For bashing, [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXMZU6&P=]Hot Bodies Lightning[/link]. I just did probably 50 jumps the other day, with plenty of side landings, upside-down, etc. and finally broke off the wing after about 5 tanks. Before that I hit a pile of bricks, head-on, at full speed... it just flipped and kept going (nothing broken). There is a [link=http://www.bigsquidrc.com/reviews/hot_bodies_l2rr.php]review on Big Squid[/link] that also attests to its durability.
