>The other way is to push the truck and then accelerate away
The schulze 32.170 coupled with 11s1p A123 and a 4 pole Neu 1515/2Y (1100kv) was not able to start up the motor properly in a 5.2Kg 1:8 truggy especially in car mode. Heavy cogging from a stand still although the ESC is well overdimensioned in a 1:8 car. Schulze put the A123 cells at fault. We tried it with lesser A123 cell and nimh cells which helped somewhat but we were never able to start the motor up without cogging - we never expected such a behavior from such a high priced ESC. From a stand still pushing the car slightly helped the ESC to overcome cogging and as long as the car was moving the ESC worked flawlessly. An MGM 12545 starts the same setup from a stand still with absolutely no cogging. A small Jazz 55-10-32 ESC has no problem at all with a similar setup.
As you say it does work properly with your bolido motor, one might guess that the ESC has an easyer job to start up a higher pole motor as it will get better/faster a back EMF from the motor when compared to a 2 pole motor. Be prepared that when contacting Schulze everything else is to blame but the ESC.
14A @ no load seems a bit too hefty -> translates to 546 Watt (39V). Which kv version do you use? I have no experience with those big motors but my Neu 1515/2Y (1100kv, 340gr) uses no more than 2A @ 33V.
I looked through the
motor data which is hosted on lehners website. Even a 3080/6 is "only" @ 11A (40V) with no load and i think you chose a less hotter wind for your 1:5 car. A 3080/12 is @ 6A (40V) with no load. You may want to contact Lehner on this subject and you may want to try posting in boat forums where you will more often encounter those big Lehner motors.
One thing you might want to try is to start up your setup with lesser voltage (less cells). Maybe this helps somewhat. But in the end it will not be a satisfactory solution (if it works at all) since you will loose top end speed.
