Technic Quest Kodiak
This model is my first attempt at building a Technic aircraft, and attempts to expand the functionality of Technic plane models.
About this creation
Aesthetics:
This being my first plane, it is hard for me to judge its looks. It is quite boxy, but so is this plane, as planes go. The red parts make it look good, as well, I think. I made it a stylish sign, as well, to put at the base of the stand, and to hide the IR receivers. Most notably, though, it is really big!


































Opening Stuff:
The front doors open, as does the rear side cargo door. See them open! See them close!









Interior: I tried to do a bit of an interior, with two seats and a control panel. There is a crate inside the cargo compartment, but don't look too close, as it subtly hides an M-motor!











Propeller: The propeller is driven by a couple M-motors geared up three times before the small turntable. More notably, though, a Servo motor tucked behind them pushes an axle through this turntable, to add variable pitch control, which is controlled along with the drive motors. They are linked on the controller, but they are still on different channels, so the propeller's pole reverser can be flipped to allow for a reversible propeller (like the real Kodiak) without messing with the Servo. Also, because of some petty foolishness (Involving one of my receivers breaking down, V2 receivers not working with M-motors, my V2 receiver's red channel only working with Servo motors, and my insistence on having the propeller and pitch motors on seperate channels) I had to use a servo motor controlling the speed dial on the battery box to run the propeller motors. It really shouldn't have to be that way, but said petty foolishness required it of me.













Ailerons/Tilting:
The plane has functioning RC ailerons using an M-motor (positioned on the base, and mechanically linked to them through the stand), but, in a first taste of the real highlights of this model, it is coupled with an L-motor that drives a rack via a worm gear to actually tilt the plane--as it should when the ailerons are activated!

















Elevator/Tilting:
Like the ailerons, an M-motor also tilts the aileron (using some vintage flex system stuff), and another L+worm+rack tilts the plane forwards and backwards. Incidentally, I had to thread three independent axles through the stand--while allowing for the tilting in two ways, and rotation! In the end, I pretty much ignored the rotation, as the torsion of the long axles, unreinforced between their ends, caused little problem. I stuck three U-joints through the axes of tilting, but they would still slide up and down, so I had to add extending axles, made of springless shock absorbers, inside the stand. Despite all this fuss, it ended up working quite well.















Rudder/Slewing:
Another L-motor on the base turns the rudder, but rather than using two motors for this function, the same motor works the rudder and turns a 56T turntable through a worm gear to rotate the entire plane on its stand, with some dramatic twisting of support beams! It worked fine, though.



















Flaps:
A M-motor inside the plane works the flaps (which can't move very far. This is a result of my foolishness in not determining certainly which way they should tilt before I built it. My flaps used to move up, and were changed at the last minute to go down. They can't go far, though, without hitting some U-joints for the ailerons.) There is no dynamic motion of the plane for this function, because I was unsure what it would be. Flaps are just supposed to increase lift of a plane, usually for takeoff and landing, but I wasn't sure how to express this. I suppose I could have moved the plane up and down vertically, but this would still be unrealistic, and VERY CHALLENGING. Anyways, the flaps just worked on their own, and were quite simple.




Controller:
I tried to make the controller fairly faithful to the controls of a real plane. Thus, the ailerons are controlled with "foot pedals," the throttle and flaps with levers, the rudder by turning a wheel, and the elevator by pushing or pulling said wheel.























Overall, it was quite an interesting model to make, being my first plane and quite innovative and interesting. In addition, it was HUGE dimensionally, and very dramatic to operate. This model was a lot more interesting to my family and friends than some big 'ol supercar with highly complicated but pretty much invisible functions (Gearbox, brakes, etc.)
