Aerocraft has used the basic undercarriage in the kit but have modified the engineering little to hopefully improve the installation of the undercarriage. As can be seen the assembly is the same as the kit, in that the base of the undercarriage is located onto the wing spare and the main part of the undercarriage strut is added towards the end of final kit assembly and or painting.
They have made a simple alignment system for Starboard and Port, as can be seen on the picture,
Note you will need to clean up some casting sprue gates from the parts and the odd small brass 'inclusions' that may appear through the casting process.
