MGM Programing Questions
 

I have mgm 160/18 controller and I am not getting any beeps etc when trying to program the transmitter for throttle brake limits I wait 10sec nothing to let me know its in programming mode, it works fine using my pc, but arent you supposed to set transmitter limits first before anything? It does work I had adjust some throttle trim cause it was slowly creaping forward..also it has a dead spot in throttle before it moves forward, is this from transmitter limits not being set? Oh and I am doing all this with motor 1515/1y "disconnected" for safety ...do I have to have motor connected when doing this? Can I use just pc to set throttle brake limits? using a DX3.0 as transmitter...help ...thanks

The motor windings are what produces the "beep" noise. So with no motor attached you won't hear a thing. For the dead spot, reduce the "neutral range" parameter, that will tighten up the response.

Yes, the motor works as a 'speaker'

lol I feel stupid now ...thanks guys

No need for that, just blame the freaking refrigerator magnets..

What PC setting should I set it at I ran it (1515/1y) 4s lipo and it seems to be dragging on or off throttle...everthing was cool though says max peak current was 191.36 amps and rpms 4988.4 ? What setting should I use for: acceleration and timing ?

Sounds like you need to set the freewheel option to the on setting

Dont ask me why, but the default setting is off.

yep it was.... I turned it off....didn't get chance to run it again...I hope its alot better seemed not as fast as I would have expected maybe 4s isn't enough ....what happens when you change the acceleration settings does it give it more batt power?

try the .39 accel setting

Knotted made a good point...connect the motor and you should hear the "beeps." If you are concerned about safety...remove your motor pinion (or at least back out the pinion grub screw).

Ok so its motor power=acceleration settings with different levels say .39(powerquicker)vs .62(power comes on slower) ? What about the auto find neutral setting should I have on or off?

With the defaut settings on mgm160 controller with neu 1515/1y 4s maxamps lipo in 3905 maxx with 68/20 gearing it didn't impress me, ... it was decent, I want stampede vxl performance in my 3905 if that makes sense...I have not had a chance to run since changing the freewheel setting to "off" and putting the accelerating setting to .013...its raining and 32 degrees today dang it....hope the freewheel setting will help make it seem alot faster...otherwise should I go 5s or 6s on this setup?

Give those settings a try. If that not enough, go to 5s, 6s may be a bit much for that motor.

6S might be hot, but castle would launch their MMM 6S capable with a neu 1Y clone. (so i've heard..)

It's pushing it too far in my opinion.

68/20 is 17.7:1 final drive ratio, which only geared for low 30's with the 2200kv 1y on 4s. For bashing you can easily go to around 14:1, or even lower for high speed bashing.
I don't know what size spurs you can get for the new e-maxx, but 24 or 25t tooth pinions is what I'd use with the 68t spur for normal driving or racing. After that if your happy with the temps and still want a bit more speed you can still gear up a little bit.

I have a 24t pinion thats as big as I could find ...I will try and see how that does ...with the 20/68 everthing was cool after running.

I have a 58t spur the 24t pinion might reach ..lol ....Its 28 degrees and icy here this morn to I will have to wait for bit......I may go to 5s right now I am using (2) 8000mah 7.4 maxamp lipos in series.....maybe use two 5s 5000 18.5v packs....I already have two 3s 5000 11.1v packs I could run in series...6s too much you think for 1515/1y?

Only gear up if you staying with 4s. If you use higher voltage don't gear up until you see how it goes.
For normal use I would guess that 6s is a bit much on the 1y, but I'm not sure.
I'd just try 68/24 on 4s first and then go from there.

I put in 62/24 and the 58 jato spur fit fine, I just couldn't get the big ribbed new close enough without hitting the tranny even with 24t pinion .......test tomorrow

What about with the 68t spur.

Ok I ran the 62/24 on 4s with mgm settings changed (freewheel off, accel .013 setting) and it ran much better faster, flipping on its lid now... motor and esc were barely warm ... it was ever so slightly spongy down low so I think I will try 65/22 gearing....I could see 5s being perfect for me but I want this to be driven by friends when they come over so 4s is plenty for this ...I want to run 5s in my revo setup, but will try the 4s first
