Electrical Issues again!

[Badmofreaker]

I finally get it faster and now it doesn't work after only 4 passes in the 120's. It moves about a foot or two then shuts off like its going into fail safe or something. I checked all connections and even re soldered one,no difference. I tried 3 different batteries and no change. Is it possible the dx5 receiver can't handle,or did I try my castle xlx. Any input would be helpful, thanks.

Doubt that its the Rx.
4 passes in the 120's.... have you been monitoring temps between passes?? At those speeds (great BTW), temps may have fried the XLX... IDK.
What were your temps between each pass?? Are you/can you retrieve log data from ESC right now?

I got to 200 only one time, I need to back off on the timing a little

The max voltage went to 28.6 volts,that's a new battery

How close together were these 120mph passes? If they were back to back, my guess is you melted the motor. ??‍

 

[SrC]

Hitting these numbers requires zero timing IMO. No T. advance.
I think most of the hard core speed guys leave T. at zero.

I hope not

Yeah, I need to turn it down, its at 15

Log data may paint a picture for you if its retrievable.
Can you bench test the motor?

Depends on the motor winding.

What motor and winding are you running?

Temps weren’t too bad but your RPMs are 68k.... what motor is this?

Tp 2250

 

[SrC]

Not that timing cannot be used... but its very easy to overshoot your timing. Then the motor gets the brunt of the hit.

Where should it be 5,10, for those speeds

What winding?

4070

Ripple was good. BEC/5.5v was dead on good.(Rx is ok)

186F temp wasn't too bad considering. Your RPMs were over the top perhaps and related to timing? IMO.
Look over the motor well. Reset the ESC to defaults.? I always leave my Timing at zero until I know I have everything running perfect. All my data is perfect and always consistent. Only then will I advance timing conservatively. That's just me.

K,I will try it,if that don't work, I will switch reciever

Do you not know what winding you purchased? D or Y?

 

[Badmofreaker]

No

I know it's a to 4070,2250

 

[jondilly1974]

No

If you advanced the timing to 15 on a D wind, you likely fried the motor. Sorry. ?
