Lite Stick Rx Antenna

[RS]

Just finished my Lite Stick. What do others do with the (long)antenna wire hanging out from the Rx? Just let it trail out past the tail section? Would think it causes a lot of drag but would be interested in what others have observed. Thanks.

I wrap it around the fuselage and let the last 6" or so hang off the tail. I know others who run it along the LE of the wing attached with tape.

You could replace it with a base loaded antenna.
Search the web for "Tony's Fly Wire". It gives details on how to build your own. I hate dangling my antenna.

:D

Here's the link: http://www.uoguelph.ca/~antoon/gadgets/flywire.htm
I have the Electronic Gadgets page bookmarked. It has a lot of useful information.

BTW, my newer GWS R-4P receiver came with a 19" antenna, so I presume that shortening the stock 38" antenna to 19" would not appreciably degrade performance or range.

Mine came with the 19" antenna and it had virtually no range. I extended it to the recommended 39" and now I can speck out my planes.....

For what it's worth, Jim

Maybe I should do some experiments with antenna length and range testing.

Would be interesting to learne what you would find.

If Tx/Rx range was better at 39" than, say, 19" then the following could be true: (1) the Rx freq. is tuned slightly higher, or (2)the Rx and Tx are not completely tunned/aligned to each other. The laws of rf propogation are such that the length of an antenna (at resonance) decreases as the freq. increases. ('Loading' an antenna can make it even shorter while still be at resonance).

With our very small Rxs I suspect that it is a matter of insufficient Rx tuning that people experience when range is short. I have read that mfgrs. tune their Rxs at about the middle of our freq. spectrum (e.g. about Ch40). Don't know if this is fact, but makes cost sense if they do.

Well, my freq/Ch info wasn't too far off :). Thanks. Good to learn Futaba tunes further than just at mid range of our freq/Ch. spectrum. I suspect that JR and Air (both mine) do same as well as others. As you have aluded to the capure ratio is a major factor in Rxs but it will always be best obtained with resonant antennas.

For what it is worth Futaba splits at ch 39. they tune mid way lower and upper. The Rx wire is more signal capture than resonence. Thus the longer the better within reason. 30 is normal for most Rx,s. For our use the Tx is where resonance length/tuning is a major factor. :)

GWS make R4P receiver with JST connector version with lighten ant.

It will be 3.6g full size 1M(38in)ant can fly at outdoor aproximate 1000feet useable range.

You also can cut ant wire to be 50cm(19in), the weight will be brough down as light as 3.0g only. For small size indoor with 500feet usable range should be more than need.

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. While in USA you have 20Khz channel spacing, GWS R4P should be OK for all conditions.

May be GWS not so well known, but we make a lot of OEM lables for many famous "BIG" companies world wide. you can see more information about GWS from: http://servoman.hypermart.net

GWS always try to make RC easy & affordable. Pls keep inform us what your dreams, let's make it to be true together!

Thank you for the information. Your GWS web site looks great. Have logged it for further review. Plan to get the Tiger Moth as my next electric.
