Set-up help
 

Just bought myself a nice set of Ghea 10th tapered piston from P-Dub racing. They are for my xxx-cr and the car will be run on grass. What size do i need to drill the holes and what weight oil will be best? Thanks in advance,

Jamie.......

no need to drill them jamie, they have holes in them??
I use red all round with 35 front and 30 rear

Ok, just received my Ghea pistons (GHEA3075) and they have 3 holes in them which are 1.1mm.

Question is, do i need to drill these holes bigger, they measure up a #57 which is a black equivalent. But most UK drivers seem to use red pistons which i believe are 3x3/64 holes, do i need to drill mine out to the same size?, or just run them as they are, if so, what weight oil do i need to run front and rear?

Jamie......

What colour or piston number does it say they are on the pack mate?

Just says GHEA3075 and 3 x 1.1 and are black in colour.

ghea3075 are the black losi pistons mate.
these are the red ones Ghea 3078 - Losi Red (still black in colour)

Oh, i got the black ones as they were the only ones listing as tapered which ive been told are better on bumps.

*EDIT*, Andy, ive just realised that ALL the ghea pistons are tapered right? DUH brain here. So could i drill the holes out to the same size as the red ones, and hey presto?

I believe black are 1.1mm and Red are 3/64, either way i got both drill bits here?

Yeh, you could drill them, but then again you could just get another set!!:thumbsup:

At £15.99 a set, i think ill be using my #56 drill bit.lol

Cheers for your help Griff, but you may regret helping me if i beat you next weekend.......although i very much doubt that no matter how good my car is.LOL
