As a happy owner of Mobula8 with HD (wasp runcam link) I very quickly bumped into the reality:

• analog version has 42-48 gr, digital - 80
• you can't use 1s battery - DJI link is unable to start from 1s
• with the battery 660 mah the total weight is near to 120gr
• this heavy drone has flying time less than 3 min and become broken very fast, extremely fast
• heavy weight and aggressive s2 doesn't allow to use this drone indoor

But not all is bad. Need to accept - this is for outdoor only.
Let's optimize

• Replace the WASP regular camera to NANO
• make the Vista naked + drill all mounting holes from 1.6 to 2
• Buy Draknight
• Make the groves on Al frame to fit the camera
• Move the reast of staff to it
• pay attention to use 10mm bushing and 25mm M2 screws to have the space for the motor connectors and mount the original battery holder

At the result

• very steady and smooth flying
• min 3 minutes flying with the potential to 4
• unbreakable frame (for sure with the same assumtions)
• very quiet

Recommend to resolve the issue, or move the HD to the 4"+
