Well - I’ve put it in the optima and plugged everything in and it is just beeping 🙈

Thanks - unfortunately I think you are right. It won’t be the BEC as I only have one servo / I’m running this in a Wild Dagger. I’ll pop the ESC into my Optima which has a 13t Reedy motor which should be fine with the limit and see what happens!

It’s an 880 that I’ve got! If a cap pack would help I’ll get one 👍🏻

So - I got myself a second torque tuned motor - 25T, I believe, and fitted them. All was good for about 5 minutes and then it cut out. Any other ideas - I think I have a duff ESC. I have a 13t motor in another car - I might try the ESC with that and see if it fails.

I do wonder if it might be better with a lipo - only problem is - I don’t have one - or a charger!

The 880 is also a 12t limit, but the manual says that if you are running dual motors, the limit is doubled - so 12t single but 24t dual. It is odd because a number of people on here have posted that they have successfully run 15t motors on an 860 or 880. Mine is in a Wild Dagger - don’t know if the gearing puts more load on the motors / ESC?

Right - thought I had made a breakthrough! Checked with the program card and it was set to Lipo 🤦🏼‍♂️, however after I changed it to nimh, it still cut out. I have tried all settings on the low voltage cut out setting and it still cuts out - even if I disable the cut out. Conclusion - the turn limit issue must me the cause and others have been lucky! Thanks for the help!

Even if the motors are outside of the turn limit?

I’m sure that I set it to nimh - I’ll double check

Thanks for the comments - I am running 7.2V nimh, not 2S. When the car stops, which is very soon after starting - the ESC beeps and cuts out - it’s not overheating as it has only just started. I can only presume that it is the current.

Thanks for the reply - I don’t seem to have much luck with ESCs - my 1060 went into limp mode constantly with a 13T motor so I added the cap pack. I don’t suppose I can complain - the specs say that for dual motors it should be 24T+ but it is odd that others have managed it! I’m on the stock pinion too. I have just tried failing back the punch with the program card but it still cut out. Looks like a pair of Torque tuned motors for me!

I have tried 2x CoreRC 15T motors with my 880 and it cuts out (although someone on the forum has managed to run 2x15T Firebolts on an 860). Are there ESC settings that can reduce the chances of it overheating? Thinking about the punch setting - if that is turned down, would that reduce the current draw on acceleration?

Hi Cephas Reply to an old thread - what ESC were you running with the 12T 550 motors? I read on one of the threads about 2x15T HPI Firebolt motors being run off a Hobbywing 860 but I have just tried 2x CoreRC 15T motors with my 880 and it kept cutting out. Based on the motor limits on the 880, I can see why it cut out, but others seem to have managed it! I am trying to get a bit more speed out of it and the best idea I can come up with at the moment is 2x Tamiya Torque Tuned to keep inside the turn limit of my ESC (24T as two motors) but that isn’t going to set the world on fire!

Hi I have just picked up an old Reedy Ultra Series motor off EBay and one of the endbell screws is missing. The other one measures as about 2.5m x 7.5mm - can someone confirm the screw size? Definitely smaller than an M3… Thanks Nick
