Hi Steve welcome to the forum. I can't help you with your problem but just keep bumping your thread to the top and I'm sure someone will have the answer. I can help with any issue on the King though, my first hovers were with a King 2 so fondish memories

**steve-** · 29-07-2012, 10:40 AM

Hi and many thanks for your support, I found the King 4 very different to the older models that i flown in yesteryear, the size and weight being the main issue where has the larger nitro models being much heavier therefore quiet stable in the hover, with the main blades being about over 2 foot in length each and a cord width of about 2 inches they made sweet music when flying. got my King 4 a few months ago and all seems to be okay, i started out with a Hirobo shuttle which was on eof the first ones with astandard 28 sized Os engine and i think the whole thing was pre assembled other than the blades and stickers and then placed and standard 4 channel areo radio along with a Quest gyro which i still have 2 in working order.
But the main issue with these heli's are the repair costs, even for a small crash would cost you a small fortune, but with the Esky parts are very good allowing you to be more adventureous!

I would be interested in seeing pics of the mechanics with rocking servos. I am not familiar with Graupner or Heim so the only system using rocking servos I am aware of is the Robbe system 88.

You may find something useful here; Vintage RC Helicopters - Heim

Hi Trillian

No problem i will photograph my Bell 222 which is pretty much intact just remove the mechanics / engine for a service

Hey.

I'd give Dave Wilshere a call at Motors and Rotors, as his shop in its former owners hands (Vago Nordigan from memory, which is going back many years) used to be the Heim distributer from memory. Also as Dave was a Graupner dealer (very similar to Heim) he may be the best person to try I'd say.

Hi Coolice that mega many thanks, Just turn out all my Model Helicopter World mags make real interesting reading, My Bell222 is a Graupner Heim, but i think the Star Ranger is a Vario of sorts as it has a slightly different frame for the machanics and there are red ball joint holders etc, where the bell 222 are all black.

**electricsceadu** · 29-07-2012, 02:53 PM

the star ranger uses 2 servo eccpm (yes 2 servo)
the pitch servo pushes the aileron servo to increase/decrease the pitch
there is a silver one on the bmfa web site for sale with the top off showing the servos
i don't have any photos of mine with the top off (i don't think i've got any of the whole heli)
and if i remember correctly you could go direct eccpm onthe servos like the graupner uni-mechanics and the vario skyfox
with the skids go for the graupner or vario 60 size jet ranger ones
motors and rotors
and
martin briggs models
are the dealers for graupner in the uk
martin has retired but he still advises the new owners on anything techincal that they can't answer

with the star ranger make 100% sure the top sero try is in good condition as the one i have the ply wood broke around the one servo in flight which made a very interesting landing (and un-damaged), i reinforced mine with an ali plate screwed ontop of the wooden one

and the other option on spares is the vario sky dragon and skyfox models but check the shafts sizes you have as the vario ones uses different dia's on some models

and don't do what the last owner of mine did
he ripped out the cooling duct and tried to fit the later uni-mechanics into it and made a mess of the internals of the body shell
but i can't complain as i was given the body shell and the profi mechanics set

Hi

many thanks for taking time to inform me of the details in your post, The machanics do differ a little from my Bell 222 and like you say there seems to be a position on the frames for 2 servo's, the tail is mounted on the inside behind the bulk head at the rear the throttle looks like it will be mounted on the front upper RHS plywood section, but another i think does forward a aft?
The items i think are missing to complete the build are 2 missing struts for the landing gear, and the exhaust system, other than that it is complete, Could still do with some plans for linkagesetup etc.

Again many thanks for your support and comments and i will have a look at teh site suggested for the view of the servos

Hi just had a look at the BMFA site with reference to the servo arangement. It is the same as my Bell222 therefore using the rocking servo system, but the frames used in the Star Ranger are slightly different and looks to install the servos on the frames rather than the rocking system

**steve-** · 29-07-2012, 05:05 PM

Hi Just thought i take a picture of both mechanics. the left hand one is off the Bell 222 which i know is Graupner heim, the RHS one is for the Star Ranger and you can see the slight difference between the frames RHS being the one for the direct servo mounts?

**electricsceadu** · 29-07-2012, 07:43 PM

the bell cranks are the clue
they both use the rocking servo layout
i'll dig my old set of mechanics out with the webra 91 installed to remind myself of the set up as this set had the rocking mount missing and was set 3 servo 90 deg eccpm

**steve-** · 29-07-2012, 07:43 PM

Hi Just Googled Motors and Rotors, comes up with web site not fouind and body got a contact number?

**steve-** · 29-07-2012, 07:54 PM

Hi Again
I seem to remember distantly that when i was constructing my Bell222 i had the option of the rocking servo or mount direct using i think Y leads, i also seem to remember that a mate of mine who also purchased a Bell 222 also purchase a pod and boom set-up which you basically attached the machanics to teh shoe box and use the Y lead configuration, not 100% sure about this though is was a few years.
So waht you are saying on both types of machanics i have photographed would still need the rocking servo? the reason for asking is that there has been on allowance for the rocker etc in the prep work which was carried out by the person i purchased it off serval years ago.

**trillian** · 29-07-2012, 08:18 PM

I just saw the one in the BMFA ads so I can see easily how they did the collective via rocking the aileron servo.

In the back of my mind I'd like to have something like a Jet Ranger fuselage that I could fit Robbe Futura mechanics into but I don't know how practical it would be for me to carry around.
