I'm looking at my new issue of Model Aviation and in a Brison ad , they announce the addition of "Automatic Timing Advance" to the 2.4 engine. It states the improvement will eliminate the need of 20 moving parts and will greatly improve the reliability and longevity of the engine. Is this the same thing as Syncro Spark? Anybody have any experience with this new mod? Just wondering as they have also raised the price on the 2.4. Since they eliminated 20 moving parts, is it lighter?
