Ron, What is an X8 module?
Terry, new aerial... What could go wrong with an aerial?
Appreciate the replies. Cheers, Rob.

As Terry said, check your antenna first. If you go 2.4ghz for airborne equipment, then you would have to change your vid Tx & Rx to 900mhz, 1.2 ghz, or 5.8ghz.

I think you will find that the cost of replacing your JR plug-in RF module is less than the cost of a tuneup/repair. Plus, a lot of hobbyists have moved to 2.4Ghz R/C, so used modules (and entire R/C Tx's) are often sold at bargain prices.
Thanks guys. I am thinking about getting a Futaba 9C instead, although, a second hand one. We use 36MHz in Aus. Does anyone know if the 72MHz US radio's antenna is that same as the 36MHz version used in AUS. That is, if I buy a radio from the US and buy a 36MHz module, will the antenna be as well tuned as if I bought a set locally?
Also, what is the difference between a 9C and a 9Z?
I take it these radios are able to easily physically change btw mode1/2

Well, I would never have believed it, but I think it may have been the antenna !!!
I have had no glitches since. Having said that, I havent had too many flights. There is also one other big factor: In the time it took for the new antenna to get here, I have changed to 2.4GHz Vtx. I will retry with my 900MHz Vtx (10mW and 500mW) soon and report back. Hopefully everything will be apples.
As a matter of interest, I have great Video reception (2.4GHz) where I live (rural), but nearer to suburban areas, the reception is REALLY bad. I have only tried the one channel (Airwave 633module on ch4). Is changing channels likely to help much with that?
