| LCC, MMP, Novak 21.5 motor question
This question is more geared towards the Novak motor.. I did some searching but didn't really find the answer I wanted.. I'm running an LCC with the new worms, MMP, 3s, Novak Ballistic 21.5 crawler motor 14t pinion. I've be running Losi mtrs and made the switch this last week.. Got a chance to run it on the rocks this weekend and have some questions on the timing.. The other brushless mtrs I've had did not have any timing marks. The Novak comes set to 30 degrees.. I noticed with the LCC that it had more speed in reverse than forward.. I moved the timing to where the speed was about the same, or maybe a bit faster forward.. This brings the timing up close to 45 degrees. Running it this weekend the motor got hotter than I would like and seem to go through batteries quicker.. I'd like to get the timing closer to 0 for more torque (and probably less heat) but the wheel speed decreases quite a bit.. I can also use the cheat mode on the MMP, but I'm not sure it will bring back the needed wheelspeed without getting crazy on the advance. I'm contemplating swapping the tranny around, but that brings in another whole can of worms like mounting the dig servo and battery.. IF... I time the motor closer to 0 how much timing with cheat mode do I need to use (and be safe) and at what RPM range should I kick it in.. Thanks in advance... |

I set my cheat to 30* at 16000-18000 rpm and I run 4s. With your 3s I would say try starting at 12000-14000 and see what you think or you could go 4s. It's all personal preference with the cheat I've seen a big variety of settings. I also noticed the forward/reverse thing you mentioned I set my end points on my radio at 115 forward 150 reverse (thats on a dx3r).

Thanks all.. I did try to recalibrate the transmitter and ESC.. I set the timing back to 30 degrees.. I haven't done anything with the cheat mode yet as I blew out a CVD and I'm waiting for parts.. 4s is an option I suppose.. |
