I hope Seaball will come on this thread, as he did not run 21.5 until Sunday (borrowed a motor). I think he could shed some light here.
first, congrats to haynes for putting it down on all of us. he didn't do it on rip alone, so let's get that straight. nobody drove like haynes did this weekend, and it didn't appear that anyone's car would corner like his either. that should not be a surprise to anyone, considering his vegas performance of two months ago.
i've driven t/a on two occassions, both with borrowed gear (car, radio, and power). on both occassions, i feel like the few cars that stood out in terms of power were using the 21.5/lipo combo. you can't really use lap times, because the sample size is just too small. even at our 240 entry halloween race (with 30 some t/a cars) there weren't a ton of drivers that could get the cars around the track very tightly. i drove like a total idiot, and still found myself inside of cars way too often for an 'a' heat/main.
getting back to the power thing, i'd have to rank the current options as follows:
21.5-L > Brushed-4 > 17.5-4
the 21.5 just makes more power. it jolts out of the turns and seemes that the 4.2 ratio is as wide as you'd need to go on most tracks (so it's not really a limit at all - as haynes implied).
the brushed motors were first proven faster than the 17.5's in the spring when they were both an option at the carpet nats. at that time, we tested some in a very controlled manner and the brushed motors (that we had) were simply faster in top end and showed a heavy .2/lap advantage (on a normal, 12 second layout). perhaps they have evened up by now, but i still have my doubts..
the 17.5's seem a little weak to me. with the tall ratios, they suffer on the low end, and as a brushless motor, seem to lack any real rpm to pull the length of the straights. there are exceptions, but this is what i've arrived at in the two t/a races i've run.
for me this weekend, my 17.5-4 combo was junk. however, my sticks were (i don't know) how many months old, and the 17.5 was said to be 'getting weak' by it's owner. so yes, when i switched to a 21.5/core-5K the car was ridiculous amounts faster, and i would agree with haynes that i probably shouldn't even have been at the 4.21 that we used.
like robk said... in the end, haynes was the only guy who 'showed up' this past weekend. good job michael!
