I would like a small brushless drone under 2" but when built them like bat100 etc problem is the quality!?
problem with FC, motor, frame or ALL.... waste of money!
So I was waiting for better brand than Happy Model... and with "traditional" design... means tower board and frame!
I am not following the "trend" like FC: 25,5x25,5 prefere 16x16 or 20x20 tower FC!
Woala Geprc is arriwed with smart16 this year.... but high price!
Anyway BG had promo ordered one to fly other for spare!
Plus have to REbuild and to solve "childrenhood" sick on it!!

Frame

• platform of motor is breakable look this video at 7:41
  https://www.youtube.com/watch?v=FSvcRt7vedY&t=459s
• had to do stronger platform of motor with small double carbon plate
• important any landing gird bcus less the force on end of arm when crush happen!
  (( it is ugly but useful anyway who could see that on the sky over 30 meters far? :) ))

Motor

• soft glue inside cooper roll
• hard glue under the shaft
• using longest screw M1,4x4mm!

FC

• replace plastic screw into metal
• install Beeper and receiver on it
• solder xt30 plug with capacitor

basically it is 36gramm plus receiver (Xm+) etc sum around 38-40g?
with my extra additional.... the weight is 42/43/44gramm but I feel it can be more safety!

2023 November replaced:

1. receiver from Xm+ into ELRS (-2,5gramm)
2. motors from Geprc 2S-0803/11000KV into HappyModel 2S-1102/13500KV (+2,5gramm)
3. motors from Geprc 2S-0803/11000KV into Uruav/HappyModel 3S-1102/9000KV (+2,5gramm)

Weight: 44g
