I`m an HO scaler converting to N and I plan to purchase an Atlas RS-1 off Ebay and I noticed it had the Rapido (I think it`s spelled right) couplers.My question is,are these units easy to convert to knuckle couplers, the Micro Trains ones to be specific?
Rapidos they are!
The older RS1 and RS3 are a straightforward conversion.
You need a Micro-Trains 1158 conversion kit, which contains front and rear pilots, a pair of assembled coupler units, and some screws. It's easy to put in if you have a small razor saw and don't mind cutting chunks out of a model. You need to use the saw to cut the whole rapido coupler and its box off the truck, then you cement the pilot in place and secure the coupler in the appropriate opening with a screw. Took me about 1/2 hour to do, not counting cement cure times.
Simple!
Now, coverting an old Kato F3 to M-T couplers, that's an unspeakable horror
