Most of ANY of my vids show a pitch guage on the head setup vids...

It is so that the shaft moves freely through so the load is taken by the outer race, through the bearings to the inner race, which bear on where you want the loads transfered.

Remember that "we" (in Europe) are only at 2 o'clock PM, so we can keep on for many more hours.

PS: Thanks again for your swift replies

[Finless]

Well I just posted 2 more... SO THERE......

One more compressing... Electronics Install.... Should be up in about 30 minutes...

I am going to fly like CRAP later today

Bob

[Finless]

Electronics Placement is now up!

2 more vids on the buold and I am going flying..... Gotta wait till the wife is up though so it's going to be about 3 hours...

Bob

[alain_soresca]

Hi, Bob!

I have watched your excellent videos and have a couple of questions to the SolidG/S9257 setup.

If I heard and understood right, you would use 6.0V in your setup and therfore you added a step-down to 5.1V on the tail servo (9257). On the CY page, http://www.curtisyoungblood.com/faqs/search.php?id=2287, they have written that the SolidG need 5.7V regulated. Shouldn't we border about that?

And one more thing. My Futaba reseller told me that I can use 5.8V regulated on the S9257, since it is designed to be used will a fully charged 4.8v NiCd/NiMh battery. Any comment to this?

Well here is what I have to say to that

1) You didnt read Curtis Spec properly.... Read it again here is what it says
Solid G Max Voltage
The Solid G is rated up to 7V. This voltage limit is higher than any tail servo on the market. Most tail servos have a max limit of 5.7V (some as high as 6V)
For customers running voltages higher than 5.7V it is recommended you run a voltage

The gyro has no problem up to 7V!!! It the tail servo they are talking about at 5.7V.

2) OK now regarding voltage unregulated vs regulated. Here is a little audio segment I did a while back that talk about this:
http://video.helifreak.com/?subpath=...regulators.mp3

The Align BEC in this ESC is a switching reg not a linear reg like before. Regardless it puts out 5.9 when set to 6V.

Now regarding the specs on the 9257... Yes you might get by with that using them on the 5.9V BEC for cyclic but the duty put on the servo as a tail servo from a gyro is more stressful. I know some people are getting by running this servo on a Trex450 at 6V but I also know some that have burned them out. Myself I am not going to take that chance!

Hi, Bob!

Thank you for clearing this up for me!

I just read the info at the link I provided and thought that was for the gyro. My SolidG (and manual) is back at CY for "cleaning" and I hope I get it back to Norway before my 500 is finished.

I will have to created (or buy) a step down for the S9257 then.

Once again, thank you!!

Have a nice Christmas!

Morten

[Finless]

You too..... Happy Holidays and I hope your gyro gets home soon!

Bob

[Finless]

OK final build vids are done.... MAIDEN TIME

Bob

[hopntod]

thank you BOB!

[Street Flyer]

Thanks Bob. Can't wait to see some videos of this in the air.

[Antony Konnarides]

Bob,

You must have broke all records for heli build vids.
I just wanted to say THANKS for keeping it REAL.

Antony.

[Hangarace]

Bob Merry Christmas from us flyers up North. Thank you for the 500 build videos. You are what HeliFreak is all about.:Band:alcohol

[pistolero]

Thanks Bob

Have a great Christmas/Holiday

AND AN EVEN BETTER NEW YEAR

May all your landings be INTENTIONAL

[spencer737]

i will be runnign 9257's all around, so i will set the BEC for 5v, do i need anything for the tail servo (9257) like will the gyro step-up the voltage?

[gagi]

Great Job Bob!

You really nock these build videos out! No matter what your day job is you have a future in the RC heli buisness!

I can't wait to pick up my 500!
