Audacity Models Pantera 50 - Tiger 50 > First Flight.... and a question....

Well, I got the Tiger flying on this very cold day! It seems very stable and I am very excited. However, I noticed that it takes alot of throttle trim to keep the engine running (but it is to the point where the clutch almost and sometimes does engage). If I lower the trim, the engine will die. I am sure I have one of the needle valves wrong - I am just using the factory settings. Oh, BTW I have a OS .50 Hyper engine. Any suggestions?

Hello, Peter. What's happening? We need to talk about your TPS reports

My first thought is you are running a little rich. What fuel are you using? What does your exhaust smoke look like?

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

Fuel

fuel is 15% nitro heli fuel. smoke is there but not overwhelming... would too rich of a setting on the high speed needle affect the idle?

Yes it will. Also, 15% is fine. There is no need to spend the money on 30% when you don't need it.

The high speed needle is like an "overall" setting as well as top end. Once you get the engine boken in, you sometimes have to richen one needle and lean the other to get the motor running just right. Turn the high speed needle in a click or two and see if you can tell the difference. I know that some manufacturers say to use the low speed for anything on the low side, but I find that sometimes you have to tweak the high just a little, and then fine tune with the low side. Since you are still breaking in, make small adjustments and keep it slobbering rich (if your're running a ringed engine).

Idle Settings

With the new engine, you will be running a little on the rich side on both the high and low.... I would leave the high alone for "now" and just bring the low end in a little to get the engine to run a little cleaner for break in... later as you move into forward with it you can change your high end as needed and then if need be you can change the low end again...
Not too sure how the Hyper will react on the 15% either... I have only ever used 30% in mine...just read the info with the engine to comfirm that... but shuttle is most likely right that 15% should be OK for the break in period....
Good Luck and glad to hear that you have it up and running...

New motor should be run rich i think for at least the first gallon of fuel probaly try 1 1/2 turn out from the fully closed position and if u have acess to a temp gauge try not to run over 200 degres f. Tom

Sounds like a lot of good advise here. Personally I run 30% in my own helis now. I've used 20% before but seem to get a little "edge" with the 30. From what you said I'm with leaning the low speed needle just a little, try it and see if it's better or worse. Also try changing the glow before you go changing a lot of carb settings, ya never know. I've spent a lot of time trying to get an engine running good only to find the plug was "weak". Good luck with it, and let me know if you need anything else.

I'll admit I'm not a great pilot, but I can hover with the best of them.

FWIW, the OS Hyper doesn't have a "low speed needle"

Hyper has one needle to adjust.

Check your linkage to see if it it open enough at idle, I do believe you trim all the way down first for throttle, not at half. So check that and see where you are.

Tomorrow I hope to have mine flying.

everything seems OK. I have checked it a hundred times, and had someone else look at the beast.

Hyper Low End Adjust....

Well you guys made me go look..... and you are correct in the fact that there is only one NEEDLE to adjust, BUT the small black screw with the cam plate on it is your low end adjustment....so even though it doesn't look like a needle... it is a low end adjustment.. clockwise will lean and counter clockwise will richen...

Thanks, Stan

Still having the same problem - I leaned out the needle a couple of clicks, but the engine dies if the throttle trim is not high enough to keep the engine running at a speed that engages the clutch at times. Obviously, this is not good.

Perhaps its a bad plug - I will put in a new one and see if that does the trick.

I had three flights today (after getting 6 more inches of snow), and I need to adjust the blade tracking a bit...

Is it possible that you have a tight clutch liner?
I had one recently on a JR 30, just held the head, slipped the clutch a little and it was fine after that.
Just a thought

what do you mean, 'slipped the clutch'?

Gave it a little throttle without letting the head spin, causes the clutch to slip.

I did that a bit, but I then thought I smelled burning clutch so I am not sure I should be doing that... I just ordered a bunch of new plugs so hopefully that will remedy the situation.

Did You Lean the Low End??

Did you lean the low end so that you could run it at idle a little slower???
I have also done the hold the head trick to some in the past, but it does make you nervous when you smell the clutch liner smoking!!!
Just turn the clutch bell by hand and see if you feel any drag in it and if so remove the engine and sand the liner down where the high spot is...
Also what plug are you running... I seem to have the best luck in all of my engines with Enya #3.....

Good Luck... Stan

Just burp the throttle a cpl of times to seat things, if you are smelling burnt liner, than you have another issue and don't continue.
