1. Does anyone know how to determine the length of a replacement antennaefor a receiver? I've broken one and want to replace it. It's channel 50.Also, what should the gauge be?2. I have a Hitec Flash 5 radio system on a Zagi electric plane. The planeuses elevons, and in my one flight, it was VERY sensitive to the controls,especially for a newbie like me. The pushrods are set on the outermostpositions, but the throws are still pretty large. I know I can set the EPA(end point adjustment) on the radio to minimize throws, but it doesn't seemto work with the radio set on elevons. Is it possible to change the throwusing elevons, or do I have to take another approach?ThanksSteve

On 7/18/2003 12:36 PM Ted shuffled out of his cave and grunted these great (and sometimes not so great) words of knowledge:

Antenna length is USUALLY 39" overall length. It should be 22 gauge wire with about

15+ strands. If it is a HiTec, I would suggest sending it back to the factory.

First, make sure the pushrods are set as close in as possible at the servo and as far out as possible at the control horn on the control surface. If this does not reduce the throws enough, look in your manual for the transmitter under DUAL RATES. This USUALLY allows you to set a high and low rate of throw (a percentage of what you presently have).

A receiver anteena length is not critical. Just measure someone else's and you're good-to-go.

If it is a Hitec rx, just send it back to them. They usually do fixes like that for free.

Regarding the control throws, try using dual rates on both the elevator and ailerons to reduce the throws. I have used the same setup on an FMA razor but can't remember exactly without rereading the manual and doing some experimenting.

If it is very sensitive recheck your CG.
