Zipties are great, no doubt about that. But my favourite is velcro, especially for mounting receivers and batteries. It kills the vibration, so you don't need any latex rubber around these components. Check the picture how neat that kind of installation comes out.
I got the rubber bands around the fuel tank in Extra with no problem at all (but it took a few minutes). I used it before and I like it, of course you can replace rubber with zipties.
Rubber is susceptible to UV light, which makes them "dry up and go away". Zipties have no problem with this, velcro either. But you need quite some velcro for for instance ST3250 in a quarter scale project - zipties are here my favourites too!
