Just installed a Dynamite fuze Brushless ESC and an Orion stock brushless 17.5T motor. The motor is used but the ESC is new.
Problem I have is that at full throttle the motor cuts out. If you pull back slow you can get to full throttle but if you pull back to fast the motor cuts out until you return the trigger back to neutral. This happens in reverse also. I went through the ESC programming several times trying different settings and still had the same problem.
This is our first brushless motor so think newbie when you respond...Thanks

My first guess is that your battery cannot supply enough power; what do you use?

Thanks for the reply!
It's not the battery. 2s 4000 LIPO's

I have 2 almost identical setups. After doing some part swappin' today (between honeydo's...) I have come to the conclusion that it is either the steering servo or the receiver that's causing the issue. Looks like I'll be rebuilding a spare servo that has stripped gears tomorrow.

Is it common to have conflicts like this...

Sounds like you're actually getting reciever brownouts. A power cap for the reciever will usually fix that.

It's the (Cheap FlySky) receiver. Looks like I'll be buying a Glitch Buster...

Thanks for Help!

I have that speed control. I notice it cutting out. I have diagnosed it to cut out during super high traction high throttle inputs. Like when my track has a bluegroove on corner exit and carpet. I think the speed control just literally cant handle momentary high amp draws.

This is in a TLR 22t with airtronics recevier and ko servo using 4000mah 20c and 5300mah 90c batteries.

I agree 100%.
It's happening now on the other set-up also. That one uses a Spectrum receiver.
Looks like I need capacitors for both systems.
Now for the next issue...where to plug them in. Since I have transponders on both systems I don't have an "open channel"... Did some more research and found a Servo Y-Harness. So the plan is to plug that into the throttle channel then plug the ESC into one side and the capacitor into the other. From what I have been able to read that will solve the issue.

Question...does anyone know if I can plug the capacitor into the fan circuit that comes with the ESC?

Found another Spectrum receiver in the tool box that has more channels. Plugged a Novak glitch buster into the spare channel. Took it out for a test run...no change! The motor still cut's out in high traction situations.

Now what???
Grandson is not happy and we have a club race this weekend...if the track is dry enough...

the only way i know to fix it is to get a better speedo. hate to say it like that but, i have done everything youve mentioned and nothing has fixed it. i think the speedo is overrated in terms of the instant amp draw and just cant handle that instant amp draw that full throttle on high traction demands.

the only thing i can think to try is putting a negative expo on the radio just to try and slow down the input to full throttle.

Problem solved...got 2 Brushless hobbies 120A ESC's today!

I just put in a fuze that I got from a buddy and everything works but when I go to punch it the throttle just cuts out what could be causing it
