the new epics are suffering like the fukayama mako. those knuckle heads are drill balancing so deep that when the armature revs higher the segments are flying arpart due to centrical force. i still prerfere the epics, just buy ones that aren.t balanced. in my experience with these motors, the pro ones don't perform as well as the oem non pro motors. on the non pro with red springs and 4499 brushes it revved 3000 more rpms. the armatures are smaller than the monsters which is why they rev higher.

in any case gear down one or two than what you would gear your monster. and yes whatever you're geared at, these suckers get hot. their ability to rev is due to their smaller stack of segments. go a head and compare. the monster is bigger. a binary arm is in between the epic and monsters.

i know a bunch of you are thinking, a balance arm is better than one that isn't. true but if the holes are to deep you'll result in a blown segment like kilruf. until epics fixes the problem think of it like this: more material more torque, and less worries about blown motors.

Default Epic Stock Balancing

Guys;

Actually the Non-Pro Motors are balanced also, so I'm not sure balancing wise if there is any difference between the two.

Either way with as few laminations as these motors have, I find they make more power with the least amount of drilling into the stack as possible.
Motors like the P2K2 that have more metal in the stack, don't seem to be effected as much by the drilling.

That is it. Thats what i am looking for for a 27 turn motor. I guess i could attempt to re wind it. I am going to try and find a 27 turn i dont like my luck becausre they dont run 27t in Asia.

Thanks heaps for the pick was a little blurry but who cares.

The problem with the Fukuyama balancing is taken care of....No more problems. I do think that they were replacing the ones that this happend to out of the first batch as well.

no but if they are any thing like the core stock, i'll be torquey i bet. not sure on the rpms but those things generaly run hot any way. i think the monsters, epics(2 or 4 mag),and p2ks are the top runners.

Here is my Binary... has 36 laminations. Maybe I got a fluke with the Epic Roar Stock. I beleive I got it a couple months ago. It's not the Pro version either. Maybe I'll just have to buy another Roar Stock and count the lams....

Do the big jim narrowed brush trick. That will lower operating temps and increase torque at the expense of rpm. The magnets are much better than all of epic's stock motors, so they will handle heat alot better.

Guys on Reedy MVPs,Orion Core's and Peak Hellfire's it's all about the BIG JIM brush trick which is taking a small amount off each side of the brush narrowing it.
Use reedy 767 or in alot of racing I run a 767 on the + and then a 766 on the - and drill a hole in the middle of the 766.
My cores work awesome in offroad and small to medium sized sedan tracks.I like the following motor's due to the magnet's being 10x's better and not wearing out.
