In my 1/12th which I am currently having the problem is a LRP QC2...originally the problem started happening with a Novak Atom in my F201.

Once I replaced my worn out batteries in 6 cell I had no problem with the QC2...and 4 cell indoor I had no problem with it as well with the new reciever.

Well, if you run the big power cap on the QC2 it's not really an issue if you run an SR3500. I've had some issues with the Tekin Mini Rage brushless system. When I ran it with an SR3000 Standard Receiver, I needed to run the Voltage protector to prevent cutting out on power. Once I switched to the SR3500 everything was fine. I've had very good luck with the HB Hara Twister 2/KO Propo VFS-1 and the Novak GTB/GTX.

Try a power cap on it, plus the voltage protector.

Ok, since I have the SR3001, where can I get that receiver voltage booster?

Any issues with Keyence ESC's?

Well the whole reason to run the QC2 was so I wouldn't have to run a big power capacitor on the ESC...running one on the RX isn't any different in my book. So either way it sounds like we gotta run a big ugly cap somewhere. Well I think in 1/12th I've solved the problem by essentially using the battery (since it's only 4 cells) as both the main power source and the RX pack bypassing the BEC. Even if the voltage peaks a bit higher it will be fine since the Spektrum can operate at higher voltages...then the only real concern is the servo.

There's the voltage protector.

I haven't heard of any Keyence issues, but I am pretty sure that is what Adrian runs, or at least has run in the past.

Honestly, I can't really think of one high-end ESC that you really don't need the power cap for or that it isn't reccomended. One of the reasons why ESC's have continued to shrink is that larger capacitors are being removed from inside the casings to outside the cases. Like I say, I run the KO/HB ESC's and run dual caps on those, and I also run the GTX too which has a single power cap. I guess I don't see the issue. Even if I wasn't running Spektrum equipment, I would still run a power cap because I like what it does to the feeling of the throttle.

You're fine with running a bit higher voltage. The Receiver will regulate the voltage sent to the servos.

The LRP doesn't need a power cap, though you can run one, and it is as small or smaller then anything else out there (smaller if you include the size of the cap in the footprint). Personally I don't like them because it's just one more component to mount that can fall off, snag on something, or cause a short. Setups look much cleaner without them. In the case of the QC2 I haven't felt a need to run one...it feels just as smooth without it and performs just as well for my application as any other high end ESC, except for the power problem with the Spektrum.

Keyence doesn't need a cap..... :sneaky:

So I should have no problems then using a Rapida? No need for the voltage protector? :confused:

I have seen guys run caps on Keyence ESC's. I've even seen guys add power caps to older Tekin G12cIII's that were running 27mhz equipment. Again, it's to smooth things out and to provide more punch. A side benefit of running the power cap is it does help prevent the BEC output from dropping too low in high current drain situations, like when you accelerate. I've been running multiple power caps on ESC's since I first started running the GM V12WXC like 4 years ago, then with the VFS2000, onto the VFS1, QC2, GTX, and GTB. It's not that you have to run a power cap if you run Spektrum. It's a feel thing and I personally prefer running power caps on my equipment because I like the throttle delivery and acceleration with them versus without. Think of it as just another tuning aid.

I'd say try it without first. It's not that you must run the voltage protector in every application. I think on the Keyence, you can adjust the BEC output voltage, just as you can on the KO VFS-1. I haven't run one personally, but I would check in the Keyence thread to see if someone knows for sure

"AdrainM" is very knowledgeable on the Keyence's, so he could give you a definitive answer. He's from Schumacher USA so you can usually find him on the thread "Schumacher Corner"

ok im getting a airtronics m8 backlit version and im gonna put spektrum pro in it any problems i should know about or what to do or any tips please let me know
