Republic P-47D Thunderbolt (oz14395)

About this Plan

Republic P-47D Thunderbolt. Radio control scale model WWII American fighter. For 6 - 10 cc motors. Wingspan 1380 mm.

Quote (google-translated from the German): "The construction of the model is kept very simple and the flight performance is satisfactory in every way. When I design a model that is true to the original, I want to replicate it with exact dimensions. I strictly reject any concessions.

The original machine was built around the new engine; the model around the size of the air screw. With a 10cc engine you can use a staff of 0 300mm, so I decided to use a 1:9 scale. This results in a model with a wingspan of 1380 mm. The flying weight of the model is 2.6 kp, which still gives a favorable wing loading. The transportability can also be described as good for small cars.

If you have some building experience, you shouldn't have any problems with the replica.

The wide undercarriage equipped with 0-100mm wheels will not bring any problems. If the runway is reasonably level, the model will take off after just 7 m when the elevator is pulled. Climbing performance is very good when using a 10cc engine. The flight characteristics can be compared to those of a multi-channel trainer. Due to the large fuselage cross-section, the speed difference between level and climb flight is very small with a light construction.

The model can be controlled with the rudder alone. However, if it is flown with ailerons, it develops amazing manoeuvrability. Landing presents no difficulties; the landing speed is low, thanks to the wide undercarriage equipped with large wheels there is no risk of the model overturning, even on uneven ground. The tail wheel is coupled to the rudder so that the model can be steered very well on the ground. On hard slopes, however, a wheel brake must be installed. Even with the engine fully throttled, the model starts rolling very quickly, the skid starts to jump and the wheel no longer has any traction even when the elevator is fully pulled. That's the end of the steering. It is best to couple the wheel brakes on the front wheels in such a way that the brakes are effective when the engine is throttled and the elevator is fully pulled.

When starting, the elevator can then be fully pulled, since the lever position of the motor throttle steering machine is different, and the brake cables therefore remain slack. To start the engine more easily, an opening is created in the hood at the carburettor socket through which fuel can be injected into the engine.

Starting the engine is a bit unusual because of the thick bonnet, but after a few tries you won't find it annoying anymore. This bonnet does have one advantage though, it's already half a sound absorber..."
