This is a 51” wingspan traditional style fun-fly model designed by Graham Legg for .36 to .46 2-strokes or .36 to .52 4-stroke engine and 4 function R/C. Constructed it is all wood, the 2-sheet plans (not included with wood pack (MW3400)) showing much detail. Not for beginners. Building your model from a Sarik Hobbies ‘Laser Wood Pack’ semi-kit removes the need to trace and cut your own intricate parts. It will be necessary to purchase additional sheet and strip wood from your local model shop to complete the model.
