O.F 25 F
I recently bought a bunch of RC parts from a guy who was selling out and found a brand new in the box O.S. 25F ABC. I was wondering about the type of fuel to use and how it would compare power wise to the modern 25s'. The only instructions that I have with it are for the 2b, 2ca,2cb,2cb-d,etc. "automatic carburettors"
