CP140 has a good point here,
when i was flying in germany some 15 years ago, you where required to register your
radio with the local radio regulation administration. The only available frequency band for airplanes was
35 MHz, cars & boats ran on 27 MHz and i can't remember what the 72 MHz was reserved to.
But i remember there where three MHz band catagories.
The us radio will transmit on the 72 MHz band, make sure you check with your club.

Also I think it is too much money you are willing to spend on a trainer with software.
Trust me, you'll get bored fast and want to move on to a more aerobatic plane within
a few weeks if you have some talent. than you are looking for a more expensive plane
and probably a new engine.
why don't you go to the local club, talk to the instructor and the other pilots.
There are always people who sell used equipment very cheap and will help you
get flying soon.
I was eyeing the nexstar, too when getting back into the hobby. watching the online videos was exciting
and the all included sounded nice ( didn't know you still need alot more stuff) I was almost ready to buy one.
instead, i emailed the local club president and he showed me around, introduced me to other pilots
and the next week i purchased a used pt-40 trainer ready to fly with engine and radio for $ 160.
The seller/instructor taught me how to fly and everything about safety rules, I flew it for 4 weeks and got bored with it.
I was glad i didn't pay much for it and had enough money left towards a second plane.
I still have that plane and currently use it to break in my larger engine that'll go in my contender.
Trainers just teach you how to fly and that's it. No need for sophisticated hard and software that
you will drop soon. the nexstar engine could be used in another plane but you are limited to the
40 size. a 60 size plane is much more fun and more visible.
My ultra stick 60 needed a saito 100.
good luck, pat
