Specifications
You should check the play in the tail blade after installing the tail blades. There should be
approximately 12 mm (half inch) of play in the tail blades. If you have significantly less or
more play, then you should remove the tail blade and readjust this screw.
• Pg 13: The M2x6 screw (67561) should not be screwed too tightly into the short ballend
(67564) on the tail. If the screws are too tight,then the tail pitch lever will not move smoothly
around the middle of its range because the ballends will not be free to flex outwards. To ad-
just this screw properly, screw it in completely, then reverse it approximately one-eighth
turn. This should be about right but you should check the pitch lever movement to verify it
moves smoothly.
• Pg 13: The pitch lever (67541) must move VERY freely on the tail housing (67548). On an
unmodified ECO this is very sticky, which will make the tail "wag" with a heading hold gyro!
To fix the stickiness problem, rub the post where the pitch lever mounts with some extra
fine steel wool to remove the grooves left from the molding process. Next, apply some
powdered graphite to the post and to the inside of the pitch lever and mount the pitch lever.
Wiggle the pitch lever a few dozen times to spread the graphite. The pitch lever should now
move very smoothly.
• Pp 16-21: Don't use servo grommets to mount the servos to the frame. Instead, cut a 4mm
length of very small fuel tubing and slide this onto the M2 screw. When this tubing is com-
pressed, it will fatten out and fill the gap between the servo and screw.
• Pp 16-21: If you are using the aluminum swashplate with 120 CCPM, mount one servo in
front and two in the back at the 12 o'clock, 4 o'clock, and 8 o'clock positions. This is easier
to mount than two servos in front and one in back. You will need to fiddle with the transmit-
ter swashplate setting to swap the front and back with this servo configuration (SWASH
AFR on the Futaba 9C).
Note: This servo arrangement will not work with a frame brace (because the front servo will
hit the frame brace) nor will it work with a stock Hacker B50 heatsink (because the heatsink
will hit the frame brace). The Hacker B50 heatsink will require about a 1.25" section of it re-
moved so it doesn't interfere with the front servo.
• Pg 22: The suggested component placement will work if your gyro requires mounting on a
vertical surface but does not work well if using a gyro which requires mounting on a hori-
zontal surface such as a Futaba GY240 or GY401. If using these gyros, then mount the
gyro on top of the tail boom support behind the shaft (instead of the receiver) and mount
the receiver upside down under the tail boom support (where the frame is angled). This
component placement keeps the ESC far away from the receiver and gyro and prevents ra-
dio glitching problems.
10.8. Specific tips for Logo 10 only
• See www.logoheli.com for excellent construction tips
• Some Logo 10 kits are missing parts and/or including the wrong sized ball links. If your kit
has this problem, you should contact the retailer who sold you the kit and explain your
problem.
• Many Logo 10 owners have reported the tail belt builds up static electricity in the tail boom.
This can cause glitching and/or ESC failure. Extreme care must be taken with component
placement.
• The Logo 10 stock plastic swashplate has been known to separate in flight. This leads to
loss of control and probably a crash. You may want to immediately upgrade to the alumin-
