Do yourself a favor and save the Catalina until you have more experience with RC flight.

Find a local club and attend one of the meetings to find out about their airfield and training programs.
Do not try to fly the Catalina as your first plane. While it is a nice flyer, all planes need trimming out in flight, checking, and setup which novices do not understand.
Most novices have to contend with out of trim planes, that are not correctly set up ( by them ), on their first flight.
This guarantees a disaster, and the lifetime of their first planes are measured in under 20 seconds.
You'll find very experienced flyers at a club who can go over your plane, spot and correct any problems, take it up for you and trim it out, then help you through your first flights.
Clubs WANT you to succeed and not waste your money with crashes.
The AMA webs site has a ''club locator'' for you. Check it out.
AMEN on this one, save it a get a trainer and 50 or more flights under your belt..!!!
