Maybe a stupid question but does anyone know if the RB5 body fits at all on the RB6?

It does not fit as the rb6 had a much narrower chassis and is longer.

I am currently running 78/22 on my Orion 8.5/r10 pro combo. It was slow and way undergeared do I added some boost and +3 degrees on the endbell and it is rocket fast and came of at 99 degrees after a six minute main.

I see alot of people using a 69T spur on their RB5 for 17.5,I don't see a 69T Kyosho gear anywhere. What spur gear are they using?

They are using Kimbrough gears for an Associated. You will need the slipper pads as well. Most locals here are running the 72 spur with a 32 pinion in stock blinky 17.5
