  1. 5.5HP@5500rpm. is that each?

     

    those motors claim to be more than 10hp each but I wouldn't trust them at that much. I think that tuning them for 5.5hp@5500rpm would be pretty gentle on both them and the battery pack.

     

    I had a look at these motors (and the full powertrain) a year or two ago as part of an electric mini project, but have you seen the price on an old mini body? utterly crazy.

     

    I'd be interested to see how well dale's flies, and what problems he has with it.

     

     

  2. those calculations look actually pretty good. the batteries are 1lb each, so 96lb worth of batteries. less than a passenger.

     

    each battery is 72WH (or just under), so that's 7kWh from the batteries. so 2 hrs of flight at 3kW.

     

    the real question is, is 5hp enough to take off on? I'd be pretty scared of how slowly it accelerates on ground roll.

     

    ozzie: I'm in the hunter. want me to electrify your Lazair? 010_chuffed.gif.c2575b31dcd1e7cce10574d86ccb2d9d.gif

     

     

  3. A sustained 90 degree banked turn is not possible maintaining height. There is no vertical component of lift. . Nev

    you could have lift from:

     

    - the nose being pointed above the horizon, and thus some of the thrust being lift

     

    - lift from any vertical surfaces (ventral fin, tail fin).

     

    not that these would give you enough lift.

     

    I have an urge to go build an RC plane that can do this now.

     

     

  4. My instructor tells his students "I'll let you get out of your comfort zone, but I won't let you get out of mine."

    My instructor's comfort zone involves banking the plane faaar beyond my comfort zone (I'm comfortable to about 50 degrees).

     

     

  5. so I now have my RA cert and 27 hours under my belt. I'm learning to navigate the 25nm around my training airfield with the remaining solo hours I need for the PAX endorsement. The NAV endorsement is a bit harder to get because my CFI isn't always around (I got most of my training from the SI).

     

    the goal is eventually CPL, but that's a very very very very eventually - I am in no hurry to get my CPL.

     

    how do I improve my flying? where should I go next?

     

     

  6. I wouldn't have care but they are making it impossible to get past Williamtown along the coast without a PPL. While there is of course the inland "Ultralight Lane" it is longer, not as scenic nor as safe as going up the coast.

    Having a look at the map an the restrictions, it seems that that area isn't restricted on weekends?

     

     

  7. I think it was more than 300fpm. more like 500fpm. climbed at something like 1700fpm without the instructor, on a cold dense morning.

     

    also much harder to force down. i may have pushed the "simulation" part of the exercise a bit by coming in low and flat, throttled back. pretty heavy.

     

    nailing that final crosswind landing when my instructor called me in due to adverse winds felt really good.

     

    just need my last 4 solo hours and I'll be about ready is what my instructor says.
