Originally a 1:10 scale AXIAL SCX10 platform then fully upgraded with alloy parts and carbon chassis all over, i forgot the brand of the parts i used to replaced the stock SCX10 but definitely shows sharp solid quality build by the third party manufacturer...yes feels more heavy than stock too. Also i did a scale mods using hard body 4 door JEEP body added two G.I Joe figurine to keep up with more aesthetic looks. The scale looking classic steel wheels are from AUSTAR brand. My SCX10 JEEP runs on stock 540 size 55t brushed motor, Hobby Wing WP-1040 ESC, 2s 4500mah li-po battery pack, JX Digital MG servo and FLYSKY GT3B radio unit. Overall i love the trail and rock climbing performance of this model; not as close to comp crawler performance yet enough to keep it at 'scaler 4x4' level but definitely most heaviest 1:10 scale models in my collection and the only models that more aesthetic details both internal and externally. If i'm going out for R/C 4x4 scaler club activities this SCX-10 JEEP will always be my 1st choice to put on the show.
