Isn't a Y harness needed for dual servo airleron? (and this single?) Why 2-12" extensions needed for? Just one to get from Rx to airleron servo and isn't 6" enough?
Also, I assume some glue is needed? Epoxy? CA (which thickness)?

While we are at it, anyone care to compare the differences between the Phoenix Dolphin and SIG 4* (although than the $50 price difference)???
