RE: How to hover?
Ihave found that if the plane cannot elevator drop, then you definitley do not want to be trying to learn to Hover with it. Believe me, I have tried so many different planes, as I currently own over 100, that there is no since hovering a plane or learning to hover with a non 3D plane. However, once you learn to hover, you can amazingly hover many planes you would never imagine could, for instance, I can hover the Eflite Taylorcraft plane.
The planes that do the best 3D are those that are nearly or exactly the same in Wingspan and Length. If your plane is much longer in length than wingspan, then you've got a pattern ship. Excluding those planes that are obviously not pattern or 3D.
One of the planes I learned on was the Eflite Eratix. Electric. Lots of wingarea, tons of rudder of elevator surface. A great plane to learn 3D on. Then there is the Addiction X. Or Extreme Flight Edge 540t electric. and many others. But yes, picking the right plane to learn with is very important. You'll kill yourself trying to learn to 3D or hover with the wrong plane, and/or a bad setup on the plane. Even a throttle curve on electrics plays a big difference in performance.
If you have someone at your club that already does 3D, knows how to setup the mixes, etc, have that person test your plane. That way that person can tell you if the plane is wrong, the setup is wrong, or if the plane is right on, and they show you all what it can do. At least you know the plane CAN do the 3D moves, and its now all up to you to learn to control it.
Hope some of this helps.
