I think the silicone would leak out of the gear diff then into the gear box.

Thanks for your support.........
use shims.. it would lock it, but not fully.

i tried using 100K diff oil (really thick stuff) but it lasted for a couple of runs only. its a pain re-doing your diff in that type of chasis so go with the shims of a ball diff which can tightened or locked.

What are you guys using to replace the friction shocks? Looks like Tamiya part number 49198 has been discontinued. ???

A lot of ppl are using the TRF shocks, but I use the super mini shocks (#50746) They are oil filled and have a shorter body than most.

Does this idea work..??

I tried the Heavy Duty grease..& it just gets flung out.

I`ve also thought about using "Silicon" as it has some give when dried.

i was using trf shocks but changed to super mini cva shocks with short springs, car handles better. i can now lower the ride height and still have travel in the shocks.

I`m going to give these a try.. they`re a 50mm shock so you will get the ride height & still have full travel...& don`t seem like a bad price either..

Default speed gears

Can I use a ta-o3 ball diff with speed tuned gears (integy or tobee craft)

Red line:
Either the Manta Ray or TA03 ball diff should work just fine with the Integy or Tobee gearsets.
Nova F1:
The Shoe-Goo trick works great to lock up the diff but according to the Tamiya folks this also essentially creates a spool, which is not made for the car and is therefore illegal for TCS races. Same thing with using a TA03 one-way diff in the front- not legal for TCS. Trust me, this has been tried before...both work well but don't make it through tech inspection. On the other hand, a really tightened down ball diff is perfectly legal- it just needs to have some discernable diff action.

i use the TRF flourines as well, and with the short springs, i can get ~3mm height either end, with the 60D tires.

of course, there are about 3 o-rings in each to adjust the droop, but it works just fine...

Then a little locktite on the diff screw might help...

Stupid question about the Tamiya bearing kit for the M03 (53348) What are the two aluminum shafts for? Are they necessary, or can I just buy some generic bearings since they're cheaper?

RE:Two shafts,are there 1 long & 1 short..? Yes they are necessary as they`re the shafts the gears spin on.

Alot of ppl swap these 2 shafts for the Tamiya Carbon Fibre Shafts to save on a little rotating mass in the drivetrain.

RE: Generic Bearings , There`s no reason why you cant use them just take the bushes down with you so you get the right ones
