Hi guys. I have a new EKOS with the outrunners and they can only handle 3s. What motors are some of you guys using on the newer EKOS to replace the outrunners?

good post i would also like to know what motor to put in it, and also do i use the stock motor mounts or change them out?!
I actually tried them out and they seem to work fine. I was worried the length and weight would be a problem with the Feigao's but the mount seems to hold them fine. Bench revving them they didn't seem to move or vibrate. This is also a considerably easier mount to use. One vertical screw rather than trying to reach into the sponson and turn rear facing screws, which was unbelievable frustrating.
k cool, so u put the feigao's 540xl on the stock out runners mounts? did u have to get drifferent couplers to go to the motor shaft?
What's the diameter on the inside of the mounts? Or outside of the motor? I may be able to get some outrunners rated much higher.

this is what the specs say for the stock outrunners on venoms web site, but no info on the mounts
Specs
Length: 41mm
Diameter: 27.8mm
Weight: 80g
Battery: 2-5 Lipos
Max Current: 42A
Kv: 2700
No Load Current: 2.1A
hopefuly that helps, if u find some better outrunners or inrunners that will fit the stock mounts let me know ill buy some, right now i took my boat out with me to lake havasu, AZ and was running 4s lipos and it did great the stock ESC didnt even get hot!! but the outrunners were hot but were still running good, i just wanna find a better motor so i dont half to stress about blowing the stock ones up
Yeah, I understand. Don't worry too much about the outrunners temps. They can get hot and still be OK. Outrunners are much more durable than inrunners. The magnets spin around the coils, so less to worry about them flying apart from the epoxy failing like the inrunners did.
I need the actual size of the mount to help. Also the motor shaft size. There's a couple options, but not sure about those two dimensions.

You need to measure the motor bolt spacing, then you'll know what you can use. 380 motors have 19mm spacing, and 540's have 25mm spacing. The old EKOS mounts have a 19mm spacing. I run 540's with the old mounts. I run Arc motors with dual bolt pattern spacing. And these motors run awesome by the way. Here's a link to them.

They are a bit pricey, but you definitely get what you pay for. Only a Neu of the same size MIGHT out perform them. Bad part is, they don't make a 40mm can. If they did, some other manufacturers feathers would be ruffled.

Thanks for the feedback but the new mounts are around the can. They don't have bolt mounts for the end of the motors like Venoms old green motors. The Feigao's fit, and perform better than the outrunners that are stock on the newer EKOS. The 540 size is definitely out. Limited to 380's or replace the mounts.
Correct me if I'm wrong, but if you are able to install 380 motors in your mounts, Arc makes 380's in various kv's. They have a 2800kv that would scream and run cooler than any fegiao 2 pole. Very efficient motors. Use 120 amp speedos with x442's and you'll be sittin pretty.
Still need to know the inside measurement on the new style mounts. That'll tell us what motors will fit. =)
Larry's got the good setup info on these 32" twin cats, so as soon as we know what size motors will fit, Larry knows how a bunch of them perform and how to power them.

k so ill get my Mic out and see what size the inside of the clamp is and what size the shaft is

I don't understand the question. The batteries are 4000mAh 40-50c 4s. I also use four 2s, 5000mAh, 50c packs. Two wired in series per side for 4s.
