    Built my scale EC135

    My most satified and easiest scale built so far.. although I've only been through 2 scaled fuselage, but they were both of Polycarbonate material.




    This EC135 from Align's 450 scaled series is of fibre glass and came with pretty much very details.
    It is pre painted in bright stunning yellow and all I did was to spray smoked black for the canopy and windows.
    Otherwise clear panels are OK, except I didn't like the look of windows showing those ugly LiPo and wirings inside.

    First out of the box I notice there was nothing much to install. But working into the installation progress, I realize I need to somehow cut a curved slot for the tail wings to be inserted through the tail. TOUGH !




    Then came the next step which i was instructed to dismantle the head and rotor so that the mechanics can be inserted through the opening. It had to be rotated about its axis 90 degree sideways, insert through the front of the fuselage, once 1/2 way in, rotate upright, push through the boom and then slightly wiggle its way for mounting onto the balsa stands.

    But I didn't follow that step because I was too reluctant to disassemble the head and rotating the mechanics 90 degree here and there didn't sound right.
    I chose to cheat and cut a slot at the top of the canopy so that I can split and pry the canopy up to slide the heli mechanics into the body in an upright direction.
    It works nicely. Within minutes I can position the mechanics inside the fuselage. If I were to dismantle the head, I may take more time need to put the head back. Hah !

    And luckily I did that cheat, because thereafter I realize I need to remove the mechanics in and out several times from the fuselage to adjust some stuffs here and there ; belt tension was loosen to my liking, check all screws all over again, reposition my ESC for C. of G. etc. It was much easier.




    Next came the lights. I didn't want to get to the Receivers port to connect the LED because I was worried of current loading and of course the dreaded removal of the the heli mechanics again !

    So I installed a small 380 mA Lipo for the sole use of the LED navi lights.
    LED system came with 3 types of mode, solid ON, flasher and slow beacon glow.
    Remember, Red for Port, Green for Starboard.




    All up flying weight is 1030 grams. Not to my likings but its manageable.
    Still running a pretty slow headspeed, but I have no idea how fast it is actually spinning.
    Need a RPM gauge, but no money to buy LOLX



    Some tips that I've worked around, such as charging my spare LiPo that's used to power up my navi lights, and how to access my Robird G31 flybarless system - I connected a short USB connector to the Robird's mini USB port and left the other USB end somewhere near the bottom access hole under the heli belly. Also notice the LiPo's connectors that I will be using to power up the navi lights. During flight, these cables are tucked inside. No problem at all, as long no violent stunts, all cables will stay where they are inside.




    Here is a short video of the maiden.



    Can't control heli very well yet, still at noobie level.. but as long don't crash, come back one piece I'm satisfied.

    i'll be honest...it looks damn nice!

    Mikado Logos, RaptorG4s, X7F, 600ESP...
    JUST one more Logo...for the month.

      Very nice indeed. Can share where you got your navi lights. I am thinking of putting my trex 450 pro in the same fuselage, n eventually converting to a 4 blade head, but still long way off.

        Navi lights are from Zenmtech.

          Bro, where did you buy the scaled fuselage? I also want to buy one for my Trex 450. Thanks.

            Both Zenmtech and rotor hobby should carry. Else online.

              Thanks guys. I prefer to fly scaled heli because they look more realistic. I don't really fancy flying 3D.

                Same here.

                I started flying as a scaled fuselage too.
                Although its nice, but flying scales need a little more patience because once you had to remove the fuselage to access your frame / component once too many, its becoming a hassle. Then the fun dies off.

                I am not discouraging, but that's one extra thing that need to work out when I started to put scaled fuselage onto heli.

                But it does really look gorgeous when my Cobra takes off and skimmed the tall grass, fluttering them, and staying low to break the silhouette from the skyline !
                Again, nothing fancy, just slow gentle flying

                  Normally, it is recommended that u have working heli 1st before u put it to scale. In other word, test fly your heli 1st and tune to you liking. Then when everything is working, u then put in the scale "dress" on it.

                  But if your scale are those whereby the heli is part of the scale (or the heli itself required the fuselage in order to fly it), then no choice but to fly WITH the scale 1st. U can test fly it with the minimum scale part assembled/installed.

                  Another recommended idea is that, put all your electronics (avionics) in front of your heli or in the place whereby it is easily accessible compartment (without removing the heli to tweak/fix it). Even the tail server can be reroute to the front (but more task required in order to build a custome servo mount).

                  Scale heli tends to be tail heavy (due to the "extra" parts on the tail). So, by putting all stuff in front, it also help balance out the wait (so u do not need to add extra weight in the frontal part.

                    Yes you are right.. always make sure Pod and Boom is flyable first.
                    But there are times where you unfortunately really no choice but to access to just 1 single item , or 1 screw, that's really no choice. LOL
