Here are some of the changes we made to the stock Edge540T
First we made our own motor mount to handle the larger sized motor.
We used a DAT-750 motor with an 11X8 GWS propeller but the motor is most efficient with 11X4.7 GWS propellers. (DAT-750 statistics)
We added our own landing gear with a slightly larger gauge steel, greater ground clearance and a wider stance.
The plane was originally wired with a 72 MHz Tx/Rx (transmitter and receiver) and later fitted with a 2.4 Mhz Tx/Rx.
Standard 9G servos worked great.
We added a stronger tail wheel for better control on the ground and greater durability.
We used both stock wheels and then we decided to switch them out with a more durable and slightly larger diameter wheel.
We also added a small piece of Velcro and a windable key chain light to the nose. It is a nice look but in also helps with orientation in the late afternoon hours.
