Default reddish com?

this is a sign that the com has over heated. 1st thing to check is the gearing. the com will turn red if the car is overgeard. if you absolutly think that your gearing is right then most probably its your springs. normally what i would do is move to a harder spring.

just my .02

if the comm has overheated, then the brushes must be discoloured too. i've come across reddish comms too, but the brushes are okay, no discolouration. so does this means that the motor is geared right to the maximum??

the comm heats up faster than the brushes cause its not only metallic in nature but also of its rotating action like disc brakes in a real race car it glows red.

most probably since it hasnt heated up yet enough to discolor your brushes you are geard just right. try to install slightly heavier springs.

-if you have been using your motor for quite some time now you might want to change to new springs.

-if your motor is new and spring tension is still good try adding more tension by streching your spring more around 180* for the spring on the positive side and less for the spring on the negative side.

commutator
copper-yellow-orange-red-blue-purple. yellow is the color of the comm once it has started to over heat.

thanks for the advice,
i'm using team luna LU-85, speed version standup brush, less than 10 packs through it. by the 4th pack, i noticed the reddish comm, drop a teeth since then and so far so good.

Hello!

Will Putnam Blue Stock Brush and Putnam Green Stock Brush work with the 23T Yok LT and are they better then the yok stock brush?

What is the difference between the blue and green ones?

hi guys,

i know this was probably asked and answered before, but cant help but wonder, how do you minimize the really strong cogging effect of 23T motors. i ran a 23T last night and the cogging effect was so strong, it semmed like the car was braking whenever i released the throttle, your suggestions would be really invaluable, tanx

evaa.
Did you try with other motors?
Sometimes the problem arises from the motor itself.
I race 23t stocks and had never this cogging problem.
I am also using the same ESC ur using.

You can try softer brush springs and adjust the armature free play in the can.

Hope it helps

Which 23T Motor are you using that is causing this Drag Brake affect ...if it's a torque based one and it has laydown brushes you can do a few things but I will need to know which one it is 1st ..also if you only like using a laydown brush motor....and you want less drag brake...try using the RPM version they are much better off throttle....

Are the yokomo t-max LT and Mirage Prism (pink dot) essentially the same motors? I do not notice much of a differenc except for the packaging.

Also the Mirage RS2 , the 1 with one laid down and one standup brush hood any different to the pink dot with both laid down hoods?

What brushes do you recommend for these 2 motors?

The LT and Pink Dot are pretty much the same motor ..just different brushes and a bit softer spring on the - side on the Hybrid one..

as for the Mirage RS2 or Blue Star.... . It's one of my new favorites...it has all of the Power of a Laydown Torque Motor but does'nt have the high drag brake affect of a Laydown Torque motor..... on average I get about 20000 Rpm @ 5 volts & 5~7 apms of draw from the Blue Star.... and they like to be geared around 5.4~5.7 depending on the track layout and grip conditions
