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.

Put on some sealer on the fabric....if you don't you will see EVERY fingerprint and exhaust residue from now until you bury it!

I have not found any information out about the sealer. I have been told not to use Scotch Guard, it turns yellow. Does anyone know what to use? I need to clean the airplane before it is sealed can I just use Windex?

I am not sure what size spinner to use for this plane! I have looked thought the manual and I didn't find anything. The cowl measures roughly 2 3/4" between the cooling vents on either side of the shaft hole up front. That seems like it would be too small of a spinner. Would a spinner nut be more appropriate/scale?
