yeah. split elevators is a pain for those that don't have a nine channel radio. my hitec eclipse seven channel doesn't support split elevators. technically you can do it but if you accidentally move the ch. 7 dial just a click, the elevators aren't even and can easily lead to havoc in the sky (soon the ground). i assume that for some other radio's you can turn off the dials you don't use or that there may be a special mode for split elevators.

anyway, i think that unless you have to have two elevator servos (for torque and short linkages) i prefer the bellcrank, the U shaped wire or the Y control rods.

the servo mod, while not difficult, does give you something extra to worry about!

good luck!!!
