I have started building the Flair se5a,alls going well,and with anew saito for powering her.

One area in her construction,that is concerning me,is the engine mounting,two sheets of light ply,and two engine bearers glued to the top inner surface of each,each liteply sheet is then glued to each side of airframe,with no supporting measures,ie blocks etc under sheeting.

Is this a sound method?.i know the front former will be glued to the front edges of these two sheets,to help brace things up,but is this a sound method etc.

If you have built one before,did you carry out any mods etc

Any help on this very welcome
