Yes it shld handle better heat but also draw more amps

Seems like the difference between a L can and XL can feigao... Similar KV and the longer can will draw a bit more, but run cooler and thus more efficiently. So the amp draw ends up about the same... But the longer motor can run longer and will put out a bit more power.

80mm medusa is a good motor for a truggy or MT. Had a chance to use one on my friend's RC8t. Wheel stands any time and runs pretty cool. Way overkill in a buggy though. Was desperate one race day cause my 36/60/1600 was back at medusa for a new rotor + bearings due to bearing failure so I borrowed the 80mm medusa and raced with it in my buggy. Yep Overkill, but I was surprised that it spooled up rather smoothly even tho it had considerably more static resistance to turning the rotor by hand. This threw me off slightly over the jumps as it had more motor braking effect than my 60mm medusa and as such I nose dived a few jumps till I got used to it. Might borrow it again and get a massive pinion for a speed run just for laughs. I calculated 134km/h on 6s with a 36/80/1900 and a 25t pinion on my buggy. That's 10t higher than I normally run. I have the pinion already, gotta check if my motor mount has enough movement to fit it on. LOL.

Overall medusa motors are good for the money but keep an eye on the bearings cause they're small. Front bearing collapsed on mine after less than 6hrs usage. I will strip it down and check/clean bearings every 1-2 hrs from now on.

I run the 2350 kv model in my emaxx with a HW150A. The first one i blew up in 5 minutes of runtime, probably a mounting mistake. I may have used mounting screws that were too long and that bent the inner wire wich in their turn shorted with the magnet. Or just a production failure :)

Anyway I got a new motor from HW (GREAT service) en used shorter mounting screws. I had three runs up to now. One to test if everything works and two runs at full power. Constant high speedruns/full throttle in a park on long grass. I use a 21/62 gearing and 2X 2s2p 5100maH 25C lipo packs. The runtime was 13 minutes. the motor didn't get warmer then 51 degrees centigrade. This is with a heatsink and fan. The lipo got handwarm as did the ESC.
I think it's a great motor for bashing and it's a cheap setup. For racing I will use a medusa

Actually the bigger can simply means tat it has a higher heat capacity for the same load. It doesn't necessary mean that the larger can has lower intrinsic efficiency.

Then again with a higher heat capacity, the motor runs cooler on the same load. And since the motor runs cooler, the effective efficiency is increased as compared to the smaller motor.

The larger can motor should be running at almost the same current than the smaller motor if both have the same kv and the vehicle they are run in is geared for the same speed.

quick question about the 150a esc....

does it come with the motor wires and battery wires already connected? i ordered mine from nitrorcx.com for $99. the picture on their website shows it with no wires coming out of it.


They say a good mechanic only needs 2 tools - WD40 & Duct tape. If it moves, and its not supposed to, duct tape. If it doesn't move, and its supposed to, WD40.

I ordered the 150a ESC + 4465 motor from Swanghobby.

Motor and ESC was connected and there was battery cables on the ESC as well. I would have liked bullet connectors between motor and ESC... having the two wired up constantly is a bit unhandy.

Got to drive my xray xb8 conversion for 2 days when my HW80A died yesterday. up till then i was very pleased with it. program card is handy and it stayes cool. then all of a sudden after 5 mins runtime the car stopped and smoke came out of it. bec still works though. timing was 7.5 deg, punch was set to 5. ran it with a medusa 3660-2000 on 4s lipo. it took me months to finish this car and now back to the shelf again.

just wanted to ask for an update on HW´s customer service. i just wrote to the email adress that superek posted before. how´s your experiences with the cs lately?

Thanks superek,
i picked up jack`s address and wrote to him over a month ago.
He asked me to send pics of the esc which i did and never got a reply. I got a mmm as a replacement but i have to say that the ezruns are far better built mechanically. Maybe he reads this and contacts me again.

Hello, Sebsta

I just got the automatic message from the RC-Monster forum so I log in and check the thread and find your post.

You sent a mail to me? I am afraid I didn't get it. Please send it to me again. zj@hobbywing.com

Thanks!
