June 2024 After Crash Test run Magnum XL 1.20 4 stroke Glow Engine

Engine came out of my Phoenix Model 1.20 size RC Sbach 342 after it recently crashed from control loss.
Prop: Master Airscrew K series 15x8
Glow Plug: OS Type F
Fuel: Homemade 15% model plane glow fuel from a particular Individual
After I ended this video, my dad explained to me that the full throttle sluggish behavior towards the end of video is probably from not having enough fuel to sit high enough in the tank for more efficient fuel flow. The tank looked 25-30% filled at that time of the video.
