Hi Dave,
When I did my last post I quickly signed out and returned to my latest project. It is only now that I decided to take a break before starting the bending of the landing gear.
The glue I use is a foam safe craft glue, (clear), which I purchase from a local variety discount store. The brand is "Office Central" and it costs me $2.50 for 100ml. used properly and not in excessive quantities a single bottle can assemble 2 large or 4 small FT Designs.
Be very careful when scaling FT designs as the channels of foam removed can be a problem if you change the scale too much. My preferred method is to use metric graph paper and redraw the plans full size. This also allows me to alter the design by just drawing the changes on the plans. In your case a little extra Hotmelt will fill the gaps if any.
When cutting out please use a long, (1 metre), steel rule as a blade guide as it can save you a lot of issues of what I refer to blade wander, (my way of describing my inability to cut straight lines free hand). To save yourself even further heartache before you score the hinge lines for control surfaces or the wing Leading edge I VERY STRONGLY recommend that you cover the reverse side of the sheet with clear packing tape to reinforce the paper, (Make sure that you rub the packing tape into the FB to remove as much air as possible).
This tape stops the paper, (which you were not supposed to cut), from breaking or tearing when you fold it or over time in the case of a control surface hinge.In my own case I tend to wrap the entire plane outer surface in packing tape, (coloured purchased from KMart), to provide moisture and impact protection.
May I enquire as to the subject of your first build and your chosen flying field environment? Have you selected your electronics yet?
Will check this thread later this afternoon after I sort out the landing gear
Try to never criticise, but rather educate and assist where needed. I do not know it all and often the one that is educated is ME!
Catch you later!
Bob
