Quick question,
I realize this has probably been answered, I have read through countless posts and searched all over the web. But still, this question isn't totally answered for me. Figured some of you may know?

I have been racing my M05 in the Mini class, -we follow the TCS rules. Motors have to be stock silvercan, no funny business in terms of adjusting the timing, etc.

I am consistently getting about 3-5 place out of about 15 competitors. Which is good, but just can't seem to get into the 1st or 2nd spot. I have done endless tweaks to my car, -in the corners I am just as fast as the tops spots, yet I am dying on the long straights. In fact I would say that more than 1/2 of the field beats me on the straights (I make up the diff' in the corners and overall I think I drive a tighter line than most guys and thus run faster lap times). But the straights my car is dog slow. It is noticeably slower on the straights. I do not believe this has anything do w/ skill/driving ability -as mentioned I pull out ahead in the twists ...which I attribute to superior driving skills

I have raced for years, but am fairly new to the MINI class, -this is my first season and we are nearing the end.

Are some silvercan motors dud's? -i mean are they slower than others? It appears to me that there is about 30% in the field who have fast motors, 60% who have average motors and about 10% myself included who's motors seem slower. -ie, on the straights I am just getting passed. I have no power on the straights.

I am running a 45c Trakpower lipo,
Traxxas ESC (pulled from a slash, -brand new when I began using it)
Motor is the stock silvercan that came w/ my Mini kit.
I do have another silvercan from another application from years ago, the wires and housing are the same, yet the end cap is a different color (than the one that came in my kit). I have read that there are many different "silvercan" motors out there. Some say certain ones are more desirable. I don't want to cheat, so not really sure if I should be looking for some coveted silvercan ...unless that is what everyone is doing? Yet also which silvercan is the best is a bit murky to me.

I suspect that my speed has to do either w/ the battery, esc or motor. I suspect motor? Am I wrong.

Is most of the field cheating and doing something to their motors that I am unaware of? Is there some trick? ...I actually think that the Mini class in some ways is the most uneven, I run 17.5 on road and that really comes down to driver skill as all cars seem pretty equal (but I digress).
