Motors and warranties

[PaulRotheram]

Hi all!

not sure how many of you read other forums, but a while back i posted on the doughtyuk forum about a v2 Spashett motor i was having problems with, causing my car to overheat and go in to thermal shut down in 2/3 minutes of use!

after inspection i found a small peice of the arm on the stack was sticking out and i presumed this could be the issue. i tried a few different varients to resolve the problem.. different endbell, different can, different arm, different esc - different driver!

i had also found wear, and/or corrosion on the motor can see picture -

i sent the motor to helger to be checked over after contacting them with the issues. after about two weeks i received a package with the following note:

'missing piece of coating is of no concern, the damage to this arm has been caused by corrosion forcing the laminations apart, this is not a manufacturing fault. David has supplied a spare arm from his stock to help out though'.

now from my point of view, as stated on the note that the corrosion has caused the problem then surely this is a manufacturer failure as the protective coating on both the arm and stack has failed - as it has corroded! i can see no signs of the motor i sent being checked over as both the comm and brushes are in the same state as i left them before packing them up - worn from its last run.

i have been sent another arm to help, but i am not sure it is actually an orion arm, and it is definatly not a spashett edition.

New arm on the left, old arm which caused problems on the right

looking at the 'new' arm the comm is bigger in diameter than a regular V2, the 'grooves' are no longer in the stacks to aid cooling and this armature they have sent me is a 10x3, not the 10x2 i actually sent! there are also some indents in the coppers surface. (im not being picky here, but it is big enough to cause some loss of connectivity to the brushes).

im looking for some advice with the situation really, i feel it should of been replaced fully as the motor has failed, from my viewings the motor has not been tested and i have been given an incorrect armature and the wrong wind which i suppose was to make me feel better over the situation. I dont wish to actually run the motor due to previous runs with the motor it caused my car the thermal shut down in a very serious manner - possibly damaging most of my cars electricals .

The motor its self is about 3 months old, being used most weekends on the correct reccomended gearing by losi and helger 'factory' drivers.

so the question.. what now?
