Talk about getting off subject here, Shheeeeeesh.
Scott, you're doing a great job with the building and I can't wait to see it fly.
As far as the 140 claim. That would be mine !! Yes it was on a down wind run coming at Pylon#2 with a 15 to 18 MPH tail wind.
The engine is a VERYold and tired TT40 with the stock muffler and a new style carb. that doesnt turn alot of ground RPMbut seems to unload very well. In fact the engine hasNo pinch and "free wheels" when you are landing. I need a new piston and liner.
Ihave probably 80+ flights on Stinger and its a ton of fun,
