O/K. Did not think it possible, but I shoehorned in some normal size servos. I now have mounted a pair of analogs and I internally reversed the one for the L.H. wing. Unfortunately, since not programmable there is a difference in travel if tied to the same channel, so off either retracted or extended. Will have to go through my limited supply of analog servos to see if I can get a better match or figure out how to get back one receiver channel now used for an Rx battery status indicator.
