hobbywing ezrun 150A vs Mamba monster

Wondering why that is....


Also he has ran the setup all weekend and still running awesome and cool with even more aggressive gearing. No dead ESC yet due to (cheap lipo's ) either.

The only thing I can think of is that even at full tilt, the MMM isn't sending the full PWM signal to the motors. It can't be voltage drop or there would be a ton of heat on the ESC. Don't know if this was mentioned, but you should reclaibrate your radio to the ESC each time is is swapped. It's possible that the MMM isn't seeing the full throttle it expects at WOT, so it's really running at 95% instead of 100%. When calibrating a radio, I set the EPA to 100%, calibrate the ESC/radio, then boost the EPA to ~110% to ensure the ESC gets to full throttle and is unaffected by some throttle potentiometer "drift".

jz, BrianG might be right on this one, but I've heard of people saying the Mamba Max was also faster then the Mamba Monster (Not sure if it was here or another forum) which is strange as they both share the same software. My only guess might be the different brainboard might be taking something away from the MMM.

How did the motor temps compare between the MMM and HW150 after the same running time? Seems like the HW150 should make the motor run hotter.

After about 10-15 mins of running hard on the street the MMM was around 100, the HW was around 115-120. Not a big difference, but when hooked to the HW ESC, the HW motor has a fan....so it NEVER gets hot with it. We ran the truck at the track Sat. after 15 laps (~15 mins) the motor was very cool with the twin fan setup from HW. I needless to say was impressed. My buddy bought the HW setup from me to replace his MMM 2200 combo. I still think for a true race setup though for long A-mains, I personally would run the MMM/Neu combo, but that is me. I like the setup...even if it gives up some mph. Nothing some re-gearing wouldn't solve.

[Aceldama]

Do you think the HW150 would be a good combo paired with the CC/Neu 2200? Or maybe a 70 or 80mm Medusa?

[jzemaxx]

Yeah...very much so. The HW 36-74 motor is awesome as well. I would love to test one against a Medusa.....I think they are probably very similar.

[mtsmat2008]

wat motor are you using the hobbywing 3674 or the 4465?

[jzemaxx]

The 3674.....its a beast!

[mtsmat2008]

the revo is prob 2 to 3 pounds than my lst2 is gonna be. not sure if i wanna risk it .i think ima go with the 2000kv 4465 motor but then again wats 150kv!

I had a thread on this 6 mos ago.I lost 4 mph in my E-revo going from a Quark 80b to a MM, Everything else the same.Gained 2 back when I went with the MMM. Something is going on ,I just wish someone would figure it out. I messed with settings , controllers and gpses and never could find the lost performance.Good thing the MMM could handle higher gearing .

[Aceldama]

The 2350KV rating on the HobbyWing motor seems kind of high if it's intended for 5s and 6s setups.
5s @ 3.7v = 42550 rpm
6s @ 3.7v = 51060 rpm

Isn't that a bit much?

I highly doubt the EZRun motors would equal the CC/Neu ones considering the EZRuns are 2-pole while the CC/Neu are 4-pole (and Neu's designs, albeit mfr'd by CC, which may contract that to China).
The ESCs look equal. For me, the price difference was justifiable enough for me to give the EZRuns a try. I already have their 60A EZRun ESC and it runs great and can take a beating (survived a shorted motor). The opening of the ESCs from other threads shows very good mfg and at least very good drive FETs. If they thought that much about the output drive circuit, I wouldn't think they'd cheap out on the other components.
But motor vs. motor, the CC/Neu is better IMO.

[jzemaxx]

I don't want to get into the debate of which motor is better, but we just ran on the track today, an endurance run to see if we would get the motor to thermal. The 3674 ran on the track for 1 hour exactly. Went through 2 sets of 4S batts in parallel and a little into the 3rd set. Motor never made it over 145 deg the entire hour after the 2nd and last pit for battery swap. That was around ~70 laps. Guess their motors are another valid motor people should now consider.....I am impressed. After running it, we GPS'd. 39.6mph on 62/22 gearing and 5.25" tall tires off the XTM XLB buggy.

Great review jzemaxx I have been following this thread waiting for somekind of confirmation that these HW motors/ESC are a good alternative.I bought sometime back a Bidproduct Motor and looking at the motor you would swear it was a quality motor.I tried this BP motor and after 20 minutes the motor just stopped.It was a 2600kv motor on 3s with a MMMv3.It ended up cracking the stator/magnet. Since then I stayed away from these types of motors.I found the Hobbywing motor seperately here for sale http://hobbiesbp.com
