    I am amazed at the flight time, my 600 used to get 12 min with low head speed and two 5000mah batts running parallel, but it was no 800 lol, god she is pretty!

    Thanks for all your comments, I'm surprised at how many views this has had as its just a boring vid of me hovering, I thought most people would only be interested in hardcore 3D.
    I love to see these big heli's in a stable hover but a lot of people think there is no skill in that.

      funny even at 1000rpm that thing will still kill you I mean a toy helicopter is a toy but a big boys machine that even at 1000rpm ile still be scared bigger blades have more inertia. than 700mm blades at 2000rpm

    Thanks for the reply, I love to see these big heli's in a stable hover. My only interest is scale flying so have no interest in 3D.
    Started this hobby back in January this year with a Honey Bee V2 FP and have worked my way up to the 800 building all the birds myself.

    I'm currently building a 700 but I think I might grab the 800 stretch kit and go straight for gold.
    Anyone know if Align will make speed fuselage for the 800's as well?

    i have the same bird . I threw a vbar neo in mine it hovers like yours. I dont need the 1500 rpm hed speed that is the minimum my setup will alow for proper governing i fly it with a vbar bank of 1900 an fly with a 6s its quiet and fun to fly but 800 rpm? is a little on the low sie. I flly it with a 5s and 4s both same packs same discharge rate at a bank of 1500 meant for a 12 s and its a bit to much. i have a 12 pinion. if i change the pinion to a 10 can i get a bigger main gear or do i need to??? i changed pinions on my raptor and in't need to change main gears. my motor is a dominator 490 kv bl850mx. where can i get that same motor your using? thanks and btw the motor comes back piping hot but tha'ts flying in triple digits

    I always read DFC is no good for low head speed because the dampers are too hard and the blades can't "flap".
    But it seems these machines fly fine with it. I'm wondering if I should spend the money converting to a conventional FBL head.

    • @JohnWD40TC02
      @JohnWD40TC02  6 років тому

      The fly just fine at low head speeds with stock dampers, IMO FBL are harder to fly than DFC but others would disagree, it's just what you are used to.

    • @halleffect1
      @halleffect1 6 років тому

      yours seems to do just fine, hard to aurgue with video proof. I'll save my money for now and fly with the DFC.

    Is it easier to fly a bigger heli ie a 500 or 600 as opposed to a 450 size ?. At the moment i am also on HBFP

    • @JohnWD40TC02
      @JohnWD40TC02  11 років тому

      You will find that the bigger heli's are more stable which up to a point makes them easier to fly, the bigger they are makes them more intimidating and dangerous as they can kill.
      If you have mastered your HoneyBee FP then the next step would be a Trex 500, these are much better than a 450 as they are more stable.

    how can you lower the temperature on the motor? After 8 minutes of flight mine rises to 140deg. (no 3d). suggestions? Thanks

    • @JohnWD40TC02
      @JohnWD40TC02  11 років тому

      Hi Edwin,
      You need to make sure your heli is geared correctly for the head speed you are using, I changed my motor pinion to a smaller one (10t) which will raise the motor RPM and keep the temps down.
      I also changed my motor to a lower KV version, these motors have a lower max RPM so you can have a lower head speed while keeping the motor running efficiently.
      You should run the motor at around 80% of it's max speed, running it slower can cause it and the ESC to overheat.
      It's all about getting a combination of the right motor and gear ratio for your desired head speed.

  • @mickcarson8504
    @mickcarson8504 11 років тому +1

    Geez... by the time I own one of these, I will be 60! How much do these cost with their RC? I don't want shit acrobatics. I just want one like his, at slow revs. This flies beautifully and stable too. I once owned a scale Jet ranger, size 60, slow rev rotor, like the real thing. You're also a good pilot. How do you keep it still and responsive? Is that the way they fly? Is it gas or electric? Sounds terrific. Your neignbours think you're mowing the lawn with it.

    • @JohnWD40TC02
      @JohnWD40TC02  11 років тому +1

      The 800 class heli is stable but you need a good setup to get the most out of it. Make sure the swash is dead level and you have zero pitch at mid stick, it's very important to make sure the blades are tracking spot on.
      Once that is all done you need a good setup in your transmitter so it will respond to your commands but doesn't roll to quickly.
      All this is made harder when you run a low head speed as I do, the heli needs to be geared correctly for the head speed you are using or it will overheat, I ditched my stock motor and used a low KV one to keep it in the correct power band.
      This this is an electric version which gives out more power the the gas (nitro) equivalent.

    • @mickcarson8504
      @mickcarson8504 11 років тому

      JohnWD40TC02 quite a beautiful model. Btw, what do you mean by zero pitch? Are you saying the swashplate needs to be set flat from all points of the compass? And for you to have done the correct gear settings for slow rev where did you get the main rotor gear? Is it the original gear or did you have to change it? And the motor, did you change the motor or just the gear; since you said that it overheats. Did you change these gears or the speed controller? What about the gyro, isn't it affected? I watched this video fron start to finish. Very nice and sound good. But what impressed me the most is how stable it is when hovering. Mine are smaller and tend to sway all over the place. They just won't hover where you want them to hover. Take your eyes off the heli for a second and it starts to drift in the direction the wind is blowing. 

  • @trexinvert
    @trexinvert 11 років тому

    Now that's exactly how to hover in a backyard. Whether you're beginner or pro. No fkn around. Steady nose. Steady altitude(I'm sure you were fighting some wind). Very few pilots have the "patience" to do only that. Plus, almost 15 minutes flight. Purpose for any kind of "close" quarter flying is just for testing. Not for the Attention Deficit or Adrenaline junkies.
