Anyone have a spare 20FP w/muffler they would consider parting with? Planning to build a killer Flight Streak. TIA!
Paul, maybe you're aware, maybe not.
On the OS FP series engines, OS upgraded the design at some point from iron/steel piston/liner to ABN design but never changed the FP designation. So, you might want to clarify which version you want. It's easy to tell. The older iron/steel version has a bump on the side of the case.
I don't own a 20 FP, but I have run the FP newer ABN design. They are very similar to the LA series in how they operate.
As claimed by OS, the 20 FP (ABN) weighs 7 oz (engine itself). The iron/steel version a bit lighter at 6.8 oz. I believe they use the same muffler.
