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 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.
