https://youtu.be/3CQpTPuFdeQ in the video description you have all the information to get the planes and the full version download link
names for planes, rename the following items with one of those names to get your plane
firework rockets: p51 mig19 f86 f35 f22 me262 p51x2 f100ss aim-sidewinder mig21 meteor fokker vaso f16 helicoptero a10 f16b bf109 f104 a6m-zero stukaju87 f15 f4 harrier
totem of undying: cessna
bow: mp18 m1918 aks74u
egg: 30mm agm65
splash potion: gbu 12


mules are motorbikes, more specificaly the crf 450, the old model (honda titan 150) is included in the files and if you know how to edit the texture pack you can add it but the crf 450 is the default motorbike, there is also an experimental replace for horses, a yamaha yfz 450 quadbike


pd: some planes aren´t finished yet so if you see a plane with texture bugs don´t worry, it´ll be fixed soon. you just have to hold the renamed firework rocket while flying with the elytra, you can also put the renamed rocket in an item frame to have the plane on the floor
