I'm hoping htere is an easy solution to this. I havw just installed an new Orca B32 and Blitreme 17.5T combo in my Lazer and nneed to calibrate it to my Sanwa MT4S / 462rx. The instrustions just say to have the tx at full brake, turn on the ESC and it will beep twice, then go full throttle and it will beep twice, then neutral and it will beep once and its done. The car won't run at all.

Mine doesn't beep

I have tried changing the tx throttle channel to rev or nor but now differemce3

Anyone dealt with this before?

do you have the sensor wire connected between the motor and ESC ? And if so make sure they are fully seated.

and it could help to rebind the receiver to the remote. The radio should be in NOR mode.

The manual says throttle in rev but then to try both if it doesn't beep. I will check all the plugs again, the sensor wire is one that was already in the buggy so was working last time out. I tried a couple of rx cables to rule that out too.

I will rebind the rx/tx today and hope. This is always the worst part of a new esc/motor, it either works first time or takes ages to get right

The reverse function is usually used on Futaba radios. But one thing to check is that your motor wires are soldered on the correct tabs. That ESC has a setting option that can switch the order of the ABC tabs, so while you may have wires going from ABC on the ESC to ABC on the motor, it can actually be reversed if the setting is incorrect on the speed controller. You'd need the program box to make sure its in the correct order.

If you don't have a program box to reverse the setting, you can try reversing the wires physically by swapping the A and C wires. If that works then the internal setting was reversed from the factory or whoever you bought it from.

Thanks, will give that a go too. The motor doesn randomly run forward and is fast so I think the A B C are ok. I saw that mentioned in the instructions but assumed the factory would have set it to A B C...then again should I assume anything...

So I have tried the following so far, and no joy:

rebind the tx/rx
tested the sensor cable (all 6 wires are connected, have continuity according the my multimeter)
Tried with throttle both NOR and REV
Checked the A B C, I have them soldered correctly and the ESC is set to this, not the reverse
tested 2 rx cables in case the new ones were faulty but they power the rx fine

It never actually beeps, even though the manual says it should. The lights may flash differently (red first then blue when its in NOR but only blue in REV) but this isn't mentioned in the manual

The motor will spin randonly, then if I go full brake it makes the motor full speed, if I push the throttle then the motor stops. Its weird, when i hadn't setup other ESC in the past they still worked mostly, just a bit erratic at times.

This was bought new and all soldered up ok so i expected it to be a lot easier than this

in that case you may want to try to get in touch with the seller you bought it from to see if they can help you get a replacement. Though I'm concerned since you said you've experienced somewhat erratic behavior before with your transmitter on other speed controllers. You don't by chance have an old radio and receiver, or maybe a friends that you can put in and try again. Because if the receiver is glitching then the speed controller won't really know when to calibrate. That's just something else to try before doing an RMA. Because if you do it'll most likely need to be sent to the distributor in Canada for replacement, depending on where your seller got it from.

Thanks, this was what I was hoping to avoid!

I am probably overstating the erratic behaviour previously, it was just a once off when the car was first turned on until I calibrated the ESC. I have a few other rx/tx I can try. I use this tx on my 4 racers without problem, so the tx is fine but this rx could be the problem.

if when you turn your esc on with full battery and hear no sound from motor then . theres only 1 thing it could be . non working esc.send it back. even if in wrong throttle or radio position it should beep

no, it could also be a esc cable plugged in backwards to receiver, radio not set properly,ie: not set to 100%, rev/normal not set right. RC guy spews bs info in about every section here. best to put him on ignore. The ESC could be defective, yes, but to tell him that, send it back and have them say it checks out fine because of your mis info without checking ALL the options first is ir-responsible at best!

esc should make noise no matter what ur saying. ie rx plug in backwards. cable whatever. no noise bad esc thats it https://teamorca.shop/products/preor...-2017-oesb32lc

If its receiving signal properly and in calibration mode it will make a noise that true, but if these things are not set correctly it will not make a noise because it does not go into calibration mode. The esc may be fine, just doing as its told or not told. He also did not seem 100% on motor wiring-- A-B-C. That also wouldnt let it go into calibration mode- no noise. but esc is fine. when things don't go right and your relatively new to these things, it can be that palm to forhead moment that gets ya.

May not hurt to take it to track or hobby shop and bite the mental bullet and have someone else look at it too.

Ok so I swapped in an RX from another car that was easy to setup. Also took that rx cable too, as while I had tried 2 they were both new and this one definitely works.

The ESC doesn't have the markings for sensor, + and - so i have turned the plug around and its definitely in the right way. Nothing works when plugged in wrong, but at the moment the steering works and the motor sometimes goes, but its like its getting intermittant signal.

The rx bound fine, as expected.

I've also cleared the slot on the TX so everything is back to default and then went from there.

The battery is currently 7.83v so not fully charged but enough that it shouldn't be an issue.

The ESC has never beeped, but when its set to NOR mode and I do the calibration then the light flashes red twice when I would expect the 2 beeps, so it appears to do it just with lights, but then it doesn't work.

So I've tried 2 rx, REV/NOR on tx, tested the sensor and rx cable, checked the A B C and tried both ways with the program box.

It looks like I will need to contact the seller, luckily hes a good guy and should be able to check it over for me, and organise a replacement if its the ESC.

Next race day is the 17th so I've got time and I can at least swap the old gear in to go racing

I hope you manage to get your replacement quicker than I got mine lol it took a little longer because they had to wait to receive the bad unit before sending the new one, but the Speedo is worth it.
