First Scale Build. 600A109

Hi All. Just attempted a very first 600 scale A109 build. I know there are many builds but this is my version to the best of my abilities. I will run this build as an entire page from my website as the build has been detail photo documented with over 200 step by step pics. The page runs its entirety in sections as follows:

Part: 1. Componants
Part: 2. Anchors and Base for the mechanics. Internal Fitting
Part: 3. Tail cone alignment, binding and adjustments
Part: 4. Navigation kit installation
Part: 5. Retract installation
Part: 6. Transfers
Part: 7. Custom painting blades
Part: 8. Electronics
Part: 9. Head Options
Part: 10. Testing

All sections above are now complete. Part :10 Testing will commence 4-6 weeks from 20 March, 2015 when I will be documenting videos.

Here is the direct link to my build page. www.masjorc.limewebs.com/build.html

Hope you have lots to say.

Hi Masjo.. Welcome onboard

It certainly is a very detailed build with all of your photo's, well done so far and thanks for sharing.

Are you going to use a four blade rotor head?

Yes I am going to be using a quad head. I am wanting something nice Full Scale. I'm still deciding. I may order a Flybarless Metal 3D Floating 4 Blades Rotor Head Set for 600 Helicopter RH250 for now. But still deciding. . . . . . Or just spend the $$$$ now and be done with it.

First choice
http://justscale.co.nz/catalog/produ...u6diond0rvh0n6
Just been emailed. . . . . . Australian based and out of stock. If I do get this later on I will have to change the blades as I think this head is rigid. More research to do I think?

Second choice
http://www.cnchelicopter.com/bell-42...rc-helicopter/

Third choice/temporary
http://www.ebay.com.au/itm/Flybarles...-/400691709686
Looks like this for now UNTILL I can get hold of what I'm really wanting.

The third one is a CopterX head. I had this on my A109 also from RCA and it didn't play well with my Heli-Command. The blade grips are floating and because of that most FBL systems don't work well with it. It was designed to work without a FBL but I never felt real comfortable flying without one, instead I went with a rigid head and the Heli-command.

It's not bad I just didn't feel comfortable without the FBL system.

I knew at least one pilot I had seen on the forums lived in Slidell. My route to the Cajun Heli Fest takes me right through it. Maybe you might be attending, too?

Oh yeah I will be there. I'm going to try to get there Wednesday afternoon or Thursday morning by the latest.

I met you and your wife at Dalton last year Don. I fly the 600 size AS350 that is black with a gray "SABERCATHD" on the side and the black 700 size MD500.

When will y'all be passing through Slidell?

Hey Andrew. I certainly remember the AS350, but don't ask me to remember names, lol. I really am bad at that. See you in a week and a half.

I have got an HK450V2 5 bladed rigid head with plastic flexi blades and flies awsome with an FBL. Great combo.

Ok now, having no experience with flapping heads . . . . . . . . I have been doing some research on 600 4 bladed flapping heads without e-stabs and came across this. . . .

" Howeveer I have a theory based on all this, and that is that a 4 blade head does NOT need electronics support because the blades are exactly 90 degrees apart, so you just need to set up the phasing mechanically in the usual way and then each blade automatically handles the dreaded precession that needs electronics if using a 3 or 5 or 6 blade head.

Make any sense ?

However, I suggest you try it out without electronics first, it REALLY DOES WORK."


Found this here:
http://www.electric-rc-helicopter.co...ads-t3999.html

So this would put this head in the perspective of a two bladed flybarred head? Interesting. . . . . . .so I am thinking I might run my flight tests (pod n boom) directly from the AR8000 and an Inertia860/9254. Sounds good is it not? My understanding of why these 4 bladed flapping heads work without e-stabs is explained in simple terms above.

Hmmmmmmm. The above makes sense to me so I'm going to go with this. The e-stab I have onboard I will disconnect (already programmed) but leave installed for now. Any suggestions would be appreciated.

What you say is very true, however mechanically setup phasing is never 100% right vs RPM's. you can see it in some of the older scale helicopters with 4 or 5 bladed rotor heads on YouTube(wobble/shuffle in flight). You may want to look into a Bavarian Demon or others, it will make sure your phasing stay's at 100% right all the time. With no need to install a follower arm if your head will support direct link hook up..

I have two big scale 4 bladed rotor head helicopters flying with the BD's. the real cool thing about that is you can fine tune to your liking.

But for sure you can get along without the FBL unit.

JLogan: Point taken. Scale with an unassisted 4 bladed flapping head is very new to me. All this information is very handy. I will know what I am faced with once I start flight testing. Thankyou

Oh. . . . .never heard of a Bavarian. Just googled it

Teaser pic

Hi guys. I couldn't resist the temptation to quickly reassemble my build and do a photo shoot. . . . . . . . well really to check the swash plate ring clearance. Testing will commence in a few weeks.
