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

Your just way under powered try the Hacker A30-16m and 35 amp ECS always with 3 amp bec  we have used the 11x7 prop unlimited vertical on this I even flew it in a 35 mph wind at a Chicago contest just for kicks, for slower down lines try lower pitch and bigger diameter. Theres a thread on RCU elertic pattern that should help. I agree maybe not the best but it's still can be done. Think if you work with it it would be exceptable if not just plain fun.

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!
