I'm running a SPv3 17.5 with an FDR of about 6.4. Settings are as follows:
4/8
9/8
12/7
13/2
14/3
15/2
If I tried to gear up much more, it would get slower and hotter. Timing on the motor is maxed.
Track has about a 95' straight. You can see it
here. Layout is different now, but that gives you the gist of it.
Syndrome....here is the settings I just ran on a carpet track about the same size of the one in the video. My FDR with a 17.5 V3 motor on 10deg motor timing was 7.71 and my motor temp after 6 minutes was 160deg. It was just as fast as anything else there. We have noticed the same thing gearing up doesnt make it any faster just brings in more heat. For what we have seen gearing down helps more.
1--1
2--5
3--4
4--9
5--3
6--3
7--2
8--1

10-2
11-X

What you are saying is what we noticed right away. We had to lower the boost start RPM and then gear down to make more power. When we geared up with a lower start RPM the car would almost "two-speed" on the straight....there was a big delay until it kicked into the boost. Gearing down helped this right away and the car had more power across the board. This is what a hand full of us in my area have found while testing with the ESC and software.
