F3C for DummiesAbout 30+ years ago I taught myself how to fly a Carl Goldberg Gentle Lady glider. I would hand launch it, fly it, do it again and again and again. Eventually I moved on, joined a club called the FORKS and got into powered airplanes. A couple “old guys” (I was 14) helped me out and after a few lessons and a few crashes, I was comfortably flying powered models.
Engine Oil Know-HowEvery mainstream gas helicopter currently on the market uses a two-stroke engine that requires oil to be mixed with the fuel (usually by you). Glow fuel, on the other hand, already has the oil mixed in and the percentage of oil is much higher. Oil content in glow fuels is typically referenced in percentages based on the total volume of fuel (gallon or liters). Oil content for gas helicopters is typically referenced as ratios like 32:1, 40:1, etc. You can calculate the actual amount of oil by dividing the ratio into the total amount of fuel (gallons or liters) and the result will be the amount of oil in ounces or milliliters to add in order to achieve the target ratio.
Advanced Radio Programming
As we progress in this hobby, entering the compulsory model settings into our transmitter often becomes second nature. And the more we use any given feature (or collection of features), the more we’ll tend to almost subconsciously dial in just the right settings to achieve our desired control behavior. If we look at each programming feature singularly, it’s relatively easy to appreciate what it offers and how we can put it to good use. However, when features are combined they often interact with one in other in ways that can make your head spin trying to wrap it around exactly what’s going on.
