jhautz, I read that too and it concerned me. I mean, how can an electric motor run better in one direction than the other? From what I gathered though, this difference is a result of the way that timing affects the Wye wound motors. If you have the timing set at an optimal setting for one direction, it'll be screwed in the other. Of course I could be way off base.
There are two perspectives from which I look at this. The first is that the Quark employs automatic timing which is supposed to set the timing at the optimal level by itself, in which case the negative effects of the timing in one direction or the other are moot.
The other perspective is that I'm screwed because the way that my Quark works with the Neu is that the Quark is showing the reverse light when I'm moving forward and the forward light when I'm in reverse. Perhaps my motor is spinning the wrong way.
The funny thing is that if this was an issue, why didn't Neu bring this up when I complained about the performance of the motor? I told them that I was running it in a truggy with a Quark.
Anyway, I ran the truggy for a while with the 1512 1.5Y. I had it geared 17/46 and the performance is acceptable for the track. The power is NOTHING near a Feigao 9XL geared 16/46. I mean this in terms of raw, brute power. With the Feigao, I had to be careful not to wheelie. With the Neu, I have to try to wheelie to get the front end off of the ground.
After 5 minutes of hard running, I got a temp of 115 on the esc and 160 on the motor. I would have thought that 17/46 would have been some pretty tall gearing, but the readings say that I need to gear up more. Maybe I'll try 16/44 later on and see what happens.
Oh, btw, the issue brought up by jhautz was the reason that I requested the 2.5d. Unfortunately, I didn't get it, so I can't tell.
S. Neu did email me back and say that the offer still stands, but the last thing I want to do right now is do any more waiting.
It really doesn't matter at this point. I still have that disgusted feeling in the pitt of my stomach and I think I hear ebay beckoning me for my 8ight T.
I do have to say that the Neu/Quark combo runs well. One of these days I might get a 1515/1Y for one of my trucks, just for the performance fix.
