Starting to resemble something that eventually will fly. B) Nice work Kevin. By the time you have got to wing 4 you'll be thinking "Why did I not do it this way earlier!" Myself I have said this many times with multiple items that had to be made up identical. :lol:

For the first wing L/E sheeting i just formed it around the bathroom towel rail but had some difficulty fixing. Subsequently shaped them on a tighter radius allowing them to fit like a glove dry. Now they can be fixed without pins.

Definitely getting the hang of this old building lark !

wing No 4 nearing completion. I had to rework the upper wings to introduce ailerons riblets while retaining the wing shape then cut out the skeleton structure.

I glued the aileron L/E ply wrap to a sub spar - then steamed these to preform it. Masking tape used to hold the ply around the front then clamped to ensure a good bond to the upper sub spar.

Its build time again and phase 3 of my Stearman build. With all the major components completed by last April its time to blend the joins and rig the parts .

The winter storms finished off my 10yrs old patio umbrella but i saved the alloy ribs which have come in useful to make setting bars to rig the wings in conjunction with a string line to align the wing spars.

The plans just call for bonding these wing root tie bars to the first ribs but ive fitted some light ply plates to increase the bonding area and used small screws to set the wings fore / aft angle

Many of you know about my love hate relationship with Saito gas engines so in the end I divorced the FG60-3 and sourced a new partner.

This is a Valach 70cc and reputed to be one of finest R/C motors and produced in Czech which i'm currently shoehorning into the Stearman.
