is higher. Later on if you want more lift you can switch one of the blade grips to a 6 dot
blade grip.
• If you are at a high elevation, you may not get enough lift using two 4 dot blade grips,
however. In this case, you should use the manual-recommended grips.
• The labels on the main rotor blades seem to be attached using the world's stickiest adhes-
ive. The residue from the adhesive can be easily removed using WD-40 or Goo Gone.
Warning
DO NOT USE ACETONE. ACETONE WILL MAKE THE BLADES BRITTLE.
THE BLADES MAY SHATTER WHEN THEY HIT AN OBJECT.
• The Fusion 35 controller on the LMH Corona is a relabeled Castle Creations Pegasus 35.
• The Fusion 35/Pegasus 35 seems to have trouble arming on many transmitters. If you turn
on the transmitter, then turn on the Corona and do not hear two beeps, then you are having
this problem. To fix this problem, you need to set a lower endpoint for the throttle channel
on your transmitter. For a Futaba 9C, go to Menu->End Point->THR and set it to 125/125.
• Many people make "tail boom protector" for the Corona to protect the tail boom from boom
strikes. This is usually foam wrapped around the tail boom or a strip of 1/4 thick balsa or
3/8 dowel tie wrapped to the tail to prevent the rotor blades from denting/bending the tail
boom. Other people use a "rotor deflector" which is a piece of wood or angle aluminum
mounted on the tail to deflect the rotor blade.
• The feathering plate should be parallel to the swashplate. If these are not parallel, then you
may need to loosen the main shaft and slide the main shaft down a little bit until the two are
properly parallel.
• The newer Corona tail gearboxes appear to be much more fragile than the older ones. One
option is to use an aftermarket tail gearbox such as the Ballistic Technology or Chopper-1
gearbox.
10.3. Specific tips for all Piccolo (Fun/ECO/CP upgrade/Pro)
• The stock plastic motor pinion may slip on the motor shaft. We recommend using CA to
glue the motor pinion onto the motor shaft to prevent this from occuring.
• Drill a hole through the landing skid (67361) so the struts (67378) will go all the way
through the skid. This will make the landing skid much stronger. If you don't do this, then
the nipple on the landing skid will probably break off in a hard landing.
• When building the landing skids (67361), use thick CA instead of the thin CA included in
the kit. The thin CA runs all over the place and is difficult to get in the right place. Also, CA
the rear skid struts into the frame FIRST. Then CA the front skids into the frame and make
sure they almost align with the rear skid struts. If you don't do this the landing skids will
probably be crooked.
• Do not use CA to glue in the tail boom. This usually works too well. When you crash, it will
be almost impossible to remove all the tail boom bits and you will have to drill out the re-
maining pieces. It is much better to put a few layers of CA on the ends of the tail boom and
let this dry thoroughly, then friction-fit the tailboom into the body and the tail rotor assembly.
• The landing skids may pop off the frame in even mild landings. You can reinforce the land-
ing gear by CAing a length of CF rod across the front and rear landing gear skids about a
