The MW aircraft are conventional three axis machines fitted with ailerons, rudder and an elevator  which is also fitted with an anti-balance/trim tab.  They all have rigid structures with fabric covered flying surfaces.
The above cut-away sketch shows the basic construction of the MW 5,6 &7.
All MW aircraft are constructed from readily available mainly commercial materials such as HE30TF or 6061T6 aluminium alloy, or S514 or 4130 steel.
The aircraft are assembled using pop rivets and bolts.  There is a small amount of Turning and milling and also some welding in the undercarriage and control system.
The wings are of mono-spar design, that is a single large diameter tube carries both bending and torsional loads.  An MW wing does not visibly flex in turbulence like other aircraft. 
Plywood ribs with spruce cap strips are slid along the spar tube in a simple assembly jig and are attached with a fillet of chopped strand fibreglass and polyester resin making an extremely strong and robust joint.
All aircraft are shown to comply with the relevant airworthiness requirements by stress calculation up to ultimate loads and a load test on the prototype airframe to limit load.
Each new design was extensively test flown to its limits including normal aerobatic manoeuvres  to prove the handling and structural integrity of the aircraft.
As can be seen from the various photographs the non structural nacelle shape can, within reason, be styled individually to personalise the aircraft. MW5,6,and 7 aircraft have been built with fully enclosed cockpits.
All aircraft can be de-rigged in some twenty minutes.  The 5 and 7 have folding wings and can be assembled by one person.  The 4 and 6 need two people to fit the wing, however some aircraft  have been rigged single handed by means of clever support frames. The all flying tail surfaces slide onto spigots and are attached with a single clip. De-rigged aircraft may be transported by trailer and stored in a normal sized garage.
All aircraft are certified through the PFA as home built aircraft.
Build time is approximately 1300 hours and average cost £2500 plus engine.
Over 90 MW aircraft have now flown and allowing for engine failures, have proved to be reliable and robust in operation.
The MW series of aircraft are the only microlight's in the UK which may be scratch built from plans.
