radio interference

[KSU Flyer]

Has anyone had problems with interference between planes or flying in a certain area that causes the plane to crash. In each instance (witnessed by myself and others who have had similar problems) the elevator locks into a straight down position. The people having problems are using Hitec feather recievers. Also, I might add that the channels aren't close together when this happens, so I don't believe frequency "bleed over" is the culprit in these instances. What is crazy is that it seems like the transmitter being turned on isn't a problem until the plane for that particular transmitter is turned on and flying. At this point the plane with the problem might have interference or it may not. I know it sounds a little crazy, but I've seen it happen with some sort of regularity. Any advice/help would be apprieciated. Maybe the solution is as simple as getting rid of the Hitec recievers? I don't know.

Thanks in Advance

The feather is a good receiver if you fly alone with a parkflier. If you fly with friends get something else. I have had good luck with GWS 4r-P receivers with channels at least 2 apart flying with friends. Some people swear by dual conversion when flying with others. In this case FMA Extreme seems to be the receiver of choice for Micro-Flight applications.

GWS make R4P receiver with JST connector version with lighten weight anttena wire.

It will be 3.6g full size 1M ant can fly at outdoor aproximate 1000feet useable range.

You also can cut ant to be 50cm, the weight will be brough down as light as 3.0g only to fly indoor with 500feet usable range.

GWS R4P receiver should be one of the best among this size and weight. This receiver was ditributed even better market share in Europe, since it is the first on in this size which can past 10Khz channel narrow band seperation. That you may fly together with many others without risk like some other light receivers which need 50~80Khz channel spacing.

In USA 72Mhz channels were spaced by 20Khz. So that you fly R4P together will many friends without problems with interference between Channels. However, there is another problem: Too many airplanes can fly in the air together, you might prety easy to hit others! :D So, need keep very attention to avoid this happend, that's really embarisment. You need prepare GIFT & SWEET WORDs ready for appology! :D

Fly safe, Happy landing instead of crash! :)

KSU,

I've had the same problem with Feather recievers. Best I can tell, some of the high-powered transmitters can cause this on ANY frequency. There are several guys who fly with me and I've noticed that when my plane is near THEIR transmitter, it goes wacko! We notice this more becuase we fly indoors at least once a week. I have since switched to GWS R4-P recievers or HiTech 555 Dual Conversion recievers. Try to watch WHO you are flying with when this happens. I have learned over time that there are about three guys (transmitters) who I simply CANNOT fly with.

Hope that helps,

I've had problems indoors with Hitec Feather receivers (my plane suddenly passing control to someone else's transmitter). No one was operating on an even close frequency. I've begun switching to FMA Extreme dual conversion 5-channel receivers ($49 + crystal) for any plane that I might fly in the vicinity of others. For planes that I fly only in my neighborhood, I'm still using my Feathers. I don't have the exact weights, but the Extreme weighs only slightly more than a Feather, but is lighter than a Hitec 555 (I don't know how much). Many people remove the case from the 555 to lighten it still further. I think that the Extreme still weighs less than a caseless 555. Until someone comes out with something better, I'm going with the Extreme because it's light, small, and dual conversion.

I believe the Hitec feather recievers are only good up 500 feet. and do not do well around large flat objects like walls do to bounce back.
