I am considering the change from Futaba to CORE. With all my turbine models I will use the PBR26 into my existing PowerBox installations (which may be, Competition SRS, Royale SRS or Mercury SRS). BUT, what receiver(s) should I use in the many other models I have that have between 10 and 18 channels?? with no other power or channel extention systems? I really don't want to change all those models to now include an additional power/channel distribution/expansion system. Many of these models have been flying with a single receiver and single battery for more than 10 years already.
