Ten years ago, or thereabouts, I tried to build a micro helicopter after being inspired by a New Scientist article. After numerous attempts, I failed : (
Ten years later and you can now buy 15cm long RC helicopters for $17.50 online. Ah, the march of technology.
I've bought a few of these now and they're heaps of fun to fly. The latest in my collection is the Mosquito micro helicopter. I haven't flown it yet but I thought I had to share something from the manual that is written in that appalling Chinglish.
Googling 'hypogastric joggle' merely gives references to this manual so I still haven't a clue what a 'hypogastric joggle' is.
Anyway, I guess I'll figure it out after flying the heli a few times : )
