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 RCM&E's publisher, MyHobbyStore at
The modelflying section is here from which the plan listings can be accessed including rare items transferred to the previously unobtainable 'X-List'.     
CNC kits, wood packs, canopies, cowls and plastic parts can also be purchased. You can also call MyHobbyStore on 0844 848 8822.  
All the plans MyHobbyStore sell 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. A new on-line article archive has just opened featuring many favourites, click here to go there. Many build articles have been re-published here at 
From February 2010, MyHobbyStore is offering all readers access to this extensive archive. If you want to obtain the article that accompanied a plan then call 0844 848 88 22 or email preferably quoting the title and issue number/date (NB: they will supply the entire back issue if possible). Prices start at £3.00 plus p&p.
If you've always wanted to build your own flying model but are unsure as to how to approach the challenge then I would suggest MyHobbyStore's 2009 plans handbook. This publication reproduced the popular plan articles by Tony Nijhuis (including his Sky 40 Trainer) but also included an excellent 8-page beginners article by the late David Boddington, one of the most respected authorities on the subject.
In addition 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. Do drop by if you're seeking help or guidance.
