RBean

Does anyone know if the RS666 electric actuator can be installed in Robart 701 retracts. If so would have robart strut ready retracts with electric actuator. These are air up spring down retracts using a 7/16" diameter strut in a 16 lb CMP Zero. Robarts work good except now I have an air leak. Leaks down from 100 psi to about 50 psi in about 15-20 mins. and stays there. Havn't been able to find it with usual small paint brush and soapy water technique. Why fight with it if the electric retro will fit? I have an e-mail into Magnum RC, hope to get an answer from them. Thought maybe someone here might know.
