Hi
Im in the middle of building a flair Swallow EX.
Im about to hinge the control services.

the fiber hinge disks are the up to it !
in the past I have always discarded them.

the manual says use low velocity ca

Does that mean thick so it dose not run quick ?

or does it mean thin as in low in density ?

do you dry fit them first ? and apply glue while there in place.
many thanks

Hi Geoff
Yes you dry fit the control surface you are hinging with the hinges in place and when you are ready you use thin CA so that it will wick up into the hinge socket! I don't know about the Swallow but most times when building a plane one of the last things you do is glue in the control surfaces. Once they are on the plane it makes handling, building and covering much more difficult. Although I mostly use hinge points I have used cloth hinges with great success. Good luck with the rest of your project!

Are you sure it doesn't say "low viscosity" ? That means thin, which is what you should be using.

Fit them dry then add a FEW drops of thin CA on each side. Provided the slots the hinges fit into are a good neat fit they're fine. Note if the slots are too tight the glue doesn't get in properly, if they're too sloppy it doesn't stick well. Don't try to glue them in one side first and then fit them to the moving surface. They must be correctly positioned before you get any glue near them.

Thanks for the quick response guys
ye your right it says viscosity the spell checker can not cope
with my spelling
I thought it would be thin so the glue is drawn into the joint by capillary action !!
thanks Geoff

geoff,

Here's a "How To" article on installing CA hinges. It's worth it to taks a look.

Thanks MinnFlyer
most useful
especially the pin to keep hinge in the centre
