New guy asks - Anyone ever setup throttle fixed endpoints on CC ICE75 & DX6i?
 
The new guy needs help. I have a question about setting up fixed endpoints on throttle with a DX6i and an ICE75. I'm going where I've never gone before so if anyone can validate, or even come close to validating my numbers, I sure would appreciate it.

I've been using automatic throttle calibration which on an ICE75 means every time I power up it learns zero first and then 100%. But it feels odd. The throttle response at zero feels normal but the upper end...well I'd swear that last 1/3 of throttle stick movement did nothing.

So after reading I decided to try fixed endpoints. I logged on to the ICE and changed the setting and downloaded.

Then I diconnected the battery. Then in my radio, under travel setting I noted that 100% was displayed for both 0 and 100% stick positions. I changed both to zero.

Then I set the stick at 100% and connected the battery. I kept increasing the 100% stick position travel setting one click at a time until the ICE75 played a tune and red light went from blinking red real fast to blinking red slowly. I then increased the travel adjustment value another 2 clicks and ended up at 67%.

Then I moved the stick to the 0 speed position and began increasing the zero speed travel adjustment one click at a time until the ICE again played a tune and armed. I increased the travel adjustment value an additional 2 clicks and ended up at 44%.

While I have a watt meter I don't have any sort of a tach. I have no idea if I'm actually getting 100% out of the motor. I did run it up to 100% stick position and tried increasing the travel position value from 67% on up and tried to listen for any speed increase but it didn't change a thing that these old ears could hear. So I put it back at 67% and left it.

I have no experience with what would be typical values, I got nothin.

So here is my question, does a zero postion throttle travel limit value of 44% and a full throttle travel limit value of 67% seem even close? Does anyone have a similar setup that can help me check gravity?

I guess what is sort of troubling is 100% was the default values when I had the ICE set for auto calibrate and while throttle response seemed odd...well I would have never guessed values of 44% for zero and 67% for high would be where I ended up once I changed to fixed endpoint on the ICE

Thanks in advance to any and all who read and care to offer any feedback.

The low number is correct because you were able to arm your ESC. Castle Creations requires a 0 throttle position to arm. When at 100 percent throttle the red light on the ESC should come on. If that is the case then you are setup correctly.

Your description sounds correct.

And your problem may not be in the tx or ICE.

If the motor isn't going any faster past a certain point, it could be your pack is not up to the job. Using your meter, watch it while advancing the throttle. If it gets to the point where the motor isn't increasing, be willing to bet your pack readings are maxed, and any more throttle will show a steady or dropping reading.

The motor wants more to do more, and if the pack isn't able to deliver the power, it will only go to a certain point before demand exceeds supply.
