Note that it is RCME ( Radio Control Models & Electronics which is now called RC Model Airplane in USA ) not RCMW ( RC Modelworld ) Both English magazines of course. The November RCMW free plan is Swizzle Stick a fun fly model for 25 to 30 two strokes. This is also by the same designer!
So it is the November 2010 RCME / RC Model Airplane with the free plan for RV3 which might still be available. The USA & Canada phone No is 001 877 363 1310 and I expect they could sell you a back issue at this time. ( usually cheaper to buy a back issue with free plan than buy the plan alone! )
There is a thread at
