Gents, what TL hasn't disclosed, is how Lurker Industries have been able to miniaturise an OS52 4-stroke, and all the 2.4GHz radio control gubbins, into components the size of a pin head so they are hidden inside the balsa parts.
Not only that, he then flies the thing using thought control. No, I dunno how it's done either. I used to think very hard "pull up, pull up!!!" when flying my, admittedly, rather larger aircraft, but I never had the success at thought control flying that TL clearly does.
Very clever people, those guys at LI.
