I broke a few of the screws used to mount my engine mount on the chassis.....

Are those screws RC specific? or just generic screws?? I mean.. Can I just get them off Home Depot if they have the same size???

I have tried to find certain size screws at various stores. Never had much luck found some but not many. I order all of my screws in kits from www.fullforcerc.com. They are very good people with exceptional quality products.

Your not going to find rc screws at local stores I have tried so many different stores with no luck. Your going to have to get it from the manufacture or a website that sells them.

most common rc screw sizes will be either,
4-40 (standard) or,
3 x .5 (Metric)
Ace Hardware has a few to choose from, Lowes has a few more, like socket heads and flat heads.
Home Depot had about what Ace had. (at least where I go)
