I dont think its the servos either.

It may not be. I was just testing things again and discovered with the aircraft system powered up but the transmitter not on the servos are not jittering at all. Once the transmitter is turned on the jittering starts. I tried changing from 22ms timing to 11ms timing but that didn't help. I have the rx connected to the SF16 via the SRXL port. I do have an SRXL2 rx I could try and see if that helps. Not sure what else I could check or change on the transmitter. The transmitter should be up to date as far as software goes. Not sure about the rx though when it was updated.

Are you using twisted servo extension wire or flat ribbon? The signal wire could be acting like an antenna. Perhaps a wrap thru a ferrite core might help.

I'm using flat ribbon cable for the extensions.

Try switching to twisted wire and see if it helps.

I'll do some more testing tomorrow. I'll unplug the tail servos from the Smooth Flite 16 and plug a couple servos directly into it without extensions and see if that helps. If it does I assume that means the extensions are causing the issue. I have a several ferrite rings I can try and see if that has any effect, if not I'll order some twisted cable and make up some new extensions with to see if it resolves it.

Thanks guys for the replies, and thanks to anyone that has any other input on this.

I think Baracuda hockey is using 737’s with great success

Dave Wilshere

Try 6.6v Li-Fe or discharge the Li-Po packs to 7.4v and try

If you decide to order wire get the PB premium or Maxi wire

Couple of things

I use 737's in the tail (well the whole plane really) with no issue on Lipo voltage with home made extensions. As Bob mentioned, they are Powerbox Maxi wire but other than the normal whine you get from digital servos there's no jitter.

Twisted wire works great for cross talk in communication and network cable pairs, for RC, eh.....lets just say the effect of twisted wires is more aesthetic than technical

The weird thing about Powerbox wire is its size. Its 0.35mm^2 which is in between 21 & 22 AWG and is not a standard metric wire size. So ,stripping it is difficult because there are no strippers of the matching size. I would cut some of the copper using a 22AWG stripper. I finally bought an Knipex adjustable stripper and seem to have the best results.
Regular wire, in standard sizes with PVC insulation is easier to get good results with and costs less but is slightly heavier.

Maxi wire has 2x 0.5 and white signal 0.35. You can just see the difference
Wire cutter, stripper use these they suit most gauges and repeatable

I would only used Premium not the max for the mini servo……premium was used on everything before the MAX was out….I used the max on full size high power servo…

I've been having some success with the Knipex 11-82-130 stripper:

I've had no success with a stripper named Yolanda...

I use Maxi on everything, we have been under spec on the wire for years, servos have gone up in torque and current draw, yet we have not updated the connectors or wire.
My Hot is run fully in Maxi

My Feedback: (12)

If I go with the Maxi wire do I need to buy the connectors they sell as well or will the regular connectors I have that I bought from Hansen Hobbies be sufficient?

My Feedback: (12)

Funny!!

My Feedback: (11)

You will be fine with Hanson Connectors

jvaliensi

My Feedback: (1)

The connectors Hanson and Powerbox sell are cheap imitations of Mini-PV 0.10" connectors made by Amphol (Dupont). They work fine but are not as reliable as the Mini-PVs.
If you want to learn more I recommend Matts Tech Pages:

DuPont and ?DuPont? connectors, and how to crimp them properly ? Matt's Tech Pages

In any case, the IWISS crimper is way better than the crimper sold by Hanson and others. Best $25 tool out there.

I had problems with MKS servo's in the past with extensions and unwanted jitters and movement. Switched to PB maxi wire and problem was solved. Been using it ever since.

I ordered some of the maxi wire this evening. Hopefully it will solve the jitter issue. Thanks to everyone that replied.

If anyone is in need of a CMjets fuel tank for their rebel let me know. Have a brand new one I (foolishly) bought thinking the ARF+ factory one was easily removable. Asking $150 shipped fedex 2 day CONUS only. Cost me over $200 and took a month to get to me originally.

rc_heli_flier

My Feedback: (12)

Tried that this evening, same thing with jittering. Thanks for the suggestion though.

The maxi wire will be here on Saturday. I'll get an extension made up and report back what I find.

Dave Wilshere

OK, good info. Not 100% the wire is the problem then, but it will be interesting to see!

Might be a PITA to pull one but plugging them in directly would eliminate the extension as the issue
