Flybarless miniTitan
=============
components:
helicopter: Thunder Tiger Mini Titan v1 e325
motor: Turnigy 2836 Brushless 450-Size Heli Motor 3700kv <link>
ESC: Turnigy Super Brain 40A Brushless ESC <link>
gyro: Tarot ZYX <link>
servo - tail: Futaba 9257
servo - cyclics: Spektrum H3020
blades: Edge LE-325 = 315mm (hole to tip), 32mm chord, weight 23.6g
blade spacer: PV0829
blades: Tail - KBDD 60mm yellow
metal upper mixing lever: pv0805
pinion: 11t
head: stock flybar head rearranged to flybarless configuration. blade tip to tip 730mm

doublelink = 18mm hole to hole
long link = 44mm hole to hole
links below swashplate
from left servo to swash 36mm
from right servo to swash 36mm
from elevator servo to swash 20mm

links above swashplate
swash to mixing arm 41mm
mixing arm to blade grip 18mm
gap between head block and mixing base 4mm

   
Re-arrange the flybar head to a flybarless configuration

1. Remove the two 3x3mm set screws that hold the flybar in the flybar cage. Drill two holes in the mixing base and install the set screws. You can see the set screw in the picture on the above.
2. In the picture above you see the long side of the mixing arms have been cut off.


3. In the picture above you see I removed the pins from the bottom of the head block. I twisted them with some pliers as I pull outward.


4. Install the bell-hiller mixing levers in the holes that the see-saw hub was attached to.
5. set the doublelink = 18mm hole to hole
6. set the long link = 44mm hole to hole







3gx installation which I no longer fly

I have a lot I want to add about this heli. I have flown it a lot!!! over the past couple of years. I just need the time to start adding the tips, radio setup, and mods.

Tip Anytime you have a crash make sure you check the radio bearings in the blade grips. I checked the spindle and it was not bent so I assumed everything was good up there. Well four sponteneous crashes later I finally figured out that one radial bearing was notchy.

Tip: After any crash make sure you check the top main shaft bearing. This can cause vibration that will interfere with your tail gyro or flybarless unit.

Tip: The plastic head block is weak in the area that the flybar passes through. In a crash this often breaks and damages many other parts in the process. A metal head block is a good solution to cut down on damage. However the Thunder Tiger head block is relatively expensive. What I have been using is the one from cnchelicopter.com. It is only $10 USD.
