yeah well problem is okay now..


just then, i think in the morning too


can't remember what i did


but i moved the brushes on the motor and it ran again


the steering would still work...but accelerating would do nothing...


but if you push the wheels and move the stick the motor works...the car wouldn't move when it was still..but when i gave it a kick it moved...


something on the motor jamming?

Probably a "hung/stuck brush". Grab their pigtail and jank them out a little bit (5mm) and then release, let them snap back in - that should get you going again.


Caused by dirt buildup in the brush hoods/tubes. Best thing is to unhook the brush springs and pull the brushes out completely. Wipe their sides clean and run a cotton bud into the hoods. For the business end of the brush (the tip), you can lightly run over them with a pencil eraser if they're dirty.


The brushes should be a copper reddy golden colour. If any part of them has gone BLUE, that means it has overheated and you should replace them.

No, the nearest truckie CB radios run on 27Mhz, others are very much higher up the freq scale.


One of the few reasons why Futaba sells 29Mhz radios here, they make them just for Australia. Not easy to find Futaba 29MHz gear anywhere else.





Besides... if you get interference... you'll be losing ALL channels, not just 1.

i have read the guide and i the brushes need replacing...one brush 'block' is2 times the size of the other



yeah i have put the motor back together...


the brushes need replacing...i push the stick forward but the motor doesn't move, but if i push the smaller brush in, the motor works but there are a few sparks...so hmm...probably need to get the comm straight again

man, youll actually find it quicker with a 21t pinion, or even a
19t...your motor for example would have about 30000RPM....with a 23t
pinion it would be more strain on motor to reach its peak...(about 95%
off RPM)...with a 21t pinion it will reach it quicker....and yet make
it feel faster...and less heat.....i run a 21t pinion on a 16t kyosho
mega motor...which i would say would have around....hmmmm
30000RPM...which is a fair bit...
