Just avoid a particular corn field, and you will be ok! ;)


Sorry, the devil made me do it!

Hi rgreen24

Can you please load some pic's of your Integral?

thanks

Rgreen24
What part of the plane do you consider weak. I am expecting mine to ship today and hopefully will have it by the end of next week. Any info would sure be helpful.

Nevertheless funny. Rusty Dose told me that Home Depot will be delivering a load of plywood to the field to ensure that this baby stays nice and fresh.

Look forward to seeing your pics and thoughts on the airplane, Robert. Take care.

RE: Composite-ARF Integral, kinda build thread
 

Believe me guys I will not be visiting that corn field anytime soon:D

I will load some pics soon as I get a chance. Not sure if I should start another build thread or just keeping this one going.

Hi all
There is a new scheme for ZN Integral!

nice, is'nt it?

RE: Composite-ARF Integral, kinda build thread
 

Hi Guys,

Anyone know where order the integral from? (South Africa)
Sent mail to ZN Line and Composite ARF but still no reply (waiting for a week already)

Any help would be appreciated.

RE: Composite-ARF Integral, kinda build thread
 

Hi terrebse

Try send JP Zaradini (Z of ZN) the E-mail again, He will answer you for sure!
If not, you can always send a PM to him. His nick name in RCU is JPZ.

Good luck

Hi Guys

The new ZDZ 40 F3A has arrived and is in stock, pictures and details will follow later

RE: Composite-ARF Integral, kinda build thread
 

Hi Iain

What are price and delivery time of this engine ?
Thanks
Claude ?

RE: Composite-ARF Integral, kinda build thread
 

Since the first run of Integrals are at their new homes, mine included, there might be some questions needing answers since the instructions aren't ready yet. If so, please post them here. Tomorrow is a down day in MI at Andrew's house, and I'll go back through this thread and try and add some more details for the construction (and repost it from here out). if pics are needed, I'll have to get them taken when I return. Not sure when the instructions will be done, should be soon, and when the are, they'll be on the website.

RE: Composite-ARF Integral, kinda build thread
 

Mine arrives tomorrow. (I hope)
Is there anything with the plane that will give me an idea of where a good starting point is for the CG?

RE: Composite-ARF Integral, kinda build thread
 

There is nothing in the kits yet. With the YS (and OS) mine was nose heavy. If you are going glow, I would keep everything back. I had everything forward and have added 3ozs to the tail. I forgot where the CG is, so when I get back, I will post it.

Couple things off the top of my head:

If you are using a 2-stroke or 4-stroke with a long pipe, you will want to mount the pipe floor in first.

***Remember to scuff the inside of the fuselage where you are going to be gluing anything in. Use some 220 grit, but be careful not to over do it and sand through the inner layer of glass. Then clean it off with some rubbing alcohol on a paper towel.

Measure your rudder horn from the outer most holes and then use a servo arm that is the same measurement on the outer holes. This measurement is also going to be same coming up from the rear of the fuselage where you will drill holes for the cable exits (if running straight cables). If you cross them, not sure where they will be (back further though).

Horns: if you are using the stock horns, make sure the holes (for pushrod) in the horns are over the centers of the pivot points on the surfaces. For the rudder, the pivot point is where the pin is, not the LE of the rudder. This puts the horn mounted back in the rudder about 1"-1 1/2" deep from the LE. If you put the rudder LE down on a table, the horn doesn't extend past the LE. I will measure mine when I get back. The aileron and elevator horns are probably easier to align over the hinge point because you can sight down it easier.

Screws for stab mounting: There is no locator point on the surface of the stab, but if you look inside the stab root, you will see a “glob” of epoxy over the end of the tube area. This is where you want to drill the hole for the stab screw. I drilled a pilot hole first in the stab without the tube in. Then put the tube in a redrilled the pilot hole through the first part of the tube. Then removed the tube and again redrilled the stab with the correct size hole for the screw used (4-40) and drilled the stab tube out for the same. Sand down the little bulge in the tube after drilling into it so it slips in easily into the stab socket. I used a small piece of sandpaper rolled up to scuff the inside of the tube and a Q-tip with alcohol on it to clean it. Then use a scrap piece of ply with a blind nut and epoxy into the end of tube centering it in the hole you drilled. Make sure to use vaseline, chapstick or some kind of oil in the threads so you don’t glue them closed. When drilling the tube for the other side, make sure the stab is mounted on the first side and hold the second stab all the way on. Getting someone to help hold the stabs against the fuse makes it a bit easier.

Servo mounting is straight forward.

Chin: I used 4 bolts, but others may have a more favorite way.

Canopy: This might be a bit tricky. I used 2 pins in the rear, 2 hooks on the base and a 4-40 bolt in the front. It’s not coming off (yet at least). I did have to drill through the clear canopy for the bolt, so I tape over the bolt hole so air doesn’t get in there when I fly. I have flown one with a hatch latch in the rear and 2 hooks near the front, but it didn’t work because the fuse twisted the canopy off. I think because of the size of the canopy, it will need 4 support/pinned/hooked points. 2 in the rear (half way up is a great place) and 2 near the front. Depending on how you want to attach it (screws, latches…) can also determine if you use the hooks or not. I know this is a bit drawn out, but I don’t think there will be just one right way to mount the canopy. So if you have ideas, post them here and lets see if we can find a best way.

OK, time to go fix the foamies I broke last night then off to warm Champaign... I hear it's almost 25 there. It's only 20 here in MI.

Jason My integral arrived today. Mine did not have the firewall installed. I will be using a Hyde mount with the built in nose ring. What is the amount of right and down thrust I should introduce to the firewall.

Thanks
Carl

RE: Composite-ARF Integral, kinda build thread
 

set it to the nose of the fuselage

RE: Composite-ARF Integral, kinda build thread
 

Haha
I figured that much.
Seriously should I introduce any angle?

Carl

RE: Composite-ARF Integral, kinda build thread
 

Seriously, just match the nose

RE: Composite-ARF Integral, kinda build thread
 

Okay will do.
Thanks

Hi Jason,

I am putting together my Integral, I have a few questions below,

1). I asked you once before about adhesives. Just curious, how did you attach the clear
plastic part of the canopy to the red base and how is it holding up.

2). I was fitting the undercarriage last night I noticed when drilling the holes in the bottom of the
fuse that there appeared to be a space in the material between the inside of the fuse bottom and
the underside of the internal carbon undercarriage plate on the inside of the fuse.

When I started to tighten the bolts the landing gear was compressing the materials together
and I ended up with a ridge where the fuse sides meet between the undercarriage lags and
a split between the 2.

Has anyone else had this problem. I am thinking of marking around the U.C. legs and cutting
the fuse bottom out and epoxying liteply plates in to support the U.C. without putting all the
stress on the bottom of the fuse.

Anyone thoughts, Jason and others. I will try and post a picture later.

3). I was thinking of using ZN line horns, do you think that would be Ok. It seems as though
there are blocks under the control surfaces to take different types of horns as opposed to
just using the ones provided.

4). I noticed earlier in the build thread that there was a photo of the rudder pin partially
installed with a 90 degree bend at the bottom, presumably you cut out a slot in the bottom
of the rudder for this to sit in, and I guess that the tail wheel bracket stops it falling out. Did
you glue the pin in place or not to allow the rudder to be removable.


Just got my Plettenberg 30-10 Evo and Schulze 32.8KA ESC today. Progress is coming along
well and I have not spent too much time on it really. Will post some photos later.


Cheers,

Elmer.

Hey Jason, are you back home yet to give us the CG:D?

RE: Composite-ARF Integral, kinda build thread
 

R Green
Did I read correctly you ordered the Carbon Canopy?
Did you get it yet?
How much does it weigh?

Carl

RE: Composite-ARF Integral, kinda build thread
 

No I did not order the Carbon canopy I ordered the silver canopy. Have not received it yet but Jason hoped that it would ship this week from the factory.

RE: Composite-ARF Integral, kinda build thread
 

I just ordered the Carbon Fiber. I was told 10 Days till delivery.
I will let you know the weight when it arrives.

Carl
