West Wings Skylark build thread
Happy Days:
Checking that the fuse, wings and any other part of the build is straight is something that is a constant part of any ongoing build. Whenever you’re about to glue parts together check first to ensure that the build is straight. Check it again immediately after glueing, and in my case, I check it again when the glue is set,…not that there is normally much I can do about the matter if it isn’t! :roll:
Your fuse is of a ‘built up’ design. If there is a slight bend or twist you might be able to straighten it out when you come to fit the covering.
By applying a little more heat to the covering on one side of the fuse you might be able to shrink that side a fraction more, so the covering pulls the airframe straight. Of course, this can only happen if the covering on the opposite side has enough slack to allow the fuse to straighten.
Talking of covering,……fit the tail to the fuse and then cover the airframe. Start covering on the bottom, and work forwards and upwards. What I mean is, start at the underside of the tail. Then do the underside of the fuse working forward, overlapping the joins of the covering by aprox 5mm. Try to ensure there are as few joins as possible.
Next cover the sides of the fuse, again starting at the back and working forward. Then of course finish the model by covering the top, starting at the back and working forward. The idea of starting at the back and working forwards is so all the joins in the covering face backwards so if any of them start to come unstuck they wont catch in the airflow and open up all the more.
Small twists and distortions of the airframe wont stop the model from flying so don’t worry too much if the finished produce isn’t perfectly straight. Some of my models that have been repaired umpteen times are quite bent, ( the fuse of my P6 looks like a banana) but they still fly. I just have to trim out the tendency for the models to fly in circles! :lol:
Oh, and finally………turn your blood predictive text off will you. :evil: Then may be we can understand what you’re talking about…….”I think the afternoon end fuselage is slightly favouring the right “ WHAT??? :!: :!:

Well, in the afternoon I do tend to drift right and become a grammar fascist...
In the length of the fuselage, the warp is about 5mm. I was hoping that you would say that the covering will pull it in as it doesn't take much pressure to take the warp out.

As of last night, both wings have most of the balsa sheeting on. In some fashion... I've found it exceedingly difficult to keep the sheeting in place to allow the glue to set. Using clips and tongue depressors seemed to work ok when you finally got the clip to stay on.
The leading edge requires shaping and I need to fit the extension wires for the aileron servos and leave a hole to pass them into the fuse. I think a little epoxy to hold them in place?
Just the sheeting to be done on the nose and base of the fuselage as well.
After that, out comes the iron!

Hi angry,
Try using cellotape to hold sheeting down.
John.

Latest update:
Wings completely assembled; now require the leading edge to be shaped.
Fuselage has the snakes in place, but not glued to allow alignment with the final position of the servos.
Some sheeting to be done - talk about springy, it just doesn't want to stay down to get stuck!
Pics to follow.
