hello Patrick,
I install 1.39 and went on test drive...
the cutoff act strange...batteries were 3.8V per cell (4S) and the cutoff already start to slow the car...
so I programmed the ESC again and turnd off Lipo cutoff.
then I had more power but still have those problems from 1.38:

1. The car lost power, and Punch ... acting very strange and took a long time to accelerate. The car did not have Punch power.
2. stuttered The vehicle .. like the Cut Off is approaching (batteries were charged).... didn't happened becose I turnd off the cutoff
3. Random vehicle brakes every 30 seconds or so -now only break when I drive in high speed and then pot the trigger back to neutral, and when the car is still moving press the trigger again...the sometimes the car put itself into break...and the I cant controlled it for 3 seconds.. like lost signal..
4. The motor started making strange noises and sounds like it opposes itself...only make those strange noises when the car is acting like in 3 (when it break)
5. The ESC stopped to get a response from the remote for a few seconds every minute or so ... (after 2-4 seconds I managed to control it again)



can you help to get a stable version on my esc ? not a beta ...

I really appreciate your help !

Sorry man,

It sounds like there is an problem with that controller -- we tried 1.38 and 1.39 here, and had no issues.

If you send me your info, I can have tech support send you a replacment controller on Monday.

Thanks!

Patrick

I send you privet message...but I'm not sure if it was sent... it shows :"Sent Items contains 0 messages."

did you get it ?

Yep -- and responded. Unfortunately, there's nothing I will be able to do today -- but should be able to get you squared on Monday.

Thanx!

Patrick

This is what I call customer support!

Sorry you had a bad experience initially but looks like you are all set now.

Thanks Patrick and Thomas for stopping in.

New firmware on site...

Richard put up a version of 1.39 up late this afternoon that allows a rollback to 1.24

Thanx!

Some of the issues sounds like a badly calibrated radio system. Make sure you recalibrate the throttle range on the ESC.

That is awesome! Thanks guys!

THIS!!!

Monster, make sure you go thru the throttle recalibration after you do the update, every time. You may have to slightly alter the deadband width if that setting is enabled with the hpi controller.

I have had issues like you mention and a throttle recalibration sorted them out. Just do the std setup holding full throttle then power the controller, wait for the beeps, go to full reverse, wait for beeps and then let go to neutral. Should help.

hey,
I will try to go back to 1.24 and see if it fix my problems. I will update you in a short time.
I calibrate my esc every time after program it. and also tryed to bind the remote..dident work, so I tried a diffident remote and receiver from my friend but it didn't fix the problems..
its the ESC...
I will try 1.24 now and see if it fix my problems.

thank you !



UPDATE:

I switch back to 1.24, first run with charged battery...

1. The car lost power, and Punch ... acting very strange and took a long time to accelerate. The car did not have Punch power.
2. stuttered The vehicle .. like the Cut Off is approaching (batteries were charged).... didn't happened because I turned off the cutoff -that problem hasnt fix with 1.24 :(
3. Random vehicle brakes every 30 seconds or so -now only break when I drive in high speed and then pot the trigger back to neutral, and when the car is still moving press the trigger again...the sometimes the car put itself into break...and the I cant controlled it for 3 seconds.. like lost signal..
4. The motor started making strange noises and sounds like it opposes itself... make those strange noises when the car is acting like in 3 (when it break)
5. The ESC stopped to get a response from the remote for a few seconds every minute or so ... (after 2-4 seconds I managed to control it again)



same problems...I don't know what do to anymore...
Patrick, do you have anther idea how to fix this problem ? what am I supposed to do now ???

thank you !

Well you've ruled out firmware so it's either the esc's taken a dive or you have another issue. Remove the motor and check the drivetrain is smooth.

Next check your batteries and radio.

Last take Patrick up on esc swap.

Good old 1.24 always works perfectly no matter what ( not the smoothest start ups from zero rpms but it's damn rock solid firmware with no bugs ), does sound like either a radio issue or the esc is borked some other way...

I'm thinking Castle & HPI need a disclaimer on their sites warning about updating the firmware on HPI escs.

its not the radio...I tried 2 different radios and had the same problems..
the car drive train is fine.
I tried to use anther servo and still had same problems...
its the ESC for sure...

Patrick ? what can I do now ? what may be the problem ? how can I fix it ?
thank you !

Patrick's already said that if you send him your info he will get you a replacement on Monday. Not much more he can do.
