Hi Bob
You're wasted here!
Come back to where you friends are at Barton!
I've thought along the same lines Bob, as you say with the technology we have it shouldn't be too hard. I even have a copy of the Dale Kirn stunt model from the 60's or was it the late 50's.
I've got a stunt mono line actuator too!
Other stuff has got in the way though.
Cheers John
