I'm not sure whats going on here, hopefully someone can help?
There is a bit to explain, so please be patient and read on...
I've got an LRP Sphere Competition TC Spec ESC (2 of them) and an LRP Vector x11 13.5T and LRP Vector x11 3.5T brushless motors that arent working, no matter what combination of ESCs or motors I am using.
The first ESC ran fine for a few months with a 27T brushed motor. I then swapped it out for a Nosram Dragon 13.5T brushless (was all I could get off the shelf at the time and I needed a motor) and it ran fine for several weeks. I then swapped to a new LRP Vector x11 13.5T brushless motor (as the Nosram wasnt performing how I wanted) and here's where the problem started.
When I accellerate, the motor makes a beeping/whining noise. If I hold the throttle on, after about 2-3 seconds, the ESC mode light flashes in alternating colours (red/green I think, I'm colour blind heh). When the lights are doing that, using the throttle does not make the motor do anything. After a few seconds, the lights stop flashing and when holding the throttle it goes back to the same beeping/whining noise. Again, holding throttle on for a few seconds causes the mode lights to flash alternating colours again. I swapped out the motor for the 3.5T (which has run without issue for several weeks in the past) and it does the same thing.
Now, in an effort to get back racing I bought a new LRP Sphere Competition TC Spec ESC. The brand new 13.5T LRP x11 brushless didnt work in this new ESC so I'm assuming it was dead out of the box. I put in the 3.5T brushless which is known to work and voila, it works. However, it only ran for 1 weeks racing before this new ESC is doing exactly the same thing as the original ESC did (noise from motor, flashing mode lights etc).
What on earth is going on here?
I think its possible the capacitor on the TC Spec ESCs have blown - the end is raised slightly (definately not completely flat) but its not as bulging as I would expect from a blown capacitor. Whilst I never looked at the original capacitor, I did compare the new ESC and the old one and noticed that the new ESC's capacitor was flat on the end, but its now slightly raised.
What will the ESC do with a blown capacitor?
Will the ESC still work but not as good, or will it not work at all?
Has anyone experienced this before with the Sphere Comp TC Spec ESC?
All wiring/soldering has been checked and double checked. There are no shorts, broken circuits, dry solder joints or whatever. Some of the cabling has also been replaced in the process of swapping in/out motors and ESCs. THe servo still works and the transponder powers up fine.
I guess I should also mention that I am racing 1/10th onroad touring car on an indoor carpet track at www.PRECC.org.au
in Perth Western Australia (if anyone is in the area, this is a great club to join!).
Hundreds of dollars spent on LRP products and none of them are performing as I expected. There are so many positive reviews on both the LRP brushless motors and ESC but I'm starting to wonder if LRP products are really all that great (dont get me started on my issues with their AI Runner Plus Reverse ESC!).
I really would love to get to the bottom of this.
Does anyone have any ideas?
