I thought the H9 Pulse XT was an aerobatic plane.
With its flat bottom wing with dihedral, I'm not so sure.
Those who have one, do you consider it an aerobat or a sport flyer?

Thanks,

It is more a sport flyer. It does fly very well but is limited

Well it seems Horizon considers it a sport flyer, I just checked their website and nowhere do they use the term aerobat. Actually it the whole idea that an airplane has to fit into some rigid "classification" is pointless. Whether or not any airplane is 'aerobatic' is just a matter of the individuals perception that it is.

Its a low wing airplane a totally flat wing on a low wing ship would be terrible. Concerning aerobatics some of the very best of the low wing airplanes that I have flown (there has been my share of those) All used dihedral. Some of the very worst low wing airplanes that I have flown had a flat wing. Some of the very best high wing airplanes I have flown used considerable anhedral agine a flat wing is only half way there to that totally neutral roll stability.

So although I do not have one I do believe there will be just as many folks who 'perceive' it to be an aerobat as there are folks whose perception of it is as a 'sport flyer'. Heck I have been guilty of lumping the two together anyway.

It really depends on how you set up the airplane. Moving the CG back and increasing throws will make it very agile. Moving the CG forward and decreasing throws will make it docile.

The amount of dihedral used depends on the type of flying the design is intended to do. For a neutral airplane (no roll coupling with rudder), a low wing needs dihedral, and shoulder wing may be flat, and a high wing might require anhedral. If you remove the dihedral from a low wing design, you quite often end up with an airplane that rolls left when right rudder is used. This is known as adverse roll.

Most full size airplane are designed with some dihedral effect so that a low wing can be picked up with rudder. This is to give some redundancy to the controls, for instance you can fly the aircraft with just elevator trim incase the elevator gets disconnected from the control stick.

You can do aerobatics with it. You'll have some deficiencies in knife edge flight and your verticals probably won't be perfect, but there is no reason you can't do novice and sporstman class maneuvers from the SPA schedules with a Pulse.
