I've also struggled with the issue of locating scale retracts for the Cessna RG lineup. The retracts by Ramon Torres at www.rtaerospace.com are the only ones I've found that actually retract in the scale method. Sure, you can get a set of F-104 or similar retracts that just retract back at an angle from Robart or CJM, but to get the spindly, curved struts that drop down and then back like the full scale planes I don't think you'll find any out there other than the ones that RT has custom built.
