    So Wild,

    What's the span on this one and what are you going to power it with? If you have already said, my apologies..... it really!

    I think it came in at about 43 inches.

  8. Maiden voyage for the new PI Curtiss P-40 Warhawk. Built at 120% and now with a under cambered wing along with some flaps. Once I get a good calm day to trim it in I think it is a winner. :)

    That is the cats @$$! Looks great in the air.
    Nice.

  10. The under cambered wing was the trick plus I think at 120% it handles the wind a little better. Definitely way more stable at low speeds, I think I might really like having flaps. I have maybe only 3/8" deflection in them and it should does make it float.

    Jeff, Your a legend!
    The speed and quality of your builds are phenomenal:)
    That is a fantastic job you have made of the P.40. She looks to fly very well.
    You may be able to speed the rolls up with using the rudder with the ailerons ,but take it up high to see how she reacts. The roll you had looked about scale and the flaps add another dimension to the flying experience of the P.40.
    Well done:)

    Way to go Jeff, no muss, no fuss and best of all, no drilling, lol. I had a good feeling about it's success. Looking forward to seeing her dressed up with some paint and shark teeth!

    Jeff, Are you going to make a spinner on the 3D printer?
    You want a backplate to go between the prop and collet and then glue or make it a snap fit for the spinner.

    And while you're at it, maybe some exhaust outlets?
     
  15. I did print off a spinner already but I am not totally happy with the quality of it. It looks almost identical to the ones you were looking at tp buy for $2.95.

  16. Already printed, just waiting on a paint job. :D
     
  17. Thanks Ian,
    It flies remarkably well now , great call on the wing setup Ian. :) Once you are done and tested we just have to get Bimo some notes to update the plans. I like it. :)

    Oh, never thought of using the rudder also in a roll , I will wait to try that after I get some color on it for contrast I almost lost orientation a couple times. ;)

  18. No drilling was the good part. ;) I have to remember the flaps, on the 2nd landing I activated them 1 second before touch down and it just slowed down beautiful. Next time I'll activate them sooner.

    Becareful with them flaps Jeff they need to operate slowly to give you time to put in some down elevator.
    Any hint of tip stall now? I would imagine just a hint at slow speeds?

    Do you think a person without your cat-like reactions would enjoy flying it?
    It certainly looked a more relaxing plane to fly.
    When you get a spinner and some paint and a great big sharks gob on it, it will look fantastic.
    I might have to send mine to a paint shop to get a decent job done.
    I have been busy again with work today, but hopefully I can get mine finished over the weekend:)
    I am very pleased with this project so far. I just hope mine will be as good.
