Guys, I picked up a Seagull Decathalon before Christmas. I will fit a 20cc petrol engine and have some questions about the ignition system. I have a 2650 mah 2s lipo for the Rx. Ordinary servos (not HV) so I have a Jeti regulator to go between to drop the voltage.
Should I fit a second battery for the ignition? Or would I fit a BEC to feed the ignition? I’m thinking my Rx battery is likely too small for both and two separate batteries might be best?
What about a kill switch for the ignition as a safety feature?
I know a lot of this is preference and 20cc is still relatively small, but interested in peoples experience.
Thanks. Kevin
