Running direct power shv500v2 with new 1080g2 ESC

[high plains drifter]

My old Traxxas Xl5 has a 2-pin JST that accommodates the direct power plug from the servo. But with the 1080g2 I need to find out how to run this servo. Should I make or buy a 2-pin to 3-pin adapter and plug it into the receiver?... or if I still run it through the ESC, then what do I need to do since it's not plug-n-play. Thanks much for the help.

its a direct power servo run it off the battery

Its typically run off a JST lead soldered to the power connector so it gets full battery voltage. You might need to remove the connector first so you can add back heat shrink (if it uses it).
If you have access to the positive and negative solder pads on the ESC you can solder it in there too, that can clean up the wiring a bit.

@ HumboldtEF- Ah... I was too slow and missed your post. Got it. Really appreciate the help. I know it's kinda a dumb question but I didn't want to fry anything and I've seen video of a guy running direct power to the rx... not sure the details but didn't want to just assume that was advisable. Thanks greatly,, to you and @ferp.

No problem, I posted 1 minute after you. Not sure how it ended up above yours, weird.

I wouldn't but I suppose you could run direct power if your receiver was getting enough voltage but its usually only getting 6v or so. For me the point is getting the max power with 12v-14v. You'd have to add a BEC in order to feed the receiver that much voltage (which it might not like) and the other point of direct power is not needing a BEC so it would be really silly to do that.

Glad I asked. I'll solder a jst connector into the batt leads to run the servo direct. I thought that running direct into the rx might be a bad idea just for the very reason you stated... confirmed.

Didn't want to start a new thread but if anyone is checking in here- I've only ever run 3" esc to rx extensions. I've got a 6" ext that I'm figuring on using but I only need 3". I hate having more length of wiring than necessary but I can coil or bundle it and live with it.

My question is for those that have run 6"+ extension for esc/ rx, are there any inherent issues in going with a longer extension? Besides the xtra clutter of course. Signal fade or lag?... potential glitching? These might be dumb ideas but I was just curious if there's any benefit in buying a 3" ext. as opposed to just using the 6" that I already have on hand.

Its probably fine but this is an additional connection point and an extra potential failure point in theory. Though in practice I cant think of any instances where a servo connector failed. Ideally you would solder in a new longer wire but most ESCs are potted and dont allow for this.

I often shorten wires with new servo plugs and pins. That does require a special crimping tool. But it can be nice when you want to clean up wiring.

I'd say just coil it up and dont worry.

Oh and I just remembered there are wire locks out there that secure the extension connection, probably more needed with drones, planes and go fasts though.

This extension would be for lengthening the ESC's JST wire that plugs into the receiver. I do think though that I'll just use the 6" and be done with it. The additional connection points will exist regardless if I use the 6" or buy a 3". I just don't care to have longer wiring than necessary but this time around, I'll just coil it up and try to keep things as tidy as possible.

For what it's worth- I went ahead and made a JST direct power adapter to plug the servo right into the battery lead. I've made several before but since I wasn't familiar with the 1080g2 and since I wasn't sure about other possible alternatives to powering the servo, I wanted to ask. But yep.. got that all soldered up and glad I double-checked here. Thanks greatly again, HumboldtEF.
