That coke bottle design was very significant. it was essential for super sonic flight, allowing for smooth airflow around the entire aircraft. because, at supersonic speeds the whole body of the craft creates a pressure wave, instead of individual points of contact ie. (Nose cone/ wing tips), decreasing the cross section through the body of the aircraft means less pressure wave effecting laminar flow. Many a supersonic testbed aircraft was literally rattled to pieces before this break through.

To put it simply, the cross section of the aircraft has to be basically a cone. It has to get bigger as you go from nose to tail. The wasp-waist fuselage is to compensate for the frontal cross section of the wings, same with the narrowing tail being compensation for the tail.

Yes, the 'coke bottle' shape reduces trans-sonic drag by minimizing sudden changes in the cross-sectional area of the plane as the air flows over it from front to back. Hence it is referred to as the 'area rule'. Of course, this thing will have to go about 600 mph faster before the effect kicks in - lol!

Fpv one of those lawn darts 😃

Just FYI, the F-105 was nicknamed "Thud", and was indeed a fighter/bomber. It did have a vulnerability to ground fire, though. Much of the hydraulics were in the belly, and if the Thud got too close to the ground, anybody with an AK-47 could cause the plane to crash. The "coke bottle" waist was developed in the F-102. When that plane was first tested, it wouldn't push through the sonic barrier until engineers gave it that wasp waist. The change allowed easy supersonic flight. Something else you may not know is that supersonic planes have to use an all-flying horizontal stabilizer. Elevators cause major problems once you punch through the sonic barrier.

you guys need to slope that hill!

The F-105 single seat was at the time, the most powerful, heaviest single seat fighter of it's time,. It was nicknamed the thud, which the pilots claimed was the sound it made landing. We also called it the triple threat, it could strafe you, bomb you and if anything was thrown at it, it would fall on you. 62 ft long, 34 ft span, 52,000 lbs . I worked on the main doppler navigation system on the two seat F and G models after the D's were sent back state side, at Korat RTAFB, the 388 Tac Fighter Wing.

Woo! FT!

Landed! Nice looking plane and a good price as well. Looks like a lot of fun! Happy Flying!

Finally I’ve always wanted to see an rc f-105. Granted I can’t even fly it because I’m a noob but it’s still cool to see

Absolutely incredible flying camerawork with the 105 demo...

While at McConnell AFB, Wichita, KS in the EARLY 70s, the base was home to the F105s and the 381st Missile Wing, which is what I was serving with. One day I went on missile alert, the flight line was covered with F105s. When I returned from the missile alert the next day, they were ALL GONE! All went to Vietnam. Another thing about the F105s. When one crashed, two others were going to crash soon after! They always seemed to go done in threes.

Didn't these planes have a tough time with adverse yaw?

That "Coke Bottle" shape is known as an area rule design, also called the Whitcomb area rule and the transonic area rule, was indeed important to keep the airflow laminar and helped greatly from Mach .75 through to 1.2. For some modern examples look at the Citation X, a business jet that can cruise at approx mach .09 even the 747 and A380 use it on the 747's hump, A380s engine cowlings and wing roots. The Thud was a large USAF Mach 2 supersonic "fighter bomber" that spent most of the Vietnam conflict loaded up with bombs dodging Sams and Migs, a few even managed Mig kills with Zuni unguided rockets. From memory the first gen also had some lateral stability issues ... Nice job by the way guys, looks like one fun model 👍

@@neilcaywood3803 After working C-130s, walking up to a Thud, you knew this was a fighter. Everything about it was brute force. I'm six foot and could barely touch the Pitot tube at the very nose. If I was out when they launched, crew chiefs would have me tap the Pitot tube checking for heat. F-4Es had more of a sports car look. 54,000 pounds at takeoff, the nickname Thud was the sound it made landing. 300mph at touchdown. My only fighter, cargo. Choppers and C-5A to finish two enlistments.

Re Andre Reinhardt's comment : Correct, but I will go a little bit further to add to the detail : The process of adding a coke-bottle shape is known as Area Ruling - it was first encountered in WWII by the German designers of the early high performance jets, and their notes and concepts were then developed and fully defined by Dr. Richard T. Whitcomb of NASA, and is sometimes known in aeronautical engineering design as the Whitcomb rule. Essentially the rule works like this - air moving over the body of the aircraft has its drag defined by the total cross sectional area at any point. For the nose cone this is OK, and for the fuselage its also as minimal as possible - but when we get to the wings, the drag coefficient shoots up, as the combined cross-sectional area airflow-on doubles or even triples, depending on the design. The solution, as defined by Area Ruling, is to reduce as far as possible the cross-sectional surface area of the fuselage and wing so that they are as minimal as possible for reduction of drag, but sufficient to retain mechanical strength. The first two American supersonic fighters did not have this at all - the F-100 Super Sabre and F-8 Crusader, the Super Sabre going supersonic by sheer power, and the F-8 having a nascent area ruling around its wing-fuselage junction by very good luck. the first American fighter to truly apply area ruling was the Convair F-102 Delta Dagger, which, with the addition of what became known as Whitcomb Bodies (empty structure which corrected the area ruling) managed at last to go to its maximum speed - without needing more thrust, vindicating the concept. To this day, practically all high speed fighters and jet transports including airliners make use of optimized Whitcomb Area Ruling in their design. The most aesthetically pleasing of these area ruled fighters are - of course ! - the Century Series fighters of the 1950's and 1960's - the F-102, F-104, F-105, F-106. Also the Grumman F-11-F Tiger is another great example. Modern fighters continue the tradition, including the F-16, F-22, MiG-29, Su-27, Su-50, where the modern fighter's Area Ruling is horizontal (flat) rather than the Centuy Series vertical area ruling. For more information , have a look here : en.wikipedia.org/wiki/Area_rule

great quad footage! this was really fun to watch :)

I'm feeling a coke bottle plane challenge coming on.. edf planes made from actual coke bottles

That jet is awesome! Building either a hovercraft or nutball for winter!

Thundercheif, thunderchicken, thud (as in the sound it makes when they hit the ground!), Full scale it did love low speeds at low altitude. Turn in point for the route into Hanoi was rumored to have so many downed thundercheif's on it that USAF flier nicknamed it thud ridge. Eventually, even the locals started calling it thud ridge, some older Vietnamese still use that name. The USAF Thunderbirds flew them (for one season) and the aircraft did not do well (too big, not terribly maneuverable, hard to maintain) so it was quickly replaced with the F-4 Phantom.

“Coke bottle” proper name is “area ruling”. Reduces drag on cylindrical objects. A prime example of the difference it makes in performance is the McDonnell Douglas F-102 which was unable to perform at the speed it was designed/claimed to have until it was redesigned as the F-106 with “area ruling”. A beautiful example is the B-58 Hustler bomber. Also the F-105 was second to the last of the Century series fighters (F-106 was last, some will claim F-107 or F-108 but neither went into production) even though the Thud was a tactical bomber it was also famous for pioneering the wild weasel mission in Vietnam. Famous book to read about the Thunderchief is “Thud Ridge by Jack Broughton”. It is about how poor leadership caused many tragic losses of personal and untold dollars.

Time to climb, low speed, and high speed competition between this and the F8 for the review. What a beautiful plane this is shot from the quad. Awesome video guys.

At 7:45 I suddenly had an amazing idea for a challenge! One of you guys gets to fly a plane, and another one is flying a quad. Both get the fpv view from the quad and have to fly the plane through a parkour in third person view. Maybe have two different teams flying at the same time. I think this would be awesome too see, but maybe a little bit too difficult ;)

That is some sweet air to air footage!

The THUNDERCHIEF was also called the THUD because it tended to crash a lot with new combat pilots. it's one of the few jets that had a bomb bay that was designed to carry a nuke, but in Vietnam it carried an extra fuel tank to extend it's range.

The Blackburn Buccaneer used the same aerodynamic design on its fuselage too. The fuselage of the Buccaneer was designed using the area rule technique, which had the effect of reducing aerodynamic drag while travelling at high subsonic and transonic speeds, and gave rise to the characteristic curvy 'Coke bottle' shape of the fuselage.

That capture of the shadow rising from behind the car... awesome shot!

Thoroughly impressed by those quad skills. You make it look easy, but I know I'd have wrecked that thing if I tried that.

The jet is cool, and TJ is the man on chasing...but one thing is missing: That dirt mound is screaming for someone to take an 8S Xmaxx up there and bash it up.

Plz put a 3rd person FPV tailcam on this!!! Awesomeness!

A running chuck and asks what degree angle you want it thrown at. Ha. You have three choices - 1. Directly up. 2. Directly down. 3. Somewhere (hopefully) in between.

I know Josh likes to fish and if I worked for you guys this time of year instead of a model RC car I would probably be bringing a fresh caught steelhead either from the Chagrin or Rocky River because I didn't have time to go home and clean it before my shift started. Anyway, the thunderchief was first called the Thunderbolt Two...named after WWII P-47 Thunderbolt. The original Thunderbolt was also nicknamed "JUG" and of course so was the Thunderbolt II....I don't know how the name got contoured to "Thunderchief"...Bob may know. Over and out ...YooperJon.

The F-105 Thunderchief is awesome, the coke bottle shape is an aerodynamic principle called the "area rule". When you review it, how about a timed pylon race with the F-8 and maybe some other EDF's?😀

Nice review!

Take it to a skeet shooting range and try to have the guys blow it out of the sky!! I want one!!

That's pretty awesome.. I've only flown quad but watching every episode of flite test since last February.. I definitely need a wing or plane.. I have to try one.. badly

Just for your info the "coke bottle" design is called area rule...its designed specifically to enhance supersonic performance. Also the F-8 crusader was the first fighter to be designed using "area rule"

It looks like a good candidate for the Fpv system. Looks smooth. I like it! Great review!

People like to talk crap about Traxxas. But I've enjoyed both of mine. Solid little vehicles.

Put FPV on that Thunderchief!!

Thanks, gents. In your review, I'd love to hear if either this F-105 or the F-8 would make a good first EDF plane, and if not, what model would.

the challenge should be a pylon race between TJ with the fastest to 270 he can build and the thunder chicken.

The "pinched" waist is called "area rule" it was discovered and is what allowed the " century series" fighters to get the performance needed!! The F105 is one of my favorite jets

For the review: Take it to the airstrip, bring the F-18 and do some high-speed agility challenges, laser-tag style dog fights, and top speed runs.

Dope show as always - buuuut it just occured to me, why haven't you guys designed a F86 Sabre foamie, surely that would be a simple build and would work well with prop and EDF , plus much simpler folds and design than the Viggen ?! - been some time since you guys released a new FT design - just a thought though...keep on keeping on ... also would be cool to see an episode where you guys show all the different types of DIY materials you could make your planes from ( granted they are mainly for foamies - but they also state DIY - so would be interesting and fun to see how the FT planes hold up with the various materials and how their perfermance compares to the foamie) ....stay shweet, stay fun.

105 was the fastest plane at low altitude the US ever had. One of worst turning,but fastest at low level.

The coke bottle design has to do with the Whitcomb wing area rule. They found the F102 couldn't go supersonic because the straight fuselage meeting the wing caused more drag than expected.

Ah, the Thud. Proof that, given enough power, anything can fly.

i love ur vids and they always help me understand stuff xx

Hey Flitetest, look up the Whitcomb area rule, that will explain why the fuselage has this coke bottle shape ;)

Shoulda put the Tokyo Drift music to the slomo car scenes :)

You guys should make a little action movie video using toys as the characters and for all the shots, like have some army men talking, they go on a mission, the plane crashes in the desert stranding them, they eat the dead guy, make a car out of logs, drive to salvation and its all good. I think it would be a great thing to do with those and some of those chase scene videos almost looked full scale...

Bomb drops! NAPALM BABY!
