I maidened it today.

The snow at the field was not plowed so I had to clear 8' x 30' patch for takeoff and landing. The flight was 5min short and never made the 2nd due to possible ignition module failure. In order to take off in 30' and not knowing anything about this plane, I gave full throttle and it did take off and just cleared snow.
More than anything, I wanted to see rock solid harrier with wide range of elevator positon but the plane did rock as much as other planes not known for good harrier.
Rolling harrier was surprizingly smooth. I manage to put in 1 inverted flat but did not experiment much. Hopefully I'll get the ignition module replaced by tomorrow for another flight.
In a new engine with slightly rich idle, it manage to hover below 1/4 throttle but it was difficult to hold from climbing as the stick was near idle and engine rough at idle. 2nd flight will tell more.

The plane came in at 13.25lb. For the purpose of getting DA50 plane under 13lb, slimline pitts will be replaced with stock DA muffler.

If I build one from scratch (no existing hardware or engine), I will go with zdz40re. I don't know if it is smooth running engine or not but that is another debate.
