      I think it's an interesting topic, and I made many runs without strakes, with great success. Now I will optimize the hull with the strakes, aiming for higher speeds and improved cornering!

    Wow, the ultimate iron man terminator ship. It's fast, strong, and fierce. If you don't break it right now, your belly will definitely go through the ground. I like it, it's fast, I'm satisfied, I'm happy with what I do with my hands, it's fun every day, thank you, thank you.

    The starkes are thumps up for me! I definetely like them! More scale look and better performance (at lest at the starights). I ll try them in my future projects!👍

      Thanks, Dim! I love them because they make the boat more lively. I will do some further experiments with the strake ends, as we discussed. Maybe these strakes are a tad too big as well. I guess a 4x4mm stringer would be a better choice, to enhance the cornering!

    hi, you have to lower their thickness, round them slightly on the quick part, leave them almost at a right angle towards the inside and soften the outside part, I don't know if I explained myself, maybe for that hull they are too wide, that square you used I think is 5mmx5mm, I used them for your 80cm drawing, good work!.

    • @CozyRC
      @CozyRC  Месяц назад

      Thanks for the advice! I agree, 4x4mm would have been better, probably. I will modify the ends with a smooth transition to the hull and also an inwards bend, looking to the bottom of the lifting strakes.

The chine over hang was almost the same depth from transom to bow and really helped with the spinning out in fast corners , So by adding new side panels and filling the hull gap, easy to make,

      The boat runs different, and more dry. I like the lively handling now, but the strakes need some work to improve the cornering a bit ✌️

    Great vid. 👍. I wonder what effect a 'stepped hull' would be. In theory, the air pockets create less drag & higher speeds. Regal (full size) power boats use them, successfully improving speed & efficiency... 🇬🇧

    • @CozyRC
      @CozyRC  Месяц назад

      Thanks, and the topic of steps in the hull is definitely interesting! I have a stepped catamaran, and it runs very efficient. I might try it on a mono as well, but I have too many projects and ideas for now 😅

    Maybe the lifting strakes should be on an angle? If i remember right i've read they had about 5' angle and maybe the lenght also has something to do with it. Not sure about any of these things but thought might be interesting if you wanted to test things.
    Its a funny boat, that's for sure.

    • @CozyRC
      @CozyRC  Месяц назад

      You might be right on the angle. I checked my Pursuit hull, and it does seem to have a slight angle for the strakes. The 5x5mm stringer size is also a bit too big. I should have gone for 4x4mm. Maybe I will... It's a fun boat for sure! 😎

    snelheids meting met flip nooit als betrouwbaar beschouwen.
    heb al een paar keer gehad dat ik een meting van 120+ heb gehad bij een boot die net aan de 100 haalde keer op keer , op 3 keer na alleen in die runs flipte ook de boot.

    • @CozyRC
      @CozyRC  Месяц назад +3

      Yes, je hebt gelijk. Ik heb vaak genoeg met deze boot gevaren (met gps) dat ik weet dat deze snelheid plausibel is. Maar voor een officiële meting telt deze niet idd

      je kan eventueel de stakes nog wat korter maken om het bochtgedag te verbeteren.
      zie je vaak bij de wedstrijd boten ook dat de stakes een stuk korter gemaakt worden.

    I just watch again the run without strakes and :
    2.2A lipo 61 kmh
    3A lipo 63 kmh
    Now with strakes
    2.2A lipo 67 kmh
    3A lipo 72 kmh
    Yes the boat run faster to bad that she don't turn like before but you will improve that
    Same prop?

    • @CozyRC
      @CozyRC  Месяц назад

      You're almost right. The 61km/h and 63km/h were both with a 2.2Ah lipo. And the top speed with the 3.0Ah lipo was 72km/h. All with the same 936 prop.
      The fastest prop so far, is the 436 TFL 3-blade prop. I will try more props in the future, and I will improve the strakes as you suggested me 👍😎
