ORIGINAL: Nitro Napalm

Yup i broke it I don't know why but i'm kind of proud i can now say i'm a true basher - it's done no more than 20 tanks and iv'e broke an a-arm...the top left one to be precise - tried super glue but the stuff don't stick because its in a awkward position. I'm going to have to buy new ones. Any ideas where from - i got a stock HPI RS4 MT2... I got to get it now so is there a cheap alternative such as you can just buy the one thats broken? or is that you have to buy the lot? i wouldn't mind just the stock plastic one but if it's near enough the same price as an aluminum one ill get the aluminum one. But will it fit - the all one? Anyways please answer these questions PLEASE I think god did this [&o] I think he wants me to get down to studys [] lol so please help...thanks in advance (P.S. i broke it by going 30mph straight in to a pole...LOL!)
