Tail Belt Pulley Note:
Before tensioning Tail Belt, check
if correctly positioned in
both Belt Pulleys.
- Be sure the boom is assembled and installed correctly.
- Loosen the tail boom by loosening the eight M2x6 Hex Cap Screws.
- Adjust the Belt tension by pulling on the Tail Boom.
- Tighten the eight M2x6 Hex Cap Screws.
- The belt must have good tension. We suggest re-checking after a few
flights. We suggest to check belt tension often, before each flying session.
- If spool up get difficult, may Tail Belt is over tight,
recheck and eventually loose Belt tension little bit
- If the belt is often loose, you should check the lock system or belt integrity.
- Tests show that a hard 3D pilot can perform over 400 flights before the belt
will fail. We recommend replacing the Tail Belt after 300 flights, even if it
does not show wear, to avoid it breaking unexpectedly in flight.
- After a crash, spend some time checking Belt integrity and replace if any
teeth are missing.
don't over tighten

Use a Screw Driver to check
Belt Tension (suggested max
deflection is 1mm)
- Note: We recommend a tight
Belt tension.
- If spool up get difficult, may Tail Belt
is over tight, recheck and eventually
loose Belt tension little bit
- Check the Belt tension again
after the first 2 flights.
- With a new Tail Belt, when the
head is rotated slowly, it is normal
to hear a tooth sound as the belt
engages with the Main Pulley. This
sound is normal and will disappear
after a few flights and the necessary
"break-in".
