This is the Lacey M-10 (MAG-1524) a 40" span, semi-scale design for .25 two-stroke engines.
We're often asked about the RCM&E plans range - where they can be seen and purchased, how the accompanying build articles can be obtained etc.
The plans are sold by Sarik HobbiesCNC kits, wood packs, canopies, cowls and plastic parts can also be purchased.
All the plans were originally featured in either RCM&E Magazine or former titles such as Radio Modeller, Silent Flight or Radio Control Scale Quarterly.
A complete archive of these magazines is maintained by MyHobbyStore and article re-prints can be purchased. Many build articles have been re-published here at 
RCM&E has published a three-part series by Peter Miller (another highly respected designer) on how to build from plans. These can be found in the Feb, Mar and April 2010 issues.
The challenge of building a model from a plan can vary in complexity to an enourmous degree and sometimes even the best articles are unable to encompass every technique or challenge. RCM&E's forum here at is one of the largest and friendliest of its type and has a 'build' and 'beginners' sections where flyers document their projects, share ideas and help solve practical problems.
