Hokay. So this weekend wasn't too bad. I got to run the buggy in another club main, and she did ok.
Correction to the diff fluid:
Center: 5K
Front: 3k
Rear: 1K
Spur: 46t Spider center diff
Ran the buggy on 3S (TP 40/80c 5000mAh), and she did alright. Also ran the T8 with out the sensor lead...seems to perform similar to a Neu. Didn't have too many problems with temps.
Motor: 142
ESC: 125
Batt: 105
Ran 2 10min mains. Not too bad, setup was still cogging a bit (a little more than the Neu). Power delivery is so-so. I ended up swapping out the R1-Pro for the RX8. The R1-Pro is a tough lil bugger for sure, but she's just not capable of handling the current draws of 4S. Either that, or my gearing was all out of whack.
But...overall, my observation still sticks from last weekend: I'll stick to Neu.
I also had a chance to run my X1-CRT in a couple of mains. I'm pleased to say that the RX8 didn't hiccup one bit on 4S and I was even doing well enough to place first in the three mains we ran. My mentor flamed out early, and I was able to hold my own against two Mugens and a X2-CRT.
The 4s (SMC 40C 5000mAh) is nuts...but interestingly enough, the temps were lower.
motor (Neu 1515/1.5D/F) : 125F (4s), 135 (3S)
ESC (RX8): 123 (4S), 126 (3S)
Batt: 4S: 105
3S: 120
SO...in closing, I am not too impressed with the T8 series. Perhaps I need to try a lower KV motor, but from what the 2650 has shown me, I am more incline to stick with the Neu. Although, to her credit, the T8 was an absolute monster on 4S in the buggy. First time I seen the buggy wheelie. Usually, with the Neu, I get nothing but wheelspin and paper plates. The T8 was a fraction less powerful than the Neu, which I think enabled the tires to hook up and loft the front end. Not too bad, but my vote is with Neu for now.
SO....anyone want to purchase a T8 2650kv motor from me?
I'll price it fairly. Open to trades as well.
