RE: Contra Rotating Propeller Drive for f3a 2m Pattern Planes
I saw one of Andrew Jesky's Sparks last weekend, and the spinner on that plane was way too small to fit a Contra Drive into it. However, I've been toild that there is a new Spark coming that has a much larger spinner size. Are these dimensions for this new Spark, or the old Spark. If they are for the new Spar, then we are still out of luck.
