Jim,

How old is the 603? It has a very short shelf life once opened.

Well I tryed this motor today in my Insane mono and I must say that I'm a little disappointed. I ran it on 10s 2p 10,000 mah Thunder power 25c cells and a Castle HV 240 controller. The controller worked great by the way on this motor. I thought this motor would be able to swing a gas size prop. It can't. I started with a 6517 prop and then went down to 6515 prop. It wouldn't get on step with these props. (These are some of my mono props when I run the 2230 motor.) The smallest I had was an abc prop that was 6014 in size. Simular to a Octura 560. It finally got on step and I would put the boat at high 40s maybe 50 mph. I did 4 laps with the 460 prop and when I checked the motor it was hot to the touch. I think Randy was more in the ball park with the 455 prop. Maybe a 457 or 460 would work. I had the 1/4 prop stub on my boat today so I couldn't try any smaller props. I will switch out the prop shafts and give this motor one more try. I also dont like that you can't support the rear end of the motor. I thought this motor would compare somewhere between my 2215 and 2230 motors. It doesn't. My 2215 2y motor has more grunt, can swing a bigger prop, is lighter and is faster due to the higher KV. I'm sure there's a little more there with this motor but its not going to compete with a gas motor in a big gas boat. I'll check back after I run this motor some more.

Are you running the 650kv motor Mark? Too hot to the touch doesnt sound good on that prop.

I assume its the 650 KV. Do they make other winds?

Their 800kv version is supposed to be out sometime soon. I was wondering if you might have received one of the first ones to test. Its been on my radar for a large mono build.

[sailr]

probably a year old. Bummer! I've made up a few shafts with it. Always tightly capped. Climate controlled environment.

Well I tryed the motor on some smaller props and the results weren't any better. I understand that the castle doesn't run this motor very good from what I have been told so I will hold off on testing untill I can get a different controller. Maybe there is still hope for this motor.

Yes I was gong to come in here and tell everyone that the Castle Creations ESC's do not play nice with our motor. I know from the testing done that the motor will run hot and not turn the props needed to get the speed. Using a Hobby King Turnigy monster 2000 it runs great and does not get hot. The dif was when using the cc we could not get better then about 55-58 and all was hot. using the other ESC we get 65+mph and nothing gets hot. It all in the esc.

I did not want to go out and say "Do not use this esc" but it is the truth.

Ummm, before I bought the motor I PM'd you about whether my CC 180 HV would be OK and you said it would be fine.......now we get a different story??????

I assumed I would not need a different controller to get the best performance out of your motor,,,,now the price I paid doesn't seem all that much of a deal.

[Littlescreamers]

We will figure this out!

I talked to the R&D dept and they sent me over this.

Please give this a try and let us know how it works,


Hi again
Well I went back to the oldest version I could (2.11) and set the motor timing at low and 8khz and it works. I don't know why but it works.the only thing unusual is it stutters at wot.Bring it back a notch on the throttle and this stops. Also on the other firmware the voltage dropped very quickly and it shut down. The temp of the ESC was 83 degrees C. Now the LVC doesn't happen at all and the temp is only 35 C.after a run. any ideas?
thanks again
Steve.

I have been told that if you can find version 1.54 it will run the motors the best we have ever seen. But it is not on there site anymore.

Our reply
Advance the timing one setting above low and problem solved with the stutter and no need to back TH off a little.

DO NOT USE OUTRUNNER MODE

We have only 6 magnets in our bell and this setting is for motors with more magnets and does not like our configuration.

[Brushless55]

I'm thinking its in the timing..
each motor runs better with different settings

[Littlescreamers]

This is our new project. 92" long and running a twin Littlescreamers Hurricane 63mm outrunner water jacketed motors.

More info to come.

From the R&D dept,
