RE: Engine for 4 Star
Interesting.
Everybody has their favorites, and their own reasons for believing so, but as "popular" as the one-off motors would appear to be in this forum....I don't see it at the field.
We have a large-ish club in a part of the country where the flying season is pretty much all year. We also have a lot of very active flyers, and I find it curious how FEW of these "just-as-good-as" motors last more than a few outings before the constant twiddling, troubleshooting, deadsticks, damaged models and spoiled afternoons prove too much for the owners. Just that fast, a new OS or Saito is installed and the problems cease.
Maybe you are getting something for the extra $$. IMO...the field results I see speak loudly.
