Phasing block: when the one of the link balls on the swash plate inner ring is on the same line of the ball
on the A arm, the main blade holder should be parallel to the boom. This is standard setup, for advanced
pilots, you can changethe angle to get a better rolling. Fix the radius block when the two pins can stay in
the gap of radius when both highest and lowest pitch.

Adjust by actual flight.
Setup of Linkage
Install fuel tube, install gyro, main blade, muffler. check the servos and gyro, reverse them if necessary.
at 0 pitch (for 3D pitch stick in the middle) adjust as following:
1. Adjust the horn and sub trim so that the horns are 90 degree to links.
2. Adjust the link between the horn and front arm (and L arm)so that the L arm and Front arm are horizontal.
3. Adjust the link between L arm and swash plate so that the swash plate is horizontal.
4. Adjust the link between the washout control arm and flybar control arm so that the washeout control arms are horizontal.
5. Adjust the link between mixing arm and swash plate inner ring so that the mix arm is 3~5 degree lower than the fly bar.
6. Adjust the link between the Mixing arm and blade holder to get0 pitch of the main blade.
7. When gyro is in 0 point, adjust the horn and sub trim so that the horn on rudder servo is 90 degree to the tail rudder link.
8. Adjust the length of tail rudder link so that the tail blades have 7 degree positive pitch (wind force towards the tail).

Check:
Tail Balance:
Heli Tail rotating at very high speed, regular check the balance of the tail is important
for safe flights.
Antenna:
It is strongly suggest not place the Antenna around boom supporter, boom or other
metal parts. uggest place the Antenna underneath the plastic skid foot.
Wrongly installation of Antenna would result a larger chance of interference.
