If you mean the ballstuds, its a 3/16 nut driver. Im pretty sure that the pinion is a 1/16 driver. Hope it helps!

Pinion is almost always 1.5mm.
If you have the American imperial type pinions, they are often 0.050" or can be 1/16th as Andy said previously.

Most of my american pinions are 1/16th- I bought a full set when I started racing. (which reminds me, where can I get a bag of grub screws for these? I need at least 10 or so)

I replaced them with good quality RW pinions which are 1.5mm

RW do a pack of metric ones with the allen key for about £2, I think they might also do the 4-40 ones also.

1/16th and 1.5mm are almost interchangable as far as the driver. Ive had to use 1.5 in a pinch before, haha.

jimmy-I know a company from the states Robinson Racing sells extra setscrews.

Is the FastraxInterchangable Hex Driver Set any good? I've heard about some of those, for ex those from Turnigy, which broke pretty easily. Are Fastrax better than that?

[jaxx]

I have both metric and imperial sets of the fastrax drivers, I've had them since they first came out and I have not broken a tip yet!

[zagonielod]

Thanks jaxx! I'll probably buy one set than. I have to see which modul do I need. I have a Torche Pro and an Ansmann Mad Rat. Do you have any ideea which module are those screws? Metric or imperial?

[zagonielod]

Bought them today!
It is sooooo much better with theese in comparison to those small L shape hex drivers loooool
