After trying a few different motors combinations, I end up settling with a set of old school T-Motor 1806 2300kv motors that came off a Vortex 285. Even though the 1407 2722kv motor is lighter it did not have enough punch to really move the quad. The 1806 motors had no problems turn a 3 blade HQ V1S 5X4.5X3 5" Props, in fact the motor came down cool after 6 minutes on an 850mah 4s pack. Before going to a larger 1806 motor I did try using a DYS 1407 3600kv motor and I did like the extra KV but the motors were hotter than I would like.
I also flew a friends Floss with Hyperlite 2205 2500KV motor and it did not seem to have a huge difference in performance over the 1806 motors so that is why I will keep using what I have.
I am a big fan of Gemfan Flash 5152 props and the 1806 motors did a pretty go job turning them, but once you start going past 60 percent throttle your efficiency really starts to tank. Another great feature I like about these props is how super quiet it is. I flew few packs with these props and I really like how it felt and the motors was only warm. However, the 850mah battery takes a bit of a beating. Then I decided to give the HQ V1S 5x4x3 5" Props a try because it was much lighter than the Gemfan Flash. With the HQ props the quad dropped about 8 grams, so now it weighs only 194g. Without changing the PIDs and only the props, the HQ props felt pretty good and simialr to the Gemfan Flash. With smaller props, lower pitch, and weight I was able to get longer flight times and less strain on the 850mah lipo. By changing to HQ props, it is a win-win situation.
Side note, I need to work on the positioning of the crossfire antenna. I might go back to the standard antenna because it more flexible in term on how to run it.

you are going to be soooo disappointed by those motors.
Cool setup with the motor selection! You might want to try T5051C DAL Cyclones, the crystal thin ones, on this build. As long as the amp draw isn't too much for your batteries, you might find they feel good on a lighter build because they spin up and down really fast.
For your antenna options, you can get a TBS Crossfire Micro dipole antenna. It's flexible, and then you can mount it in more creative ways, especially if you aren't necessarily pushing range.
Why swap the di-pole from the vTx03 for the heavier omni/3-D printed plastic bracket?
After switching a few of my smaller 2.5 and 3 inch quads di-pole antenna from the vtx03 to the a Realacc UXII Stubby I saw a huge improvement in the video. Since the Realacc UXII Stubby only weighs 1.6grams, that is well worth the video improvement. I did not use a mount for the smaller quads like I did on this build, So the floss did have a little more weight for the 3d printed part. I guess I could have hot glue the Realacc UXII Stubby to the frame, but a 5" quad should be able to handle the few extra grams. :)

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..

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..

i have a similar build planned. did you drill out thr hglrc f428 to fit m3 hardware?
I used m2 hardware to mount the f428 stack. Take a look at my orginal build for more detailed pictures of the stack: https://rotorbuilds.com/build/13708
