I was able to get 2 flights in, I spent a good deal of time at the field programming the fail safe and then doing a range test, since it was also the maiden flight for the new transmitter. I was worried/nervous, and to break the nerves, I started the day putting in 3 flights with my Extreme Flight 91" Extra with a DA 85, and then I moved up to my Dalton Yak, and put two flights in her, practicing the 2017 Advanced sequence on all flights. After that, I told Stacey, "I AM READY< LEt's DO this!!!"

It was a complete success..

Upon take applying 1/2 throttle, airplane took off with low AOA without me giving it elevator. Once i turned it coming back, i noticed it wanted to climb, gave it two clicks of down elevator and it was flying level. Did not have to give any rudder or aileron trim (first time I build an airplane and did not require aileron trim)!

Additionally, once it was flying level, I did take my hands off the transmitter for a good 10 seconds to demonstrate to the peanut gallery how it tracks (Just phenomenal, I have never flown an airplane that tracks this good!)

This airplane cuts thru the wind! Just phenomenal!

Ok, after 1st flight, took maybe 4 minutes or so), after landing her, I moved the batteries back 3 inches as I felt it was ever so slightly nose heavy, then I inspected that all the screws on the linkages were still there, and no surface was loose.

Then took her off again. (there is a video somewhere of this), and then I did the inverted 45 degree climb, and it was ever so slightly coming towards the canopy) and, when flying inverted, I have to give just a tiny bit of push.

Spin Entry = Phenomenal!! Looks like it completely stops forward movement, and then nose and one wing drop. Very Very nice spin entry (stall), (this also tells me my CG is good).

Knife edge flight, no pitch coupling, but there is a very slight roll coupling.

Up-lines, maybe a tiny bit of going positive, but I will test this more, but it was not pulling to left or right. Pretty darn straight on that.

Downlines, I will need to add a downline mix, it has a very minimal amount of pulling out.

The mixes I will add will be all maybe 1 to 2% to make it fly "perfect" as they say!

Coming in for the two landings, I was surprised it slows down plenty to land.

I really like this airplane, and to date, I had never flown a Carden, and I had never flown an Airplane that flies this good. Primo was right!!!

That is always satisfying after a long build and bib everything to the best of your abilities and researched everything to get it right. Then test fly it and it works just as you had hoped for very satisfying. Hope you enjoy the plane and it competes well for you.

Love the graphics that just makes me want to buy a Jeti that must be good to have.
Question trying to understand the signal strength grafts. Please just bear with me. At 100% does that mean the receiver received 100 % of the info from the radio. So at 50% what did you lose. You got 50% less of what and what does it impact. (Only distance does that mean you have lost half the operating distances?...). Ok at what % loss are you at risk of losing the plane.

Love the height graphics are you surprised at height you are flying at it looks like you averaging 500 ft that is a surprise to me or am I reading the graph wrong. I do like it.

Well congratulations on the Maiden flights , all went well and came back in one whole piece .

Do like the graphs with telemetry especial being in colour and from your new DS24 Jeti .Wow though you would have got that radio in the fall .
I know it's cooler now than summer but how high would your engine cylinder temps peak at before your alarm comes on ?

Nice to see your enjoying all the fruits from your labours

I just cannot stop looking at the graphs. Looking at your temperature and RPM graphs it looks like your temps are going up when your rpm props or the the two graphs not quite lining up. Would be interesting to see the a long sustained run and then look at the temperature correlation.
