The carcass of my Dads RD4 has a different fan than my other 4G D4. 6 blades that are narrow. Was that standard on the RDs or an option or somebodies piece from some other machine ? Grant.

Almost forgot to share the RD4 I got for free. It had been sitting on the sidewalk of a commercial area of downtown San Jose, CA for many years. The machine is surprisingly complete and hardly vandalized. My first crawler that came with graffiti.

I believe the early ones had the thinner blades
