USMC F/A-24A Helldiver II

Silly question maybe but what kind of tape is that for your masking?

Silly question maybe but what kind of tape is that for your masking?

It's long thin sausages of Blu-Tac (don't know what this is called where you live - it's like semi sticky crap you can use to put posters up without putting holes in the wall) to give the feathered edges. The tape in the middle is B&Q (British equivalent of Home Depot I guess. I live in Belgium but buy all my masking supplies on trips home.) own brand low tack masking tape. This tape very thin and easy to cut without disturbing the Blu-Tac sausages. Some of the edges are secured with 10mm Tamiya tape.

Awesome!

Absolutely bloody brilliant

I have to tell ya, I first scanned the pics and went, hey cool, a 27 in US livery. How nice, and I simply didn't clue in untill the shot of the back. The fecken thing looks so slick and right I simply thought it was an OOB build. What skill! It really looks right!
Great job mate!

[Captain Canada]

Wicked !

Didn't notice the four engines at first...pretty darn cool ! Love the way it looks from the top...that'd be one powerful beast !

And in order to save money, just buy the 400 dollar hammers instead of the 700 dollar ones.  

[wolfik]

first now I was seeing the two engines....hmhmm....  
good good....

[B777LR]

what speed? if the two engines of a SU27 can make it go mach +2, then this must be able to do mach +4

[PolluxDeltaSeven]

Hum... The top speed is not a question of number of engine, it's more complicated...

For example, the twin engined Rafale is a Mach 1,8 plane, while the single engined Mirage 2000 was a Mach 2+ fighter!!
And it's not a question of maximal thrust too: Rafale has 15-18t thrust while the Mirage 2000 was only 9-10t !!

Another example, the A380 with 4 engine isn't twice faster than the B777...

It all depends of the plane's design, its weight, drag etc etc...

[Ollie]

Whoa!

I just noticed this!

Awesome!

     

[gunfighter]

Sure it can get supercruise, that´s a matter of thrust to weight ratio or am I wrong?

[Dork the kit slayer]

Whats to say??.........just brilliant.      

[Ollie]

Supercruise is more a matter of aerodynamic cleaness.

The F-22 is not the first plane to supercruise, Concorde could do it, it used to cruise supersonically without the burners (only used for acceleration).

[gunfighter]

I think the MIG-31 Foxhound ( the real one) was supercruise capable, and so does the Typhoon.

[AeroplaneDriver]

Problem is that drag increases exponentially with speed, for example 2 x speed=4 x drag.  As drag increases, more thrust is required and so on...

[PolluxDeltaSeven]

That's right!

About the supercrusing planes, we have the Concorde, the Mirage IV, the Mirage 4000 (even able to supercruse few minutes with only one engine!), the Typhoon, the Rafale, the F-15, the Su-27 and maybe the Super Hornet?
All the example I said could supercruse with some external loads (most of time a couple or two of air-air missiles, sometimes external supersonic tanks)...

So, the F-22 wasn't the first one to do that... The amazing fact with the Raptor is that it could supercruise with a FULL load of weapons!! And it could do that for HOURS !!
