undergeared or overgeared?

[InsaneRC]

OK i've had my E-Revo for a while now and taking a break from racing intil the fall season starts so i've been out bashing and my motor and lipos run hot idk know the temps yet (no temp gun yet)

my gearing is 15/68
my diff is stock everything is stock
running on x2 2s Lipos
MMMv3 v1.12 (Beta)

i've attached 2 pictures of my castlelink setup

please help me out i would like a gearing for bashing and racing

try normal timing and hmm....20-40% punch. Work with medium and low start power.


Also, for 4s setup, the 6v is WAY WAY WAY to low. try closer to 12-13

Raise your punch control to 50%, It'll be a little slower out of the hole but help temps. What size tires ?

[InsaneRC]

40 series Crimefighters
proline 40 series rims

Ok, adjust your punch control and test. Bottom line you NEED A TEMP GUN. For all we know your temps may seem hot to touch but could be perfectly acceptable ?

[InsaneRC]

ok adjusted motor seems hotter to touch i should be getting a temp gun @ the end of this week but batties are a little warm but not as hot as before

I wouldn't do much else till you know what the temps are.
What KV ?

lol my motor is listed in my sig Wander 10xl

You don't have to bust my chops, I'm trying to help. I'm just making sure that It's the motor we're talking about.

The XL motor is going to run warmer than say a NEU because it's not near as efficient as a better qaulity motor.
Put a heatsink on it and go w/it.

[InsaneRC]

heat sink is on it been going with it but just don't want it to get demagtized is all

Any reason you are using the older firmware? They newest version will have bug fixes, including some that may allow the motor to run more efficiently, therefore cooler.

I also have a question. In my erbe I'm geared 18/68 on 2x2s turnigy 5000(20c-30c). I think I'm undergeared, since the motor temp is 120-140f and the ESC fan comes on often. I then slow down and take the lid off and it stops. The case is always around 100f.

I don't want to gear higher, since my batteries aren't that strong. Using the calculator I'm at 31mph. Should I pump it up to 40mph? I don't do WOT for long, just for acceleration. I don't have castle link yet so I can only program through the tx. I'm at low timing, low start power, medium or low punch.

BTW, when I want to do wheelies, sometimes I can't. It looks like it has "turbo lag". I think that's the punch's fault and not the battery's? I'll try disabled punch and see how it goes.

well i found out my temps on my motor its running @ 140 degrees top on the motor itself the heat sink heat runs 105 degrees
