Geoff,
That battery pack is a ''C'' cell pack and is going to add a lot of extra weight to the plane
Eh, not that much... only about 2oz or so on a .40 trainer.
He's only talking about 4.8v 2000mAh packs.
Here's a direct comparison:
Hydrimax 700mAh 4.8v - 2oz [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXPYL6&P=ML]Click me 700mAh[/link]
Hydrimax 2000mAh 4.8v 4.3oz [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXNRH6&P=ML]Click me 2000mAh[/link]
The LT 40 is not going to notice the difference at all.
