As stated by others, the instructions are very incomplete and you will need to rely on your past model building skills to complete! Also as stated you MUST reinforce landing gear box...my first landing (one bounce) completely pulled off the landing gear.
This is more of a pattern plane, big rudder and elevator, but ailerons are too small for good snap rolls, it will roll OK, but it's lazy.
Using a 800 kV motor, 80amp esc, 4500 4s battery and 13-6 prop, 5.1 lbs., that combo has plenty of power.
