I have never had my side x side packs fly out, even in brutal crashs where everything stayed where it was supposed to be. As for the foam tire thing on the side that seems interesting but I think it may still over power out the side. I have a TC3 coming in so I am going to gut it for the TC2 Cylcone and probably the hexes and foam spacer. Has anyone tried the velcro around the strap method? Who sells the cheapest aluminum hold down strap?
as for the capacitor, I may just mount it with some servo tape to the spur gear cover right before the button hold down screws. Or, that mounting to the wires looks pretty trick.
