When I am putting together a larger model airplane, I find it easier to put the servos as close to the control surface as possible. The larger planes tend to have more space in both the wings and the fuselage. Placing servos this way can result in higher precision and takes little (if any) routing of your control rods or control lines through the fuselage itself. If you’re looking for the challenge of putting together a larger plane kit and haven’t yet caught wind of our 12 Foot Telemaster Balsa Kit (due for release late this September), you should check it out. There is no lack of room for your servos or pretty much anything else you want to add in this huge frame.
Whenever I am putting together a smaller park flyer type model airplane, I have noticed that the lack of extra room in some of the internal areas of the aircraft can create the need to mount my servos in the main cavity or even on the outside of the fuselage itself. Assembling my planes this way forces me to use longer control rods and fashion some way of carefully routing them in the model’s covering. To give these mini models the most accurate balance, I have found it helpful to place them as close to the center of gravity (CG) as I can.
These little planes may not have all the internal room their bigger cousins do, but they make GREAT planes to take with you wherever you go! Also, if you were to get one of the smaller park flyer aircraft, you would find they are excellent as trainer planes! This class of model plane tends to have the distinct ability to fly both indoors and outdoors. They are a great way for beginning pilots to earn their wings.
