[NSRCA-discussion] Anyone use a Brio 10 (little electric) topractice pattern?

RE: [NSRCA-discussion] Masters 2007 Figure "M" question - verticalsegmentsA brushless motor is lighter for the same power output compared to a brushed.  Since you think it acts too heavy, that could help considerably.  If you are using Nicd/NiMh, moving to LiPo can give increased durration AND reduce weight.  In combination, LiPo and brushless replacing a brushed system using NiCd will make a VERY large difference.

A local club member has one... It hasn't been flown much, but appears to not have the issues you describe. (from observing, not me flying it)  He is using brushless and LiPos.

  I bought one of these to enable flying closer to home, and I expected that it would fly somewhat 
  akin to a 2m pattern plane.  It does not!

  - the wing loading seems very high.  The glide characteristics are more akin to a winged brick 
    than a pattern plane ... it really seems to need to land with power (or at least very nose down
    until the flare)

  - Flying it with a Speed 480 - this seems quite inadequate to the task.  Uplines are only
    100-150 feet before it runs out of steam, and you simply cannot pull into a vertical slowly
    and expect the motor to "tractor" you upwards.  It also seems slow, but I'm new to these
    little electrics, so perhaps that's normal?

  - no braking on the downline at all.  Pushing the nose downwards causes it to accelerate
    at approximately 9.8 m/s/s  (32 feet per sec squared for our American friends) ... :-)

  Any suggestions?  Has anyone found a way to lighten it?  I'm using a 2150 mAH pack, micro
  servos, miniature rx ... can't think of any obvious way to decrease weight.   I don't have a spinner
  on the plane, will that reduce performance?  Would an AXI 2808 give better performance?

  And lastly, if I'm expecting too much of this airplane, does anyone have any good recommendations
  for a mini (ie, school yard flyer) size pattern plane?

  Thanks!

  Amar
