Here is the improved version of my Nanolongrange FPV drone frame. The .stl file for 3d printing the frame can be downloaded for free on Thingiverse: https://www.thingiverse.com/thing:4818009 I'm very happy with the results. Next upgrades will focus on the FPV system (different antennas and new RX module). I will also test 21700 batteries and the Insta360 Go 2 on this frame.

Gemfan SL5125 5" sub250g props (1 min 21 sec)

Gemfan's SL5125 features an innovative hub design that's compatible with both conventional 5mm and T-mount 1.5mm style shaft motors. I'm using it on my 5" sub 250g build on Brotherhobby Avenger 2004 motors with 3150kv. Attention, you should use longer screws than the included ones! Due to there great power screws will become loose and result in a crash.

With all the rules restricting fun with drones it's about time to go bigger and lighter. Here is my take on a 5" FPV drone. Currently I'm under 236 grams using a BetaFPV SMO4k and a small Tattu 4s 450mAh Lipo. However, I'm planing on switching to Gaoneng 3s 1100mAh (130C). The frame is a Gatehunter X by Dave_C_FPV, motors are 2004 3150kv by Brotherhobby.
