Zyprexa | KFm3

A new project, a different plane, a new airfoil (KFm3) a scratchbuilt without plans ,  I named it  after a medicine that can give you a floaty feeling.
The KFm3 airfoil is an easy and fast built and should provide the Zyprexa more lift then a flat piece of foam. Also I wanted to experiment with more KF airfoils as I had used KFm2 & KFm4  before. Making a body was more challenging as I thought. First I made a full body but that was way to heavy for what I head in mind. It had to be a flat out. I was inspired by a Fox which I saw on HobbyKing and gave it an other shot.
Span 120cm | Length 80cm | Cord 16cm | Tips 8cm | 1400KV | 10A | GWS 7035

    Hello Mr. HBFP NL!

    My name is Gyorgy Varnagy and I live in Budapest, Hungary.
    I would like to ask from you the next.
    Can you give me the proportions of the Zyprexa?
    I have already built the STC and STS trainer planes and I’d like to build faster and bigger plane. I like this plane very much and I’d like to build it if you agree to it.
    Looking forward to hearing from you

      Hello Gyorgy,
      Thank you very much for visiting my website!
      I searched for my Zyprexa data sheet and used plan and could not find it 😦
      However I think the most you can design your self by using the data on the website.
      If I would make a new Zyprexa I would increase the aileron surfaces to get better control.
      The wing is quite easy and the fuselage you can design yourself of coarse. Make a nice one yourself is always fun to do.
      The KFm3 is applied on the normal KFm3 way.
      Enjoy scratch building!
      Happy Flying,

    Hello Eric!
    Thank you for your reply.
    I’ll try to build this Zyprexa on the basis of your websites’ pictures and data and I try to take your advice (increase the aileron surfaces).
    Thank you for all your trouble.
