I do agree that most of the fade comes from voltage. It is hard to beat more area under the curve. This just goes to show what an efficient set-up combo this is. It is able to turn fast laps and remain consistent for the full 8 minutes. It doesn't mean that my other set-up was optimal, but that the Sonic was very quickly dialed in (within 3 runs) to a highly competitive level with a large sweet spot.
In this case all the comparisons are done from the same two packs, same layout, same set-up, tires etc a weekend apart.. Fast laps and top average lap differences are negligible compared to my "gold standard" which all of us here have massive amounts of time on and I consider well tweaked in.
A few other very experienced and seasoned racers looked at the numbers as well and all were surprised at the consistent pace from start to end. I had a strong car up front, and the strongest of the three at the end of the race.
I have some theories that center around the small rotor, but only more track time will tell. The motor definitely has a unique feel compared to what I'm used to. It revs up very quickly, and feels very "free" both on the track and on the bench. *Shrug* I feel like I'm wandering into a realm of esoterica and I'm a man of science dammit!
Or maybe Reedy just got the stator/rotor combo spot on for certain situations allowing better efficiency at all voltages? There are people allot more knowledgable than me on these subjects, and I would love to hear their ideas. Even if it is that I'm a quack.....
No, Andrew was running standard packs. Let's just say except for Orion packs there is "no replacement for displacement".....
I have included a little PDF of some recent 1c packs that went through the GFX as a "just for fun reference" (this means don't get all up in my business about sample size, etc although my procedure is sound and consistent). The Reedy packs can run with the best. The high voltage Rev pack was charged in "competition mode" on a Thunder Power charger which is why it is so much better. The Rev is a 60c 5600mah, the Murr 1c is a 5400mah 65c, the Reedy cmock is a 60c 5500mah, and the reedy 65c is a 6500mah. Pretty much mah = more voltage, or the term I use, less "voltage supression".... All done at 35 amps.
