Can you make a radio box? Any nitro tunnel can be easily converted by adding a box to hold the electronics Below is a Topspeed conversion designed so it can be changed back to nitro. A lot simpler box results when you cut into the tank hump. See the white Topspeed below.
Here is what I did with a Taboo. It can be put back to nitro just by changing the box,motor and fuel tank. (Never going to happen)https://photos.app.goo.gl/Vds1JpdM54LrDquG6
