Starting a "Mini-Series" on potentially Great video transmitters (VTXs) for Micro Quad Builds. This is the first in that mini-series. Recently purchased the TBS Unify Pro Race 2 VTX because of TBS reputation for great quality VTXs, MMCX Connector, Audio Input Pad (allows for external microphone connection for audio in earbud while flying and also on DVR video), small size, and Only 4 grams! Reviewed features, physical size dimensions, and concluded with two flights (side-by-side) on both the minimum and maximum output power settings. What do you think of both the video and audio quality? Enjoy!

Superhero Quad! Iron Man Wizard! This is our 2nd video in the series HOW TO BUILD FPV 5 INCH RACE DRONE. In this video, we cover both the BetaFlight and BlHeli setups of our Eachine Wizard X220 5 Inch Race Drone after helping it shed 20% of its original weight in Part1 of this video series. We step through each of the applicable Tabs of Betafliight, use BlHeli32 Suite to “Play Some Music” with our Airbot ORI32 4 in 1 ESC, and conclude the video with our maiden flight! There is a "clickable" hyperlinked Table of Contents in the video description so you can "jump" to any section of the video you're interested in just by clicking on the "Time Stamp" next to the topic. Hope you will find this short 5 Inch Build Tutorial helpful in the construction of your very own FPV Racer! 👍

Decided to begin the New Year with a resolution to help our Eachine Wizard X220 (FrankenWiz) shed some weight! We replace the old, heavy parts with new, upgraded, lighter weight parts and "squash the frame." We start with the frame base plate and work through each step of the build in using speed-enhanced video without sacrificing important build steps.

I am constantly searching for the "best" (and best value) FPV set-up for my flying conditions. I fly primarily proximity in my "rural" yard and around my house at low-altitude while I continue to improve my skills. Every once in awhile, I will venture out into the "open" for more freestyle type flying--right now, I'm mainly flying Micros low altitude around flags and through gates.
Anyway, in pursuit of the "best gear' I currently have an Aomway Omni Directional Clover Leaf on one side of my Aomway Commander V1 Goggles along with a 10dB TrueRC X-Air directional. Thought it might be worth a try a VAS 13dB Pepperbox to see what the difference would be (if it made any difference while flying low-altitude around obstacles).

For those interested, in the below video, we do a side-by-side comparison of the two Right-Hand Circularly Polarized (RHCP) FPV Goggles directional antennae-the TrueRC X-Air versus the Video Aerial Systems (VAS) Pepperbox. We take a look at the manufacturers’ specifications, describe some of the important parameters of the antennae and what those mean to you as an FPV Pilot. We describe our testing methodology and conclude with a flight of approximately 315 meters distance out from our launch pad, purposely flying behind trees to determine when video drops out for each. Wish I had done a long-distance run of both as well! Please let us know your thoughts on these (and any other) antennae you might suggest. If anyone has more experience with the Pepperbox, please post your thoughts on it's pros/cons. Thank you!

Recently, I had to relearn the importance of applying Loctite Threadlocker Blue 242 to motors screws when mounting motors. The reason I had to "relearn" it was because I forgot to apply it when previously replacing a micro motor on my GT R90--I "cut corners." This, in the end, actually cost me both time and money, which if I had been paying attention to begin with, I could have been using that time I spent waiting on a replacement motor to arrive for flying instead. Thought I should demonstrate the importance of Loctite to folks unfamiliar with using it so they may learn from my mistakes. Stay in the air and Happy Flying!

I’ve been flying for almost a year now and have never flown with live audio from my motors until recently. While flying on the Velocidrone Simulator, I noticed how much I enjoyed the sound of the motors and how it was actually helping me with my altitude control and throttle management. Thought, why haven’t I implemented this with my Micro Quads?!? So, after searching, I found a very small “buzzer size” external microphone (with volume control!) to place on my Micro Quad. Pure fun!

A couple weeks ago, we posted our thoughts (and a video) on some stuff we learned from our 2.5 inch FlexRC Ascent X build pertaining to Flight Controllers and ESCs. Today, we continue down that path and discuss what we've learned about 4 different Micro FPV Drone VTX Antennae.

Specifically, we wanted to find out which of the four types of FPV VTX antennae we have actually worked best for proximity flying near & around obstacles (like trees, buildings, etc.). Thought we might as well make a video on it and perhaps others could benefit as well. We compare the standard linear dipole antenna with the circularly polarized Actuna GEM, Foxeer Lollipop V2, and Lumenier AXII antennae. Side-by-side flight video of FPV feeds along with manufacturer spec’s. Slow the video down to 0.25 or 0.5 speed during the flight videos portion by using the "gear"/Settings Icon at the bottom right of the video. This will allow you to make a better comparison of the 4 flight videos simultaneously. In your opinion, which one wins?

This could be the start of something really BIG or TINY (Whoop). The beginnings of our front porch LED Whoop track. Hope to fly it real soon. Wonder if I can make it through the tiny gaps under the porch. What do you think?

Bottom Line: Below I have posted a video doing a side-by-side comparison of two of the most feature-packed Flight Controller and ESC stack combos for Micro FPV Quads. 👍

Why I have done this? – I have just completed a Micro FPV 2.5 inch build and learned a lot of stuff that I thought might be useful to some if I passed it along. In this case, I started out with a different Flight Controller and ESC stack than what I eventually ended up with. My first choice was a stack that had the flight controller and ESC connected by pins. I saw reviews and heard comments from some that they have had problems with this type of arrangement where the “housings” both the “male-type” with the pins and the “female-type” with the receptacles for the pins would physically become disconnected from the boards. So, I thought to alleviate this (because I liked the size, weight, and features of this particular stack), I would apply some epoxy to the joints holding the connectors to the board (as others had done to alleviate this issue). I did not have any problems with this. I did have other issues with the stack, however.

First of all, the ESC in this stack only worked sporadically and erratically and finally ended up burning out a motor (during set-up, not flight!). Secondly, the impact of “normal” unintended landings (i.e. crashes) caused the pin connector’s housings material (I believe it to be plastic) to crack—there would be cracks in the housings. These then led to...Continue Reading

Finally! Got to do the Maiden Flight video on our Micro FPV 2.5 Inch Build!
Meet “Lexi!” Our FlexRC Ascent 2.5-inch build, with on-board Runcam DVR, as she sets sail on her maiden flight. She’s sportin’ the Orange and Green pinstripes.
Maiden Flight was a “Blast!” Check it out below. It’s a Jolly (Roger) Good Time, Savvy? Yo-Ho! How many different “Pirate” things did you see in this video? What did you think about the Onboard Runcam DVR video quality?

Scary Good! After completing our First Build, it was time to give it the ability to fly by configuring it in BetaFlight and setting up the motors and ESCs in BLHeli Suite. In the video below, we do just that in an easy-to-follow, step-by-step BetaFlight 3.5.2 setup for FPV Micro, FlexRC Ascent X 2.5.

HGLRC FC/ESC stack, Runcam Mini FPV DVR, AKK FX3 VTX, Caddx Turbo Micro F2 camera, FRSKY R XSR RX, TMotor/Racerstar 1106/6000kv Motors. Also includes BLHeli Suite motors set-up.

The starting PIDS we used split the difference between those provided to us by Mark Sutter for his 2-Inch FLexRC Ascent X build and those outlined by Albert Kim in his baseline setup for 2-3 inch builds. We also set up three different Rate Profiles on a switch (Race, Practice, and Freestyle), Flight Modes (Angle, Horizon, and Acro), External Buzzer on a switch, Blackbox on a Switch, and Arm/Disarm on a switch. We work through a motor issue which we had and prepare our FlexRC Ascent X 2.5 for its maiden flight! Let us know your thoughts and any recommendations. Happy Flying!

In my last post I mentioned my interest in building a Micro 2.5 inch quad primarily 2S (meeting MultiGP MIcro class specifications) with some 3S.
Below is a video of how I went about choosing each of the components to include the options i was looking at. It includes the parameters for each component I think are important, options for each component, components specifications compared side-by-side with each other and my choice for each component. This stuff may help out others fairly new to builds also.

While I continue to improve flying skills with Velocidrone and Backyard FPV Race Track over time, I now have also become interested in building a Micro-Class 2.5 inch prop "racer-type" quad primarily 2S with some 3S. More info on this relatively soon.

In the meantime, for each of the components listed below, what would be YOUR choice for that component and why? Remember, more of a racer quad than a free-style quad. All comments welcome and appreciated!

Happy Flying!

Got the last Velocidrone track (with flags) down fairly good with "altitude control" and coordinated power turns. The reason I put "altitude control' in quotes is that when you're flying through Race Flags there is no "ceiling" to the gap, so you can actually fly as high as you want. So, the next step in our Journey to Better is to fly this track substituting all Race Gates for the Race Flags. With the gates, it forces me (us--you and me) to maintain our altitude closer to the ground throughout the track even while performing coordinated power turns.

This "gated track' took me "quite some time" before I was able to complete ONE lap! i would say, it took me somewhere between 5-10 hours on and off over a 2-week period before I was able to fly it somewhat comfortably. Slow learner? Maybe, I don't know how long its supposed to take! But Hey!-- that's what this is all about, right?! Improving our flying skills, having fun doing it, and always learning!

The video below shows one lap on the Velocidrone track followed by 2 laps on our Backyard FPV Race Track set up to resemble the Velocidrone track as closely as possible. "Reality flying" this was not easy either! Enjoy!
