Why the 3-channel trainer should be your first model
You want to get into R/C planes but have never flown a plane before, then choosing the right model is EVERYTHING. There are tons of Ready-to-Fly (RTF) or Bind-N-Fly (BNF) models but not all are geared for the beginner. The BEST entry-level airplane is a 3-Channel high wing trainer.
The main reason is that it’s the easiest to fly. Three channels are the minimum needed to fully control an R/C Plane. The three channels control the speed, height, and direction, here is how each one works:
Speed – This is determined by an Electronic Speed Control (ESC), it sends power to the motor based on the throttle input. The more power the faster the plane flies or the steeper it will climb. Some aerobatic models have motors large enough for the model to climb vertically. This is definitely overkill for a beginner but it having a properly sized motor is important.
Height – This is controlled by the elevator, it's the movable control surface at the back of the tail. To gain altitude pitch the nose up and to go down give the opposite input. A properly trimmed plane will be able to fly level when you take your hand off the stick. If you’re feeling daring full back elevator will pitch the nose all the way up and over to complete a loop.
Direction - This is controlled by the rudder. This works similar to the elevator but instead of changing the height, the rudder changes the direction. On a three-channel trainer, the rudder works with the wing to bank for a turn.
The elevator and rudder are controlled by small actuators called servos, they move in relation to the pilots' inputs on the control sticks.
One benefit of the high wing model is the inherent stability. The weight below the wing helps it naturally right itself if blown off course by the wind. It acts as a pendulum with gravity assist to return to its original state. The full-size equivalent is the Cessna 172, its far-and-away the most popular choice for new pilots looking to get into flight training. Full-size pilots like the Cessna for the same reasons R/C pilots like the high wing trainer. It flies great and is well-behaved.
One important factor not to be overlooked is the confidence boost a successful first flight will give. As with trying anything new there are always going to be risks, but minimizing risk is the goal.
The three-channel model is the best package to minimize failure. It has all the controls for true R/C flying, it only has the minimum needed parts and nothing extra, and it makes use of first principles for stability.
