CL Navy Carrier Applications
This section is meant as a guide for the possible applications for the Navy Carrier, Class I and II events, which are best suited for electronic control, in order to contain servos within the airplane structure.
For many years the Carrier pilot has had to contend
with dropping the hook at either low throttle, or by a snap
movement in the down or up elevator line, or by linking it to the throttle linkage, and
set to drop at 1/2 speed. The GS Products, JR, Brodak 3 line handle offers trigger
control for the throttle, but everything else must function inside the plane by mechanical
linkages "piggybacked" to flight controls or with complicated timmers.
Sometimes, very hard to do in a Corsair or other plane that does not have
straight wings, and still be within the maximum gross weight, contest limitations.
Now, with the ScaleMaster, "WingMan", you can raise your gear right when you come off the deck for an additional 3 to 5 mph on your "high speed" run. For low speed you can drop the gear, add in flaps and drop the hook all with individual control while you inch in throttle to maintain constant speed. Flaps are proportional and with practice you can find just the right amount of parasite drag to get a very solid low end. Remember your low speed begins when you signal for the low speed run. Taking a few laps to "dial" in your speed should be no problem, with a little practice.
The fact that you have 1 less control line to drag around the circle makes a big difference and "micro" servos, to handle the functions, are not that heavy. Of course, building the airplane light is still the key in good performance and stable flying. There are many areas of the aircraft that can be lightened up enough to compensate for the servos and batteries.
By "Y" connecting Throttle, Rudder and Aileron together, in the plane, by use of 1 micro servo, you can add in proportional control to keep your plane tight on the line and wings level to the deck.
Micro servos work well for Throttle control as this is a no pressure operation. Flaps should be 2micro servos, one in each wing for each set of flaps. The hook also can be a micro servo, but should be set up so that the pivot takes the load off of the tail hook and the servo only controls the up and down movement. Air works well for the Gears with a Micro Servo for actuator of the valve. All will work from a 4 cell battery pack giving 4.8v. The key is to build light, but strong so that these additions do not take you over the 4 pound gross weight limit.
There are other handles out there that offer 1 to 4 functions, that are well suited for the 2 or 3 that are needed for Carrier, however, the ScaleMaster has many options that they do not. Check them out and see for yourself.
No matter what handle you use, or event you fly, Safety is the first rule....Fly Safe and fly well informed. Pick the product that is best suited for your need and study it. Read all of the instructions and take the time to learn. When all is said and done a good pilot is a well informed pilot, and there is no substitute for practice. The hobby/sport of model aviation is rewarding in many ways and can be a source of enjoyment through your whole life.
