Building a micro heli guidelines

by Hogster

Attach the servos with hot-melt glue rather than CA.
Attach the CF undercarriage struts with hot-melt glue rather than CA.
Put the servo pushrods in the hole second closest to the servo.
Remember not only not to glue the boom into the chassis, but also don't glue it into the tail motor assembly.
Use training gear - 2x50cm 2mm CF rods with ping-pong balls pushed on the end, rubber-banded to your helis skids - gives a much larger 'footprint' and prevents the majority of tip-overs.
Glue the main motor pinion on with CA to stop it slipping - a slipping pinion causes no end of confusion for newbie pilots!
Buy some CA debonder!
Do all radio tests with the main rotors and tail rotors OFF!!!
Check all ball-links are free enough to fall under their own weight. If they're still gently squeeze your balls .... AHEM I mean the balls the links are connected to!
Check the main motor and tail motor gear mesh. Either set the gear mesh using the paper method described in the instructions or just make sure that about half of each gear tooth is in contact with the other gear tooth. You can also 'hear' and 'feel' if the gear mesh is bad.
Use metal main rotor blade bolts - 2.5mm are good metal replacement ones for the plastic bolts that come with the kit.
Check the flybar paddles have NO negative pitch to them.
Tape some foam over the front of the Piccoboard - the PiccoB is usually the thing that hits the ground first in a crash!
Always check the centre of gravity of the heli before flying - do this by holding the heli by the flybar (close to the rotorhead) with the rotor blades parallel to the tail boom. The MAIN SHAFT should be perfectly vertical. If not, shift the battery pack around until it is.
Get rid of the battery connectors that come with the kit and replace them with either 2mm gold bullet connectors (easiest to get hold of in the UK) or some polarized Micro Deans connectors (get 'em from the US).
Solder the main motor wires to the main motor - get rid of the tacky plug and socket that comes between 'em - saves weight and reduces resistance.
Check that when the servo arms are horizontal that the swashplate is horizontal. If it isn't either bend the 'kink' in the middle of the servo pushrod or reposition your servos.
If you find you can't get the servo arms perfectly horizontal with the trims at centre point on the Tx, try (if you haven't cut off the other 3 arms) removing the arm from the servo and rotating through 180 degree and re-installing it.
Replace the white nylon bushes with ball-races on the main shaft, the tail rotor shaft, and on the rotorhead.
