Sorry, I thought I pasted it.  

For real, it looks like he realizes he can't make the climbout and/or got rotor droop (doesn't happen as fast in a UH-1) and used right pedal to give him a little more holding power, then he realizes he can climb by doing that and tries to keep the rotation but then seems to struggle to control it at that point.

I would assume this is a high altitude location given the spanish nature so power would certainly be limited.
