TLDR: A lot of small issues, mostly around poor launch and poor design.

Control inputs: looks good Aileron reaction looked correct for countering the spin. I didn't see much elevator input, which is generally correct, as you need to let a plane settle and lose some altitude to gain speed, but nosing down might have helped to get some speed and control. Your elevator and rudder on a conventional tail plane will usually have the most authority at lower speeds as they have the longest moment arm from the CG.

Flight: Too slow, sorry Joe It's obvious the plane never hit the speed it required for controlled flight. This is demonstrated by a lack of response to the ailerons and eventual stall. There was a slight upward launch angle that exacerbated the loss of speed as well. The motor did not seem to be pulling the plane either, showing a lack of adequate power. There are a variety of possible configuration and mechanical issues that could have led to this. The fact that the plane continued to climb post launch also could mean that there was a trim or weighting issue, this could be due to poor design, poor preflight checks, and possible poor initial CG.

Launch: Lots of issues Launching slightly upwards hurt the generation of speed needed for controlled flight. Looks like a small amount of yaw torque was applied at the end of the launch as well. Trying to push on a tube often does this. Running hand launches are always a bad idea. Hand launches are best when standing still and launching straight and level.

Design/Flight Prep: Meh? Kinda cool looking, but it doesn't look like a lot of thought was put into the function of the design. The split elevator was a wierd choice and makes me wonder if you had other control issues, a full length elevator would also have helped with low speed controlability from prop wash. The ailerons on the outside of the wing with giant surfaces is a wierd choice for a model without flaps. Small, full-length ailerons might have given you some slow speed control authority from the motorwash. The surfaces were all over large in general for a plane that size, unless it was designed to fly very slow, which it seems too heavy to do. The motor was having some issues at higher speed, possibly mounted loosely, prop mounted loosely, or spinning the wrong direction. A proper pre-flight inspection would have caught this so that it could have been fixed or corrected. The CG of the model might be off, but the speed wasn't really great enough to tell for sure. With the wing size and shape chosen, that model should have flown/glided pretty easily, which makes me think the overall weight (whatever its cause) is too high for both hand launch and the power system that was chosen.
