Guys.
FBL head on the Chaos 700 was based on the origional version which still used the normal main shaft. The new version uses a shorter main shaft and there are some mods that need to be done. If the metal control arm links in your kit measure 71mm you will need to do the following.
• Move balls from outer holes and put them in the inner holes. This measures 24mm center hole to center hole. place a dab of lock tight on the backs of the screws where the nut attaches.
• Blade grip link shafts are 71mm long. 2.5mm needs to be shaved off of each side to make the blade grip link shaft 65mm. This will allow you to screw down the ball linkages down so that they are 83.5 (plus or minus) center hole to center hole. *on the next batch re-spec to 65mm*
• Origional bell crank links going to the swash plate have about 32mm of metal showing. These need to be cranked down to about 26mm of metal showing. This will give you approximatly 59mm centerhole to center hole.
• At this point place swash leveling tool on and adjust the belcrank linkages so that they are perfectly level.
• *Note for BeastX users* After the above step go through the beastX programming and set the swash centerpoints and trim if needed using the beastx programming following the Beastx manual.
• Replace 2 of the balls 180 degrees opposite one another with ones that do not have a spacer. (the origional balls on the swash are 2 long for the FBL geometry.) These are the balls that the control links attach to. On the BeastX you should be able to teach it 6-6.5 deg geometry according to the manual and have a blue light *Red will work but try to get the mechanical setup tweeked so that it will be blue.*
• Install head and linkages. The phasing collar should have a 2 mm gap between it and the bottom of the head. This makes the arms on the collar level at midstick.
• Power up electronics and 0 pitch the blades by adjusting the linkages.
• Program 3axis gyro according to the manual from this point.
Note on first test hover you may have to adjust the cyclic gain a bit for your individual Helicopter. Patients here is the key and will pay off as once the Chaos 700 is tuned it will be a very agile and responsive machine.
Hope this helps
