I think we will want two configurations of the bracing since we are moving forward with designing 2 solutions for the payload and each will be different
For the cone version, bracing should be at a height specified by Conall’s cone design to mount the fixed part high enough
For the pump design we are thinking of mounting the submersible pump on the brace, with the brace on the bottom like you have and the tank mounted to the arms within the CF plate perimeter (this shouldn’t interfere with what you are doing
we will probably want a more circular or square design for the brace in order to allow us to dump the water without loads of deflection when the water hits the brace
I think we have a 30 degree angle in Conall Kingshott ‘s geometry sketch, if you can CAD the bucket and make an assembly with main and the bucket so we can see how this fits, I think that would be helpful in determining the angle we should use

Notes:
Pump does not have to be at the center (this helps with square bracing)
Use CF tubes for bracing
Copy old pegasus leg joint for anti-tipping bars (COMP24 folder)
Keep everything parametric still
Use Conall’s method for tipping bar length

Current State
Settled on 20 degrees
Added tube support at the bottom, will need 2 tubes total
Need to adjust the height of the support, currently the pump goes through the floor
Will start working on anti-tipping bars
From now on, I will create one assembly/component configuration for each payload variant

Payload CAD Review Notes
Increase clearance from top of the barrel to bottom CF plate to 80 mm
Make sure cavity is big enough for electronics cables in new motor mount for atp

More Updates
Anti-tipping bars finished and fully integrated into motor mount with cavity for cables.
The manufacturing of the main pieces of the landing gear is done, only the cf members left.
Drawings for the cf members will be done soon, need to rethink pump mounts as well. I also need to adjust the dimensions where the 3D printed part meets the aluminum bracket (0.4 mm) since it was a tight fit.
Added depth limiters due to vague bucket dimensions, they reach out until the OD (22”). This helps meet the clearance with the scoop servo, which is currently around 90 mm.
There’s a 1mm gap between the end of each landing gear hole and the tube, as advised by Conall Kingshott.
The angle of the gear is still 20 deg.
