Mojave Spektrum 160a - No BEC 7.4V option?

[Knightfall]

I have a Spektrum Firma 160a in my Mojave EXB and I installed a Savox SW-1210SG which is 7.4v. I have the Spektrum program card and my ESC only shows 6.0v or 8.4v. There is no 7.4v. I can a firmware update which jumped me from version B3.09 to B4.12, but there is still no 8.4v.

The servo works on 8.4v as a bench test, but I don't want to push too many volts to it and harm my new servo. If I keep it at 6.0v, will I damage the servo from not having enough power to resist the bumps and bashes to the RC?

No 7.4v on the 160a esc.. it will just be a bit slower and underpowered on 6.0v!? Can't really recommend you the 8.4v seeing how it will eventually burn it up or possibly create havoc within the system!!?

I found this I don’t know if it helps but the savox info says 6v is no problem

savox’s website says the servo can run on 6v

Oh shoot, you're right! I saw that a couple of days in the servo's manual when I was installing everything but since forgot and was thrown for a loop when I was trying to find the 7.4v.

I suppose I'll stick with 6.0v to be on the safe side and monitor how well this beast of an RC (I've only had it for a few days and ran it twice). Thanks!

Keep up on the maintenance and cleanliness and it will last forever!! Lets see it anyway!!

Is it too late to exchange the servo for something that can handle 8.4V?

Unfortunately, yes. My local hobby shop has a no-return policy. They claim it's a norm for a lot of hobby shops. This servo acts very well on 6.0 though and didn't give me any grief when I was running some light bashing yesterday and learning how to drive a 1/7th scale from my 1/10th scales.

Here she be!

In a Facebook Arrma group, a couple of people just responded there saying they over-volt theirs. One fellow has the identical servo as me and was running his on 8.4v the past 10-12 runs without issues. But like you say, will it be okay after 30 runs? Hard to tell.

I'll keep mine at 6.0v, for now, to be safe.

I ran my 160a at 8.4V, and my Amazon 25kg servo quit working before the first full battery after working fine for several runs at 6.0V. I won’t be exceeding the voltage rating of any servos again anytime soon.

Sound advice.
