Cypher 50

Galifrey

You spoke previously about reversing the Tail rotor grips.
Because I'm new to this hobby and that I have just received my Cypher, could you explain what this means?
Thanks

The tail rotor control can be either leading edge control or trailing edge control (the side of the tailgrip the control ball is on)

Hope that helps

After comparing your photo, I now understand.
Looking from the top, the ball link faces to the front, not the back as they have set it up.
Hope this is right.
Thanks again.

Cypher 50 newbie !

Hi All ,
I ordered my cypher kit two days ago withou any idea what qaulity of heli I'm buying . Only after I bought it it started searching around for reviews . After reading this whole kit review I'm convinced ... I bought crap ! ........No , just joking !!! I think I'll be very happy with it !

I'm comng from a JR background having flown the Voyager 50 and Venture 90 both engined with OS .

Can anyone tell me what to expect from the Cypher when comparing it to the Voyager 50 ?

In the grand scheme of things I'm waiting for YS to launch their 50 engine and hopefully it's compatible with the cypher so I can stick it in there ...

So guys keep those upgrades info comming , I love it ... more gadgets for me to tinker with ...

A club mate who also purchased a Cypher from Cyberheli, said that at
Sandown he saw that someone is importing a heli which is basically a
Cypher.He said that it is available as a 30 of 50 size, but with some detail changes over the Cypher such as an improved tailcontrol linkage,
so hopefully spares for the Cypher will be available locally.

I had my first heli crash in eight years today!I guess that I was due one,
but I am pleased that the Cypher is only lightly damaged.A carb retaining screw came out and caused a flame out, my own fault for not
puting some locktite on it.Anyway, my home made auto unit worked,
but I had to auto downwind from twenty five feet up onto concrete and
although the touchdown was light the rubbers on the skids grabed the
concrete and fliped the Cypher over.Damage is, tailboom ,tailboom supports, tailrotor output arm, two mixers on the head, flybar and feathering shaft.Suprisingly, the Hi-Products blades, which must have
hit the boom, don't have a scratch on them.
Anyway, before the crash, I had a nice twenty minute flight with the Cypher.It tracks very nicely through loops and multiple rolls to the right,
although a little slow, are very axial.Rolls to the left require a little correction when inverted to stop the nose pitching up.A roll takes about
two to two and a half seconds.Stationary rolls and flips are no problem
if a little slow, I may fit some lighter paddles to speed things up a bit.
Last Thursday I flew the Cypher in a twenty to twenty five mile per hour wind, and it handled it no problem at all, in fact the Cypher is so stable
I had doubted wether it would even be capable of a roll or loop!All in all,
I would say that the Cypher is a great addition to my heli fleet.

Sorry to hear about the crash , but you would probably be able to tell us later on what effort there is in getting parts for the machine . I finaly got my Cypher from Cyberheli this weekend and I'm itching to get started ... I still need a motor and a pipe , any news on the YS50 yet? I'm a bit broke this month so I'll wait till next month to buy the last remaining bits .

The kit itself looks good and I'm pleased with it so far , but I have one question though ... I read previoulsly in this review that the swash plate alows you to choose between 120 deg or 140 deg . Where and how do I do that and is the parts included in the kit ?

Thanks!

As far as I am aware, only 120 degree CCPM is catered for in the kit.
The swash plate does is drilled and tapped for other cofigurations, but
I assume that it is intended for use on other helis as well.My Cypher is
just fitted with an old O.S.46FXH and Yusa muffler running on 5% nitro
fuel.I was considering fitting my O.S.50 but the model has plenty of power in its current configuration, and as it has no thrust races in the
head I didn't want to increase the headspeed.I have a set of Hi-Products 585mm blades fitted, which originally were purchased for my
TSK Mystar heli.With these blades, and the O.S.46, I am pulling +- 10.5
degrees of pitch with a headspeed of around 1700 rpm. I will have a final look over the machine this morning and then order the new parts.

Hi Nivlek ,

Would you say that the head without any thrust bearings could become a problem later on ? I do intend to at least put an OS 50 with 600mm blades in and on the machine (by the way , you do get blades with the kit unlike what they advertise on cyberheli) .

Should I start out with putting thrust races in right from the start?

Thanks !

Part for the Cypher 50

Jan the Man

I ordered parts from iron.helix@msa.hinet.net using Paypal and received them in 3 days.
I first sent an email to find out the price and shipping then used Paypal (http://www.paypal.com) and that was it.

The reason that I didn't use the blades as supplied with the kit is that the
plastic blade thingies that make the blade fit the blade holders, were missing from my kit.If the lack of thrust races would be a problem at higher headspeed , I don't know, and I didn't want to be the person who found out!Obviously the manufacturer did not think that they were required, and during my first hover I had a headspeed of around 1900 and had no problem.I have always been asumed that thrust races were needed simply because they are generally fitted to machines of that size, but unless you happen to be able to work out the amount of pull on the blades and know the maximum side load that the supplied ball races can take it is just going to be a case of "suck it and see".As Cyberheli supply a deal consisting of SAB blades and an O.S. 50SXH, they obviously think that the machine can handle it O.K. so maybe it is worth a quick email to them to ask their opinion.

P.S. When it comes to my models, I always err on the cautious side.

Cypher rotorhead

I took a closer look at the Cypher's Rotor head . What I saw that looks weird to me is that there is some play on the blade grips . It slides up and down on the spindleshaft and you get quite a gap between the rotorhead and the blade grip . Is this normal?

I also tried to repove the blade grip by undoing the locking nut on the spindle shaft , but the grip didn't want to slide off ... has it been lock-tite in there ?

I hope you guys have an answer for me , or am I being paranoid ...

Thanks

I didn't notice any play on my head, but I wasn't looking for it.The feathing shaft came out on mine O.K. , it is still apart waiting for the new bits.By the way, the spares prices from Modelbits seem a little high to me e.g. upper mixer arms £6.95 each, flybar £6.95.Maybe this is not too bad, having gone so long without a crash I am not in the habit of buying a lot of spares, but it seems expensive to me.

Jan the MAN,
I received the replacement parts today, but they are for the Voodoo not
the Cypher so have slight differences.The gap beetween the threads
on the new feathering shaft was 83mm instead of the 80mm on the original Cypher one.So the new shaft was put in the trusty Myford 7 lathe, turned down and then threaded so that it was now 80mm between the threads.When the head was reasembled, as you noticed,
there was a lot of play.So the shaft was put back in the lathe turned down a little more at the end and threaded again.This time the shaft
is 78mm between the threaded sections and the play is just a few thou.

The Voodoo flybar is just 390mm instead of 540mm on the Cypher, indicating a different paddle blade attachment i.e. the flybar does not go all the way through the paddles on the Voodoo.The upper mixer arms came complete with bearings which explains why they where £6.95 each, however just supplying the plastic arms would have been preferable, however there is no excuse for the flybar costing £6.95.
Had I have known that the new flybar was going to be shorter anyway,
I would have grabbed any old 3mm flybar for £3.The ratio is slightly different on the new mixer arms, with the longer side now being longer by about another millimeter, but I can't see this small a difference being noticeable.

You can also use the JR 50 series (60060) flybar on the Cyper . It's an exact match . I found the flybar that came with my kit has got a dodgy thread job on the one end . I might end up using my spare JR one instead

While I'm still haven't started building mine I'm chekking all the parts against my Voyager 50 and Venture 90 to come up with some matches .

I guess what you guys call a feathering shaft , we call a spindle shaft . That 83 mm shaft is the match again for the JR Voyager 50 spindle shaft (60068) wich is as you said 3 mm loner than the cypher spindle shaft .

I removed the play from my cypher's head with a shim in each of the grips (I don't have the lathe option unfortunately) . Now I only have the blade grips that slide over the bearings . Any ideas how to fix that ?

Sorry I don't understand what you mean , you'll have to help me out, I'm a little slow.After I shortened the shaft I had no more problem.
We use the terms, feathering shaft or feathering spindle, so spindle shaft is a cross between the two.
Thanks for the part numbers on the JR bits.One mod that I am concidering, is to drill out the flybar carrier to 4mm, replace the bearings with ones with a 4mm id, and fit a 4mm flybar.I have more
paddles that require a 4mm bar, so this would give me more options
to play with.
