KWA TK45 Series - TDC Bracket Converter Kit (R-HOP/FLAT-HOP/ MR Maple Leaf)
The TDC (Top Down Centre) Trolley Converter is designed for the KWA TK45C 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.
The longer patch would achieve an improvement in accuracy and consistency from shot to shot, typically for sniper DMR builds.
The idea spawned originally from the TDC trolleys found on Maxx Hop-up chambers to achieve a perfect top-down force against the hop-up nubs. We designed this converter to be fitted onto the current chamber to function in the same way and with minimum difficulty.
Recommended Hop-up type
- R-HOP (Elvish, Psionic, Silent Sniper)
- FLAT-HOP
- Maple Leaf MR Hop buckings/ Super Macaron/ Super Silicone

Perfect Top-Down-Center Hop
Once installed you can obtain the fully functional TDC hop alongside the advantages of keeping the original hop-up unit designed for the gun which can prevent situations like misfeeding or double feeding.
The TDC Bracket
The main bracket: This fits onto the original KWA hop-up chamber and acts as a medium to guide the trolley moving vertically up and down to apply hop-up. It is designed to restrict the movement of any other axial directions, and limit only on the vertical axis.
The Vertical Trolley
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
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.
Modified Hop-up Arm
Lastly the modified arm is used to apply the desired force onto the trolley and then the R-HOP patch.
Gain the Competitive Edge
This kit does not require any modifications to any part of the hop-up chamber or part of the KWA airsoft replica and an elongated pin is also provided to lock down all of the parts, however, a dab of glue is highly recommended on designed points of the chamber/ TDC kit to ensure there are no unwanted movements later on.

Ultra-Tough Polycarbonate
The TDC Kit is manufactured through plastic injection molding using polycarbonate as the material which is lightweight and tough against the stresses while installed into the hop-up chamber.
Tech Work For Successful Install
Once you have tested the hop up works on your set up. Use the Zip tie (supplied with the kit), to lock the TDC kit into place. Do not over tighten – a firm amount is only required. Leave for 12 minimum and/or 24 hours to fully cure (dry). This is ensure there are no shot to shot inconsistencies so is highly recommended to do this step.
