EKOS clone

[QUOTE=JPriami;217126]I ordered a Dragon Saga cat from the UK this week. I did a bunch of looking around to find the specs of everything and now I might be heading for trouble. because I was originally going to buy the new EKOS with the new outrunners. at that time I ordered new lipos for the boat and 36mm machine props by venom. But I ended up getting this other boat thats a clone of it because I liked the paint better because its not the EKOS paint job like everyone else has. So I want to know whats best or has been proven to work best to upgrade things like the motors in the EKOS boats.

Not really an EKOS clone. Identical hull and manufacturer. Difference is Venom is paying for licensing with King of Shaves. Love the look of that boat but I'm into replica boats. That one is a "one off" reproduction which u probably know. It is a model of the Segad C1 1995 offshore but says "Saga" on the side. Another cat with the same hull is the Jollymotor. Dragon makes this RC hull also. The real boat says Jollymotor on the side but the Dragon hull says "Mini Cat." link:

Great hulls though.

Ekos

I run a pair of these on the stock ESC's 3s/4s w/32mm props and get about 53mph out of it. The motors have 19 &25mm spaced mount holes and mount in the stock position.

Order a pair of Jeff's EKOS wire drives and Couplers. Best drive available IMO.

HTH- Good Luck!

Do you mean u ran those motors on 3s or 4s batteries? Whats the difference with those and the stock motors. Slightly lower KV (stock 2880 kv) and yours are 2700. How are you gaining >10mph?

4s, 32mm props. The motors are high rpm low torque, I unloaded them and let them spin up. There's a thread with my results as I was testing. The stock Venom motors didn't last long enough to test...

It eats bearings at high rpm though.

I had one of the stock plastic cooling jackets break Friday when I changed the cooling tubing out and run thing slightly different so the esc and motors have their own outlets.
So I just put the new 380 9xl motors and the aluminum jackets in Friday night. Along with the CF 40mm props and some loctite on the prop nut so I don't loose another prop. Tested Saturday without the gps. Ran good. But it was a bit windy. I caught some wind and the boat went airborne and did a flip in the air. But it managed to land and be rightened up thank you sea gods! Cause I wasn't wanting to go get a flipped boat. After that I brought her back in for the day. Went home and checked for damage. None luckly.
Today's gps test.
9xl's/11.1v lipo/40mm = 45.4 MPH
9xl's/14.8v lipo/40mm = 61.5 MPH


I have some video but it's not to great cause it's off my phone. I will try to clean it up some and post later when I get time.

Good day today :D

Did you try the programming card yet?

[JPriami]

It won't work on my esc's.

[LarrysDrifter]

Damn!That sucks.I guess send it back when you get a chance.

[JPriami]

Ok. You will have to pm address or txt it to me

[LarrysDrifter]

pm sent

Ok this video is not from my phone but from the small camera i use to mount onboard some of my rc craft. it has a clip on it and this time i clipped it to the nose peice on my glasses. what a great idea i had. but the down side is you can hear me breathing lol. guess i should hold my breath next time haha. but it worked for making a video and driving at the same time.

I moved it to the video page here.

Thats movin pretty good.How are the temps?

[JPriami]

The esc's are slightly warm to touch. The motors are cool on the cooling jackets and cool on the purple case. But they seem pretty hot on the center shaft. I don't know if that's normal being the only cooling is on the outside of the case. What say you?

[LarrysDrifter]

The finger method says if you cant hold your finger on the shaft for 5 seconds,its too hot.Its normal,but you could use higher amp esc's.That will help alot.
