RE: New Plane??
All trainers fly pretty much the same.
The Hanger 9 Arrow RTF, because of the semi symetrical airfoil, is going to land faster than a similar trainer with a flat bottom airfoil. Remember, you are learning HOW TO FLY. When learning, slowness and stability are definite pluses. If you purchase a trainer with a flat bottom airfoil, once you learn how to fly, you can modify the wing to remove the dihedrahl. A flat bottom airfoil with no dihedrahl will provide ALMOST as much fun aerobatically as a semi symetrical airfoil.
The primary issue is the radio equipment. You need to find out which brand the MAJORITY of the people in your area are using. I would then suggest that brand. While you are at it, find out which channels are the LEAST USED at the field you will be flying at. Get a radio on one of the least used channels. It will maximize your time in the air and minimize your chances of accidently being "shot down".
Some things to keep in mind about RTF packages.
1. Substitutions are almost never allowed.
2. The engine provided, while fine for a trainer is usually marginal in power for a second plane.
3. The radio provided is usually a BASE LEVEL radio.
Some things to consider.
1. Buy a trainer ARF you like (from recommendations, appearance, etc.)
2. Buy a decent ball bearing 46 engine (Thunder Tiger Pro, OS FX/AX series, possibly GMS) Stay away from the OS LA series and do a search on MDS engines and then form you own conclusion about them. The brands I mentioned are user friendly, and normally run right out of the box. GMS is the least expensive (but requires a little more "fiddling" ), Thunder Tiger is the next expensive, with the OS as the most expensive. The price difference between the least and most expensive is about $40. The ball bearing engines will provide about twice the power of a bushed engine. The ball bearing engines will have plenty of power and performance for a second, third and later planes.
3. Get a 6 channel (or more) COMPUTER radio. You will be using the features of the radio within a short time and you will not "outgrow" it within a season or two.
Yes, this will cost you more initially than a RTF package, however, you will have a radio and engine that is highly useable in other planes without having to go and buy then "again".
This is my personal opinion.
I hope it has been of some help.
