    Hi Sergio,
    Thank you for accepting my invitation. i appreciate the time you took to detailed the advantages vs disadvantages. I now understand why most people do not tackle a fiberglass cowling -:)
    I have to say your plane look fantastic, you did a great job. i can't wait to have mine at the same stage as yours.
    I'm still on the tail section of my CH750 but at least I'm progressing hahaha!

    You have a very clean engine install, is the HP of that rotax enough for STOL?
    I'm thinking of using a Rotax 912 because I will most probably be on floats.

    have fun flying your plane safely!!

    Hi Sergio,
    That's very informative as i have very little experience in engines in general.
    I will certainly take a look at the Hirth engine, its sounds interesting.
    I have seen some of them here in Canada on Challenger II ultralights.
    i will look for a distributor for those engines here in canada.
    Thank you very much for the information and I'll keep in touch.

    Hello Sergio, it's good to hear from you again. The increase in power is do to increased compression and advancing the cam timing 4 degrees. The fins just allow me to utilize the power continuously and keep the heads cool enough to prevent damage. I flew it the other day and it was over 80 degrees F. on takeoff. I climbed at full power all the way to 2500', a 2000' climb and the heads never got over 320 F. I couldn't do anything to increase power before since I couldn't maintain full power as it was. I'm already planning another more powerful engine ! Wayne
