RE: Bi-planes
Ditto! If you can't proficiently use rudder input in conjunction with aileron and elevator - you're not going to fly 3D! It takes constant input on ALL the sticks to make it happen sucessfully.
Bipes, for all practicle purposes, are some of the best 3D birds out there..........you just have to have one that's designed well and then it has to be set up properly. Without this you're basically screwed from the get go. Many folks take a perfectly good plane and do not take time to set it up to its optimal configuration and so you hear stuff like..........it's not a good plane......or this plane sux.......... when allot of times, it's not the plane but the pilot. Sure, there's some "junk" on the market but by and large, most of the planes available today are being refined to the point where they can function in many different venues while some are targeted for specific flying styles. Just make sure that the plane you're flying is intended for the style of flying that you want it to do.
The best way to learn all the tricks is to find someone >>>>that knows what they are doing<<<< to help you at first. Not only with the set up but also to help guide you in the different maneuvers. From then on it's practice, practice, pratice.........until you get it right or at least until you get it where you want it to be. Work on the areas where your flying skills are lacking and you'll find that in no time you will overcome your weaknesses. In other words, work on improving your skills first before taking on a plane that is way beyond your capabilities.
You'll find that every plane has its own flying characteristics and bipes are no different. Each one handles a little differently. You just have to get in tune with the way a plane flies and if your skills are up to speed..........you can fly just about anything out there. Bipes are one of the sweetest flying planes going!
