My endbell has also cracked, this time around the top right screw. Nothing serious, just a result of hard and fast outdoor racing. I also managed this, and this is a bit more serious!:

At what point would i need to switch from 16 gauge wire to 14gauge?

Is 16 sufficient for Lipo 4300 in an oval car?
I have previously asked and reto said that 16gauge was sufficient for 4cell 4300, but now I have switched to Lipo

If by the word "endbell" mean only the plastic cap then you just overtight it. These 3 screws don't need to be very very tighten cause only keeps the timing at position nothing more.

but it's very interesting if you cracked the other piece of endbell and i would like to see a pic!!



this thing with the "armature" ( magnet) is just a manufactire problem. a friend of mine managed to break the axle at the point that the pinion locks

TCs run out but it's only a matter of few hours (LRP distributor is very close) to get more so don't be dissapointed when you see Out of stock

For off road, do you find a problem with dirt getting into the holes for the mode switches and leds? Do you cover them with tape?

We had a few rotors go at the TITC, Reto advised that it was due to getting too hot at high rpm, we replaced the rotor and added a motor heatsink and all was fine.

This should be an issue with previous motors and not sintered magnets!!

I broke 2 magnets , because the same reason as Reto told you , but it was 5 star or 5,5T with no sintered magnets!! And it was also prototype motor.
After that they sent us sintered magnets and everything was perfect!!

This is due to the fact that sintered magnets gives more torque and Less RPM's.
Previous magnets were broking due to hi RPMs and not temp!! even if a magnet has 300 celcium degrees won't broke , but it can be broken cause of extremely RPMs even if it is cool enough

I would of thought it was oposite... arent bonded magnets weeker? If that is the case they should have less torque. I also thought that bonded were inherentely less reliable because of their constrution, hence the overheating problems with those rotors, but i guess im wrong...

Yeap itis right that bonded are weaker as a material , but if i can explain it right it has more torque than a sinterd magnet , that's why they using a diff gear ratio!! maybe i am a little confused so i will try to think it and explain it better later with a clear mind!!

Sintered has more torque and less RPM, that is why we have to use bigger pinion, to make more RPM.

Sintered does not break as easily as bonded because the material is stronger.

That's right , it is exactly the opposite from what i said before! Sintered=More torque and less RPM , it was a misstranslation from Greek to English!!

but i don't think that bonded brake easier because i remember that when i raced with bonded i used 2 degrees of autobrake and now with sintered 0 degrees for being equal to a brushed motor. But i may be wrong because i also ued different spec speedos!! Sphere comp-matrix 2007- TC spec
