This is more an observation I want to bring to your attention, rather than a question. Your web site technical data page lists the Shoestring ARF as requiring 2 degrees right thrust and 2.5 degrees downthrust. Observations of two models by two different people have come up with identical conclusions: that while there is clearly right thrust built into the firewall, there is no downthrust (i.e. the firewall is perpendicular to the datum line). There is no mention of thrust line settings in the manual, but I and others here have noted that the plane assembled as is (without thrust line adjustments) generally requires a lot of down trim for normal flight. You might want to check into this for future runs, or at least mention the need in the manual.

Thanks, we'll pass that on to the Product Manager.

I goofed in my previous post. The GP web site technical data calls for 2.5 degress RIGHT, and 2 degrees DOWN, not vice-versa, as I wrote before. Sorry about that.
