The E-Flite Tandem design solves the most serious control issues I encountered in the Twister Skylift. Its frame and lower mass are less subject to mast vibration. Its differential front and rear rotor speed control of fore and aft movement make it less susceptible to "rocking horse oscillation" when it is throttled back to descend. That oscillation was often a prelude to loss of Skylift control, so E-Flite's design of their Tandem is a really welcome improvement.

That said, tandems are by design, trucks. They are built to carry cargo, and need to be flown a little differently from other co-axials. A truck can be as much fun as a Porsche and a lot more useful.
