Setup questions 75" 3dhs edge

I have one of the newer 75" edge 540's from 3dhs. Im trying build up my skillset in 3d. Heres my setup
Xpower 30cc, xoar 20x8, castle 90, running 12s 3300mah.
Im having trouble hovering. I can do it fine in the sim and with my smaller planes. When i pull to a hover i cant hit that sweet spot if i add throttle it climbs if i back off a slight bit it falls. Should i try different prop if so bigger? More /less pitch? Someone suggested running a throttle curve. Right now im getting fantastic efficiency from the setup 6 min flight is only pulling 2000mah out of the batteries so dont want to lose that if i can help it but feels like it should hang there within a wider range of rpm.

Is your throttle got the ratchet still engaged? Most guys disable that, you might be needing to hit right in the middle of the ratchet, very easy to do this yourself. OR, hovering on the simulator and on a real plane is different, might just need to keep practicing

There is a lot of factors here.. that’s tough to give advice on but I would start with a soft throttle curve..

Did get some improvement with throttle curve softening up the bottom end of the throttle. And yeah i need lots more practice just trying to figure out if my setup is holding me back. I can hover my 61" extra ok but it has a aura8 in it. Trying to putt around in high stall angles gives the same problem it either wants to fly out of the stall or drop a wing. What do you guys do when performing these maneuvers with an electric plane. All my giantscale experience is years ago with big gassers. Do you blip the throttle or find the sweet spot and hold it there?

I probably could fly your edge see where I can get it steadily throttle hover like I did on 92 Edge and so incredibly stable I ever flew than the 104 extra.

Practice is what's needed. The throttle I just vary a little too keep me in place. How's the CG feel? Sounds like you could still be nose heavy also

Throttle curve adjustment did help a bit as for cg she flys a perfect 45 inverted upline and holds it with no elevator input. I can move batts only afew mm further rearward before hitting the wingtube.

Proper CG helps all around... I started mine with the fwd "Safe" location and it flew nice but was a 3D mutt... as I move the CG aft... it just gets sweeter and sweeter!!

Ill try shifting it back a little tomorrow might have to use a larger rx battery to get more weight behind the wing tube.

Moved batts back to the wing tube made it a little better but still struggles to keep the tail down. May try a bigger rx batt behind the wingtube.

I tend to get in a hover and then blip the throttle a little. When I blip it I have to counter with aileron because it torque rolls a bit when I give it throttle. I tend to be able to lock in better with this method. Just takes a lot of practice and every airframe reacts a little different.

Blipping IMO is a great technique with gassers, but I find it a lot less useful with electrics. I try to keep comparatively steady throttles when hovering electric... for me, blipping is one less thing to think about.

Everyone is going to develop their own technique and style.
Get as much stick time as possible, and as said above. practice. Spend 2-3 minutes of each flight practicing your hover, and you will fast get real comfortable

Swapped out the 19x10 xoar for a 20x8 falcon much better now pulls smooth to a hover and is much easier to manage. Slows down for landing much better as well with the bigger prop disk.
