f2k plans from rlt?

I bought plans from him quite some time ago now and built a great treb by scaling his plans by 2. Does anyone have those original plans anymore? I don't mind buying them but was looking for them so I could let a summer camp instructor use them this year.

Re: faw or rolling axle whipper

Gotcha! I was so hung up on FAKA, I forgot you were doing a FAW or RAW. You need to be concerned with stretch of your trigger line more than anything. I would suggest a thin steel cable permanently attached at the middle of the base and have a small loop at the other end. It looks like you have that...

Re: faw or rolling axle whipper

I'm still a little unsure of what you mean. I have the primary trigger which I pull to start the CW falling forward. When the CW arm is about 90 degrees to the throwing arm, I have a secondary trigger which allows the throwing arm to be released and then it can spin around pulling the sling behind i...
