Whiffs found on Facebook

Mr.Creak,
I think you'll find that Madoc & I were referring to the image in Reply #142 by Flyer, not Reply #146 by the same author.

Oops.
Colour me embarrassed! 

All good!

Mistakes happen - if they didn't I wouldn't be here!

Found on facebook just now, not a Whiff but I thought it was unusual, it has given me a few idea's too.

Caption for pic:

Today's aviation curiosity is the rather ungainly Burnelli UB-20 "Lifting Fuselage", the 1st U.S. aircraft to use flat metal stressed-skin construction. The pic below is from a 1934 Sun Oil Company promotion to prove their petrol, or "gas" worked at sub-zero temperatures. An extremely brave Mechanic actually descended into the Ford V8 to fire her up at altitude! Three UB20s were built.

Interesting as the caption states a 1934 promotion while the car is a '35 model.

Didn't they introduce the following year's models in the September of the previous year?

It was definitely done like that in the 60s when I worked in the motor industry and when I asked why it was always explained that 'That's the way the Americans do it'.

These days the annual model change either doesn't happen or the manufacturers time their releases to fit with the major motor shows around the world.

Yes, you're right Kit, and they still do

Now that thing is neat !

Good find....Burnelli eh ?

[Dizzyfugu]

I think we already had this one - it's a nice idea, though, even though the "semi-spats" look a bit weird?
I considered a Japanese Ju 87 on floats for some time...

Even though it's carrying a torpedo, the floats are totally in the wrong position ---

[PR19_Kit]

Yes, with the engine out there in front of the main body of the float it'd make like a submarine even with the engine off!

When adding floats to aircraft they are not intended for my general rule of thumb is to put the step under the wings centre of lift.

I put floats on a 40ish inch wingspan R/C Extra 300 a few years ago, I started out with the step about 3/4 inch behind the centre of gravity, so roughly on the centre of lift but if there was not any chop on the water it would not come unstuck, I progressively moved the floats forward until the step was about in the same place as were the wheels were originally and didn't have a problem with it sticking but directional control became really touchy. May have just been a trait of a aerobatic aircraft with a fully symmetrical airfoil, but it has been the only R/C floatplane I have tried so I have no comparison. I still have the set of floats so I'll be doing another in the future. But I agree, on a static model the step on the centre of lift looks right.

The step should be close to the 'load' cg, for a tail-dragger the step should be behind the wheel center by a couple of feet, for a tri-gear it should be in front by a couple of feet. (that's scale feet BTW)

It sure looks the part! I would have to have a series of running horses down the side.....

if it is a Titan Mustang then it would be powered by a small block Chev

The Titan website suggests a Honda 3.5L V6 engine as the most powerful engine.

The Thunder Mustang (also 75% size) with a 640 HP Falconer V-12 (or maybe a 1000 HP turbine) would be nice...

Ok, I didn't know that, I didn't research it either I have only seen the one I mentioned earlier and that one was Chev powered, thought they would all be the same...

...I read a article about the Thunder Mustang a long time ago and if I remember correctly although it is stressed to much higher levels than the human body can withstand the controls are very heavy and it's power off glide ratio is in the house brick category.

I have a habbit of trying Google always when I get curious  I wouldn't be surprised if somebody has put a V8 in a Titan P-51. Builders of experimental aircraft have been known to, er, experiment 

The Thunder Mustang apparently performs better in some ways than a real P-51. Maybe its glide isn't much better

Ok, so I didn't technically find this on Facebook, that is where they found it so there.

That is very nice work! I just wonder what this person used to glue all those different types of plastic together. That's one thing that keeps me from using plastic bottles and such.
