Just got my FliteTest Gremlin (which is just an EMAX 1104 Power System Combo with a Delrin Frame) and got it put together. So many tiny wires!

Ended up wiring all of my ESCs backwards, but I'd read something or watched a video where someone suggested running reverse prop rotation to keep your camera lens clean. So... I meant to do it!
To make everything behave, I popped into the CLI tab of Beta flight and entered 'set yaw_motor_direction = -1' then 'SAVE'. Done and done.

AUW w/ 350mAh 3s: 109g

Technically not rated for 3s but we'll see how it goes.

How to Enable DSHOT (Modified from HERE) :

Obligatory "You do this at your own risk, no guarantees".

1. 
2. Upgrade your FC to Betaflight 3.1.6 or higher so you can have DSHOT in the options under config.
3. Connect to Betaflight and go to the CLI Tab.
4. Enter the following commands:
   resource PPM 1 NONE
   resource SERIAL_RX 2 NONE
   resource MOTOR 4 A15
   SAVE
5. The first two commands remove the resource assignment of A15 from PPM1 and Serial_RX2, then the third adds the resource assignment to Motor 4. In case you were wondering.
6. You'll be able to set the ESCs to DSHOT and have it actually work now.
