Hey guys blades were tracking right on!!! And no issues in flight. Was very happy with stability. Can't wait to get this bird outside and start flying her around.

Nice flying, Forrest...

that part where you and your friends get a mega dose of several dozen carcinogens simultaneously was just my favorite part.

Lung and metastatic carcinoma is not a pretty way to die.

Please, never do this again...(operating a turbine indoors...
what, if anything are you guys thinking?)
Then displaying that abandon on you tube... you will probably
achieve a little unintended Darwinian selection.

JCZ, you are not a beginner, you have to know better than this.

BTW, Steve is right on, that is not a normal start and run for a Jaka or
anything else...more than a hundred start/runs at Jet Power, and not one like that...

Check that noise!

Hey, speaking of sound - I'd investigate the cause of that rattling sound heard during startup and flight. I'd say a bearing is about to frag. Could be on the turbine shaft. FIX IT!

Aren't you a Debbie Downer. I sprinkle JetA on toast and I'm fine. I think.

The Jakadofsy has an internal gear box and the components are sized to compensate for expansion due to heat.

But the funky sound stayed through the entire run. Under load the components should be 'play-less' and be silent. No, there's something wrong. Bill, I have seen and heard your Huey, and other than the rattling tail drive problem you once had, your Jaka was very quiet mechanically. Something else is going on here.

One day I'm going to see what's inside one of these turbines and remove the mystery. I don't like mysteries...

Hey Jay,

I forgot that this was the Odyssey that was sitting in the garage while I was there. Good to finally see it flying. Expect a phone call...

There was a door behind us that was open, so that all fumes could escape.

Thanks everyone for your kind words. Hopefully Dr. Tim can chime in here about the engine noise. I asked dad if he thought is sounded funny. He said he didn't think so. But I too thought that the rattling.

There may be something there but my speaker cable is busted so I am using cheap headphones until I have time to fix it. I did have the same concern about the clanky startup noise when I first ran mine mounted to a large wooden board. I think this noise is muffled inside a fuselage. But I get that on startup and during cool down. I actually think it emanates from the output gear assembly and the delrin gear and goes away as it warms up. The backlash between these two gears is specified in the manual but I don't remember what it is.

Everyone has a opinion.
So I would like yours if you don't mind.
I was there, the exhaust couldn't hardly even be smelled, As there was a breeze flowing through the hanger. (are carcinogens scentless?)
Would this be worse than a kerosene heater in your home, or following a citi bus on diesel?

Guess im not educated enough on dangerous carcinogens to understand the difference. Personally I would think following that bus would be worse when it will bring tears to your eyes.

By the way JC nice flight, cant wait to see it outdoors in the open space so you can really test it out.

Yes, much worse if you have turbine oil burning in with the fuel.
Be extra careful flying turbines in doors. The slightest "whiff" of fumes means you have just had a dose of carcinogens.

Sure feel sorry then for all of the turbine modelers out there. Because there is no way you could ever start one and fly without smelling it at some point in time.

Well, i guess you could wear a scba and be safe though.

It seems perfectly obvious to me. Whenever you are testing a new turbine helicopter, always do it outside in the snow and gale force winds. It's much safer than doing it in a hanger with the doors open

Also, whenever you fly a turbine helicopter, do not breathe. You may die from bad stuff in the exhaust.

Remember guys, safety first

As far as the "FUNNY" noise ... if fine! This is the New PRO version with the new Gears .. a bit noisy but bullet proof!!
Also test flying in a 10,000 sq. foot Empty Hanger ... I only wish I had a building like that to test fly my helicopters!

Nice flight, thanks for posting. That rattling noise noise was bothersome but then I am not a turbine expert or even owner.

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

Thanks for the input on the Engine Noise. I was a little nervous about that. Although no flames is a good thing.
