Trust me it was pinned. To my knowledge the engine is tuned and actually runs very well. As for the grass it could probably use a trim but I didn't think it was excessively long. There are a handful of dandelion type weeds scattered throughout the runway...fun to watch get shredded but drastically reduce rpm when they meet the prop.

In the mean time I'm contemplating buying a low winged arf and fix the avistar when I get the time...sucks being "planeless"
