First flight of "White-Red" Hatz

[Woha]

Hi all,
After 3 years of building, thinking, designing and realizing my own concept of biplane, my White-Red Hatz departed for its maiden flight on 15th May 2017. The aircraft just flies like a dream, making my childhood’s dream come through.
By now I would like to thank you all for sharing your incredible experience and knowledge here on this great forum. I think it’s my turn now to share a bit info about my HC164:
ZFW: 548 kg (pretty heavy)
MTOW: 771 kg (approx 1700lbs)

Lights: Grimes with LEDs
Gauges: mostly Russian made: 3in1, CHT, EGT, ammeter, G-meter, clock
and AFR Innovate, MGL FF-1 w/Red Cube, low volt warning light from AS
Flight instruments: SI, VSI, Altimeter, compass, rpm, turn indicator

-bigger main wheels
-shorter MLG legs- 26”

So far the aircraft has 8 flight-hours and I still continue testing her in the air and on the ground.
At this stage I found one small leak from the fuel tank (investigating the source) and few things with my wonderful engine. I will try to write more about it later, after everything is fixed (I’m in touch with Rotec now).
Find few pictures below and link to the film. Enjoy.

Congratulations!!!

Lovely airplane! Thank you for sharing your experience , photos , and the data. I am looking forward to hearing about the engine issues, since my ship will have the Rotec as well!

I estimate my ship being 2-3 years from completion. Just finished the fuse basic structure and welding. Wings are done.

Oh, I forgot.....

What is the best average rate of climb for your plane?

Thanks!
