Hello,
Good to hear from you Neville, hope all is well.
I bonded my CS14 brackets the old fashion way with Aeropoxy only.
Glad you had a note that it has not been a problem. This leads me to
another question. When bonding in the ply for the tri-gear legs the manual
says to use Redux and flox to bond the ply (page 29T-5). Is Redux also used
to bond
the fibreglass or is Aeropoxy used as usual?
Thanks,
John Eckel, A230
