About this Plan

Dart Cart III. Radio control profile sport model, for .35 power.

Quote: "Designed by Bill Warner, this Easy-To-Build profile stunt and sport design is truly phenomenal. Capable of all maneuvers, its slow speed and landing characteristics are fantastic.

Are you flying more, but enjoying it less? Try this little model and see if your outlook doesn't improve, Airline Captain Bill Warner expressly designed this model to fly from small confined areas. Its easy handling characteristics at slow speeds is fantastic, yet it is gentle and forgiving enough for the beginner. It is also capable of all maneuvers that the pilot is proficient in accomplishing. All of the flight testing on the Dart Cart was done at the local schoolyard where room is at a premium, but for the Dart Cart there was room to spare!

This airplane is especially great for the beginner because of its slow speed approaches. Due to its light weight there is a mimimum of damage from hard landings. Its power-to-weight ratio will keep you out of trouble as long as the model is built and kept light.

l recommend a good .35 engine for your Dart Cart. We used an OS .35 with a Perry carburetor and found that to be ample power. If you use a .40 you are almost assured of VTOs! This model could also be used as a test bed for some of you Formula I flyers that want to break-in that hot engine you're going to use in racing,

The model is simple to construct, but here are a few tips that might be helpful. Make sure that all surfaces are covered with silk or silkspan prior to assembly. This adds strength where strength is needed. The wing structure is strong enough for some of the new iron-on coverings if you desire, but I suggest silk (sorry, Sid) on the fuselage and fin area.

Mount all servos on aileron type mounts to soak up the engine vibration. The battery & receiver of course, are always packed in foam for protection,. Always protect your radio equipment as best as possible to minimize the possibility of damage due to crashes. When using a .35 engine, vibration shouldn't be any problem on fuel, but we noticed that when a hot .40 was used the fuel had a tendency to foam when the tank was partially depleted. Be especially careful in mounting the fuel tank loosely and it won't give you any trouble.

We used a 10x6 Top Flite prop for the .40 pound version and a 10x5 or a 10x4 for the .35 prototypes. Another nice feature is that the engine and fuel system is right out front where you can see it and work on it as necessary. Your fuel supply is always visible for fueling and you can detect any leaks that might occur. The ease of cleaning and the removal of the tanks when you're done flying is simple. The tank can be removed so you don't soil the car upholstery with fuel!

The ground handling is phenomenal. Even when the wind is blowing hard, and the big ones are having difficulty returning to the pit area, the Dart Cart can return in any direction and taxi back with ease, much like steering a car. Spins, like 70 to 80, are accomplished with ease. On one occasion we turned 101 spins without really trying. Limbo is a piece of cake, either inverted or upright.

The battery should be located forward of the CG when using a .35 and to the rear of the CG when using a .40, You'll have to play with this since engine weight and installation of equipment will vary with each builder. For the throttle and nose steering, we used flex cable and NyRod tubing..."

Notes

* 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.

Scaling

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.
