Sorry ment cheer not cyber. Autocorrect on my phone

Cheer Dave. Yea I would agree with you with. But the remote is the old f14 on 40megs, I've also tried two different TX a d rx encase that was the fault. Ive seen people having fault on 2.4 with this esc too which would make sense.

HI Tim
I didn't mention the Manufacturer before but it was a newer Futaba set that had low output pulse voltage problems. Earlier offerings from the same manufacturer worked fine. it is easy to blame the ESC when in fact the cause may be elsewhere. Electronics like computers advance so quickly that it is difficult to keep pace and what works today sometimes doesn't tomorrow.
If you have an electronics guru in the club then the circuit for a servo cleaner is on Tony Roons site, bit old now but works fine.
Articles on the net can sometimes be a bit biased, and uninformed. it is easy to criticise, but in my opinion negative comments are often made in the heat of the moment. Electronic bits are totally alien to many people and even the more savvy can be frustrated at times. Good to see you belong to a club, at least you can find help from others who may have had similar problems.
Just a thought - do you have any other radio sets you could try? Might help identify the problem. 😀

Cheers Dave, I thought the same so I removed the mixer and wired directy into the receiver. The radio is Futaba f16 and matching receiver. I been looking at a lot of site on the net and there steels to a general fault with the esc(great more money wasted).

I try cutting the power cable down and resoldier the joints. Tonight and see if that helps

Thanks again

HI Tim
Reading the posts it now seems possible that there is a mismatch between your radio receiver and the connected electronics. What radio equipment are you using? The cutting out at full throttle is something I have experienced with Mtronik controllers and as, like you, it can be resolved by changing the stick travel, I suspect the cause is the pulse output duration or voltage of the pulse (probably too low).
I have built switchers that worked with some sets but not others. That was solved by using a pulse cleaner (or servo reverser) between the receiver and ESC. Such gizmos were sometimes necessary in larger models where the wiring had to travel some distance, and was likely to pick up interference from the high power circuits. Each manufacturer designs its equipment to work together and whilst there is now a common pulse width, modern electronics uses lower voltages and current to operate, and the interfaces do not always match between different manufacturers.
I am not familiar with the Astec mixer but have used the Action. The system worked well until I changed the ESC's to self set up ones. I solved the resulting problems by using two separate batteries for the motors and a separate radio battery.
I suggest you check with the supplier of the jr 50 amp escs that they will work with your proposed set-up. 😀

thanks for the advice, I've done would you advised but the the motor are now cutting in and out on full forward but reverse is fine. if I plug in with a y lead the same and I have to program the tx to only travel 50% of forward throttle to stop this.think I cut my loses and buy another two jr 50amp esc as I know they will work

the delay look's like one is not set crectly to nutral I make a short extension lead up with the red wire taped up that way you can plug the speed controlers in with there bec BUT one at a time when they are both set then plug both in with the short extension in one lead, much easeyer to set them up leave the mixer out till both are set then put the mixer in. I found this the best way and have set a few up , not used the astec but used the ACt-something one and the very goood hunter one.
