The Stearmans are built from Balsa USA kits but have had some modifications to make them lighter and more detailed.
To get the best performance we need to keep the weight as low as we can, whilst not compromising the strength of the structure.
The tailplane was made removable to make the planes easier to transport. Both planes are transported in one van so they take up less space with the tailplanes off. Carbon fibre tubes are used to join the tailplane. Elevator servos are in each half of tailplane
The Breitling team use Super Stearmans which have more flying wires than the Stearman so extra mounting points were fitted to attach the additional flying wires. Hard mounting points also had to be added to attach the wingwalker's rig.
The spar size in the wing was reduced by half and webbing used to make the wing as light and strong as possible. The square aluminium tubes in the kit were replaced with round ones and are not glued in. That way they are easy to remove so make transportation easier.
The nose has been shortened so the prop hub is in the correct line. A completely new cowl was made and starts from the cabane struts. On the full size the cowling was a modified Beech. New wheel spats were made to the correct shape and a new spinner was made. The spinner on the Super Stearman is a Harvard.
