*sigh*.... just as I was on the way to the Post Office, I received a call from the LHS... They just received the replacement TX aerial in stock. I decided to try the replacement aerial first before sending it out...
On replacement of the aerial, I noticed that the wire runs extremely close to the chip, and at certain angles, will foul it quite badly. The new replacement lead was quite a bit longer, so it would have a lot more clearance in that area.
Tried it out with the gear installed, and seems to have fixed the problem

. I wll try it at the track and keep you guys informed.
<fingers crossed>
