Many RC modelers today start out with small, electric-powered ARFs, and work up from there. As they get more involved in the hobby, the next logical step up the power scale is operating nitro-burning glow engines (2-stroke or 4-stroke), and learning how to keep internal combustion engines happy. When RC’ers make the major step into giant scale, the operation of gasoline-burning big-block engines comes into focus. Whether the aircraft is a big 3D aerobatic plane or a giant-scale warbird, the gas engine is, by default, the usual choice. Gas engine are fairly easy to operate, but you can’t treat them like garden equipment. When you operate big gas engines, there’s a lot of RC setup you need to keep in mind if you want the best possible performance out of that big hunk of metal bolted to your firewall. What’s the big deal you may ask? Let’s see what’s involved.
