Assembly and Modifications

So, the fun part began ...

First of the fabrication of motor mount for stronger outrunner brushless motor, to compensate for the intended extra weight.

Next the carving of the airframe to create the extra room for the motor mount, stronger wires and the payload area.

Following by the modification of the wings with the aileron mod, which consisted of mesuring, cutting out the aileron plates and carving out the servo space.

After all the cutting and carving came the gluing phase. Pretty straight forward, airframe, elevator, rudder, payload door. Some deprom foam was added at the cut out edges of the payload door for a tighter fit, since cutting them out weakened the airframe. Also, the rudded was extended to give it more authority to cope with the increased weight and stronger motor.

On the wings, the aileron plates were attached with enforced paper strips, connected with a steal wire to the servo motor and the connecting control wire glued inside the wing withing the hole for the reinforcement tube.

After it all set, came the carving of a tight fitting space for the G1 and the motor regulator. Once it all fit together, were the payload doors equipped with a strap made from duct tape and secured with Velcro.

Obligatory electronics test and color coding of the wires. Interesting fact: 250W old computer power supply did not produce enough current to start the motor, so the test was servo mechanism only and as a result motor connections were color miscoded.

After weiring it all together and performing another test with a charged battery, the polarity of the motor was corrected and with the 803g without payload and 1047g with was ready to fly.

No markings or tail number as of yet due to a writers block in the naming department.
