Quick Disclaimer that this was supposed to be a HDZERO build, but i dont have the budget to do that right now XD so if you plan on using the HDZ AIO it totally works.
Additionally, I ordered the Twiglet (Betafpv) frame from Aliexpress for 1€ and did not get the camera mount so i substituted for the Larva-X cam mount that i had on hand. Sorry for that.

This motor-Prop combo has been on my mind ever since i saw the spec- sheet on my first 2" build. It is insanely efficient and we'll see how this goes.

If you want to make changes to the design, please do so and let me know what u changed because this is as light I could get the quad to be with what i had XD

Frame
Shenstar Twiglet by BetaFPV + Larva-X canopy was around 6.5grams and it was the lowest i could get, if there are lighter frames do let me know :)
Motors
We're using the 1202.5 11500kv with 2.5inch props

Props
If you see the image above the motors get 10.34g/W specifically on the Gemfan 65mm props so we are going with that.
FC & ESC
Betafpv 5A 5 in 1.
only the 4 in1 was available for me at the time so i had to add an ELRS module.
You can ofc use the HdZero AIO
Camera
you can go with any Nano cam but I recommend a cam with no wire stick outs as it may restrict your camera angle.
Battery
Im still going with 1S BT2.0 lipos HV as it gives the lowest voltage sags and flies for longer.
Also can be charged with the Vifly charger on the go ;)
Weight & Calculations
In total you should get around 50grams, that is approx: 12.5grams per motor which should be around 13-15% throttle hover.
