RE: aerobird V tail or rudder/elevators?
Here is some info you are looking for: As far as the wind, they handle about the same. Flying these small craft in wind almost always comes down to one thing, pilot experience. Both airplanes are going to get knocked around in winds that go over 10 mph, however I can manage wind much better know that I am a more experience pilot.
Two, if you want the slow stick to be able to fly far and high you will need at least two things, Once is a good radio system and the other is li-po batteries. A good transmitter and a double conversion reciever will give enough range to make the SS look like a red dot in the sky. Li-po batteries will give the plane the endurance to fly far and high.
Third, I have never heard of HobbyZone installing brushless motors in one of their planes. I have never heard of it as an aftermarket hop up either, but I could be wrong. This would push the price of these RTF craft very high. However, I have seen brushless setups on slow sticks and they turn the SS into a sort of 3D plane. They even hover. Granted, the back mounted propeller will withstand more crashes, but I have broken my fair share of GWS props and they are simple and cheap to replace.
Last, because most people use a 72 megahertz radio system and micro servos, they just transplant them into other GWS airplanes. I took the electronic system from my GWS P-51 (which is a stupid first plane) and put it into a GWS Pico cub. After I learned to fly that, I put the same system into a GWS E-starter. I have other planes now with other electronic setups, but the E-starter still flys and I still get a kick out of it.
Remember that a SS only uses rudder, elevator and throttle. However, many pilots easily convert the SS into an aileron plane. This will increase the aerobatic performance. You cannot do this with a Aerobird Challenger.
