I went ahead and super glued them, holding fine. The things fast all I have done is ran it back and forth in a parking lot. It's hard to control, its a used chassis so I guess I need to overhaul it. Anothe thing is that the stick packs I'm using are getting so hot there melting the plastic on them, not sure if it's effecting the cells themselves yet, I havent opened one up. I plan on gettng some lipos but shouldn't 6cell NiMH hold up.
