Parts Arrived!!!!
The only thing faster would have been for you to take a 1/2 day off work and drive to a LHS, picked up your "goodies" and drove home on Thursday, and you would hav had to wait till tonight to work on it anyway!!!!!!!!
Now that is service... and after meeting John, this guy looks a lot like him:

I was out flying mine today again, after helping mow that field.... and I like it even better then before..... and I haven't changed a setting yet.... this is a tough act to follow.....

Test Flight
Got the Tiger back together all but painting the tail fin, Just had it out for the test flight. Seems to have a vibration, the vert. tail fin shakes at idleup1. I never saw it do that before. Think it's anything to be concerned about? Other than that, I noticed a more aggressive vibration coming up form idle to center stick . It seems to go away when the engine clears out and tachs up. I adjusted the tracking, it's perfect. I'm also running carbons so I don't think it's the blades. If it's the mast, it cant be bent much, I did everythng short of pulling it out and rolling it. Any ideas?

You knjow what the right thing to do it! Pull it and roll it. Checking shafts is always done most easily by rolling it on a mirror, or piece of glass, to verify it's true. If it's bent you'll easliy see it wobble, or listen for the telltale tick, tick, tick indicating it's bent as it rolls across the glass.

There are but three critical shafts on a Tiger 50, the most delicate is the feathering spindle, or spindle shaft, which connects the blade grips. This 5mm diameter shaft is both inexpensive to replace and the job is easy to do. Not checking one after a hardish arrival (which both broke skid legs and bent the tailboom) recently cost me a bad crash later. It's because I was stupid and got in a hurry - again (I had neglected to thighten the tailboom in the first place which is what originally caused me to have the emergency leading to the hardish arrival in the first place). Anyway, I both broke my heli in front of folks (which was embarrassing) and it also forced me to re-learn the lesson about being lazy and not checking shafts (the very point of this little discourse since occasionally we all know the right thing to do but feel lazy and want to take the short cut).

The other two shafts of note are the tail output shaft (also 5mm in diameter) and of course, the main shaft (a hollow 10mm diameter shaft - did you know a hollow shaft is not only lighter and more expensive to make but it's real purpose is it's harder to bend than a solid one?). Anyway, servicing the tail output shaft is also easy. By just pulling three 3mm bolts holding the sideplate to the tailcase proper the tail output shaft is immediately accessible and turns out to also be duck soup to service.

The mainshaft is a little more difficult to service, but not by much. First undo the bolt at the bottom of the shaft (the one holding the autorotation clutch in place). Next, lift the whole assembly (mainshaft, swashplate, washout, head) off the helicopter - but not all the way out. Once it's loose, I slip the bolt holding the autorotation clutch back in place temporarily. The only reason for the extra step here is to keep from maring the shaft with a set of Vicegrips. I.e I'm using the head assembly (wrapped in a shop rag) as the handle to first loosen the shaft from the autorotation unit followed by loosening the head from the shaft. Since the swashplate and washout are a loose fit on the shaft and aren't an issue.

Anyweay, next I remove the Jesus bolt (the one holding the head to the mainshaft) and I pull the head assembly loose. Then, I loosen the setscrews on the shaft collar (between the swashplate and the upper bearing) and remove it (unless the shaft is really bent in which case it's harder to pound/pry off), and finally, I re-remove the bolt holding the autorotation clutch in place and finish removing the shaft.

If I know for sure I bent the shaft, I jump straight to pulling the head and then I grab the shaft with a Vicegrip and using a hammer to tap the side of the Vicegrips I pull things loose.

By the way, I may film the procedure and post it on the website. But folks, before I divert my efforts to this, is there any interest in seeing this done, or is it clear enough from the description?

John
Explaination sounds pretty straight forward, I tend to just pull the Jesus bolt and pop off (2) ball links and remove the head, then I put a black handled driver through the Jesus hole where I just removed the bolt and use it for leverage to pull the shaft out after I remove the autorotation bolt, that way I don't put any unwanted pressure on the head assembly and I can use a twisting motion if the shaft has a slight bend in it.

I definetly agree that if you have a shake, pull the main shaft and also double check the spindle, as John mentioned the time spent checking could save a failure in the future, remember these little guys are spinning the head around 1750-2000.

I spent an hour with my gasser just getting the run out to .002 on the fan and clutch and it's paid off with a very smooth machine.

Tigers & Newbies....
I'm probably not the typical beginning chopper pilot.... because I have been flying fixed wing stuff for over 40 years.... but I thought I would share my experience with the Tiger 50.

John Beech sent me the ARF version.... I had the radio and engine into it in about 3 hours.... I've been playing with helicopters on a RealFlight G3 simulator since Christmas....

And, after overcoming my cheapness and pulling the cheap engine that I originally installed, and replacing it with an O.S. 50 (Not the Hyper... just the "Mere Mortal" version....) I am happily hovering around my back yard. (Oh yes... I had to take a side tour, and try to fly a brand new 6 meter receiver that some helpful soul had stuck a Channel 45... 72Mhz crystal into.... Don't bother trying it... it doesn't work!)

The New Mexico Spring time breezes are blowing... and the Tiger rises up a bit in the breeze, but basically everything is under control, and I am ready to take it out to a larger space and start flying around.

So... totally unassisted (except for watching John Beech's "Hover" video... and reading Ray Hostetler's book).... I went from Chopper Virgin.... to "Not
Quite Chopper" virgin.....

Bottom line.... I am having an awful ot of fun with helicopters... and don't see what all the fuss has been about all these years! :-)

Welcome to Heli's
Hi Talyor,

I too have been flyinjg RC planes for a long time.... first radio was in 1969 and before that I flew U-control..... and I still have a very nice fleet of planes....
But the heli's, that I started flying in 1991 have taken the front seat... and in a big way.... I still always have a plane with me and most of the time will get 1 or 2 flights on it in a day, just to stay in "shape", but nothing like the heli's...
I would have to say that the equipment that has become available in the last 3-4 years has made it so much easier to learn to fly, and for the heli to act like it really is controlable. There is no reason not to try one now... The sims, books, videos, excellent equipment, and guys like John,all make this incredible part of the hobby a lot easier to get into...
The set up you have now with the G-3, the Tiger and an OS 50 is probably the best and easiest way to go, plus when you are ready to go to the next level, it is all already there for you... you only need to change a few basic curves in your radio to go from mild to wild!!! It is sort of like have all the "stuff" on G-3 already in your raido, just waiting to come out and play!!!!
Well, I have rambled on long enough (you know how us "old" guys like to talk!!) best of luck and have a GREAT time.... it only keeps getting better.. Stan
