Drilling the pistons

[juergen_jl]

Hy,

in several set up sheets, the pistons are "drilled" to achieve a greater diameter.

As far as I could "find out", the standard diameter in my CAT AERO and in my Cougar KF of the holes is: 1,5mm. (at least this was the diameter for which i could feel some "resistance", 1,4 was too small, 1,6mm show "massive" resistance).

I am not a pro driver, nor is my son (14, but he is racing for several years now). But a good set up is always a great thing, so I decided to go for some "drills" in this dimension.

I have always used (in my former CAT SX, SX2 and SX3) the pistons with 2, 3, 4, 5, 6 holes), but I found, that the 3-wholes worked best...

Anyway: I just want to let you know, that i found a supplier for drill bits. CORE RC offers a set for drill bits until 1,5mm (RC233), this is out of stock in germany. (CS-electronic). And, unfortunately this does not help

My supplier offers all drills, like, 1,5, 1,6, 1,65, 1,7, 1,75, 1,8.... if you want in a very nice box....

I don`t know, if i am allowed to publish the name (I have nothing to do with them) or to set a link to their online shop here. Let me know
