How to install the main girder (mock-up)

September 30th (Saturday) I checked how to fix the MAIN BULKHEAD on the left and right main girders (mock-up).

When calculating the load weight according to the airworthiness examination guidelines, it must be able to withstand a load of approximately 8G.

We need to further consider how to transmit the load on the main wing to the MAIN BULKHEAD.

It won't. Please refer to the photo. I used duct tape to temporarily fix it, but it looked a bit unattractive.

It's bad, but it's not bad.
