In response to the last five replies....

exeter,

That's what I've always been told, and experienced in a few other incidences.

ual,

Futaba 7C. I usually do a range check with the engine shut off, Trans. antenna down, 100 ft. away. I know this may not be a good practice, but 75% of the time, I don't range check with the engine running. Luckily, I've never had a problem. This time, I didn't do it either. Luckily I only had a problem at WOT and got out of it when I started having glitches. I'll definately do some of the things you reccomended.

Mac,

The receiver is extremely well packed in foam. It is brand new, never been used. Although it is new, that doesn't rule out a faulty crystal. I'm going to check it by swapping it with another.

evfast,

I will start the process of elimination by doing that first. I have a strong feeling that's my problem.

Mecaloj,

I don't believe that's my problem. If I'm not badly mistaken, I had plenty of travel left when I was setting my end point. I will double check it though. Even if that was the case, I'm running a 1100 Mah pack that is fully charged, and a little load on the battery because of this isn't going to create the problem I'm having, I don't think. This was the first flight, so the battery was at max charge. I could see this being the problem if the battery was more on the weak side. Like I said, I'll double check it.

Thanks for all the responses guys, your input is much appreciated.

John
