You should've seen my Recoil with the Mega ACn16/15/1 (9200Kv), it was out of this world. I have the Neu 1107/1.5D, but I made a mistake on my ESC and it burned one phase.

a 8500kv motor that pulls a lot of amps...now theres a surprise...:sarcastic:

I'm with azjc on this one.. I started out running a C4 9000kv motor that just seemed like small portable heater. Lutac, I'm sure your Mega ACn16/15/1 made a fair amount of heat no matter how efficient is. How long were you able to run it before it got too hot? I just bought a Neu 1115 1D (5700kv) that I'm going to try to stuff in another 1/16 project with a custom chasis. The thought is to run it on 3s and gear fairly high due to the expected torque output of such a long can motor. I will post some feedback here.

The Mega didn't get hot at all and most of the time I ran on the track. I was using a 16T pinion with the 56T spur. Too fast for the little track at Xtreme RC Addicts. I now have a 6 pole low Kv motor which is the only motor that the Kontronik Beat 70 Car actually works and I have a nice 22T pinion to get some speed out of the Recoil and one guy at the track could not believe how smooth my Recoil is. That guy btw runs the C4 9000Kv+ motor in his Recoil and it heats up pretty good. I have to see if Artur can fix my 60A controller which was the only one actually turning the Mega ACn16/15/1. Not even the Beat 70 can make it turn. I made a mistake on the timing of the 60A controller and it burned a couple of FETs.

I'm running a 25T pinion from a MLST in my "Recoil". I use quotes because it's actually a Carisma Nissan Skyline R32 which is essentially the exact same car minus the body and wheels, which I favor over the Sportwerks offering. I currently have a Hyperion Y-22 6000kv short can motor in there. It is very quick and top speed is pretty good as well. If I were to go to a track, I'd probably use this setup as it is. It does get a little hot after a few minutes, but I think adding a fan over the motor and ESC should tame things long enough to enjoy for a real race.

I have tried the Hyperion Yc-22 motors in my RC18 on 3s and I prefer the 5000, the long can will fit and IMO able to be geared up for speed without too much heat

I'm using the YC22-5000 in my MLST with stock gearing and 3S with no heat issue as well. Great little motor.

did you use the long or short can

Short can. So it is the YCS22-5000. It's a strong motor. I had the YS22-3000 (might be 3600, I blanked out). One other thing, I think the Hyperion inrunners are 4 pole motors and some places states as 2 pole, but if you look inside the ones that have the openings, you can see it's a slotted design and it cogs just like my Aveox 27 and my small Razor motor.

My next motor will hopefully be the Medusa MR-028-032-4200V2 to run on 4s. I'm not a guy who only runs extremely high kv motors on 2s. It's good for bashing and maybe a long race so I can run 2s 2p, but that's not all I do.
