I now have the A20-30M, Hacker and Kokam 700 3cell pack, the plane seems heavy but flys good. Is there a better setup to help reduce the weight?

Yup,

AXi 2204/54
And a Thunderpower 2cell 730mah
Some light servos. Bluebird 303's(306 on ailerons) or Futaba s3108's or the new s3110's
Tiny balsapr.com 10A esc
and a little Bluebird 4ch rx with the case removed.

yes there is

AXI 2204/54
P 10 speed controller
Futaba 31010 on the ailerons and some light servos for the rudder /elevator
Kokam 3cell 340's if you can find them or kokam 2 cell 640's
I use an M5 V2 reciever with a light anntenna wire

Just build light use less glue and just come up with things to save weight like shorten wires....

I think I have seen Devin post his Shocky setup 1,000 times!
Search is your friend.
BTW- Devin's setups and shockys in general, are super dialed and fly awesome indoors.
