Intimidator model airplane plan


Flying Models's Intimidator

A few nerve-wracking lessons are a part of every designer's life and the R/C Intimidator handed Marty some to remember. it's a well-tested, capable stunting machine. Intimidator, by Marty Meyer.
When I first started working on this design back in 1969, I had but one thought in mind. I wanted it to look sleek, yet built from a minimum number of parts. I wanted to get away from that usual boxy square look that you find in so many of today's multi airplanes. I was striving for a durable, light and fully acrobatic airplane that would perform the entire AMA pattern. I wasn't looking for a fancy job covered with dozens of fillets, fairings, and cowlings which add absolutely no functional purpose to the aircraft, except exotic looks and excessive weight.
It took me about four weeks to draw up the plans and complete the entire plane. I first tested the design at The Rockland County R/C club's field. There were at least six modelers present at the time and I must admit I had a little jelly in my knees at that moment, for there was no backing down. The weather was perfect and the engine was howling. I had no legitimate excuse for aborting the test, so down the runway she went. The takeoff was almost perfect and to my surprise, it required very little trim. It flew right off the board you might say. Roll rate was just perfect and they looked as if they were machined to order.
The design flew much faster than I had anticipated with the thick wing, but the flight did point out one fault which I corrected easily. During the construction I thought it would be cleaner if I could conceal all the pushrod linkages within the fuselage itself. The elevator gave me no problem whatsoever, but I goofed on the rudder. I had connected a piece of .075 dia music wire to the articulating hinge area, which was connected to the rudder. The wire proceeded to extend down through the top of the fuselage and onto this extended wire I had silver soldered a control horn.
The entire system looked beautiful except for one thing, it didn't work. With a rudder as large as this, I should have known better. I had no leverage at all with this .075 dia wire exactly on the hinge point. As the plane was flying at the higher speeds, it picked up such a tremendous rudder flutter that I had visions of the entire tail section being torn off.
After my second flight, I was convinced that I had enough for the day and went home to make the necessary changes. I mounted a rudder control horn directly to the rudder in the conventional manner, but I mounted it about 3/4 in to the rear of the hinge point. I mounted a link (outside the fuselage) to this horn and this gave me all the leverage I needed. I flew the ship again, and the problem I had encountered was now solved.
This ship performs exceptionally well in all kinds of wind conditions, without the slightest tendancy of empennage yawing. The plane will stay in the position you place it in. You must fly it all the way, but you have the sensation that you are really the pilot in the plane itself.
After building three of these ships I was being hounded by dozens of modelers who saw it in flight and wanted a set of plans. There are over thirty six in the making at the present time, fifteen are in the Blue Angels Club alone and several have hundreds of flights on them. They all vary in weight of course, but seem to fly the same. Some weigh in at six pounds and other builders go up to 7-1/2 pounds. It is all up to the finish the builder chooses.
I don't claim this to be the ultimate model of all time and I doubt any modeler has the right to say that. As time marches on, so does the R/C equipment, the pattern becomes tougher, and the design of the plane must also advance. No one can say what the model plane will look like two years from now. It may even have the tendency to look wingless like some of our fighter jets of today. It wasn't too many years ago that a high wing cabin type airplane won the Nationals and every modeler yearned for that plane. Today, we would consider that design just a heap of lumber, and we wouldn't even consider it for a trainer.

This airplane has the ability to fly at quite a high rate of speed, yet when you throttle her down, it can be flown to almost a standstill. I am often asked just how slow it can fly before it stalls out? I honestly can't say, because of all the Intimidators flying in this area, no one has ever seen one stall. I would like to mention at this time that I didn't copy this airfoil from any known one when I drew up the plans. I just picked up a french curve and drew out what I wanted. I'm sure that if I did any research, I would probably find a duplicate somewhere along the lin

Member Profile for André


I'm André Costa (Brazil), I build and fly model airplanes since
1968 (F/F, UC). At 1974 I ingressed in RC, my first radio, was a Logictrol 3 ch, the engine was OSmax 25 rc and Falcon 56.
In the 80's I build varied scale model airplanes. In 1985 I started the construction of a experimental ultra-light airplane in wood, which flew sucessfull in 1991. Currently, I dedicate to the research of inventive solutions for light electric models.
With my son Geraldo, I’m editing plan’s for you!

What are you ordering:

You are ordering a print from the main PDF file in this listing, it´s exactly like taking this file in a thumb drive to a local print shop and ask them to make a print.

About the plan source:

You should verify if the source file has the quality for the type of construction you intend to do, we will print the file without any kind of enhancement or scaling. To know if the file is good please download it and open it on a pdf viewer like Adobe pdf viewer and set the view level or zoom level to 100% or 1:1 or full scale or actual size, depending on which version or pdf viewer you are using. Also, using the measuring tool make sure all the parts fit together and have the correct size.
In doubt please ask us for an opinion.

Plans Scaling:

We can scale this plan for you. But please keep in mind that if this plan is not vector, if you enlarge it too much the quality will be degraded.

You will receive:

  • Laser Printed plan on good quality Bond paper or/and Tracing Paper and/or Polyester sheet of the PDF file from this listing, depending on what you have purchased.
  • Rolled sheets, up to 5 in the same cardboard tube.
  • Envelope, up to 5 sheets per envelope.
  • Articles and Instructions if they are available and if you order them.

3D Printed Parts
Order 3D Printed Parts for the Intimidator

General Information

3D printing allow us to design not only complete airplane models but also parts to complete balsa, foam or even composite model airplanes.

Parts can be designed and printed to fit exactly a model you have or a model you plan to build, even if you are not building this model to the full size plan.

3D Printing, and 3D CAD allow us to create the actual parts to fit on our models but also allow us to create negative molds where we can make composite parts.

I´m adding this service to all the plan listings on the site knowing that not every part you imagine or need can be done, knowing this, jobs will be evaluated case by case and a price estimate will be given on request.

What can be done with 3D Printing:

  • Canopies
  • Cowls
  • Wheel Pants
  • Landing Gears
  • Wing Ribs
  • Motor Mounts
  • Servo Trays
  • Servo Covers
  • Wings
  • Fuselages
  • Complete Models

Full Models, Wings or Fuselages

It is possible to design a complete model for you but keep in mind that this is a lengthy process, many hours are needed to design and test a fully 3D Printed model. The finished model cannot have the same internal structure of the wooden made counterpart because it wouldn´t be possible to print it, it would have to have a structure like the models you can see in the 3D Printed Kits section of the site.

From the outside they are very loyal to the plan but still they have to be printed in sections, typically to fit a 250X210X200 mm cube that is the printer maximum build volume.

3D Printed planes are also heavier than light balsa models, all built up and ready to fly, with an electric power system they are generally a little lighter than the same model if it were powered by a glow engine. Please have a look at the 3D Printed kits section to have an idea on this.


I will calculate a price upon request, please contact me here mentioning this PlanID: 97999 and the job you wish me to do.
