Coupla Questions

1. Does anyone know how to determine the length of a replacement antennae
for 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 plane
uses 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 outermost
positions, 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 seem
to work with the radio set on elevons. Is it possible to change the throw
using elevons, or do I have to take another approach?

Thanks

Steve

great (and sometimes not so great) words of knowledge:

1. 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.

2. 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).

Re: Coupla Questions

Check the manual for the Flash 5. I know you can reduce the rates and add
dual rates in elevon mode, I just havent used mine in a while and its in the
garage and not close to hand.
I had/have mine set up for dual rates on my 400X, but I havent used either
the plane or the radio lately due to experiments in airborne video.

Re: Coupla Questions

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

Re: Coupla Questions

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.

Re: Coupla Questions

If it is very sensitive recheck your CG.
