I am aware that Steve Evans has posted pics showing this, but as I was following the photo's I noticed that the helicopter in the photos was different to mine, I guess its the king1 or similar?
Once canopy is removed you want to remove the 4 small screws that hold the main body of the heli to the landing gear, (once they are removed you will need to pry the body away using a small flat screwdriver) the purple arrows show the location of the 2 screws on this side
(also undo the 2 on the other side) Next you will need to remove the 2 knighthead struts
See blue arrow.
Now the heli looks like its been in a bad accident, but worry not - the next step is to remove the old motor (re-attach the screws to it for possible future emergency use) there are 2 screws holding the motor in place (purple arrow) Also remove the esc cutting any cable ties that hold the wiring in place - disconnect it from the receiver, remembering which slot you take it from.
Ok now the hardest bit...find yourself a nicesharp craft knife and cut yourself a nice channel out of the motor housing, this will allow the new motor cable to run out from the base without hindrence or damage. I found it easier to use the knife to make 2 small cuts (as the plastic is fairly dense) then use a pair of needle nose pliers to 'twist' the plastic bit out, then use the knife again to tidy up the rough bits left - now try placing the motor in the housing and seeing if the wire snugly fits between the gap created - if not retrim and retry. See photo.
Now fit the motor in and screw in place with the screws provided, if not reuse the old ones
ensure the pinion is located snugly into the gear but not so tight that it will cause damage to the gear, and not so loose that it will strip the teeth off the gear. Purple arrow shows wiring exiting the channel you created. See photo
Reattach the heli to the landing gear using the 4 screws, leave off the knighthead stuts for now, as they will be in the way for the wiring and securing. Connect the respective motor wires (black red & blue) to the esc, now use a thin cable tie to secure the wires to the two servo's which are right next to the giro, look under the servo's and you will find just enough room to slip it through and secure. also note that in the next pic you can see a better view of the motor wiring exiting the motor housing unit.
The next bit is up to you whether you do it or not, but I did read that its best not to have the esc right next to the receiver, so I cut a piece of plywood to fit in the rear section where the receiver is currently attached, (I know it won't stop interferance if there is any, but it also protects the receiver if the esc were to get too hot) and gives the receiver a nice flat surface to adhere to. Do not completely fill the compartment with the wood leave a small gap at the back so the cable ties can drop through. Run the esc wires down the landing struts and secure with ties, pass the 2 ties over the plywood and run under the heli, securing the esc to the underside.
At this point I unwound my receiver ariel and routed it away from the esc wiring (see last pic for route I used) See next 2 photos for details.
Connect the esc back into the receiver, and re attach the receives back to where it was, cable tie the big bundle of wires back to the main body (arrow 3 in pic), and cable tie the esc battery cable to the leg strut (arrow 1 in pic) Arrow 2 shows the gap left when inserting the plywood base into the receiver compartment - note how this allows the cable ties to drop through the base. See photo
Reconnect the knighthead struts to the heli on both sides. and route your ariel cable as desired
The photo here shows the finished heli complete with motor and esc.
Hope that is everything..... I didn't time myself doing the job but I would say it took prehaps 1.5 hours (guess) but who is to say how long it should take YOU?? the more time you take the better the job will be.
Hope this is of some help to you....Its certainly made me a little less scared of taking it to bits,
especially when its in two sections.
Best wishes Deano
