Just wanted to share a funny way of taking care of the CL circle at the field while having a cup of coffee:  Laughing

I love it! But I have to wonder what the line pull is...have you performed a pull test to 10 Gs on your "control line?"

Can you mow inverted? Loops? Overhead-8s? lol!

It's all tied up in higher math Jim. Got to get the incidence angles right along with the CG. Smile

Thought it might work the other way around, wind the cord and let it unwind center circle out, but no. Unless............

rsv1cox: at my last job, more than 15 years ago we built remote controls, RC, for many different things. We got a government contract from a group that watched over a nuclear burial area. Where they buried nuclear waste. Under ground sealed with concrete, and all that jazz. But the ground above had grass and it had to be mowed. You guessed it we made a remote controlled lawn mower. We tried 915 MHz which is what we used for short range concrete pumpers and indoor cranes, but they needed a longer range so we had to use the old 27MHz frequency. It was a self powered lawn mower the kind with the hand grip that you released and the thing took off mowing. We had to rig up servos, big ones, to the wheels and a giant one to the hand grip. The boss tested it out in the business drive way running it up and down the parking lot. It got loose from him and hit one of those in ground electric boxes and he had to explain to the local electric company why there was a scrape across the power transformer, but all was well.
   The customer loved the thing and mowed the lawn remotely until the nuclear material fried the electronics, about 2 years later. They were going to reorder another RC lawnmower, but another electric bought them and deleted the requirement to mow the lawn and everyone live happily ever after.

  True story. No strings attached. We bought the self propelled lawnmower from Costco as I remember.

Mowing the CL field while drinking coffee :) Empty N.E.S.T. [i]New England Stunt Team[/i]

The N.E.S.T. New England Stunt Team is a CLPA (Control Line Precision Aerobatics) club located in the United States. Its members are mostly living in the New England area. They fly on Sundays from Memorial Day through Labor Day at the Wrentham Massachusetts (E. MA) State-owned fairground field(s)

They've used that same type of self-propelled mower on a tether to mow a 70ft. diameter circle from the outside-inward. I've seen the mower/tether/post in a storage shed at the field. It's funny.. really. Laughing  We C/L people are wildly creative.

If you happen to stop by their field on a given Sunday.. there's usually a good group of fliers there.. plus mechanics.. cooks.. helpers.. medics..  Laughing They're a friendly bunch!
