Airtech Studios TDC converter kit for Prowin M4 hop-up chamber

The TDC (Top Down Centre) Trolley Converter is designed for the PROWIN Hop-up Series to function perfectly for R-Hop and Flat-hop setups using a trolley system that applies hop perfectly downwards for the most consistent pressure distributed onto the BB. As a result, more accuracy over longer distances.

Features:

• Increase hop-up surface
• Steady BB flight
• Increase accuracy
• Improve shot consistency

There are 4 parts that come with the converter package.

• The main bracket: This fits inside the chamber and acts as a guide to move the trolley up and down. It is designed to restrict the movement of any other axial directions apart from the apart vertical axis.
• The trolley is fitted inside of the bracket and can only move up and down the vertical axis controlled by the bracket while using the walls of the original chamber to prevent the trolley from swaying left and right.
• The M-nub ensures an evenly distributed force is applied onto the bucking down to the RHOP 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 R-hop performance. This is stuck onto the trolley via a strong 3M sticker.
• Lastly the modified arm is used to apply the desired force onto the trolley and then the R-HOP patch.

Includes:

• TDC Bracket
• TDC Trolley Unit
• M-Nub
