That was the point, a unicorn carrying impossibly heavy stuff. I wasn’t implying Twilight became an earthie from being discorded. Surely Dan must be tens of times heavier than the cake BM had to carry and he had a hard time with it as soon as it was loaded on his back, so it’s not a matter of tiring.

@Background Pony #EA90  
First, Twilight losing her horn doesn’t change her unicorn genetics, so it’s doubtful there was any change to her physical strength.  
Second, that cake was insanely heavy, and carrying it for a long time would wear anyone out, even Big Mac.

I fly a gigantic monster,  
I am captain, evil stopper,  
I get to wear big black helmets,  
I pilot the hatredcopter!
 
I fly the beast made of steel,  
Thick knives that cut the night,  
Gas tank is filled with vengeance,  
Machine guns shooting spite,  
Can’t find the thing that makes this,  
Thing take a hard turn right,  
I follow where it leads me,  
Blind bats with wings of might,
 
You, will most likely die,  
From the hands of my arm,  
When I come and fly and,  
Take off your face,  
With the front of my hatredcopter,
 
I fly a gigantic monster,  
I am captain, evil stopper,  
I get to wear big black helmets,  
I pilot the hatredcopter!
 
I fly the hatredcopter,  
I’m going to hunt you down,  
I get paid lots of money,  
For all the bounties found,  
Can’t seem to find the button,  
That turns the radar on,  
Can’t work the hatredcopter,  
The hunt for you is on,
 
I, am likely to find,  
From my failure to fly,  
That I will be fired for not killing you,  
Cause that is my job,  
Hatredcopter,  
You, will most likely die,  
From the hands of my arm,  
When I come and fly and,  
Take off your face,  
With the front of my hatredcopter,

Applejack has outclassed RD in raw strength in almost every episode besides Fall Weather Friends, whereas RD is always portrayed as much faster and lighter. True, we have seen some impressive feats of unicorn and pegasi strength. But on the other hand, we have Big Macintosh pulling a house, Applejack literally destroying the base of a large tree with one kick in the tonic episode (and lifting a bed over her head in another), Maud Pie being able to destroy rocks with her hooves, and many background earth ponies that are incredibly strong, like the train ponies in Over a Barrel. To be clear, I’m not saying that there aren’t weak earth ponies or strong Pegasi. I’m just saying that out of the feats of strength portrayed in the show, most of them are from Earth ponies, and the ones most consistently portrayed as strong are earth ponies, so you can’t really blame people for drawing the conclusion that earth ponies are stronger on average.
 
Of course, the writers use the rule of plot to some extent to determine who’s strong and who isn’t at any given moment, so draw your own conclusions. It’s just my headcanon.

@Nukechaser  
Outside our mains, we don’t see alot of unicorns doing anything.

@Nukechaser
 
Not that I’ve seen. Pegasus seem to be just as adapt like Bulk Biceps and the Wonderbolt’s in training. Rainbow Dash keeps up with Applejack just fine. Shining Armor threw Cadance. Don’t think I’ve ever heard it said Earth Ponies were stronger, sans Big Mac, I don’t think I’ve seen it either.

@Background Pony #EA90  
Not all earth ponies are that strong. But the episodes where earth ponies display incredible strength vastly outnumber the episodes that show unicorns doing it.

@Background Pony #EA90  
Rule of funny. Besides, earthpony!Twilight is bearing up quite well under that heavy rock.

@soundtea  
Maybe certain writers think of Earth ponies as being stronger, but others…
 

 

 
…not so much.

@Background Pony #EA90
 
She almost got a Princess that way. Curse you Rainbow.

@Vree  
Given that she’s an earth pony, and that Maud can smash rock into bits.
 
I say a lot.

@Background Pony #EA90  
She rams into them head-on.

She has victory tallies on the side but her copter isn’t armed.. does she just grind ponies with the propeller?

@Vree  
5 whole magic

@Vree  
1 horsepower.

Physics exercise: based on the size of the ‘copter and general aerodynamics, calculate the amount of force that a pony’s leg muscles can generate.
