You can tune a halo for more speed.
There are two important areas
to look into. The spring tension which is the time to load each
individual ball, and the motor speed which is the max consistant BPS
governed by the rotations of the drive mechanism.
Firstly take a look at the electric motor. The brushes are basicly the
little metal tabs that the wires are soldered onto. I have heard of
better aftermarket motors from the RC world which help, but you can do
better things with the stock motor.
When putting the motor into the housing do NOT bend the tabs in, the
best results seem to be with the tabs as far out as possible that stll
allow the motor to slide into the housing.
You can check for your motor speed by hooking it up and listening to
how it runs. You want it to immediately hit full speed. Some come on
and then speed up after a bit of time, and some don't sound so fast.
Often by bending the tabs you can hear a difference in speed.
Next you can get more force on the ball stack by modifying the drive
spring. DON'T just wind it twice, this can actually cause binding and
be bad. The best results seem to be from cutting approx 1/4 turn off
the spring and then bending out a new wire tab.
If you can get your hands on a set of springs and mod them by varying
amounts to get the best results. Don't mess with the springs if you do
not have spares, as you can end up putting too much force out for
Check which spring you have. At one point their spring manufacturer
gave them stainless springs which are not as good as the piano wire
ones. If you have a shiney spring that's the bad version. You want the
dull piano wire version.
Make sure the drive cone isn't binding. DO NOT over tighten the screws
that hold the motor casing and gearbox cover together. If you do they
can stick up a little and drag on the bottom of the drive cone. You may
not notice any difference without paint but the weight of the paint can
push the cone down a little making it bind.
Also bend out the ball detent with the beads on it so that it sits as
far away from the outlet and more towards the spring as possible.
Oh and get Z-code. It is faster.
If by doing all of that you still want to go faster... then you can
also maching up slightly larger diameter drive pulleys to go on the
motor. Don't go too crazy though.
Err... That's about it for now.
let us know how it turns out.
