Hello everyone !

Let me show you my last RC model : The SdKfz 251 22.

This 1:18 model has designed interior but contains also all the required electronics to make it move : You can control it with you phone via the Blynk app !

This model has been made as perfect as possible : Working tracks, animated suspensions and wheels, moving cannon and machine gun, openable hood, doors, boxes...

It is more than 1500 parts to keep you entertained for hours.

You will find step-by-step instructions on this Instructable page, from hull to program.
