OK so it flies. We already knew that, but I have a few questions for those that have flown theirs and found little things to help it along.

1) Does running the OS 50 rich on break in cause vibration? I've got three tanks through it now.

2) Does the above also effect the gyro (gy401) tail wagging just a little?

3) What throws do I need to have on the swash to get any more speed out of the cyclic, or should I just wait until I have the engine leaned out some more so I have a higher head speed to gain faster cyclic response?

4) I was lied to! I didn't have a smile on my face until after I got the engine started (instantly) and got it into a hover. I thought it was supposed to be there before I got it airborne.

Other than those things (which are more setup and break in than anything) the Tiger is a great heli. Very smooth at this point but slow, even for me. The other guys at the field all thought it was a very nice heli. Some didn't even know about a 120* swash and were asking many questions. Of course now everyone else at the field flies Raptors and a single Caliber 30 so what can we expect!

Yesterday was a great day to fly here. 60 degrees and mild wind! Can't ask for more than that.

Smile'n!!!!!!

Didn't mean to lie to you about the smile.... just a matter of where John packages it in the kit....!!!!!
With 3 tanks, you can go ahead and begin to lean the engine a little at a time, and yes the rich running will cause your 401 to "bump" a little because it is not running smoothly yet....so start bringing the needle in a bit and start smoothing everything out...
As far as the throws, check for the max settings on your unit so that there is no bind... you may be able to move you swash throws up to 70-80% without bind and then use your dual rates to get the "feel" you like... and, yes, as you asked, the higher head speed will also sharpen things up quite a bit... are you still running the wood blades, stock dampers & fly bar and paddles??? If so get that registration card in and get your free up grades and that will also keep the smile going!!!!!
Best of luck with your new heli, and as far as the "rappies" go..... you will see some stay and some go..... we have one rappy left at our field now... maybe two....

Yeah, I was figuring on the gyro thing as I've seen some posts and thought I'd at least get a confirmation. Going lean on the needle, soon (next week). Yes I'm still running the stock heli. No upgrades at all (I think!) yet. I was just wondering if maybe I had something setup badly (probably). It does fly and fly's very well. I didn't do anything radical with it, but I did do some forward flight around the field. Once in flight it seemed to have smoothed out (or was it just my perception?). Yes I need to get the registration in and get those upgrades. I do want more speed out of the cyclic (don't need insane cyclic) so it doesn't feel so mushy even to me. If I can get it to be as responsive as the Raptor I have now, I'll be satisfied (until I'm doing more mild 3D). I'll be going over the Tiger this evening and see what I may have to tighten up and adjust after the first flights. I did notice one thing though. Do you notice that the blades get loose at the blade grips? I had to snug them up each time I flew the Tiger. Should they be "really" snug?

One other thing I forgot to post here is the low speed needle on the OS 50. Is the set screw that you adjust either rich or lean supposed to be as tight as mine seems to be? I tried to adjust it and it is so tight that it seems stuck. Do I need to loosen the pivot nut for it to move? Can't put a bigger screwdriver on it as it's a very small slot in that screw head.

It's Working...

I just checked my settings and I am running at about 75% on my swash throws.... and that will "crisp" up the feel... once at speed with the head and the engine running smoothly, you will be every bit as fast, if not faster then your exisiting heli..you can also play with your rates on your transmitter to get a faster response, but I would suggest you get everything else at speed first, then start to fine tune it, or it will change every time....
As far as the blades getting loose... it that is happening, change the nylock nuts.. and make certain that you have enough thread going through to catch the nylon... the blades should be set so they will fall if the heli is on it's side and you give it a quick jerk... hope that makes sense to you...
Idle needle... if you have to really crank on it then the nut has to be loosened a little and then adjust and re-tighten it... but again, don't adjust the low end until the high has been brought into where it has to be....
Good Luck and burn that fuel.... sounds as if we may get our first chance this coming weekend, and I am looking forward to flying outside again.... indoor is fun, but being able to let'm rip outside just is not the same!!!!!! hope John has a lot of parts ready!!!!

Thanks for the info. Sounds good. The weather here is supposed to be in the 70's this weekend and be perfect for flying. Hope to burn another gallon of fuel through the Tiger. Just picked up two more gallons. I certainly hope that it starts to get better fuel mileage as a tank every 8 minutes is rather high!

Go fly it hard Stan, we have plenty of parts in stock

Just remember -- if the world didn't suck, we would fall off.

8 minute flights? yeah, I'd say you're running it rich all right! Usually I get 11-1/2 to 12 minute flights. The main needle ultimately will end up around 1-1/2 turns from closed when it's broken in. Yeah, I bet your head speed is in the 1550 range if the engine is that rich. I like 1910 to 2000 RPM (not with woodies though, limit them to 1750 or so) for 3D and you'll be happier with cyclic response.

8 Minutes.....

WOW,how many turns open is that main needle????
I think that John's calculations are probably pretty close....
Go ahead and start to tune that engine... at 1 3/4 to 2 you will be plenty rich and at least you will start to feel the power... get that head speed up prior to any of the other changes though....

After flying the "rex" all winter, I will either look like a pro or mash the H*ll out of it....!!!! Either way I am going to have fun with it... always do....and I am READY!!!!!!!!!!!!!

Rich engine...

jbeech,
Yeah the cyclic was slow. Way to slow even for me. It acted like it was a FP heli! Though in forward flight it got better. One thing I'll need to watch for is the tail rotor. It was still plenty fast, (not blindingly fast) but enough to spin the heli around quickly. Once the head speed comes up to about 1850 or so the tail is going to be really fast! Next weekend we'll be leaning her out. I also bought some 25% nitro fuel today. That should help get it a little better on power even at a rich setting. Around the end of the month I'm going to get a set of CF's and let her sing. I flew the Hawk with the Toki 40 in it and let her sing (I put thrust bearings in the blade grips) and she was excellent on the head speed. I had her at (1850-1900), but the header tank came apart and I landed her after I saw what had happened. I wasn't going to take any chances with the Hawk and just packed her back up in the trailer. I then got out the Tiger and started her up and flew her for the rest of the time I was at the field. Oh, and I thought I'd let you know, I had no problems out of the 6mm hex start adapter. No problems whatsoever! I'm sold. Along with Charles from King RC I hope we can convert the other fliers in our club over to the Tiger.

doorman,
The engine is still set to factory settings. Mid point on the idle and 2 turns out on the main. It starts fine, but loads up on the throttle at about hovering pitch. I'd guess that's the reason the tail is wagging a little and letting the tail drift also. She's got a good four cycle burp yet.
