test stuff for rail buttons and motor casings

[muleParticipant]

I had to look a this one too. I have PML guides on two rockets and will be using the Acme T6 AL ones on my Talon 2 and Vert. Assault. I’m using pistons on everything but the VA, so I didn’t want to have anything inside the bt.
I have experience with the rivnuts and like them. We used them in fiberglass repairing Corvettes – back in my body shop days….

Mike,

Removing those PCB mount SMA connectors can be a bear, especially with a ground plane on the board. I generally sacrifice the connector, cutting bits of it off at a time with some strong cutters, to reduce the thermal mass before desoldering. I’ve got a nice Metcal iron with both the pencil and tweezers if you want me to do any rework on the DC20. Let me know if you think its repairable. I also have some of the connectors in SMA(threaded) and SMB(snap-on).

Actually , the SMA connector is hanging from a short pigtail (about 10mm) . See your PM.

The trailer will be moved to my house IN Longmont sometime tomorrow or Tuesday. I also have multiple rails in my garage for you to test fit with in any event. You would be welcome to come by with your bird and try out the rails and use any of my 54mm cases for a test fit. (I have cases from the shortest Aerotech 54mm up through an AMW 2550.)

Oh yeah, the nuts inside the airframe are purely up to the builder. Many folks use T-Nuts, with or without a little piece of wood. Some use Riv-Nuts which are inserted with a special tool and crimped into place like a rivet. Some folks just embed a regular nut in thick epoxy… all depends.

Warren Ill touch base with you in a couople of days, after I get the buttons mounted.

I use Well Nuts. You can get them at Ace Hardware. You just drill a hole, put these in and then turn. They are rubber and expand against your airframe and keep them in place.
