- What are the reasons to have a big, 1 piece, canopy, instead of following the recommended path
?
- I did not want to use the mechanism given, for holding the canopy as it takes space inside the fuselage, and does not work after sometime.
- It is much easier to be able to have always access, to the entire inside of the fuselage, in case you want to replace anything and especially because in my setup, I decided to put the Receiver/ESC BEC as far as possible, in the back of the fuselage
- How to lock the canopy, then ?
- I use a standard rubber band, going outside. It does not look as good on the ground, but does the work in the air and is not noticeable as well while flying.
- In case of crash, if they are in front of the battery, chances are that the battery could destroy them in the shock
- Gives then the full space, to decide where you want to put the battery, as to balance the CG, with these 2 motors, the battery needs to be more in the front
Some other will tell you to have them as far as possible from the motor (interferences...).
This setup works fine for me, and is easy to use.
- I use Velkro tape inside, which you see in black on the pictures. IT is all over as this way, it would take most of any type/size of battery and hold them tight during the flight. For most batteries, since they are wide, they should be Velkro taped inside the fuselage with an 30 degree angle, meaning they touch let's say the bottom right and the upper side left of the canopy.
- Because of the heat, it is possible that the velkro would want to leave, if you pull the battery immediately after the flight. It does not do this anymore for me, but when it did, I just waited a minute before removing the battery
- Kontronik recommends to have the Servo wires, as far as possible from the motor. I used the standard holes for them and it works fine for me.
- As for wiring the cable. you have to think how to save weight so:
- Get the 3 cables out of each motor, and solder the pairs (red with red, blue with blue, green with green), as soon as possible inside the back fuselage, in the hole that will be covered by the piece of wood later on.
- Then you should only have 3 cables only going inside the fuselage. don't forget to mark who is who, but if you do forget, it is anyway no big deal.
- As for connecting to the ESC, plug one. Then play with the 2 others until you see that both motors turn inverted.
- You could also follow the colors and just plug one
color correctly and 2 others switched
- I use the CAM 5.5 x 4.3 which does overall very good work.
- Follow the link for table on it
- Jurgen heilig recommends that if I would replace these props with 6x3, it would go vertical, but at the price of lower speed.
With the 5.5 x 4.3 props, you get verticals, not unlimited, but far long enough to get the plane out of sight, which is more than enough and it is fast, so it is acknowledged as a good compromise, altogether.
Hope it helps, good luck ! With this setup, the TwinJet is just a completely different fish. Even at 30% Throttle, it climbs...
Take off are a piece of cake, and it is altogether much easier and safer to fly, as you have the power, if needed, to get out of sudden unwanted situations.
