I'm planning to build the model as a Thunder Tiger Pro 40 powered racer, also called Q-40 Sport or 425 class racing.

The kit builds into a model that looks like a real aircraft. It will fly around 130 mph and can be built for about the same cost as a 424 class racer.

The following pages will show the construction of this model and promote the Q-40 Sport class of racing.

Below is a photo of the plans.
