do many 4D manoeuvres on a single transmitter. Meaning that you can fly your plane nose down and the pitch of the propeller can change to make it fly straight up. Here is what you will need to build a fully functional 4D aircraft. Be the first one to build it in your group, and wait for the oos and the ahs from your fellow R/C plane flyers.
What you will need:
-hobbyking hkt6a 6 channel receiver and transmitter
- Foam board or cardboard , card board is very cheap and extremely light
-pushrod, the type that can fit in your servo arm usually 1mm-1.5mm
-hingetape or plastic hinges
-Special 9"various pitch propeller with 1300KV motor set
-4 of the 9 gram micro servos
-hobbyking redbrick 30amp ESC
-Hobbyking HKT6A 6channel transmitter data cable
-3cell lipo battery
Step 1: The plans
-extra 330 from hanger 9
-extra 300 from hanger 9
-e-flite tribute 3d
-arrow v3 4d plane(already on the market)
These planes can be easily modified to fit the vpp motor&prop system.
Step 2: The wings and the fuselage
Next, i cut out and then hinge the control surfaces with light weight tape.
I used a hobby knife to cut out a slot for the vertical stabilizer and glued it in place with hot glue and CA. and then reinforced the bottom of the fuselage with bamboo skewers.
Then i cut out the slot for the wing, and permanently glued it in place with CA and hot glue. That was definitely a very strong bond.
Step 3: The electronics
The pushrods are made out of the steel wire. They are lighter than pushrods and have the same characteristics.
After that, i checked the movements with a receiver battery pack. They are proven very good.
The aileron servo was hard to install because the top of the servo was accidentally stuck to the fuselage, so i had to pull the servo out, clean it and glue it back in place.
Step 4: The power source
Then i connected the pitch control pushrod from the motor to a 9 gram servo. Which had worked perfectly.
I charged the battery and connected every thing together.
But the weather is so bad, it will be raining for a while and its freezing outside, it would do some damage to the prop, so i decided to postponed the flying date till the weather get better, and the wind is smaller.
I reprogrammed the transmitter for extra movement, now it really gives extra throw.
