Littlescreamers 63mmwater jacketed Motor

[Xfactor]

So is it safe to say that at 10s the most this motor would want to see is approx. 216amps?@ 14s 154amps?Can the castle not handle the amperage?

Oh i know props very well . Im aware that a 1600 series prop has a 1.6 inch pitch and is made to generate lift. I also know a x460 is a 60 mm prop with 1.4 inch pitch. All you have to do is read to know that. Of course a higher pitched prop puts more load on a motor. Thats obvious . But I do not think that a 1667 cut to 62 is gonna put a 160+ continuous amp load on the motor/speed control. As far as props the octura prop chart shows you clearly what props are for what. An x series is really for monos. Yes we run them with much success but Ive personally seenn better running hydros with 16 series props. Dont take my mentioning of one particular prop to jump on board and tell me im wrong. Reguardless Im gonna try other props than an x460. I mean you wont do it so....Your 460 doesnt do much more than a 457 all it did was generate more amps. There wasnt that much of an increase in speed to talk about it. My personal opinion tells me that this motor @ 10s needs to see about 122 amps to run like what I consider a competitive scale.A 1657 is what im leaning towards.

burning up a shultz is easy all you got to do is have the timing wrong. Not only that I dont know how well built they are but if 40.160 means that that esc is capable of delivering 6400 watts continuous. Anything over that and you getting into no mans land I care less what brand it is. This stuff is physics, sure there are better product and worse ones but we use numbers to put everyone on a level playing field and so that we can share data that can mathmatically calculated. This gives you a theorhetical starting point. I never said you dont push it. I said how do you know what it will do if you dont push it. By the way what was the amp draw on the x460?

[Xfactor]

by using a datalogger. You can easily find the limits of your gear without having to toast it. As mark said, he would need a different esc to go to bigger props. He didnt say the motor was limited to that size prop.

neither did I actully Im saying its not the only prop so can we try something else
AB C anyway

I think the castle can handle the amps just fine. What it can't handle is spinning this motor. Whenever we put a bigger prop on the boat the motor just bogs like it cant handle turnning the prop. Everyone needs to wait untill someone trys a different controller to see what happens before jumping to all of these conclusions.

spotme2, did you see the videos of mine and Radtecs boats running with this motor?

Mark pm me some numbers why go through all this. The timing on that castle is obviously wrong and Like I told you before firmware updates do nothin if the harware isnt in place to support it. ill ask you again is that castle made up of p and n fets or stricly n fets if its the latter you need to be looking at the charge/discharge characteristics of your power supply caps. NOT the external ones people are adding I mean the ones that supply the floating power supply on pure nfet esc. I even told you guys that the dean of the engineering dept worked hand in hand with fairchild semiconductors and we would like to design a esc that can handle 50-60 volts and a continuous load of 200 or better based around your motor, but I needed some specs from you. I cant help you guys If you wont let me. thats why I bought one so i can test it get its numbers and go from there.The esc technology is relevant to the school because of the push for alternative fuels. Im trying to hook you guys up but hey u know the saying about a horse and water.

[Xfactor]

The improper timing makes opposing poles active at the same time inducing cogging. The can doesnt know which way to turn in this scenario. Thats why i told you we have a need for a closed loop system. That would help you deal with cavitation,smoothness,amp spikes ,etc.

I did not want to come out and say this but the CC esc do not want to play nice with our motor. In the testing done the CC esc is holding the motor back. After testing with Turnigy Monster 2000 the motor ran great and added at least another 10mph to the boat and all stayed cool. But this is a air esc and does not like setting up with a wheel radio. Steven has some new 240A esc's and I will be testing one soon. We worked with CC for many months and many new firmwares but they just could not get it right.

cuz they lied to you hello you guys just dont get it

[MarkF]

Ive tryed all the timming functions. The boat controllers dont share the airplane controllers software. Thats part of the problems. I dont have any data logging equipment to give you any numbers yet. I can tell you the lipos and controller are barley warm and the motor gets a little hot. I would love to see a 60volt controller for my boats and airplanes. I dont know how to tell what fets they use. If you put up a list of the questions you need answered then I'm sure the right people would see them and get your answerers for you.

they cant fix it with firmware alone im not gonna say it again. I deal with bs everyday. castle lied to you to keep selling u speed controls. What do you have to lose letting me take a shot at it? I got my own motor dont need any charity just two comrades working together to benefit us all. Wake up yall.

[Xfactor]

Mark you wont give me any numbers so vent

[Xfactor]

Ive been running them for over 20 thats not the point if you havent had time to test it say that but weve been on a 460 for two weeks now lets move on. 15 years should tell you just use another speed control and when you do try some other props.

[Xfactor]

Anyway the offer is there Im not gonna argue anymore about it . When you can give me some numbers and stop making everything a freakin mystery we'll talk again. Good day my friends.

[Xfactor]

Had to say this sorry.Why would I buy a castle if they dont work? Im trying to teach you but youre unwilling to learn.My modeling friends have many accolades as well who cares?We want to know what the screamer will really do. Scott if you need another beta tester hit me up.
