About this Plan

Nervous Nellie. Control line stunt model.

Quote: " If you think you are pretty good and want a ship that will leave the spectators weak and shaking, then Nervous Nellie is for you. Nellie doesn't look nervous. She looks like a gentle old goat with a strong blend of free flighter, but fire up the Mac diesel in her nose, turn her loose and you'll find yourself inventing stunts you'd never think possible.

Verticaleights from take-off; triangular loops; somersaulting end over end in her own prop-wash, all come easily to Nellie.

What's her secret? It's relatively simple. It's a gimmick known as a 'flying tail'. Consider the average elevator, hinged approximately in the middle; by bending it up or down we deflect the airstream and so move the nose of the model in a new direction. This works quite well, but bending a flat plate in the middle results in a sharply angular section which is highly productive of drag. Thus loss of flying speed occurs in every maneuver due to elevator drag. In addition to that, speed is lost due to changing direction against inertial forces.

Nervous Nellie has a different type of elevator. This one is pivoted to rotate - it simply climbs or dives in the propeller wash according to the amount of deflection imposed. Control surface drag is reduced to a minimum and as a result the model whisks through maneuvers like a greased eel.

Tighten up on any stunt and the model simply rotates around its center of lift. Loops of eight foot diameter are not only possible but practical - you have complete control right down to walking speed; just keep the lines tight and you can literally tumble the model end for end without losing control..."

Hi Steve, Here is a picture of this plane. It was flown at the US vintage stunt comp in 2013. I don’t know the builder (yet).

I am the builder. Mark Gerber. I built my first Nervous Nellie when I was in high school and built another one for old times sake. It wasn't flown in the VSC competition -- just for fun.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
