I am picking up a New Hanger 9 Super Cub tomorrow for my wife.
It has a New Ryobi 31cc engine for power right now.
I am curios if anyone has any tips, or ideas for us to get it ready for flight.
It has Futaba 3004’s all the way around. I was told that the manual recommended these but I am sure JR servos were actually recommended. Will these servos be enough?

I also need to find a Spinner / or prop nut. The Ryobi will spin a 18” – 20” prop so I am not sure what size spinner to use.
This will be our first Gas engine for RC. Is there anything to expect, or watch out for?

We are also considering a Futaba 7C radio for her. I can’t see any advantage with the 6E or 9C that this radio doesn’t already have.
