A simple upgrade to the stock power system would be to replace the 13oz 7-cell NiCd pack with a 7.5oz, 2-cell, 3.2AH [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKRR7&P=7]BalancePro[/link] Lithium pack. The voltage under load is slightly higher with the BalancePro pack and the flight duration is 1.5 times as long. The 5.5oz drop in flying weight will provide a great gain in power when using the stock Speed 600 motor.

When used with the matching [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXKRR4&P=7]BalancePro Charger[/link], the Lithium pack safety and longevity will be maintained for well over 200 cycles.
