Introduction
This page aims to answer some of the common "Which is better?" questions seen on the forums in a simple manner.
Normally, there is no simple resolution to the question, because if there were, you wouldn't need to ask it. For example, if we knew pneumatics were best, then you wouldn't see any combustions.
It's not as simple and clear cut as people asking the question might think. However, this page will hopefully give you the information you need to make the decision for yourself, depending on what is most important to you in your launcher.
Combustion vs. Pneumatic
"Which is better? Combustion or Pneumatic?"
This is probably the most common question that gets asked on the forums, and the big problem with it is that it is unanswerable. Without knowing what a person wants from a spudgun, nobody can put one type ahead of another.
However, most experienced spudgunners will agree on this short list:
Where down is ascending order of "power" but also difficulty to use and build.
But, here are the main advantages and disadvantages in easy lists for you to decide on your own:
Combustion cannons
Advantages:
- Usually cheaper and easier to build
- Usually quicker to refuel and reload.
- More portable. Just needs a can of some flammable vapour, not a pump or compressor.
- Can be made bigger, but still kept practical.
- Easier to later upgrade.
Disadvantages:
- Less power, with a upper limit to what is practically possible.
- Less controlled (Power is very hard to change)
- Often inconsistent and unreliable.
- Potentially noisier
Pneumatic cannons
Advantages:
- Normally more powerful, with less of a "ceiling" to power.
- More controllable, as power can be varied with pressure.
Disadvantages:
- Takes longer to load, unless you have a decent compressore
- Less portable.
- More complicated to construct.
- Leaks are a greater problem.
As a final note, a large majority of the launchers that Spudfiles (and other similar spudgun forum) users build are pneumatic cannons, but amongst people who don't take it up as a hobby, combustion is more common.
