Is my plane OK for 3 D

[TeddyTyler]

I have a lainer funfly kit , its said to be acrobatic, but it alerons arent huge, will it hover? with a 46 BB and 12x4 prop and also the alerons should I make them largerhttp://file:///C:/My%20Documents/funfly.art

Sticks are good sport flyers, but they aren't 3-D.
You could hover it with enough motor and proper CG, but that aint 3D either. A trainer, with enough motor and rudder will hover.
You need something with thick chord, thick airfoil, huge rudder, lots of motor and barn door control surfaces(all of them). Use longest prop with lowest pitch possible for the motor you're using and try to work the CG back as far as your skills allow. Then you'll have a 3D ship.
Good luck,
Trashman

Thanks for the info say what is the definition of actual 3D flying, and like you said a trainer can make the moves of some 3D stunts, like what would be the difference between a trainer hovering real nice and a read 3D plane hovering real nice?

Teddy,

A 3D capable airplane is able to perform the aerobatics at basically a "stalled wing" state. That is the wing is stalled and not flying. You are using the thrust of the motor to create lift. They are not designed to fly "fast". They are designed to go immediately where you point them and stay there until you tell them otherwise.

A trainer is designed for just that.....training. No trainer is designed for aerobatic flight. They are designed for "stability" and not for aerobatics. And as a result they suffer from their "stability" in the aerobatic spectrum. Bottom line......A trainer does not like to do aerobatics.

Having said that, any airplane with large enough control surfaces and enough power is "3D capable". But, there are planes that do it better than others. To use your example. A trainer with enough thrust and enough control throw will hover. But, I would much rather be doing that manuver with a Knife than a Trainer. The Knife is much more capable of 3D flight that the Trainer. Kind of like comparring a Walmart bicycle to a 2004 Lexus. Both will make a 1000 mile journey, but there really is no comparrison!
