RE: Meh, bleh...
When I get major burn out like you seem to have I start building something that has nothing to do with pattern/3D. I found some small stick an tissue planes to build and forced myself to build at least one of them all the way. This is where I first started building planes and it is amazing how I started to remember when times were so much simpler and how back then I could have never guessed I would be flying the planes I have now. People wonder why there are no more pattern fliers than there are but when you think of the amount of dedication needed to be competetive not to mention money and time then it is not to hard to see why pattern is so hard to stay with.
Another thing that I do is try to remeber what it was that was so much fun and interesting enough to keep me in r/c for 30+ years and go do that. Go to different hobby shops in other towns or go to the flying fields in different towns and get a breath of fresh air about the many aspects of R/c.
These are the things that I do when I get dug in to far...maybe some of these things may help you...good luck!
