Hi guys,

I'M HAPPY my new scale arrived today from USA...

I been dreaming with the AS350 by Century since the past year when saw the one that a friend mounted, simple the best and most beautiful scale fuselage ever, plenty of details and quality, simple amazing.

I will not make any external detail, simple don't need to add nothing.

In the box was the body, the three blades rotorhead, the whole scale mechanics by Century and the kit to make the conversion to electric, this last is really nice because you use the motor directly to the main gear or use the clutch, I will make the last option.

At the end I pretend this:

Open the front doors to better access to the battery and because I want to make the detailed cockpit with pilot.

Install the Diamond Head with scale painted blades, will cut the tips of the blades to improve scale look, straight tips like the real one.

Convert to electric with clutch, is amazing the slow spool up of the blades and the sound of turbine of the electric motor, very realistic.

I will post all the mounting steps, the setup of the mechanics and details of my own modifications ( doors, lights Etc Etc)

hello Doc,

Big YESS. I will keep this topic updated with the building.

As well I will need your help to, you have experience with the Diamond head, any tip will you have I will appreciate.

At first want to mount without Stabis, what your thoughts ??

To the motor/speed set I have an Castle HV85 and two motors, one Scorpion 4025 and one Align 650L, I like this one, of the Align ones is the best, I used them in a conversion of the same mechanics in Airwolf fuselage, Century to.

This is the video of the conversion...

a few photos of the mechanics, the cluth and the kit to convert to electric, I want to use the clutch.

This is the Electric Conversion Kit, note that you have a pinion and a shaft, so you can have two options: use directly pinion/maingear or adapt the clutch.

this are the clutch parts and the three blades swash plate ( that is a nice idea of Century offer scale mechanics, included scale rotorheads).

this is the Diamond Head Three blades rotorhead.

thi is the frame, already with the fuel tank and others parts for nitro engines.

Yup, she's a well designed fuse and you can't beat the price of the scale mechanics and 3 blade head combo. IMHO, I would not make the doors open. The design of this break open fuse really doesn't lend itself to that mod. But if you do, I would do a lot of reinforcement to the fuse before cutting the doors out. Extra layers of glass, some carbon rods to help support the cut out sections etc.. Besides, you have great access to the cabin with the break open front section.

I'm trying to finish mine up. I have the mechanics set up in pod/boom configuration now and will be putting them in the fuse soon.

All helis and planes have an expiration date stamped on them...you only find it after you crash!!

hi Mojave,

Nice to see you already had the electric conversion, what motor and speed are you using on it, please, pass details on KV and Wats of the motor.

In The Airwolf I used the Align 650L with 1220 kvs, and the original clutch with Align 75 Amper Speed Control. The flight time up to 7 minutes and no overheat in battery,motor and speed.

But the Airwolf have only two blades, maybe the new rotor need a better motor ???.

About the doors, I always do this mod in my helis, I apply three layers of fiver cloth with epoxi resin, and to avoid flex points I use hard wood ( conpensate) with 3mm, to cut use the Dremel tool, not even need to repaint in most cases.
The hingues are scale custom made in Brass, this is important to the doors open without force them and the fuselage.

I will post the complete step by step of this mods, and video to.

for my 50 size 58D, i use the century 80/110 amp esc and century's 800kv motor, this is withthe 4 bladed head. onmy lakota, i use the same esc and this time the century 565kv motor and have run it on 10s and also 6s with good results. (different throttle curves for the different voltages) last time i hooked up the 10s power though, i heard a pop when i advanced the throttle and the esc stopped working. no smoke, just a pop. i am using my backup turnigy esc til i get another century esc for it but til then i can only go up to 6s but it still does well. with the 6 s power, i have the throttle at 90% to get the headspeed where i want it. with 10s i had the throttle setting at about 70% to get the same headspeed. both gave me time in excess of ten mins. the 6s is run with 2 pax in parallel while the 10 s power consists of two 5 cell pax at 3000mah each run in series. the clutch option of course is used as i believe that s the only way to do a scale setup now. i have found that the lower kv rating motors make for a cooler running esc, more torque and longer run time. stilllearning the electric thing though. my cobra has a 400kv motor and am running a 6s batt with everything running cool. course that may change as weight from scale detailing increases,may go to 10 s power then. will see.

I have a Kontronic Tango 700kv motor running on 6S, with an HV85 esc, for a 1600 rpm head speed with 3 blade head. Copter doctor has a winning combo also.

Hi Emile,

I see you guys prefer lower KV motors, I assume you are using pinions with 14 to 18 teeth with 6S and 13 to 15 with 10S, or something close to that.
With 1100 to 1200 KV's I use 10 teeth pinion with 6S, this give me a head speed around 1500 to 1600 RPM maximun,a flight time up to 9 minutes for 5,5 kgm heli with five blades head...Century MD500 Defender + penta rotorhead with 600mm Carbon Blades...

Now I will follow your setups, I have a Neu Motor 1910/1.5Y 650 KV's to use with 10S, will test this one with 15 teeth pinion runing on 6S to test, I think the head speed will be 1350 to 1450 with three blades rotorhead/600mm blades.

Mojave...what pinion are you using in your set motor/speed to reach this 1600 KVs, did you tested lower HS with that motor??

I started to mount the mechanics first, in the fuselage there is almost no need to do, just install the mechs, lights and open the doors.

The Scale SE Mechanics from Century come with the tank, cooling fan shroud and shaft start, this I will took off because I want to use the electric conversion kit.
I removed the lower right frame only.

To remove the start shaft need to loose the collective arm first.

I dismounted the start shaft bearing block to use as reinforce in the upper part of the frame.

Next step was mounting the mainshaft and rotorhead, nothing difficult here, just follow the manual.

----------------------------------------------------------------------

I'm running the stock Century scale mechanics, so no gearing choices were offered. I'd have to check the tooth count on the clutch.

Hi Mojave,
Thanks a lot, your last reply help me to decide what set motor/speed will use, I started mounting the electric conversion kit.

In the photo the Neu Motors 1910 650KV's will run at first with 6S to testwith lower HS, I think 1300 to 1400 RPM's, just to test how the heli react.

I'm waiting for a new FBL, in the mean time I will use the old Gaui 365 I have, because work with 1 servo collective.

Indeed, very detailed, you will see in the the final video, lot better, I have on TT fuse to, better detailed and bigger to...take a look..

And a good new is a friend here in Brasil who already have this fuse send to me link with photos of the real HELIDUBEI scheme...

you should be ashamed of yourself promoting Heli Porn, I am drooling over my screen just now!

Beautiful fuse to start with and if I know you, stupendous when finished!

HAHAHA thanks Roddy

Working hard on this beauty, see the progress below...

I mounted the electric conversion kit of Century.
The motor is an Neu Motors 1910 650KV running on 6S ( will test with full load tomorrow if work)
Castle Creations HV 110.
I tested in the workbench, all ok, I made a video of all this steps, later will post a link.

Now that I finished the mechs is time to work on the fuselage, starting by the doors.
I used three layers of fiber cloth with Epoxi Resin, I do this mod in all my helis, work nice, light,strong and durable.

...after cure the Epoxi Resin I start to cut the doors, note that I will not paint after this mod, so I need to be very precise, any mistake will be costly

The Dremel tool with the 409 cut disk are perfect for the task...

...to make the door jamb I always use 1,5mm light ply, easy to work with. glued with medium CA and hardened with thin CA...
