The de Havilland DH.88 Comet is a British two-seat, twin-engined aircraft built by the de Havilland Aircraft Company. It was developed specifically to participate in the 1934 England-Australia MacRobertson Air Race from the United Kingdom to Australia.
Development of the DH.88 Comet was initiated at the behest of British aviation pioneer Geoffrey de Havilland, along with the support of de Havilland's board, being keen to garner prestige from producing the victorious aircraft as well as to gain from the research involved in producing it. The Comet was designed by A. E. Hagg around the specific requirements of the race; Hagg produced an innovative design in the form of a stressed-skin cantilever monoplane, complete with an enclosed cockpit, retractable undercarriage, landing flaps, and variable-pitch propellers.
Three Comets were produced for the race, all for private owners at the discounted price of £5,000 per aircraft. The aircraft underwent a rapid development cycle, performing its maiden flight only six weeks prior to the race. Comet G-ACSS Grosvenor House emerged as the winner. Two further examples were later built. The Comet went on to establish a multitude of aviation records, both during the race and in its aftermath, as well as participating in further races. Several examples were bought and evaluated by national governments, typically as mail planes. Two Comets, G-ACSS and G-ACSP, survived into preservation, while a number of full-scale replicas have also been constructed.

This is an absolutely fantastic model, and flown superbly!! Very beautiful flight demonstration. Plenty of power.

[@zolatanaffa87]

one of the most famous and iconic British planes of the 30s. If, as I read in the posts below, it is the same model that was built 20 years ago I would say that the materials are excellent. By heart the original propellers were larger but even those were two-bladed, so here too, a well-rounded historicity! Thanks Dom for sharing this video. See you in the next shootings. Cheers!

[@rick7884]

[@cal-native]

With such high aspect ratio wings I'm wondering if there isn't more than a little adverse yaw he's dealing with? Do his turns require some coordinated rudder, in other words?

[@jeronimo20242]

nice!!!

[@Hunter_S-fr4ns]

Wow!!! 👍

[@peterofenbaeck405]

This is a very nice plane. All the more the tiny propellers bother me. Would it be possible to install reduction gears and thus use larger propellers, which would give the model greater authenticity even when stationary?

[@leighthetwinotterflyerjone9460]

Is this a replacement plane or steves original because if it is the original then he has well got his moneys worth as i remember seeing this flying in the 90s what a well built model

[@sparrow082]

It needs aileron differential, that usually does a better job eliminating the adverse yaw. I think it works better than throttle differential or Rudder cross-coordination.

Just to say there was a very strong cross wind that day. I was there. it looked superb!

[@makemyday1477]

So at what point will the FAA step in and require an airworthiness certificate and license to fly RC planes over a certain size?

[@EssentialRC]

They are very unlikely to in the UK I think because they control the US airspace but the CAA here in the UK already have a scheme in place run by the Large Model Association for any RC aircraft over 20KG.

[@FlyingRob1]

Sehr schönes Modell, aber die viel zu kleinen Luftschrauben lassen es wie Spielzeug aussehen. Auch der Klang ist grottig. Ein Getriebe brächte etwas Abhilfe.

Can anyone tell me why such a large aircraft with huge prop cones has such tiny propellers ?

[@EssentialRC]

Optimum propellors for the engines used. Simple as that really.

Optimum props for the engines used.

[@mikesmicroshop4385]

@@EssentialRC I was not commenting on the fact that it is underpowered, only the fact that the props make it look goofy as they are so small for the plain that it looks ridiculous! I have and always will feel that part of making a scale replica includes proper power plant to support the proper sized Prop! Putting ridiculously undersized Props on a replica detracts from the overall look of a plane that it to me is unacceptable especially if the event is juried on accuracy of the replica, and even still it just masivally detracts from the overall look. That is my opinion and I will stick to it!!!

[@EssentialRC]

@@mikesmicroshop4385 Cor blimey, OK. Calm down. Calm down. It's a common problem with large RC aircraft sadly. They optimum props are relatively small compared to the full size. Don't think there is anything they can do about that. 99% of folks don't notice it especially when they are spinning.

[@maxshep2829]

A lot of them have scale 'display props' that they put on when the model is on display or being judged, in the air it doesn't matter as usually the things are spinning that fast that most people don't notice =P

I would build it a little bigger and get in

[@BaquePhotography]

I'm so glad all these giant RC aircraft are made out of foam. I mean if they were made of anything else it would be practically criminal to fly over people. And I'm so happy that everyone who fly's these has to go to hundred of hours of training to be able to fly these giant machines. And the insurance they have to carry in case they mame some kids or something. I mean what kind of person would put almost a full size airplane in the air with only throttle and control surfaces control, you'd have to be a narcissus that doesn't care about the lives or property of other people. So I'm so glad there made of lightweight cant hurt anybody foam.

[@EssentialRC]

When we fly RC we don't fly over people. Why would you assume we do that? Utterly clueless.

[@BaquePhotography]

@@EssentialRC Dude theirs tons of people in those videos, radios never malfunction, push rods don't break? Your the one who's utterly clueless.

@@BaquePhotography That's got nothing to do with my reply. You said 'fly over people'. We don't fly over people. You seem utterly clueless about how to have a conversation buddy.

Look you know what im talking about, your flying something that can cause serious bodily harm and your just blase about all the dangers. That thing could lose radio control and kill people. You know this but evidently don't care. I hope to God no one has to read this comment in court after a mishap. I'm done.

[@EssentialRC]

@@BaquePhotography There is very little risk of these RC aircraft hurting someone because they are flown at public events where there are strict safety guidelines in place for the pilots to follow. I'm not the clueless one here buddy. Correct. You are done.

[@DoRC]

At that point I think I'd just build a full size plane and actually fly it.

[@EssentialRC]

If you do please let me come along and film it because building and flying an actual passenger carrying aircraft is almost the same as building an RC one isn't it.

[@DoRC]

@@EssentialRC I built a full size KR2 (grew up on a private airport) with my dad when I was young and honestly, other than being a lot more careful the process is pretty similar. Especially when the model gets as big as this one. Obviously there are differences but the basics are the same.

[@markg55]

I love how Every. Single. Video. of a large scale RC plane has some variation of this exact comment, seemingly posted by someone who thinks they've had an original thought. It's a totally different hobby, though. Lots of people who fly RC fly full size too. It's like telling someone who gets into running that they should just ride a bike instead.

[@maxshep2829]

Pfffttt... The canopy isn't right, the props are too small, it's underpowered, the exhaust doesn't sound correct, it's a risk to the spectators, the red paint isn't quite exactly the correct shade... And it's a toy for the super rich! Terrible! Simply unacceptable! Haha, i'm only joking of course... Cor, that's a biggun! And absolutely gorgeous, both in the air and and on the ground... Exactly like the original! And flown beautifully as well, the half-scale pilot has been trained well! Cheers for sharing it with us, now i wouldn't mind seeing this one fly in person sometime =)

What happens during a mechanical or stuctural failure of this "large" model airplane flying such close proximity to spectators? The F.A.A. would never allow this to happen, so why is this size model allowed? Tis a catastrophe waiting to happen.

[@EssentialRC]

Oh here we go again. Utterly clueless and making assumptions. It's not close. The event operates under strict safety guidelines and the model aircraft is reviewed during its construction and first 2 hours flying by qualified engineers.

[@leaderspeakusa]

@@EssentialRC Utterly clueless? I voiced a legitimate concern. Just because a "model" is built under strict safety guidelines and the model aircraft is reviewed during construction is NO guarantee it won't fail at some part/point. If your position were 100% foolproof - then, NO RC would crash/fall apart or run in to something - not to mention its very physical flight performance is dictated by radio wave - which has a failure rate also. Instead of mocking my concern - perhaps you ought to address it with compassion and scholarly concern. FYI. Just ask the engineers responsible for the 737 MAX.

[@EssentialRC]

You didn't state a concern. You are scare mongering. "Tis a catastrophe waiting to happen." Large RC model models have been around a long time. The technology involved improves all the time, the safety measures are review/improved regularly and in this case the model aircraft was built by a very experienced engineer. Your logic applies to any vehicle operating anywhere not just RC planes. If you are that worried best you stay inside and don't go out the front door. Yes, you are clueless regarding this unless you ACTUALLY are familiar with what is involved with a project like this. There are plenty of RC aircraft in the US that are this size or larger. Just use google buddy.

[@leaderspeakusa]

@@EssentialRC LOL Kind of touchy aren't we? I'm an Amateur Radio Operator whom have seen the best electrical engineers electrocute themselves; hiked the 2,175 mile Appalachian Trail (twice) and seen experienced hikers die of hypothermia; bicycled from the Atlantic to the Pacific and seen veteran Olympic athletic long distance cyclist hit and killed by others because their equipment failed at the wrong time.
