When do you think the OS FP40 went out of production?
When do you think the OS LA40 went out of production?
I don't know for sure.
I would guess that the last FP was made at least 30 years ago and maybe 10 years ago for the LA. Personally, I have a well supply of FP 35's and 40's. But at the Brodak Fly In I will permit the LA 40 in the interest of participation. If anybody does use the LA 40, I will note that fact in the report to NCS. They are free to reject the score from the annual standings. Having used both engines, as well as the FP & LA 15's and 25's, I am convinced that the FP was a better series. For an event to survive it needs to consider the equipment available to potential contestants.
