Revell 1/144 KA-50 with working counterrotating rotors

[Wouter1981]

The kit is rather old (1998) but a decent one. No real fitment issues an a decent amount of details, but they are rather heavy. The riveting is way oversized, the canopy and rotor head is rather thick. Motorizing the rotors wasn't easy. Rather difficult to explain, but I made a gearbox with 3 small bevel gears.  The lowest gear drives a steel 0.5mm rod to the top rotor and that steel rod turns inside a brass tube of 1mm that connects the upper gear to he lower rotor. The last picture shows the mechanism I made. Hope you like it!

Outstanding way to show off a small helo! Or any helo, really!

Why?  Why do people have to make me feel so inadequate?  Amazingly well done, especially for such a small scale (my favourite scale, no less).

That is one low flying Blackshark. Looks good and well done with the prop mechanism.

Very impressive.

So much detail on such a small model. 

[Pete in Lincs]

Ingenious is the best word for this I think. Is a mechanical Bumble Bee next? A very impressive post in such a small scale.
