Hi Bryan,
Personally I would just glue down the outer housing using something
like Loctite 401 CA glue. The only reason I am suggesting this is
because you sound like your flight will slam it a bit. If you were
doing regular flights, say around 15G I wouldn't bother. Just clean the
PCB around the block as best you can with something like metho, wait for
it to dry, then apply the CA and hold the housing in place till it
sets. Don't use excessive glue and glue up the internals of the
terminal blocks! 401 is great for sticking higher mass parts to PCBs and
I have been using it since the 1980's for such things.

Hello Keith, Bdale & everybody,
I recently bought a new TeleMini and just sat down to mount it to an avbay. I
noticed the switch terminal block is loose. The solder joints look good and the
internal metal posts don’t move when I wiggle it. It looks like the only parts
that move are the green case, the screws and the clamps. There is a space
between the PCB and the bottom of the green case (maybe 0.75mm on one side).
I’m hoping I can just put a dab of epoxy between the green case and the PCB to
secure it.
I’m planning on using this in a record attempt in a few weeks. The rocket will
get a fairly abnormal amount of abuse with multiple 80G launches that weekend.
I don’t think it’ll be a problem, but I wanted to be sure.
Here’s a video showing how much it moves. The ejection charge block is solid.
The switch one moves…

Soooo…epoxy it & move on?
Thanks,
