<DIV><BR></DIV>First, I just want to say thanks a whole bunch to the people who offered me equipment as I've gotten some private e-mails also. It really goes to show how great people are in this hobby. I am, however, going to go through local sources for different equipment. There are a lot of people at my club with plenty of different TX's and RX's in all different brands so instead of trying to rush and get things here so quickly, I would rather get them locally first. Thanks a ton!! <BR><BR>Next, I want to reiterate my set up because I think this is getting a little confusing.<BR><BR>My current set up which shows NO visible problems is: <BR>-Futaba 9C with the syntheszed module.<BR>-Hitec Super Slim RX on channel 49. <BR>-2 Futaba 3010's.<BR>-2 Hitec HS77's.<BR>-1 Hitec HS81MG.<BR>-Duralite 2s2p RX Battery<BR>-MPI 5.6v Regulator.<BR>-MPI HD Switch Harness.<BR>-Cermark gold plated extentions.<BR><BR>Now here is my problem set up which shows the glitch: <BR>-2 JR 9411sa's<BR>-1 JR
8417<BR>-1 JR 8411sa<BR>-1 JR 3421sa<BR>-The rest is identical.<BR><BR>As you can see, the only thing that seems to make it work is the alanog servos.<BR><BR>Del, they glitch when they are connected and disconnected from the surfaces. More so when they are connected, but I can totally rule out the airframe being the problem. These servos have at least 2 years of flying on them and one of the hypothesis I had was that after being vibrated around for 2 years, theyre now feeling like they should always be doing that, even without a load. Not sure if that's possible, but I'm just throwin out ideas. <BR><BR>The next thing I am going to test is a Futaba PCM receiver on both set ups. The set up that works will be in the aircraft, and the set up that doesnt will be sitting in the foam transmitter box.<BR><BR>***Important*** <BR>Yesterday I range tested both set ups. The one that "works" is in the plane, and the one that doesnt (JR digitals) was in the transmitter box. Both tests were done
outside on grass. I put the antenna all the way down and walked at least 300 feet with no noticible problem at all when testing the airplane. When testing the digital servos, I was able to walk about 100 feet from the box they were sitting in and thats when they became very noticible glitches. This was both with the antenna at 1 section out, and all the way up. The glitch was reduced when it was all the way out but it was still prevalent. <BR><BR>

It would be worth checking, but if he has another Rx he could just substitute that (probably already did) and see if the problem goes away. Scott P.: Does moving the antenna change anything? You have to find the common denominator. If it's not the Rx then maybe it has something to do with the installation. There is something going on there and I'm not sure why the digital servos make it more apparent. Find someone who knows how to use a 'scope and see if they can help you. This is weird - you guys have the same first name and my last name looks like yours. Maybe we're all stuck in the Twilight Zone...</SPAN></FONT></P></DIV>
