Finally got to fly a quick maiden with this build around my complex. It moves! Video will be up soon. I still have to setup the GPS unit and recently the buzzer has just started a sustained beep whenever power is applied. As soon as I figure out those issues I will try some medium range flights and see how long of a flight I can get on both the 650mah and 1100mah batteries.



UPDATE 5-1-20: After quick test flights in super windy conditions with the 1100mah packs I saw no major difference in flight times to the 650mah packs. The low C rating means that energy density is probably close to even. Ive also decided that the 1505 motors are just too much for 3s and the design of this quad. Ive switched to 1404 3800kv motors and am very happy with the results. The quad just feels so much smoother now. Im going to try some 850mah gnb packs that should be showing up today as well.

I am building up another sub250g 4in with the 1505 motors with the specfic idea of running 4s packs and eventually a lofat or naked gopro setup. Stick around and this build will be posted soon enough. That rig is based on the MOD-L by LeDroneClub, but ive tweaked the chassis plates and redesigned the arms to be a bit burlier (upped the width a couple mm, gone from 3 to 4mm carbon.) On this build I think the HQ 4020-3 are going to be the ideal option paired with a 650-850 4s pack. This one is going to be a freestyle flippy flopper so response and low end will be key!

In the test last flight I disarmed a bit further from the ground than I thought I was and ended up destroying the buzzer battery and popping the gps unit out of the mount and straight to the moon because I could not find it. New gps unit will be mounted to the battery strap and for now I replaced the 30mah buzzer battery with a 150mah random pack I had from a cheapy toy whoop from forever ago.

If I find the time Im going to try to do a big test day soon. That day will include battery tests: 650mah HV 3s - 1100mah HV 3s - 850mah 3s as well as testing all the props Ive been collecting: HQ 4025-2 - HQ 4020-3 - Gemfan 4023-3 - Gemfan 4024-2. Preliminary findings about props though - All the options feel great in hand. HQ feel a bit stiffer and maybe just a touch higher manufacturing quality. One wish for the HQ props is that they had a wider range or color selection cuz you know I love some bright azz colors, particularly on smaller quads.

Besides getting the quad all set up ive been learning and adjusting to new goggles and vrx units, as Id really like to get clean audio working for commentary and ambient noise so that I can represent what each prop sounds like to me. Im also refining my mirrorless (vlogging?) camera setup with a stereo mic so that videos can feature hopefully a faithful representation of what each prop setup sounds like in person. Regardless these low-Pitch+weight+kv setups are really quiet anyways so im not really sure how important ambient audio will be to a review video. Let me know if this is important to you and worth my time to refine and figure out.

Anyways heres to hoping I get time to fly and shoot and edit something good for yall.

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
