Reinforcing the horizontal stabilizer Watching at the Horizontal stabilizer, I also thought it might be a good idea to reinforce it also with carbon fiber which should protect the tail from any eventual crash. This could be easily done with an old soldering iron and a peace of straight wood to use as a guide. I draw a line where i wanted the carbon rod to go and used the soldering iron to open a 3mm gap, just enough to fit my 3mm carbon rod. Also here I used CA glue to glue the carbon rod to the horizontal stabilizer. |
Reinforcing the main wing carbon tube
The default Bixler 2 carbon spar does not seam to resist very well the stresses caused to the plane during some basic maneuvers. There is a need to reinforce it so you can fly safely and even perform maneuvers with this great plane. To do so i inserted a 4 mm carbon rod into the main wing stock carbon tube of the Bixler 2 gluing them together with CA glue. after assembling the wing using the reinforced carbon tube, I could immediately tell the difference. It was obviously noticeably stronger and stiffer. |
Need to use a lot of FPV gear so the stock motor wouldn't handle all that stuff in there, so next mission - upgrading the motor. Items used:

2. Using two channels to control the flaps - this method is also easy, All you have to do is to connect two servos of the flaps in two different channels on the receiver and reverse one of the channels in your radio. Anyway this method uses two channels and I wouldn't recommend it unless you don't need all of the channels (who wouldn't need them now days :)).
|
1. Ordering a servo reverser, which is the easiest way. All you have to do is to connect the servo reverser to the servo in one side and to the Y harness to the other side and there you go, the flaps can be controlled from one channel. You can find servo reverser online or here.
|
3. This is my favorite option, because it doesn't cost anything, no need for extra space for reverser or for an extra valuable channel and you get yourself something to do :). If you think you can't do it, you better go with one of the above options. If you decide to open the servo and reverse it than here we go. There is one thing I need to mention. Not all servos are easy to reverse. There are chances to destroy the servo or the receiver if you don't work carefully. For example, don't try to reverse a Turnigy TGY 9025MG Metal Gear Servo 1.8kg/11g/0.09 cause you will most likely destroy it as I have destroyed one.

Bixler 2 flight and crashActually the mods we do are made to make the airplane easier, stronger and safer to fly. Yesterday, during a flight my Bixler 2 crashed. The reason for crashing was an aileron horn which got loose, disabling one of the ailerons which resulted in a going down spiral. The plane was undamaged except for the camera mount which was damaged but easy reparable. So here is the video of the flight and I'm also going to make a future tutorial on how to strengthen the control horns in order to avoid such crashes which may result in bigger damage to the plane or people.
