LOC data missing

[dbcook]

This issue lists the bits of LOC Precision parts data that are missing from the LOC website

• ID/OD of BT-1.90 Data now published, fixed
• ID/OD of all cardboard tube couplers (note some data available on the Apogee website)
• ID/OD of all cardboard tube coupler stiffeners
• Masses of all centering rings but especially for the cluster rings where OR cannot compute it volumetrically

more coming...

We owe LOC a spreadsheet like the one we sent to Bill listing the missing info for them to fill in.

I've shared the spreadsheet with Dave Barber of LOC as of Nov 12, awaiting response.

Is there a reason that the nose cones don't have <ShoulderThickness> and <EndCapped> set correctly?

[dbcook]

Hi Ahmed, This is because OpenRocket 15.03 does not allow you to specify those parameters in a .orc file, although they exist in the UI. Some special effort was made to allow construction of a reasonably accurate mass/CG for LOC nose cones in the face of this limitation. There is a special note about how to handle this in the README, look for the section "Hollow One-Piece Plastic and Fiberglass Nose Cones".

I read that before I asked the question. Is there a plan for dropping support for 15.03 so that these can be used? And note, users can't actually read the xml comments, right?

To clarify: If the comment wasn't in the file about the workaround, I would've simply submitted a PR with updated values. The comment is confusing enough that I decided to ask here first.

Sorry for not answering this earlier, was dealing with major damage to my house at the time and I lost track of it. I was planning on retaining compatibility with 15.03 on at least a GA-2 basis, I.e. until there have been at least two major releases of OR. So far we’ve had one, and I imagine it will a year+ for there to be another.

I understand there have been some changes in the .orc syntax in the 22.x release, but the devs didn’t coordinate with me and I don’t know what they all are beyond the obvious ones like rail button support.

On the topic of LOC parts data, I haven’t heard back from LOC after sending them the spreadsheet.

As of now the ID/OD of the 1.90 tube have been provided on the locprecision.com website; however that's the only missing item that has been filled in. Accordingly the 1.90 tube and ring sizes have been fixed in 1.0.0.5
