International Race Day 2022

The day has arrived for BTW – International Race Day 2022

We just about snuck in the first ever BIRD in 2020 before Covid hit, so after being pandemic-ed off for a year we are finally back with a bang in 2022!!!

This year BIRD is hosted at BOM, an amazing science and art exhibition and design space in the heart of Birmingham. They have been super supportive and generous with their time and resource to help make this event special.

We had to wait till the exhibition space was closed for the day before we could start setting up. This meant being super organised and having everyone ready to go with a plan of where each item needed to be. All the gates and equipment had been dropped off earlier in the day so we could get going as soon as we were allowed. There were a few technical challenges like getting power to all the gates and PA equipment and lights that needed them. But we actually managed to set up and get flying within 1 hour 30 mins, which was only a little behind schedule and something Im very proud of for such a complex event.

We had a pilots lounge set up with lots of tables, power cables and chairs. Reynolds bought along his 4 way video receiver and projector and cast it up large on the wall so everyone could see the racing. The lounge was up and away from the cafe and the racing which was good to allow a quieter space to get kit ready, but meant the cafe and race area was empty for some time. This was a quirk of the venue space we had use of.

The venue itself was super interesting to fly. Split over 2 levels, with a balcony mezzanine, I was adamant we would use both levels. I wanted to take advantage of the huge atrium height to add dimension to the track where most clubs just have gates standing on the floor. This made for a very interesting flying style as there were some very fast a flowing bits leading to some technical and tricky sections that caught some people out. One of the trickiest parts was flying along the balcony railing towards a wall and then popping up and thru a gate on top in a very sharp manoeuvre. If you didn’t have good control of your whoop this bit proved challenging.

The sponsors really pushed the boat out and gave the event a lot of support. Both Beta FPV and Drone Junkie supplied gates which we set up in a quad arrangement with bright lights to illuminate them. They looked incredible in the goggles and to watch as the whoops span in and out of them. The BetaFPV gates also had awesome scrolling LED lights threaded into the centre which I was worried would catch whoops like a flytrap, but no one got hung up on them which was good. The batteries were not designed to last the whole night, so I had a power source for them. With this, they worked perfectly and looked amazing!

I made a big deal about this event being about the visual extravaganza and party for the community. Its a hobby what is not as serious at the 5 inch drones that go racing on which people spend vast sums of money. You CAN spend a lot on a whoop setup, but just a starter bundle like BetaFPV Cetus range is relatively competitive. You may not be the fastest or lightest (altho you will be close) your race position will depend more on your skill as a pilot and luck on the track. I mean, its not every day races where you’ll have a giraffe flip you right side up after a crash, or a helpful scooby doo scoop you out of a tricky spot!

Being less serious, BIRD2022 encouraged dressing up in onesies with a bonus second off your qualifying times. This meant that not only was the event a whole lot more fun, but if anyone got grumpy and started mouthing off, everyone would just laugh at the angry smurf getting in a flap about something that is not meant to be taken seriously. Of course, the racers are alway looking to prove who is fastest and I knew that they wouldn’t be able to resist an easy 1 second off their times which meant pretty much everyone turned up in dress up! I wish I had had the foresight to arrange a mass photo of us all in costume, but organising a race is just so busy, it slipped my mind.

The other incentive that was offered was to include LED’s on the frame of your whoop. This is to make them easier to see flying around a dark room. It meant photos would get light streaks in them and knowing who landed in what position was easier. Again, racers were not about to give up a whole second off their qualifying times so about 90% of the whoops had some sort of LED lights installed. It made watching them zipping around a whole lot more fun. Martian McFly even went so far as to use them as an advantage – his were so bright that anyone following him would have a sunburst effect in their goggles! Not sure it worked but it was another interesting dynamic to the event. My hope is that now they are installed, the LEDs will remain on the frames and be seen more at future events.

LED’s are critical to the events – they illuminate the gates and make it so much more special to fly thru. Its literally like designing your own computer game like TRON and zooming around all the colours! They make the video recorded from the onboard cameras amazing so we tried to use as many as possible. One of the new features this year was a Hype-Gate. This was made from 2 sheets of plastic roofing wrapped into a tunnel and screwed to a wooden frame. It used lengths of programmable LEDs so a scrolling effect could make it look like the tunnel shot the whoops into hyperspace!!! It was a big success, hung between 2 doorways to allow passage beneath to the toilets at the venue. It meant safe access to the toilets so no one got hit in the head by a whoop and it just looked awesome! 

The other interesting feature that was a little more controversial was the moving gate. This was a pair of gates hung at each end of a baton of wood, that slowly rotated under a mirror-ball motor. It worked perfectly (for something that was untested) and rotated at exactly the right speed between slow enough to fly thru, but fast enough that you needed to chase it a little to be interesting. Again this was in the pursuit of interest and fun because any racer can build muscle memory around a track, but this would always be different when you arrive there forcing new flight lines each time.

The racing itself was amazing! Jaggers brought along his LapRF timing system which I operated from my phone. I used this with its stand alone timing app and a spreadsheet to record the times. It worked fine, but not very professional and a lot of time to copy out the times from qualifying. It did allow me the flexibility to adjust the times recorded if there was a hardware error and include the bonuses for pilots wearing a Onesie and sporting LEDs on their quads which was useful.

As expected, the top racers took a few laps in practice to get their eye in and then they were very competitive. I wanted the track to be about 45 seconds long for slow-intermediate pilots so they would get at least 2-3 laps before batteries were toast. Indeed during practice, by sheer luck, the laps were about 40-60 seconds but soon dropped to the mid 30’s as people got their eye in.

During the qualifying sessions the best times dropped even further. 30 seconds to get around seemed to be easy now people knew the track and the best time of the night was 23.2 seconds!!!!

Once qualifying times were posted, we had our lineup for the final race. It was going to be a spectacular final with all pilots battling for the prestige of being first in their group. I was lucky enough to scrape into the Group B finals and after a frantic race, where I lost video in the stairwell, I made 7th position overall. The Group A final race was intense. These chaps were top of their game and absolutely shredding it around the track. Martian McFly unfortunately didn’t get off the grid on the buzzer so lost 5-10 seconds sorting his quad arming out before pulling away. There was no coming back from that, one of the unlucky parts of racing. Carpy was outta there, he was just gone leaving everyone to eat his prop wash. Smooth and fast, he easily took First. But the battle for 2nd was between AntiHype and Carb. After a quick takeoff AntiHype was leading the pack and there looked like nothing could stop him. Only a few bobbles allowed carb to keep up until a bit too much power put Antihype just to high for the tunnel gate and he hit the wall. This crash sent him cartwheeling down the stairwell to where no video could escape. After a rescue from a helpful track marshal, he was back up and flying and would have lost 2nd place, but for Carb forgetting to crash gate and going for another lap. This just allowed Antihype to keep 2nd place

Lots of organisation has gone into getting today ready to make it as good as it can possibly be. 

  • Gates, LEDs and track features provided by Jaggers and Reynolds
  • Venue, food and drink hosted, cooked and supplied by BOM
  • Prizes graciously donated and subsidised by Beta FPV and Drone Junkie
  • Lights and sound system provided by my brother
  • Video display and broadcast of the event by AntiHype
  • And of course, help setting up and transporting everything from around the UK by all of the above.

The help and support from the whole community was amazing and made the event super special so thank you from the bottom of our hearts for your involvement and effort!

Admiral Rodney’s Pillar

We rose slowly, enjoying the last of the “best room” hotel luxury. We also made the most of the large welsh breakfast which was amazing – all the food had been amazing actually.

It had been a mixed holiday but definitely improved through the week. It was time to head home and while we were feeling tired, we also wanted to go for a walk to enjoy the beautiful weather and scenery some more.

Date Night

We had had enough and we left.

I packed up the van with all our stuff and retrieved all my cooking gear from the kitchen (we hadn’t trusted the supplied utensils). Left it in better condition that we found it, and rolled out in search of some holiday for our holiday.

Whoop Prep

Covid has pretty much killed off all social groups, including the BTW (Birmingham Tiny Whoopers). We were only loosely a micro drone club to begin with, focussing more on the quirky beer and flabber-gobbing about the world, but we did get some flying in. We even put on an AWESOME race event at (RIP) Kongs Birmingham. This brought me to the fringes of the organised Whoopers who engage on a country wide level to put on events and races.

New FPV Goggles

I’ve been introduced to a technological out of body experience that is nothing like anyone in the preceding million years of human evolution could possibly have imagined. Until only recently, literally flying around your garden has been the domain of mother nature and her feathery offspring. But now, with the advent of microprocessors, seemingly precognitive programming, industrialisation and mass production of incredibly finely engineered components and technology, has it been made possible.

My little Tiny Whoop drone has been abused for the last 2 years flying (and crashing) around the house on a regular basis. Its possible to fly around outside, but its range is limited, controls twitchy and power mediocre against any sort of winds. I have therefore expanded my little fleet with the addition of the Diatone GT349 HD – a 3 inch (referring to the diameter of the propellers) quadcopter that last year was “The Fasted Ready Built Quad You Can Buy”. I figured, I may as well buy something ridiculous if I’m going to get involved at all. Other than that, its sub 250g flying weight means it comes under the laws governing drones and means I don’t need a special licence to fly it.

As promised, it’s ludicrously fast and has taken several weeks of practice on the simulator to be even remotely competent at piloting this little ripper. Of course, I’ve crashed it, but it’s robust and has taken a few knocks impressively. But, what I have noticed, is that my video feed is TERRIBLE when compared to any of the pilots showcasing their flying on YouTube. While in all cases, the crashes are my fault, invariably, the video feed has contributed to the calamity. Also, I own a good controller, nowI own a good drone, I should have goggles to match so i can continue to evolve this hobby that has hooked me in.

Up until now, I’ve been using some Eachine EV800 goggles which were very cheap and very basic box goggles. Literally, a screen in a box that you put on your face. It strains your eyes a bit because the screen is so close to your eyes, so lots of other people go for diopter screen goggles that have a screen and lens per eye which are much better. When I was just getting into the hobby, I didn’t want to spend too much so the diopter goggles I could get had teeny tiny screen sizes, like looking at your phone screen across the room. So for the money, the box goggles were more screen size per £££ and did the job just fine, especially because I was only flying indoors and never more than 20m away from myself.

But this drone is in another league, it’s RI-DONK-ULOUSLY fast so it needs a large area to really enjoy its full capacity. It also has a HD camera that records to an onboard SD card. The camera is really quite good when you look back at the recordings, plenty good enough for showing off my stylish crashes on YouTube! But when the image is reduced to STD definition and sent back to the goggles over analogue transmission, and then displayed in my crappy goggles, its like running thru the woods with tracing paper over your eyes – you are definitely going to crash.

So I bit the financial bullet and bought the Skyzone 04X goggles. An (almost) top of the range set of diopter goggles with OLED screens and an impressive receiver module that has impressed many of the FPV community leaders. I was eager to try them out, but the changeable April/May weather was not allowing me to get out there…Literally, I had the batteries charging because it was nice and sunny, and as soon as they were done, it was already raining. 

Eventually, I got a chance and experienced what my money had bought me. The contrast and colours were fantastic, thanks to the OLED screens, and they looked as physically large as the box goggles I had been wearing but without the eye strain. They were everything I had hoped for as I took off and swooped around. The clarity was incredible too. I could see the power cables leading up to the house and could easily avoid them. With the box goggles, I just had to remember to stay low enough and occasionally, I had hit them because I just couldn’t see them.

But midway into my second flight something unexpected and critical happened – the video went all skwoofy (its the most accurate word I can think of to describe what happened – you get it) I just about managed to keep it in the air and not lose it until the video came back and I could come in and land. I tried again and about 1 min into another flight the same thing happened, but this time I was REALLY high up and travelling fast towards the houses on my row. If I had tried to keep flying it would have gone way out of visual sight in seconds, probably into the woods which would have made finding it a ballache. So I had to cut power and let it fall. Luckily it landed in a soft grassy field just in front of the house and there was zero damage.

This is very annoying since I just spent so much on these goggles. I’m not sure why this happened, but I have a hunch based on absolutely zero experience and knowledge of radio systems… so its about as accurate as asking the internet, which is my only other option…. The receiver module picks up the video radio waves and displayed them on the screen. Back in the day, receivers only had one aerial, so if you flew far out or behind some trees, the signal would be disrupted and you’d get static or a break up in your video feed. Manufacturers decided that 2 aerials would be 100% better than 1 so came up with a receiver technology called Diversity, where the signals from 2 aerials would be analysed and the best signal would be displayed. This definitely improved things, but you get a white flash as the module switches between signals, which is a bit distracting. Now another type of receiver has been developed and produced by Immersion RC called Rapid Fire and now Skyzone called Steadyview or Rapidmix which takes the best bits of both signals and blends them together to give the clearest image available. This is part of the reason I bought the Sky04X goggles, for this module as its currently the leading technology and would give me the best image possible, with the ability to change the module in future if better tech was invented.

My completely unfounded hunch is that because the Steadyview module is blending signals, both the antenna need to be picking up exactly the same radiowaves at the same time for them to be displayed correctly. If one aerial is slightly longer or positioned differently, it might not be receiving information in phase with the other and this might be confusing the module. My reason for this thinking is that when the image when skwoofy (totally a word thats going to catch on) there was still sort of a usable image there, but its was scrolling up and down the screen and very fuzzy. This makes me think that signal was being received, but not processed correctly….. What do you think? I wish I had an SD card in the goggles recording the feed, but alas, I was unprepared for a brand new set of goggles to do something strange.

I’ve not given up on them however, the picture quality is fantastic and they are vastly better goggles overall. I’ve since updated the goggles and module firmware to the latest release and will test this out to see if the same thing happens. Hopefully this will fix the issue.
