600 Maiden Flight - At Last

[shaun.e]

After a real bad day on Friday I finally got out of the the office and went to fly the 450 - which developed a real head wobble - looks like the swash is worn - so Friday just got worse.

I had been waiting to fly the newly completed 600NSP for the first time - so after some encouragement from my flying buddy (Backrowslea - Mat) I bit the bullet and took the 600 to the flying field and away we went.

My smile was the biggest on the planet!

What a joy - solid as a rock and only a slight trim to the right was needed - straight out of the box as it were!

Only one glitch appeared, at about 50% throttle and approx 20ft up, the revs on the engine increased suddenly. This has been run-in on the bench and has had 4 tanks through it, mixture is set at 1.5 turns out - if anything running a little rich and well cool. Not sure if this was the governor kicking in, the setup is for the gov to be off in Normal, on in IU1/2. Anyway, landed and took off again - no problems.

Does anyone have any ideas?

Sounds alot like the gov.
Are you sure it was off?
Which gov are you using?

Adrian,
Many thanks - I just worked that one out! As you correctly diagnosed, the Align Gov was on all the time. A combination of throttle stick setting in the gov and settings in the TR conspired to confuse me! I went through the set-up procedure again and now the red LED is on until I select IU1 (Gov on) then it turns green - I hope this is correct?? Not yet tried with the engine running though.

Correct.
The red LED indicates that the gov is off whilst the green means its on.

Thanks again, just need to sort out what head speed and how to measure it. Sky Tach seems good but expensive.

Something I have a problem with not having a tach.
However if you set it using the suggested settings that cam with the gov then you shouldn't be far off.
Normally set mine around 2100 rpm.

Nice one, another nsp in the air where they belong.
For general sports flying 2100 is great, could prob knock it back a bit if you wanted, for 3d, prob nearer 2200 is better.

I knew you could fly it..... Just took a little persuasion!!

It looked great in the air and am looking forward to seeing that beast move around a bit more!!

When are the parts for your 450 due in?

Thanks Adrian,

The dilemma is that I am using a Futaba T7C with the stock Align G600 Gov - and there are no settings listed. Perhaps someone out has a similar setup and can provide some settings? I did have some guidance through the Helifreak forum which suggests that the Gov value in the TR should be 60% in IU1 and 70% in IU2. My gov is off (for now) in Normal with the intention of spooling up in normal and then selecting IU1 for general sports flying. What do you think?
