LOSI SHOCK SET UP & PISTONS FOR AC S4

BenH

Here is some great info for losi shocks -

1st - Losi Numbers for Pistons. Higher the number the smaller the holes, the harder the shocks - (More Pack.)
#60 (Natural)
#57 (Black)
#56 (Red)
#55 (Orange)
#54 (Blue)

Q – How should I fill my Losi Shocks?

1 – Fill the shock body up to where the thread starts
2 – Leave for a short while to let any air bubbles get out
3 – Get the shock rod/piston/cartridge and push it all the way in (so the ball cup is up against the cartridge and the piston is fully extended)
4 – Plunge the piston into the oil slowly until the cartridge meets the body.
5 – Slowly screw the cartridge into the body holding the shock at ~45 degrees; you will loose some oil at this point.
6 – Tighten the cartridge using your normal tool(s).

1 – Fill the shock body up to where the thread starts
2 – Leave for a short while to let any air bubbles get out
3 - Get the shock rod/piston/cartridge and pull it all the way out (opposite to the above, the piston should be against the body with the cup fully extened)
4 – Slowly screw the cartridge into the body, tighten all the way and back it off about ¼ of a turn.
5 – Slowly push the piston all the way in with the shock held at ~45 degrees; you will loose some oil while you are doing this.
6 – Tighten with your normal tool(s).

Some Q and A's found: -

Q - Can someone explain to me how you get to a drilled piston ie. 555 or 666. How are these numbers made up? And what size drills you use to get there.
A - Losi pistons are in 'numbers' as well as colours they are as follows
#60 (Natural)
#57 (Black)
#56 (Red)
#55 (Orange)
#54 (Blue)
This number also relates to a drill size.
Whever people talk about a standard piston in number they would just use the 2 digits or the colour.
If they talk about a drilled piston they will use a 3 digit number, something like 556 or 566.
What it is the last number of the 'standard' piston numbers, notice they are all 5something so that does not matter
so a 556 piston would have 2 holes in #55 and one hole in #56
a 566 piston would have 1 hole in #55 and 2 holes in #56

**Tip From Richard Cree**
The number as Chris says relates to an imperial drill size, bear in mind the bigger the drill number, the smaller the hole.
Another thing to consider is a drilled 555 piston will have a slightly different size to a moulded 555 piston, for this reason I always used drilled pistons, even if they are standard versions available.
This really is very fine tuning, but once you get the hang of it you will find the jump between std pistons to be immense.
