i have noticed that companys are starting to make conversion kits for 1/8 scale buggys and some other vehicles.

for those of us that want to put brushless into a nitro that doesnt have a kit available what should we do? i have seen a few homemade mounts and battery trays but are there any good ready made motor mounts that are universal and could be modified to work in other applications?

Most people just fabricate a custom motor mount and strap a battery in somewhere, works fine. Just buy a slab of aluminum and machine it into what you want.
