I want to know the reason why my heli couldn't lift. Is it because of poor torque produced by the toy motor?
Another question:
Can stirling (Invented by Edward Sterling) engine be applied for household purposes? Can we make automobiles using these type of engines?

you guessed it right .it is difficult to get motors with high torque and low weight as well,as the first ans suggest take that hellicopter. if u want make hellicopter your selves try small 3.2-3.5 cc engines ,normally thy are used to make small toy hellicopters,aeroplanes.

A great way to have lots of fun for less money
This tiny super-lightweight RC helicopter is a blast of fun as soon as you open the box. You simply charge it from the mains (the more charges you give it, the better the flying ability - as the battery gets boosted up), and off you go. The counter-rotating double blades are the secret to making it easy to fly, as they stop the usual torque spin you get from a standard single rotor helicopter. To control the amount of torque, there's a trim slider, so you simply have to adjust this (much as you would a trim control on an RC car) to find the perfect balance.
It hovers with ease and is remarkably tough considering they've had to make it out of such lightweight materials.
This is by far the most awesome indoor flier toy and it makes a great inexpensive gift or something to mess around with while you are fixing your full R/C Raptor, Zoom or any other Heli. It's very lightweight, simple to operate and absurdly cheap. It comes completely assembled and ready to fly, has a range of up to 20m, and will fly for between 3-7 minutes per charge and when you're flying a helicopter around the room, that feels like a very long time.
