Title: Control line electric model
Post by: GuyOReilly on May 18, 2021, 10:21:51 AM
I know that we fly RC, but what if I was to construct a small control line model.
The model would be using electric motor with a cut-off (yet to be designed).
Would I be able/permitted to fly C/L at the club?
Of course these would not be in front of the runway, perhaps more to the south-end of the field, behind the "facilities", when all is re-opened.
Thank you.
Guy

Simplest way to do the cut off is to use a receiver and transmitter.

There is also this project by one of the Balsa Beavers members:

Thank you @pmackenzie .
Interesting setup with a board that controls the flight time.
Auto shutoff.

That is normally how it is done. There are a few commercial units available.
Working with Kim Doherty we produced one, even sold a few.  I still use it in a couple of models.
It was very easy to adjust motor RPM, but designed for a fixed flight time that was not so easy to change.

In my MaxBee F2B model I use Igor Burgers "active" timer system, adjustments are made with a "Jeti box".
