ok i'm reserving my opinion on whether or not my issues are gone, but i've had some success with the 2nd ESC and the 3.5T motor....
here is what has been done..
- sensor wire has bee changed and routed different to the ESC (it looks like the way i had it cable tied was pulling it out ever so slightly from the motor)
- sensor wire has been reinforce at the plug ends to ensure that impacts and vibrations arent going to wiggle it or knock it out
- ESC capacitor has been changed from the standard cap that comes on the TC Spec, to one which is rate 16V 4700uF and a peak temp of 105 C
- the ESC cap has been mounted in a different location, allowing better air flow around it, the motor and the ESC
- a second 4700uF 16V cap has had a lead attached and is now plugged into the battery port of the receiver.
- and whilst its not related to the issue, i've changed my gearing to a higer ratio and hopefully this will help reduce some of the current draw from the motor (recently had a battery explode due to heat!) and hopefully take advantage of the 5 cell setup and our track.
my initial observation from bench tests are that the voltage drop across the entire circuit has definately been reduced, noticeably when hitting the throttle hard. i've also seem to found a few more rpms and the motor really does seem to want to wind up fast - to me its in the realms of what the 3.5T sounded like with full charged 6 cell pack, only its now 5 cells
i need to see how this holds up to racing on the track before I draw any conclusions, but it also seems like the whole system is running cooler too (but cant really say this from the few blats i have done in the kitchen hehe).
i'm actually excited about race night tmw
