Love this 2.5in frame, it maybe just a 2.5in but it have a lot of space and possibilities to mount different sizes and types of fc, vtx, vista, 16x16, 20x20 or 25x25(center only) in the front or centre or back...the only fc that dont fit is 30x30 and why would anyone wanna use a 30x30 on a 2.5in?
i choose to use a whoop aio and stack the de-case vista on top in the center with elrs rx in front and a active buzzer at the back, i drilled the vista broad holes(M1.6 for heatsink) bigger to mount together with fc using M2.
The standoffs which are nylon so i replace it with a set of aluminium and this frame is now strong and rigid through a bit heavy at 26g

She is fat...Dry weight is on the heavy side at 103g for a 2.5in but still fly well with those emax 1106 6000kv motors on 3s or 4s throttle scale to 75%

Dry 103g
AUW with tattu 550mah 3s 163g
AUW with gnb hv 720mah 4s 175g
Flight time abt 4mins with 550mah 3s

This quad actually have a lot more power, was tuning with 4s battery and scale throttle down to 75% ... I put 2 profile for 3s 100% and 4s 75% throttle....but forgot to switch profile when fly with 3s with throttle scaled to 75% in this video...
