Default 30% TOC wont hover.

I know when you first looked at the thread heading you thought another newbie with not enough practice. Well this is deff the plane.

Plane 30% TOC yak 54
Engine DLE-55
Servo's hitech 7985's all around 7965 throttle and JR 8711 rudder
Prop Vess 23A
Weight dry is 17 1/2 pounds Full 18 1/4

CG is set just a little to the back. Another words in inverted 45 it climbs slightly.

Surfaces Elev endpoints at 45* Ail 40* Rudder 40*
TX high rates Expo at 80

Modes I've already done.

Mounted the fuel tank 24 oz. under the wing tube in the canister tunnel.

Ok I have a few mixes for knife edge both ways clean and stable. All summer I've been fighting this plane in a hover. Today I let two of the hover veterans fly it and low and behold they could not get it to hover either. ( and these guys are the best I've ever seen at hover)

Problem The plane is very unstable at any latitude and throttle position. As long as it is climbing slightly then it locks in but as soon as you lower it to drop the plane or hold it on one postition it leans to the wheels. At least 3/4 on the elevator to hold it for half second then pump on the elev to correct. We pitched it back and it holds a second then falls out.

I oraganally set up the plane for IMAC but it will soon be replaced with a larger plane so I thought set this one up for 3D and freestyle and huck it. That said I had to add 5 ounce of weight to the nose to get it to balance at CG stated above. It flies IMAC on rails right thrust is just a little out so I need to give it a little on upline entry. Anyway everything in the kit is stock Alum LG, wing a stab tubes.

Any ideas?? Some think it is a thrust issue another said to take out the 5 ounce of weight. I can fix a thrust issue but would like to keep the CG where it is in case I need a IMAC back up.
