Unfortunately, I can't get it into recalibration mode. It is looking as though there is something wrong with the high power/voltage converter. The low power stuff works, just not the high power stuff. I might have to speak to the shop.

I have a Kraton EXB with an EZRUN-MAX8-V3 ESC. My batteries got wet and one of them failed (my bad). I dried them out and managed to get the affected one working again. I spotted what looked like white lithium oxide inside the battery and decided that it was safest to bin it. Lithium being highly reactive with water and all. So I plumped for a new battery. I am now using one new and one old battery. My charger/tester shows all the cell voltages as being OK, as with the internal resistance, i.e. the old battery matches the brand new one. I'm running a discharge tested on them now and they seem fine. The Kraton will not power up. Normally when I turn the ESC on the motor and ESC will 'beep'. This is not happening now. The red light on the switch now flashes. I cannot find a mention of the switch LED in the instructions, only the LEDs on the ESC itself. I have put the programming card onto the ESC and it does not light up. However, if I disconnect the car batteries from the ESC and power the programming card externally, then the programming card works. I can check all the ESC settings and they match my choices. I have powered the radio receiver externally too with the ESC disconnected. I can control the steering using the radio, as normal. Incidentally, I tested the servo and it was fine (it is also brand new). With the ESC reconnected it powers and the radio still powered externally, then the ESC does seem to start and the green light flashes, the fan comes on, the steering works. Unsurprisingly, the motor does not run, because the supply is only 5V. So, what am I missing? When the battery popped did the ESC pop too? What does the flashing red switch light mean? Any other ideas. Commiserations welcome too... I'm truly hoping the ESC is OK or can be fixed. Rich

Welcome Shergar!

I think I have got it sorted now. I had set Option 2 for Item 1 on the programming card, as Tony suggested. However, when I had set up the throttle range I had the ABS turned on at the transmitter. I should have read the instructions more carefully as they clearly state not to do this. I turned the ABS off, then followed the set up procedure again. Now I have forward, brake and reverse. Does anyone know if I can use ABS with this setup? When I turn it on at the transmitter I lose reverse. Richard

Wow Basingstoke! Not far from me. When this COVID nonsense is over, we can meet and you can show me how to do this thing properly.

I have a Hobbywing EZRUN MAX8 with 2200kv Motor and an Absima CR3P AFHDS radio. I thought I had it set up for forward, brake and reverse. However, I can now only do forward and brake. I have gone through all the ESC settings using the programming card, and all the settings on the radio. I think they are right, but I cannot work out what I've done wrong. Any ideas or pointers greatly appreciated. TIA R

I'm new to all of this. I had a Tamiya Frog when I was a child. My brother and I saved up for one. We had a tin on the mantlepiece and put pennies into it. It took ages until we had enough. The local model shop was bemused, gave up counting our shrapnel and just took our word for it that we had given them enough money. Happy days! I've just put together an Arrma Kraton EXB. I calculate that it is 1004% better than I am. So I am learning. I chose this particular car because it will take a bit of abuse whilst I learn. I can also let my children use it. My daughter is clearly a natural. My son, who has Down syndrome, had a go too, but he prefers watching and cheering from the side-lines. My wife... well she's going to show all of us up. I might ban her from driving it to avoid embarrassment.
