The TVR-1180C Mk1 Stack Tri-Coupler is an adapter that allows for a single rocket to branch into 3 separate stacks.
Usage
All nodes on the TVR-1180C are designed for attaching parts with a diameter of 1 meter. As with all adapters, liquid fuel will flow through it. Despite the similar name, the TVR-1180C is not a decoupler; it does not jettison anything nor does it add a stage to the rocket. It branches into 3 separate stacks, but they are unsupported and prone to bending or breaking if the weight and thrust are not properly distributed. Rockets incorporating a tri-coupler are also likely to wobble, unless the stacks are opportunely bound together with EAS-4 Strut Connectors. The tricoupler is also subtly asymmetrical, so rockets must have control options to correct for induced pitch, yaw, and/or roll. The tricoupler has non-standard (0.3 instead of 0.2) drag, meaning it should be placed behind the center of mass.
Another, unconventional use of this part is as a landing 'foot' - when landing very large craft (such as bases), the stock landing legs aren't big or powerful - using the strut parts as 'legs' and the tricoupler as a 'foot', you can artificially make your own landing leg!

| “ | The Stack Tricoupler! If your stack is lacking in awesomeness, this is the tool for you! Just remember that this is not a decoupler, and won't separate stages. | ” |
Changes
- New model and texture
- Mass reduced from 0.8 to 0.3 (part rebalancing)
- (Undocumented part of fuel flow changes) added NoCrossFeedNodeKey = bottom (keeps fuel from flowing FROM the bottom nodes to prevent stack imbalances and such)
- Replaced tricoupler textures and UV mapping (UV map by Dippeggs)
- Fuel can now flow through Strut parts like the tricoupler
- (Bug fix) VAB placement bug with tricouplers and fuel tanks (and decouplers)
- Initial Release
