 Finished suspension arm. use 0.5mm diameter spring wire for 1st, 6th and 7th suspension arm, 0.4mm for 2nd, 3rd, 4th and 5th suspension arm.

Smoothen the surface of plastic tube for spring wire

Insert spring wire through shaft hole on side panel

Bend spring wire into the slot on plastic tube

Shorten spring wire.

Use protractor to set angle of each suspension arm 1st and 7th to 30~35 degree, 2nd to 6th to 25~30 degree 1

fasten torsion bar by hex socket cap screws

Do the same to all suspension arms

Road Wheel

For TAMIYA Kit, polish road wheel shaft a bit, put fit (B2), rubber tube,  glue rubber tube to shaft,

then fit (B3)

fit sprocket by hex socket cap screw

 For TAMIYA  kit, first to fit Hex cap to socket

 use 1mm drill bit to find center

 expand to 2.5mm by 2.5mm drill bit, then tap(3m*0.5) it

 fit sprocket by hex socket cap screw

 Electronics in tank hull installation

 Bolt TK35 board to TK35 fixture<D10> then glue to chassis

Put Volume control fixture<D7> on chassis and make 3mm and 1.6 mm hole

Fit Volume control to fixture

Blot fixture and volume control, then adjust volume by screw driver

Put Switch<D4> and fix it with switch fixture <D5> and bolt.

Drill hole then bolt battery fixture<D8>from bottom

Fit speaker next to battery fixture

 Lighting

Tail light, first to wire in-series 150ohm resistor to LED

Make 3mm hole then fit tail light led. 

Headlight , first to remove some coating on enamel-insulated wire and solder to SMD white LED

make hole on headlight part, insert LED assembly to headlight part

insert wire to upper hull

 solder enamel-insulated wire to 2-P cable

 Turret Rotation

 Modify turret parts as following

become this

Cut off tail section of lower turret tail, glue to upper turret hull

Glue magnet to upper turret support frame( Left ) and inner turret floor (Right), Put some drop of quick glue between upper turret support frame and upper turret, fit upper turret assembly to lower turret, adjust turret support frame to make sure up and lower turret fit perfectly before quick glue is cured.

When quick glue is cured, open lower turret, apply more quick glue to strengthen the bound.

grind the ring part then fit to turret ring 

fit blue gear to turret floor, mark the opening on turret floor, make same opening on blue gear

Blot blue gear on turret floor

fasten black gear on the shaft of geared motor by hex socket cap screws, the fit assembly to housing<E3>

 Glue housing<E3> to upper hull

 Main Gun

 Drill hole for MG light guide

fit gun breech to gun mantle

Remove tail portion of gun barrel

Drill gun barrel by 4mm drill bit

Fit Gun barrel recoil adaptor<F3> to gun barrel

Drill gun mantle according outer diameter of gun barrel

grind  Gun barrel recoil adaptor<F3> if it can not move smoothly when it's inserted into gun breech

Insert recoil servo arm into the slot on Gun barrel recoil adaptor tail and fit recoil motor on top of gun breech

Make 0.8mm hole on gun breech

the bolt servo recoil in the top right, bottom left and right corner

Make 3mm hole on the center of muzzle for LED, make 2.5mm hole on gun barrel front end for LED leads

Trim off the lip on LED bubble

Insert muzzle assembly

 Elevation

 Fit a screw on servo arm, trim servo arm

Fit servo to servo fixture<F9> and bolt it

Bolt elevation assembly to turret floor

Adjust servo arm angle till gun barrel can be depress to -10 degree and left to +20 degreer

can be left to +20 degree then bolt servo arm

IR receiver (Optional )

Trim IRM lead to 13mm,

Solder IRM to socket

Insert IRM assembly to IR battle unit housing

Glue IRM assembly and upper cover

Fit socket to IR battle base and glue it

 Fit IR battle base so that IR battle unit can be plugged smoothly

Glue IR battle base

 Pin assignment for wiring, S stands for HBU/TBU SIG on CN2-1 of TK35, - for HBU/TBU - and + for HBU/TBU +

 IR battle transmitter

 Insert IR emitter LED in to IR battle transmitter housing

 Solder cable to IR transmitter LED

Similar to IR battle base, insert socket then glue it

So that you can hook and remove IR transmitter easily.

All modification are done, refer to TK35 web page to do wiring.
