@Maddox - That does seem a hassle, and might not work as well, despite being lower cost. I may invest into a Vyper, or a Wotty, depending on what happens.
@Daveimi - I see your point, but the thing is I've done that, bought a couple feathers, and built, smashed and rebuilt more. McCheapo, Shazam, and the original version of McCheapo, what was to be called something else, never worked out, sadly. I could never get them to work, and hated them, to be honest. I'll try to get one feather actually working, although I was close to one, I just never got it going. I'll post updates on McCheapo, the Wonky Wheeled, Weaponless Wonder. As in, "I wonder how that even got into the arena?" I'll be wiring it up soonish, I have all the components.
