RE: CMP 120 Zero ARF Build thread
 

Zero 332, I used the air retracts because that is what I had. But if I ever purchase any more retracts, they will be electrics. I have a set of the old Lados on a VQ P-40 and they work fine. For a 90-120 size plane, which are the best, the ones from E-Flite or the new lados from Magnum RC?

RE: CMP 120 Zero ARF Build thread
 

Thanks, glad you like it and no problem on the PM, I figured something was up. I'm not sure what is in your cockpit kit, but even drawings that came with the kit would help. So I appreciate any help you can give me.

I was thinking about drawing up a simple plan for the tail wheel, most don't like my drawings because they can be crude I guess, but I'm an artist! I don't need perfect lines, that's evil to me! lol! Post some pictures of what you are doing so I can keep track, it might inspire me!

Bean
i also have an older set of lado Im running on my zero never even so much as a negative hicup from them i just ordered the newer set from magnum so expect the same preformance, best thing to cone out since slice bread! Lol

RE: CMP 120 Zero ARF Build thread
 

Experten109/40 - Thanks for the input...but which item are you refering to as the "horn shaped valve"?...I'm not sure which is which.

dionysusbacchus - Wow, the tailwheel turned out fantastic...I'm a little too far along on mine to steal your design...but wish I had!

RE: CMP 120 Zero ARF Build thread
 

Thanks! Well it's no problem, use the design whenever you want, here is something for you to work with (some plans!)

I'm posting these for those that want to start a tail wheel of their own, it does not cover every single detail, but if you have some ingenuity it should be no problem. I will follow this with a complete build on the tail wheel for those that need more detailed instructions, I'll probably start this tomorrow. I have a few of these to build for friends, so it's not a problem, I'll just take pictures as I go this time.

RE: CMP 120 Zero ARF Build thread
 

Wish you have posted it few weeks ago, but thank you for sharing it.

RE: CMP 120 Zero ARF Build thread
 

You're welcome, maybe you can use it sometime down the road.

I just noticed that I left a part out, the top of the wheel yoke, I'll update the plan tomorrow.

*Edit 5/19/11* Retract plan updated.

RE: CMP 120 Zero ARF Build thread
 

Luke - Any progress on pulling new canopies?...I'm at the point where I need to either use the kit original, make my own plug....or hopefully con you out of one.;) My primary dsilike about the kit's canopy is the terrible clarity and they are brittle...if it's a polycarbonate, it's a cheap asia version.

RE: CMP 120 Zero ARF Build thread
 

mikes zero

RE: CMP 120 Zero ARF Build thread
 

That is a typical problem that a lot Asian built ARFs suffer from. They are usually thick enough but they are just made from some kind of cheap material.

RE: CMP 120 Zero ARF Build thread
 

There is lots to not like about the original kit supplied canopy! I got side tracked by the tail wheel project, but I have been working on the plug for the scale canopy. If you can wait just a little bit more, like through this weekend then I should have them ready. I have to fill the plaster in order to pull clear canopies, so it's matter of the filler drying mainly. I'll keep you all posted on my progress. So yes, if you can wait you can get one from me. :D

RE: CMP 120 Zero ARF Build thread
 

I cut my cowl flaps out also, nice exhaust! I will not be doing that, but it will probably look really cool when the engine is running.

What cowl is Mike using, it looks better than mine!

RE: CMP 120 Zero ARF Build thread
 

Luke - I'm not in that big of a hurry....probably a couple-three weeks away...just name your price and/or number of limbs...:)

RE: CMP 120 Zero ARF Build thread
 

Im using a cowl for a yellow zero however i have had to cut it up and re assemble it to get the correct diameter and shape, reason for the metal cowl flaps is that it allows me to hinge and get the clearances needed on the off chance that the exhaust should touch it would touch metal and not burn fiberglass cowl

RE: CMP 120 Zero ARF Build thread
 

Nice looking cowl flaps Mike. Are they going to be movable for better air circulation?

RE: CMP 120 Zero ARF Build thread
 

I will be able to position them where ever i like but they would be held stationary at a pre determined location

RE: CMP 120 Zero ARF Build thread
 

That is also good. It is better to open them then to cut underside of cowl for cooling

As my Zero is nearing completion, I have decided to paint inside of cowl(was white),
and I thought it would look nice if it is repainted.
Since I already have a green color that I used earlier to paint the interior,
I painted it.

Of course, the first step is protecting the outside

and then painting

and the result

And now the problems begun. When I was painting the wing I forgot the red lines on the top wing. S
o far I've used for all painting Kenda Kolor Spray Paint and was satisfied.
The color is dense and beautiful was sprayed, nice cover, does not leak ...

But let's go from the beginning. First, I stuck a narrow strip where the line will be around it and then stuck the protective tape.

When the yellow tape has been removed, I have to paint red colour.

Since I was lazy to go in town that day, I asked my buddy's wife to bring me from work
(she is working the paint shop) one bottle of red Kenda color spray. He later turn in, bring
spray but some Greek COSMOS. He says he did not have one I have ordered but that this one is better quality and of course
expensive. I believed him, of course (because he does wholesale colors in the same company) and as soon as first part of paint
was on wing, I know what awaits me. The color is just dripping with wings. it seemed a red water rather than ink.
But there was no return. Of course, I could paint this part f wing first in white just in case, but ...
I had to cross three times to cover the green below and while I have all the good protection
This "water color" was leaked under the tape.

Horror. Is not a problem as the color leaked, especially in this part, and a little scratching and a little
sanding will resolve the matter, also there has to be weathering too but gets on my nerves
simply that I was lazy and I did not went and bought what I think is good. If I has gone to store
I certainly would not buy the spray but would go in another store bought one that I know is good.

Well what is done is done. There is saying, that the best way to learn, is on your own mistakes.

RE: CMP 120 Zero ARF Build thread
 

Well, live and learn. Still looking awsome though!

RE: CMP 120 Zero ARF Build thread
 

lol! yea right! Not to worry, I can finance! ha! Seriously I have made some great progress and the canopy will be ready to go shortly.



No one asked if my tail wheel had a lock when extended, I can tell no one is paying attention to this, but maybe someone will use the info. Dave Platt had his Zero's tail sitting on the ground when the air pressure bled off, but not mine! I simply moved the locking mechanism under the cockpit. I was moving the elevator servo anyway because I'm trying to get as deep a cockpit as I can, so it worked out great for the scale retractable tail wheel.


The pictures are pretty self explanatory, and it works great, without air in the cylinder the tail wheel stays extended and I can move the plane around without it collapsing.

RE: CMP 120 Zero ARF Build thread
 

Did not think that it would not get it up and down, but I am interested how you are planing to do steering. And of course watch up weight
Mine will probably be heavier than I thought.
.

RE: CMP 120 Zero ARF Build thread
 

Platt used an air cylinder hooked directly to the lever on the tail wheel, it works but there is no down lock, if the air pressure gets low the tail wheel would start to retract with any pressure on it. I'm using fishing leader for steering set up in the standard way using a PC board pivot arm of course.

You put a lot of detail into your plane, I did not see your exact glassing method, but with a light weight method you can save much weight! I could definitely build a lighter fuselage, but I want to use this one so we shall see what the weight is. My tail wheel is just under 1oz in weight, not sure what the plastic robart one is or some of the other methods used in this thread, but it is as light as I can possibly make it.

RE: CMP 120 Zero ARF Build thread
 

dionysusbacchus what thickness is the pc board?

RE: CMP 120 Zero ARF Build thread
 

.062 Will you be building one? I have assembly instructions with pictures but I figured I'd wait until someone asks before I bother posting them. I added the lever also to the new plans, may post those later.

RE: CMP 120 Zero ARF Build thread
 

I for one would love to see your pictures and instructions for building the tailwheel!!!http://www.rcuniverse.com/forum/js/f...eeth_smile.gif I've got the 80" version working its way up the building list and am gathering all the info I can find before starting...

RE: CMP 120 Zero ARF Build thread
 

Really? You have to ask to if we want you to post them? :D
