HGLRC Arrow - 3” on 4S

I took the motors and guts from my very first build, the 3" IFlight iX3 as shown in the phitos below and put in this much lighter and aerodynamic frame. WOW, what a difference. Even though this stack is a couple years old,, it does a great job. i like the vtx antenna holder but i cut off the receiver antenna holders because i always run my receiver wires off the arms. i found the 850mAh batteries worked best on this size frame...get a good 5-6 min flight time with RPM fltering with AUW of 260g. A 650 mAh battery would put you below 250g. Neon yellow props make this little screamer stand out. i took the old frame and practiced some hydro dipping with a black & red pattern as shown in the picture. It turned out really cool so I'm thinking next freestyle build will have to include this technique

This seems awesome. Next you could move it all into one of the diatone frames (gt r369 seems like the natural choice, but they have other layouts). Would be a similar weight drop, yet again, and only cost you $25.
Not trying to say anything bad about what you have already done, both those frames are great in their own ways. I am also recently into the "nimble-ness upgrades" from dropping big chunks of weight. I have found, despite how small quads are, that aerodynamic changes are also worthwhile, and VERY noticeable.

Thanks Jody. Agree, i would get about 16g weight savings going to that Diatone frame and enough to improve the thrust to weigh ratio. However, i would rather just go with all new components with that frame and focus on the lightest options. i actually started converting my whoops into light, nimble and quick toothpicks and should be posting a 2", 2S 85mm toothpick frame with 803 motors and 5A F4/ESC AIO board weighing 55g soon.

Build a 5" Long Range Drone - Transformer Ultralight

Jun 21, 2021

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
