I have been flying rc planes for a few years and I have a .60 size 540 edge that I have had since 05. It is running a OS .61 2 stroke. I have played around with inverted flight, knife edges etc. I have not mastered knife edges nor hovering. Do I need a more powerful engine to accomplish these manuevers? Also what control surfaces need to be executed in order to do this...i.e. full left or right rudder for knife edges correct and compensates some elevator?
Thanks

If it were me, I'd keep that airframe for after you learn.
Profiles fly the best, and are easy builds and easy to repair.
One of the best is a MoJo or ProYak.
You won't get better advice than over at:

First, start with a good setup. You need enough power to go straight up out of a hover.
Make sure the CG is correct by flipping inverted and it should take no elevator to maintain level flight at about 2/3 throttle.
You'll need throws as much as you can get on that airframe. No mixes, no low rates.
You need to get used to the throws, they are how you get out of trouble. Nose up and full throttle to escape.
Knife edge is nearly impossible till the setup is correct.

Start with the basic building block, the harrier. Most 3D maneuvers start from or going into harrier.
This is all about throttle management and keeping the nose high in stalled flight.
After hours of feeling comfortable in this attitude and doing figure 8's while in harrier, then move on to other stuff.
Seriously, don't move on till you get this.

Hovering is nothing more than an extreme harrier with the nose straight up.

The next step is inverted harrier. Most airframes, set up properly, harrier better inverted than upright.
You will need to get used to the control reversal on the rudder and elevator.
This also takes time (gallons) to learn and when you start to get it then move on to inverted figure 8 harriers.

Everything else 3D will be very easy and come naturally when you get this harrier stuff down.

Morgan do you have the link of the airplane? so we can comment more?.

Practicing on a sim first may help. It will teach you what to do and how to react when you get into trouble. I practiced for a long time on the sim before I even touched a 3D capable plane. And before I tried the hover for real, I hovered a whole day on the sim. Of course the sim can only teach you so much

Here is the kind of plane that I have. Clor scheme is a little different but the same overall. I have had it since early 05.

You need to have a minimum of a 120 two stroke with that much weight in order to hover comfortably. I read 8.4 to 8.8 lbs on your link page and that's pretty heavy for 753 squares on the wing. A 9 lb plane needs 950-975 squares to be light on the wing and that makes for a good 3D machine. It'll fly with a 61 but it ain't gonna 3D with it; just not enough grunt. A Swannyshouse MoJo would be a great plane to learn 3D on as TS mentioned.

Thumbskull's advice is very good as is ameyam's advice about the sim. It's very cheap to hit the little red button and get a new plane LOL.

Thanks all. I appreciate all the help.
