I agree on the outrunner issue they have there place but not ideal in all situations.

I'm running a 5s A123, very close to 4s Lipo voltage. So the 15t/68t combo I have on it now should be in the good range:smile: I was thinking ~2000kv for 6s2p A123 would be good, not sure if I can get away with 8s1p, 8s2p is way too heavy, Need an HV MM ESC to go 10-12s A123. The more I think about it the more I think 8s1p should be ok, I could get away with 5s1p but I'm not sure 7-8min run times would be enough, 8s with the same power output would give 10-11min runs

We were also given a glimpse(verble) of the new Castle/Neu motor by Patrick so I might just wait for the MMM combos, Heavier, stiffer case, larger bearings, and more surface area then the true Neu 1515/1D motors. The only thing I dont care for is they are not going to wrap the rotor:whistle: I threw a magnet in my Aveox 1010/2y(unwrapped rotor) at under 30k. The wrapped 2726 rotor I installed has been fine running 40+k. Maybe adhesive tech. has improved enough in the last 10yrs.

Since we all like pics, here is the truck this setup is really for.

Spur is a 49t, largest pinion I have so far is 14t. Diffs are 13/38(2.923:1). Once I decide on a dedicated ESC/motor for the E-maxx I'll give the EMT it's MM back and try the Medusa and a Hacker C40-8L.

Here are some Pics of My sons EMT, it was built by Santa and the Elves:lol:(me and the credit card) For X-mas this year. Hacker C50-13L/MM, 2s A123, 9t/52t gears to keep the speed down. He got a JR R-1 TX for his B'day so it's on a PCM RX now and no glitching like the RTR TX/RX had.

that's cute. I have more fun watching my son drive my r/c's than I do driving them myself.

I thought I had turned the startup power up but I guess not, I did try increasing the timing to 15deg. No motor temp issues(105f after sitting a few minutes), but the ESC was peaking at 150f several minutes after a 10 min average bash session.

I just installed a small fan I harvested from an old laptop. Might need a larger fan though this one really doesn't seem to move much air. I hope just having constant air flow for the ESC will be enough.

I was running the 15/68t combo, I dont have a 16t pinion but I do have 65 and 62t spurs so I can hit a ratio either side of 16/68. If I can get the ESC temps down under 140f I will try some taller ratios, I'd like some more top end.

Is that MMM shipping yet:whip:

I sure wish it would stop raining!

Not much going on for bashing around here but I did get it clocked by a radar gun yesterday. I was cought doing 42mph through a rough yard.

Still running the 15/68t gears, motor temps are still around 100f, but the fan on the ESC does seem to have helped, I didn't drive long, probably <6min but the ESC never got above 90f. 6 min without a fan had the ESC up to 135f.

i think medusas are somewhat 'neu rip-offs'... the rotor is 4pole,segmented, and housed inside a carbon shell [instead of kevlar; i guess that saves some bucks,but it`s a lot better than nothing], and the stator is slotted [don`t recall if it`s 8 or 12 slots though -it`s been almost a month since i teared my 36-50-2200v2 apart to check the insides]. the construction seems solid, even though the motors are designed in usa but made in china i believe [that also helps keeping the costs down].

nonetheless, i think they are a good option for those average bashers out there, who [at most cases] are between a cheap feigao [or ammos and similar -disposable- motors] and an expensive neu [or lehner].
now what we want, is 70-75mm medusas for our heavy trucks :yes:

I have the v2 motor. Looking inside the can thru the front cooling holes it appears to have a 12 slot winding. It really looks similar to the inside shot of the neu and plett motors that I have seen.

How do you get the can apart? I guess that the rear endbell is pressed on? I tried to disassemble an aveox motor that I had bud did not have any success.

My Aveox are easy to disassemble. Most motors have that back glued on and sometimes it makes it easy to heat it up a bit to soften the glue. One ? though, why do you want to disassemble it?
