Just in case you were, I decided to make another one and take pictures along the way.
It's made from a mini rc car chassis and a rc toy helicopter.
If you were to buy everything used in this project, it would cost about $25-$40 depending on where you buy the parts.
My inspiration for this project started as an experiment to see how much faster a helicopter control circuit was than a mini rc control circuit. The results were astonishing.
This instructable features version 2, there isn't a lot of differences between version 1 and 2, but I considered several faults with version 1 when making version 2.
Step 1: Materials and stuff
-Toy mini RC car
-Toy mini helicopter
-Hot glue and hot glue gun
