I have both (LA Racer and Mach II). It seems the Sky Raider wins more often than the LA racer for some odd reason, and the SR Mach II is $10-15 cheaper. However, I do like the dual ail. servos on the LA for mixing in flaperons.

PS: Both of these are ARFs, not RTFs. If you want a nice low wing "kit", look for a TF Bonanza!!
