IT IS YOUR RESPONSIBILITY TO READ AND UNDERSTAND THE INSTRUCTIONS BEFO- RE YOU BUILD AND FLY THE HELI BABY NT. Always keep the following rules in mind: - During motor tests on the workbench, remove main and tailrotor blades and take care that nothing can get caught in the rotating parts of the model.
- Page 4 Start with the assembly of the upper frame. Join the frames H1 and H2, the bearing blocks H3 (2x) and H4 with hex screws M3x35 D338, countersunk screws M3x35 D324 and lock nuts M3 008 to- gether. It is not necessary to sand chamfers on the edges of the frames as they are alrea- dy smooth and it may result in scratches on the surface of the carbon.

- Page 8 Fit the main gear assembly and check the clearance of the unit. The mainshaft must protrude a small distance from the bottom of the unit. If the clearance is too large then add washers 10x16x0.1 046 or 0.2 033. If the clearance is too small then add washers 5x10x0.1 044.
- Page 9 Overview of the motor mount and drive unit components. The brass spacer bush H12 is pushed onto the motor shaft. Then fi t the pinion gear S974. The grub screw hole in the pinion is positi- oned so that it lines up with the fl at spot on the motor shaft.
- Page 10 1. Fit the second grub screw M4x4 573 with Loctite and screw into the second hole of the pinion and tighten (1.7Nm). Put two washers 3x6x1 051 onto the hex screws M3x8 D197 and fi t through the motor carrier H10. Finally add Loctite to the screws.
- Page 11 Screw the assembly to the motor carrier holder H11. The motor unit is pushed from below into the upper frame. The holes in the frame should align with the holes of the motor carrier without being forced. Otherwise adjust the height of the pinion or add washers.
- Page 12 Check the gear mesh by moving the main gear wheel slightly in both directions. A small amount of play should be noticable. If the gear mesh is too tight, loosen the hex screws holding the mainshaft bearing blocks and press the blocks to the front. If the gear play is too much loosen the hex screws of the motor carrier and the bea- ring blocks and press both together.

Overview of the rear canopy plate mount and the tail servo mount components. Prepare the tail servo holder mounting block H25.
- Page 19 First mount the block using only the upper two holes in the frame. This is so it can be tilted later to tighten the screws more easily for the tailservo holder. Mount the upper rear plate connector H24 with two hex screws M3x8 D197 and Loc- tite, but leave loose.
- Page 20 Add the tailservo holder H27. You may have to fi le the corners of the slot in the rear plate, but only a small amount. The holder should fi t in the plate snugly. As soon as the holder fi ts into the slot (note it is slightly angled) as shown in the picture it should be secured with two hex screws M3x10 D328 on the mounting block H25.

- Page 26 For easy mounting of the tailrotor servo use small pliers to hold the M2 lock nuts and after nut is in place use a 4mm open end spanner to tighten. Now mount the two roll servos. Tighten the hex screws on all servos making sure the rubber blocks are compressed slightly so that the servo is held securely and does not move during operation.
- Page 27 Overview of the swashplate linkage com- ponents. Screw two balls M3x9 078 and a guidance ball bolt D530 with Loctite into the outer ring of the swashplate D528. Assemble the elevator rod 106mm H33 with two ball links 2.5 041. The length bet- ween the links is 88mm.
- Page 28 Attach the swash plate leveller D529 with the small recess to the top. Place the swashplate on the leveller. This height is now the zero degree position used for adjusting the correct length of all rods. Screw the H32 ball links to the two roll ser- vo rods 92mm 2.5 041.
- Page 29 The swash plate holder H34 is provisi- onally fi tted with two hex screws M3x35 D338 and lock nuts M3. When mounting the tailboom the swash plate holder will be removed to make fi t- ting the toothed belt easier. Overview of components of the rotorhub and feathering spindle.
- Page 31 Overview of components for the blade grip assembly. Push the blade grips onto the mounting ring and align the four holes. If the blade grips are tight, warm them up with a hair dryer. Fit 4 hex lens screws M3x6 D199 and shim washer 3x6x0,2 455 and mount them loosely with Loctite.
- Page 32 Overview of rotorhead components before assembly. For mounting of the head, it is recommen- ded to add a drop of oil into the shaft hole of the hub. Carefully push the head onto the shaft straight down, never turn the hub on the shaft (risk of seizing).
- Page 33 Overview of the tailboom components. Slide the two tailboom clamps H39 on to the tailboom H38 on the end without the holes in the boom. This is easier if you open the slots in the clamps a little during fi tting with a small fl at screwdriver. Push the toothed belt H40 through the tail- boom or pull it with a long hooked wire.
- Page 34 Push the tailrotor housing onto the tail- boom and pull the belt as shown through the housing. Next insert the pulley wheel D579 into the belt and push it into the housing. Check that the spacer is on the correct side (where the pulley fl ange is smaller).
- Page 35 Tighten the lower two screws on the boom clamps and then tighten the belt by pulling the tailboom out. The belt should be tightened so that it has no slack but not so tight that it will twang like a guitar. Adjust the tail output shaft to be right ang- les to the main shaft.
- Page 36 Overview of the tailrotor linkage. Push the small head screw 092 into the slider ball housing and add an aluminium washer D79. Attach this unit using Loctite to the tail bellcrank H41. Fix the tail pulley on the tailshaft using two grub screws M3x5 0737 and Loctite.

- Page 42 The tail control rod H49 is supported through two small mounts H46 and one large mount H45 at the front. Slide the wire through the three mounts. The dis- tance of the front mount to the frame is 6-8mm. Use the supplied insulation tape to fi...
- Page 43 Screw the bellcrank with Loctite onto the holder. Make sure that the slider ball is lo- cated in the ball housing before tightening. Check that the tail control rod is right ang- les to the tail bell crank and the servo arm, if not adjust the link at the servo until this is achieved.
- Page 44 Place two pieces of foam on the controller platform for ESC and telemetry sensor. Tip: If later you use a P-Clip D348 for hol- ding the battery cable remove the left front screw from the controller platform. Place cable-ties D112 as shown. The ties must be pushed through the slots in the platform.
- Page 45 View of the wiring slot in the rear frame and the sockets of the Microbeast. Wiring of the Microbeast. For maximum safelty hot melt glue can be applied to the plugs. This should not be done until after the fi rst test of the Micro- beast to make sure that all the conectors are plugged in correctly.
- Page 46 For a clean wiring installation fi t a cable pad D342 on the left frame side as shown. Bunch the wires together over the pad with a short cable tie D316. Lightly tie the wires together. Do not apply too much tension to cable tie.
- Page 47 Position both antennas symmetrically over the rear plate. This position is very important on the Heli- Baby because the CF rear plate will shield the receiver from receiving the control signal. Now place the P-clip D348 on the left front hole of the receiver plate as shown, with hex screw M3x8 D197 and a large washer M3 004...
- Page 48 Screw the seat to the rear plate with a slotted screw D343 and a nut M2 S010 by hand without Loctite. Do not use Loctite on the six seat screws as access is required to the radio system. Next drill the hole on the lower right side..
