part. In other gear diffs, there are normally 2 shafts that cross over each other.

It will be interesting to see how durable it is with the plastic internals. It might be ok since everything is swimming in oil anyway. Other than that, it is a pretty standard issue gear diff. It is nice and smooth. Can't wait to test it out soon!
