Probably why my fuesalages always turn out crooked🤣(jk) the strongest it’s stocked with is Dr Pepper🤣 it’s mainly used for storing all those fresh eggs😁
Cut the foam the same way you would fb (wing edge 90 degree cut and control surface edge 45 degree cut) and I use a full long strip of blenderm tape on the top side and short strips spaced and inch or two apart on the bottom side. Before that I also will do a small bead of UHU Por (Beacons Foam Tac) along the edge of the hinge line and let that get really tacky and then put the two pieces together, you should have a working control surface without the tape but do use tape and you can use really any tape that adheres good to foam.

Before you give up on the motor, might be worth trying a prop with more pitch? Cheaper than changing the motor and might do the trick if you can find something suitable. Increasing pitch will have a similar effect to increasing motor kv. Good luck!
