Hi guys; got the Futaba R.C. 4 ch. system installed in my Acc. IDA with the newly installed 1/2" oversize cylinders. I'm only using 2 channels to operate the throttle & the reverser, but after running a few minutes, the servo linkages start to "quiver" & then really start to move all over the place!!! Is this what's referred to as "glitching"? I know what most everybody is going to say; get a Spectrum system!!! I bought the Futaba sys. about 7 yrs. ago & it's been in the box ever since, so I figured I'd, at least, try & use it, rather than discard it! It's 75 mhz, so I guess that's the 1st. strike against it. I did use it earlier this year, on my Aristo mike, to just operate a steam whistle & I noticed that after running the mike for awhile, the whistle servo would start "jerking" & blow the whistle intermittently. This wasn't a problem there, as it didn't affect the running, because I was still using the original Aristo R.C. for that. I kind of thought there might be some kind of "radio wave" interference with the two systems being side by side, but now, with the IDA, that's not present. The only other thing that's common between these two installations is the presence of a water level detection system in each one! The mike has the sight glass (which we all know is not all that reliable!), but the IDA has nothing, & with that small boiler I'm not going to chance running it out of water!
I did some test runs today with the WLD system shut off, but ran out of daylight. I can't imagine that the WLD sys. module could be causing some kind of interference (it's mounted right next to the Futaba receiver in the tender I'm running behind the IDA), but I suppose anything is possible! Since I'm new to R.C. I sure would appreciate any help with this problem! Jim Spanier
