YouTube is strange sometimes.
Once I posted a link and all that came up was the main page.
Your link shows the same stuff that was up there when I opened the link
for novielo's actuator a days ago. Guess you gotta wait.......

oh... did you try those orange props on the stock AA motors?

Ha! After punching it up a few times I got it.
Never seen one scoot around like that- who needs wheels?
