@PSEM_Portugal Sounds familiar 😉

Our most recent model had it’s starting point at the study of the previous prototypes. An innovative feature is the presence of 2 channels above the cockpit that allow for the creation of a low pressure, which reduces the effective weight and the aerodynamic resistance.

@TeamBirdGP @rgshwGreenpower @greenpower_team @rgshw That'll depend on what age rating the simulator has.

@Stealth_Racing @rgshwGreenpower @greenpower_team @rgshw But does the drivers behind touch the ground 🤷🏼‍♂️

Who did it better??? Thanks @TeamBirdGP for the video, the cone placement would have been an even bigger nightmare without it! @greenpower_team @rgshw

@TeamBirdGP @rgshwGreenpower @greenpower_team @rgshw Don't worry, I'm sure they will put in a 'floor falling off' option in for my car in the menu somewhere....

@Stealth_Racing @rgshwGreenpower @greenpower_team @rgshw

To all of my rivals, if I do race again, don't worry I still have plenty of tricks up my sleeve! Any questions, happy to answer them. dropbox.com/s/jbyqjdsyu5od…

A bit of light entertainment for you all.... I thought I would share my report that I did for my university final year. It delves more into the aerodynamics of Stealth III and compares different designs in range of yaw angles with all of the data you can imagine!

@TeamBirdGP @PSEM_Portugal Stealth 2, low profile and simple. 3 not too far behind.

@Stealth_Racing @PSEM_Portugal But which design was your fav?

The superman-steering is a counterintuitive system. In our car, when pushing the left lever and pulling the right one it turns left, which is the opposite to what happens in bicycles. Despite being odd, this system assured the 2nd place in one of the races from last season!

@TeamBirdGP @PSEM_Portugal Can't tell, but is that a bell crank or a rigid arm coming out of the kingpost on each side? Seems an odd use of the rose joints. Lots of ways of making the steering turn, every car of mine had a different steering system but always turned intuitively ie push left turn right.

@PSEM_Portugal Is that intentional or did you get the links the wrong way round..? If you swapped the link connection and pivot point it would turn traditionally like a bike 🤔 (ps we did something similar with firebird and it was impossible for anyone to drive till we fixed it)

@rgshwGreenpower @greenpower_team @rgshw Something to do with the book it's sitting on.....? 😲

What’s going on here? 🤔 Wrong answers only... @greenpower_team @rgshw

@PSEM_Portugal @TeamBirdGP @pod_movement @cliveallen92 Speaking of low noses, back in the day when I didn't know better and slammed the whole car low. Helmet almost below top of the 16" wheels. Ultimately you tune the nose to work with the rest of the body and with no need for downforce, flat-ish underside works best.

@TeamBirdGP @Stealth_Racing @pod_movement @cliveallen92 In aerodynamic terms: you're right, and that's why GP19's bodywork looks so different from GP17's In meme terms: don't worry, GP17 was designed as an amphibious vehicle 😂

@Stealth_Racing @pod_movement @cliveallen92 Alignment is a big factor as well. Tracking gauges are something worth studying, wouldn't you say @TeamBirdGP ? 😉

@TeamBirdGP @PSEM_Portugal @pod_movement @cliveallen92 How nice of you to post a picture with our car in front! The heavyweight vs some featherweights....

@PSEM_Portugal @Stealth_Racing @pod_movement @cliveallen92 More tech facts, firebird weighs no more than 105kg race weight (with driver and all the tape. But yes alignments help to. Here’s what we used for tracking BlueBird back in 2017 (whilst Gav figures out the championship table on my laptop) and a nice photo from later that day

@pod_movement @cliveallen92 @PSEM_Portugal It's not all about aero though.... Stealth II was 7.5 N at 40mph, but still was relatively 'slow' because of its weight and draggy small wheels. S3 had slightly higher drag but did use the bigger wheels which gave more speed in return.

@cliveallen92 @PSEM_Portugal Wow, no wonder you are so far in front of us POD-SIX would be pushing double that, at that speed 😩😩😩

The Aerodynamic Department studies the best design to create a model with the lowest aerodynamic resistance possible!!

@cliveallen92 @PSEM_Portugal @pod_movement So now that's more like it 😉 Full car, wheels, roll bar?

@PSEM_Portugal @pod_movement The nose of the car might be a bit high pushing to much air underneath, for reference Firebird drag is 10N at 38mph

@TeamBirdGP @greenpower_team @RenishawGP @pod_movement @PSEM_Portugal @Crazydiamond_gp Filling up all the holes you drilled for the final last year. I told you 86 was too many!

The fibreglass is out, that means something’s happening 🤔 but what? @greenpower_team @RenishawGP @pod_movement @PSEM_Portugal @Crazydiamond_gp @Stealth_Racing

@pod_movement @TeamBirdGP @Greenpowertrust @RenishawGP @DresselRacing @Kestrel_GPT @JLRDriven Wasn't there when I looked 😉

@TeamBirdGP @Greenpowertrust @RenishawGP @Stealth_Racing @DresselRacing @Kestrel_GPT @JLRDriven Too late then! oh well have a good winter 🙄🙄

New year new toy 👀 @Greenpowertrust @RenishawGP @Stealth_Racing @DresselRacing @Kestrel_GPT @JLRDriven

@TeamBirdGP @BhasvicRacing @Greenpowertrust Sorry, that red brake light of a livery, that doesn't seem to be turning on and off, are you sure it's plugged in?

@Stealth_Racing @BhasvicRacing @Greenpowertrust Scruteneir stealth out to get us? 🤔

@TeamBirdGP you hear that? You’ll lap us only 5 times this race! 👊🏻 @Greenpowertrust

@TeamBirdGP @BhasvicRacing @Greenpowertrust On track, I'm letting them off for this year. Off track, who knows what can happen in the paddock...

@BhasvicRacing @Stealth_Racing @Greenpowertrust I wish

@TeamBirdGP @BhasvicRacing @Greenpowertrust 38 kg.... Rookie numbers 😉

@BhasvicRacing @Greenpowertrust Sounds like fighting talk. Shall we turn that into a percentage based weight reduction? Base car weight (no batteries or amputated driver) is down 4.9%. Let’s settle this at Silverstone 😉

@HorsfallRacing @Greenpowertrust @pod_movement @SgaRusko @JJDyson @chip_giles @mattbeee @HugoTLopes @Mykesbass @mjb258 @CAUC_SHS @CullimoreRacing @Kestrel_GPT Why isn't there an option for everything?

@Greenpowertrust looking at you guys 👀@pod_movement @SgaRusko @JJDyson @chip_giles @mattbeee @HugoTLopes @Mykesbass @mjb258 @CAUC_SHS @CullimoreRacing @Stealth_Racing @Kestrel_GPT If I've forgotten some Tag others!

Having only just recovered from writing about our first taste of @Greenpowertrust in 2002, I feel like it would be unfair to expect to you all to read about the 12 or so seasons that followed from there on. So what do you want to see?

@TeamBirdGP @Greenpowertrust Obviously hybrid theory, lowest car number and more 1s than I can count....

@Greenpowertrust What would the best car be? 🤔

What could be more entertaining than whiling away the hours playing Greenpower Top Trumps?
