This is an 2.5” AirBlade Eclair 3K V2 that I built last October to replace my beloved Diatone GT-M2.5 build - that I lost to a very, very, mean and unpleasant tree. I like small drones because I live in Southern California and theres people everywhere. I like to fly these little guys around my house at night so small, light weight, and the low light friendly Eagle Micro RunCam were a must. Maybe there’s better options now but at the time of build the Micro Eagle was/is amazing in low light. Plus this one has smart audio! RotorX RX 1105B 6500kV V2.0 Beast Mode motors to match my Diatone's 1104s.
I wanted to use a HGLRC F4 Zeus AIO board to save weight so I contacted “The AirBlade UAV Team” and asked them if the board would fit their frame and they said it would! …They lied! It does not. So I had to dremel out the forward support bar on either side of the cage and that let the Zeus board fit. No big deal. I had first built this with a Mach 2 VTX and a FrSky XM+ and a Foxeer Lollipop 2 antennae. It was a TIGHT fit and too heavy. The AUW was 103.6 grams and it took some serious sanding and filing to make it all fit. The cage was just too narrow to fit it all. Plus I had to have a board for the VTX to sit on since the Mach 2 doesn’t have any small mounting options.
So I rebuilt the thing - took out the VTX, board, antenna, XM+, and cut down some of the motor wire shrink tubing. Installed a HGLRC XJB TX20 V2 and a FrSky R9 MM. That brought the weight down to 92.5 grams and everything sits inside much happier now. It still has VTX smart audio and no more drop outs with the R9. Much safer for flying around the neighborhood - and I don’t fly too far out so the VTX has been fine so far. I DID notice a bit of a drop in quality going from the Mach 2 to the HGLRC but that was expected.

It flys alright, its a bit twitchy. Not as well as my GT-M2.5 did. I wish there were 2.8” prop options as I think they would fit this. Maybe ill try some other 2.5” in the meantime.
