The TDC (Top Down Centre) Trolley is designed for the Maxx Hop-up chambers to incorporate the use of tensioner nubs specifically for Flat-hop builds (although some R-hop set-ups would work also).

Depending on the tensioner nub of various sizes and brands you choose to tend to use can help on the consistency, accuracy or achieve longer distances for your shots.

The TDC trolley will ensure an evenly distributed force applied onto the bucking down to the Flat-hop or R-hop patch. This in turn ensures the patch can maximize its appliance on the BB for the most stable and uniform spin for the much desired finely tuned performance.

The Maxx Trolley works in unison with the Flat-hop and Maple Leaf Super Macaron MR-Hops.

Features

Modifications on the slide bars on each side compared to the original. 

This ensures a tighter fit onto the chamber to achieve an absolute Top-down-center push of force onto the R-hop patch while preventing any tilting.

The overall contact area has been extended by 0.5mm compared to the original to cover most hop-up windows. This ensures all areas of the ER-hop patch are equally pushed down. In addition, this covers more of the chamber window for an increased air seal.

- Modified Maxx Trolley for most stable performance.
