I know heli''''s are much harder to fly than airplanes. Nevertheless, it would be a good idea to fly at least some sort of plane, even if its a park flyer, before taking a chance on crashing a nice airplane such as the one you speak of.

Pete:
Please heed Wing''s advice especially if you have not flown planes before.
While your heli experience means that orientation is not a huge issue for you, if you''ve not flown planes, your will not have the "muscle memory" for them.
Have someone give you a lesson or two with an instructor on a buddy box using a club trainer, so you do not have to purchase anything.
This will be time well spent.
If possible also have the instructor go over your new plane when finished, and take it up and trim it out for you.
