3 Unique Mechs

Spoiler: Video Solution

Very fun tricky level... I was a bit stuck until I "saw"...

the way to bring L to the spot between the first mech to do the long autopilot

once that, all went smoothly... thanks for sharing @Meko Guy
Ahhh, btw, I did the first step differently... I KNOW that you will like it ... a mixture of the two tricks with the right timing, easy to perform

I had problems with unreliable herc push at 2:50 causing restarts but as @Nuyoah has not mentioned any then i will stick to 5*. I had a different start that worked well so that i was surprised to see the designed start that was clever.
Edit.. i see that i had the same start as @delator77 .

@delator77 - Great start and easier to execute (if the mech) moves upward. It did that here too but not all the time so I needed to use a reliable method so added the tap. Thanks for P, C and R.

@ridgerunner - That herc push only gave me issues when the fuzzy tap happened. On my device, the tap would go on L's pillar which will not push far enough so had to ensure that I tapped more to the other side of the block past L. Thanks for P, C and R.
