The bungee to powered flight went OK, but I had hoped for much more power. When I got home, noticed the prop was on backwards. Its a pusher you know! It does not pay to be in a hurry. I did not order pusher props. I have got the prop label facing the motor now, which puts the LE of the prop in the right direction. Just tested with proper prop. The 8x4 prop was 500 watts and 32 amps. The 8x6 prop was 750 watts and 49 amps. This was on a slightly tired battery. The manufacturer says 740 watts max continuous so that's close enough. The 80 amp ESC is good. I will test fly tomorrow with the 8x6, hopefully at 1/2 throttle. In time, I'll zero in on the best CG and hopefully get rid of that up trim. at the slope, you don't need motor...........
@@miniphase 300 W/lb.........that is attractive! Word on the street is 100 W/lb is enough to fly. Getting it airborne from flatland is the challenge. I knew the bungee would work, but next up is a side arm launch which requires some kind of secret sauce plus oodles of power...............all without a flight controller, SAFE or AS3X. At 11 oz/sf, this plane has a significant stall spin feature if you get the AOA and airspeed wrong (ask my how I know). Believe it or not, I actually became bored with slope flying, after 30 years, and longed for the challenge of thermal flying. One thing for sure, this plane would perform great on the slopes..............without a backwards prop.
Carbon fibre and lead are a peculiar combination in an aeroplane?
Any idea how many watts you're pulling Kent? I'd call that a successful test session!

@@highster with the 8x6 you'll be getting 300w / lb.... that should be plenty good! not quite sure how you're coping without any hills!!
