Status: offline 		Is it correct that carbon fibre pushrods in a model can affect the operation of the receicer if the aerial is placed near them?
I have two .2 inch carbon fibre pushrods (length approx. 15 inches) in a fibre glass fuselage where the receiver aerial is running more or less parrallel to those. The distance between the rods and the aerial varies between 2 and 4 inches - should I be concerned?

Are there any guidelines about placing carbon fibre and receiver aerial near eachother?

regards,
Henrik.

Here in United Kingdom most of us still use 35 MHz.
With your info and a thorough range check everything should be 'GO' then!
