I don't know jack about radios. Having a one meter antenna trailing behind, doesn't help flying.


Thanks for your response.

Easy fix, just switch over to 2.4Ghz
What radio are you currently running? Does it have a removable RF module on the back of the radio?

Run it out to the tail and back. Or to the wing tip, stab etc. Any place to take up the slack.

Transmitters are Futaba FG Series, so yes to modules. How much for tiny 4-7 channel receivers? And can I still use old servos?

I'll try winding it around in various configurations, I was concerned that might interfere with reception.

It's the Cutlass (design by Tomcor, drawn by Firetrappe). Wingspan 20.5" Length including fins 18.5" Made from breakable foam from a Dollar store. Hand or slingshot launch glider.

being that it is a parkflier of sorts, you can purchase a cheap 2.4G RF module and receivers that will do the job.

You can coil it around something inside the fuselage, say a straw, just make sure not to overlap coils. Any overlap has the effect of shortening the antenna. Another possibility, as previously mentioned is to run it to a wingtip, then perhaps to the top of the vertical stab, then if necessary to the other wingtip.

A small plane, why not let it stream out the back? Wind takes care of the rest.

Why not run it out to the tip and then around the leading edge?

That's how I used to do my foamie stuff when they first started coming out and I was still running 72MHz radios. But seriously, There are too many inexpensive options for going to 2.4GHz radios now and IMHO that's what you ought to consider doing....

A radio, is a radio, is a radio. When you outgrow one or age gets in the way, sure, go shopping, but no reason to abandon 72Mhz to keep up with the Jones's. People go through radios more than they take them out to the field, and second hand "like new" is a bargain to take there experiment off their hands as they quest to get the "best."

http://www.wsdeans.com/products/antenna/2piece.html This is what you need. My advice is to advertise in the helicopter forums for a new or used one. I had good luck over at RunRyder web site.
