I have a limited supply of Rotary Driver System couplers with a new tree of adapters that will not be generally available for some time. This tree has adapters to fit all VOLZ except the ZIP. Another new one fits FMA 80/90/95/100 micros and the ACE 8112. Tree still has adapters to fit standard Futaba, Airtronics, JR, Multiplex, Hitec 60/80/81/85/101 and FMA 300 series. Price remains $5 a pair. Will be shipped only Priority Mail in USA. Add $3.20 for that. Remit to the address below. See RDS website below as the primary source of current information.
