Is ther another product that could be used on pattern planes that would have pull pull cables connected to a bell crank servo type arm of equal length top and bottom on the inside of the fuse with control arms on each side of the fuse connected to each elevator horn? Does such a product exist. It would be a combination of bell crank and pull.
You can make the MK a bellcrank (I do this on my models) just make a double arm from PCB and bolt it onto the MK single arm above and below the output shaft. You will have to drill the lower hole in the little "***" on the single arm and use the standard holes for the other bolt. It works real good.
