Good News:
Well after spending about 3 - 1/2 hours trying to get my fan hub dialed in I settled for .002" run-out, thought this might be OK. Today i started it up and the fuel looked like bubble bath before I ever got the rotor speed up to lift off. I shut it down, tore it down and the hub was off .018" Every time I thought I had it, it would change when I tightened it down. After enough tries I found the problem. The collets were going in deeper each time because the hub is so soft it's stretching to a larger diameter as I tighten down the hub. It final got to the point the hub was hitting the front of the engine. Well at least now I know the problem.
Bad News : Nobody I've found lists these parts as available yet. I need PN's 110-172 Fan Hub, 110-175 and 110-174 collets.
If anyone knows where to get these PN's I would be very appreciative.
Thanks

You really should have those parts replaced from your supplier.

I had a similar problem. I've had my Synergy for a few months now. I had my fan dialed down to 1.5 thousands. When I got it into a hover the heli vibrated pretty bad so I ripped the motor out and found the hub to still be at 1.5

Two tanks of hovering later and still no luck.

I then went to start it again and the motor wouldn't turn over but the hub and fan were turning. It turns out that my motor shaft nut backed off a little and my lower collet was slipping. I took it apart and my lower collet is completely fried and gouged out. I haven't been able to fly for at least a month because of a $5.00 part that noone has in stock

And I'm not about to order a $5.00 part from overseas.

So if anyone has a spare lower collet please pm me and I will pay for the part and shipping. I've had it on backorder from Ricks for a looong time and I've been patiently flying my other helis but I'm done being patient now.

Call them directly and keep calling them until you get the parts you need.

To hover is divine, the alternative is rather PLANE.

there is hope, quick uk are making these bits. the sooner the better.

it might be worth a call to quick uk for your parts. they might be able to help, or try realraptors in uk if synergyrc can't do anything.

cheers

I had a similar problem the other day when dialing in a hub for one of realraptors customers...

The lower Colet was just not the same shape as the opening in the back of the fan hub, the angle of the taper was a few degrees off.

You could get it dialed in but when you tightened it down it would just go right out and show up as a line about 5mm from the top of the Colet.

The fix was for me to slightly re-machine the lower Colet for the correct angle and it then went on perfectly (1tho run out).. This was with the newer collect too (slotted)..

If your still after the parts then i know andy has them in stock (www.realraptors.co.uk)..

Cheers

Good News , Bad News UPDATE...

Just got off the phone with Todd and not only is he replacing every part no hassles, but he offered to install and dial in my hub and clutch for me. All anyone can ask, because as we all know EVERY manufacturer has issues. What's important is how they are handled.
Thanks,
Todd

I have talked to Todd several times with minor issues and he is always willing to help you out anyway he can. I just don’t get why some people have said that Todd would not help or work with them on any issue!

Yugi

If you keep doing the same thing…...you’re going to get the same results!

Shame we haven't got our own Todd in the UK!! He mailed me his # but international calls are expensive in the UK and i don't expect he would have popped round to dial my fan in!!

Good/bad..

Talk about great deal of help...
I have never had a fan nut thread out on me.. red lock-tight dose the trick providing of course you use a piston locking tool.
As far as dialing it in there are different ways to do it. lots of wrong ways and one right way (thanks Hans).
I too have had Tod work with me for a few hours on an issue that turned out not to be a Synergy problem. So if someone comes along and said there getting no help from Tod I wouldn't believe them even if there tongue came notarised.
Thanks Tod.

whats the right way? wait on quick uk to make better parts i would say or if your lucky enough to have a machine shop to rework the hub.
qc is the problem on this thing atm, i've seen 4 synergys (2 are mine) and not one of them have parts the same specs as the others. i wonder how many places are supplying pars for this heli, if they are all from same location then whoever sets up their equipment needs shot or the tools/machines they use calibrated.

all these issues with this are easily resolved, they are not design ones but qc ones with whover is making the metal parts. i'm sure it's in the works being sorted out.

Be carefull when installing engine after dialling in. You need to get the top of the start shaft exactly in the centre of the frames at the top before you put the top bearing support in. The shaft is so soft it will flex to fit the bearing(which is centred by itself) and give you a foaming fuel tank.

I think one of the problems is that some people run in to an issue and cant resolve it and when others share the same issue everyone automatically thinks its a manufactures problem.
I too Just learned how to dial the fan and clutch in the proper way.
A lot of people just check it with the screws one way and then turn the clutch 180 to see which has the most accuracy.
You need to align the fan first so you put the fan on use red lock-tight on the nut and don't over tighten it. It should be just snug.
Then dial indicate it closer to the outer edge of the fan hub.
If its out use a hard rubber hammer and tap on the opposite side to try and even it out. (don't forget to reset your dial indicator).
Every time you get it closer to the to the desired position you tighten the fan a bit tighter. try measuring the inside diameter as well. do that about 2-3 times then tighten it completely with the piston locking tool. (double check it after its all tight if you did it right it should be perfect).
Then you you put the clutch on and just like the fan tighten it snug not to tight.
check to see which way it works best if not one way turn it 180 and try it the other way.
Once you have it as close as possible and snug you would repeat the same procedure as with the fan. Tap on the uneven side of the clutch to get it real close.
Tighten it some more and check it again till its within the 0.001 0.005 .
Once its tight on you can use a back end as a driver (hollow) or a hard pipe to bend the clutch shaft to get it to Zero. If its out one way bend it the other way.
I was amazed to see a Zero on the dial indicator.

let me put this very simply to you joker, it IS a manufacturing problem. do you not understand no 2 of these things are the same????? THATS the problem, some bolted right up using the method outlined by your good self and others, like me, spent numerous hours fixing it. i've never had a heli this bad to dial and i'm about to start my 2nd one

. with a change of luck it'll bolt on no probs.

i do know stu's first set of collets and hub was really bad and his second just bolted right on at 1 thou, he is a jammy twat though.

also anyone contemplating doing this i would give serious thought before using a piston lock on any engine, asking for trouble. toothbrush or the OS crank lock is best idea.

you think bending the shaft is the way to go, i would not do that but, each to their own.

cheers

It was bad enough dialling in the mickey mouse fan. But the clutch has only two ways to go onto the hub. Neither of these give you anything close to ok. I had to dremel out the inside diameter of the hub to allow enough movement to get the base of the clutch ok.

While we are on about the fan and clutch can anyone tell me the reason why there is not a shim between the hub and clutch ?????
I have taken mine apart enough to notice that the clutch shoes leave a mark on the fan hub where they are moving in and out to engage the clutch liner. Is this part of the reason why the pick up RPM is so high?? ie friction as the shoes move out.

There IS a problem with these parts as why would so many people who have been setting up helis for so long all be having the same problems.
If yours dialled in with no probs then I suggest you buy a lottery ticket as you must be the luckiest person in the universe.

I love flying it but hate the parts.

mine and everyone else i know that has a synergy (which is like 6 people) didnt have any problems dialing the hub. its seems to me that most of the problems are in the uk kits, or maybe you guys are just talking about it more.
