The TDC (Top Down Center) carriage is designed for Maxx Hop-up cameras to incorporate the use of tensioning nubs specifically for Flat-hop configurations (although some R-hop configurations would work as well). The TDC carriage will ensure an evenly applied distributed force over the nub of the nub towards the Flat-hop or R-hop head. This, in turn, ensures that the head can maximize its application on the ball to obtain the most stable and uniform spin for the much desired tuned performance. Works with Flat-hop and Maple Leaf Super Macaron MR-Hops. Features: · Modifications on the sliders on each side compared to the original: This ensures a tighter fit on the chamber to achieve absolute top-down force thrust in the center of the R-hop head while avoiding any tilt · The overall contact area has been enlarged 0.5mm compared to the original to cover most windows: this ensures that all areas of the patch are pushed down equally. Plus, this covers more of the chamber window for a greater air seal Modified carriage for more stable performance Increase accuracy and consistency of shot Rugged polycarbonate construction Compatibility: MAXX CNC ME - PRO aluminum vault chamber & SPORT · Aluminum jump chamber MAXX CNC MI - PRO & SPORT · Aluminum jump chamber MAXX CNC SV - VFC SCAR-L / H · Aluminum jump chamber MAXX CNC ME - Umbrella Armory Ver.
