Yes, there are a lot of electronic launchers. This may or may not compare to them, but it's only Mark III XD. Mark I didn't include the Light Launcher Casing. Mark II added the casing, with more tape. Mark III takes away some tape and adds string. Mark IIII makes the unit that powers the launcher is made more compact. Sadly I didn't take any or much videos of Marks I-III, and if I did, they suck. But I will make a video of Mark IIII and upload it to my youtube channel. Check back in a couple of days, or maybe even today, as I will upload a video of Mark IV. Oh, and yes. This thing HAS gone through too much changes. But I think this is the farthest it can get. The only way to make a Mach V is to add more power...but that's kinda hard for me. Check back soon!
