Speed Champions

 I'm Having trouble building speed Champions.

I built the speed Champions newer sets and most people love them but I had trouble putting them together.  To reduce tightness And pushing together, the pieces on the other side of the car fall off as they arent locked at times. 

The pieces that are small are hard to determine the chirality of.  I feel like I'm trying to determine molecular structure with a model set while using then in a game of tetris.  The pieces that are 1/4 size of a dot piece are hard to apply esp to small sections that are built.  The small fender pieces fall off.  I can't get the Lamborghini front to stay on and the Ferrari was very difficult.  The pieces are hard to pick up like a coin on a table.  The 007 car canopy won't stay on. (76911 set)

I don't claim to be the best or the fastest builder but I wouldn't call the cars relaxing to build.  I think I'm old school where plates stack, headlight bricks were the thing, cars were studded ie police station.

Here's places I think it's hard to see instructions in the 007 car

 

Another problem I have is clipping subunits to bars...pieces fall off...i.e. ferrari (set 76914)

Also in the set 76914 above

I cannot get the black clips to attach to the gold oval 1x2 pieces and stay on in set 76915

Above 2 pics show black clips attach to the gold bars vertically 76915

 And pieces i.e. the small silver pin pieces fall off as below...see step 3 below

The same problem occurred putting the 007 car together (not shown) 76911

Another place where pieces keep falling off during the build is as below in set 76914

Those pieces are hard to keep on and small to hold.  Additional small subunits pieces are noted in set 76914

Hard to hold while assembling above as it falls apart if pieces are not tight together.

I think the lighting, fat fingers, too much force pushing, small pieces are just hard to do...obviously I'm not one of the quick builders.  I don't blame lego, it's just me.  Any tips or similar experiences would be appreciated in the comments section.
