   - Walksnail Avatar VTX doesn't have passthrough holes for 20x20 mm stack (or any other for that matter) but long screws from the bottom of the frame have been used instead for mounting leaving decent space below and plenty about the VTX   - Walksnail Avatar VTX doesn't have passthrough holes for 20x20 mm stack (or any other for that matter) but long screws from the bottom of the frame have been used instead for mounting leaving decent space below and plenty about the VTX
   - Walksnail Avatar HD Pro Kit doesn't come with a camera mount and the hole pattern isn't the same as in RunCam cameras   - Walksnail Avatar HD Pro Kit doesn't come with a camera mount and the hole pattern isn't the same as in RunCam cameras
 +  - VTX is rated for 6V-25.2V (2-6S) while FC is 3S and doesn't have a 9V regulator, that's why VTX is directly connected to battery as there's enough headroom for that to not cause problems
   - The FC doesn't have pads for the beeper resulting in the connector needing to be used for it   - The FC doesn't have pads for the beeper resulting in the connector needing to be used for it
 +  - Emax Avan 3x2.4x3 feels to be the better prop compared to GemFan 3x1.6x3 and HQProp T3x3x3 which was also tested but concluded to have a too high pitch, Gemfan Hurricane 3020-3 hasn't been tested
