I need to order this week some stuff for the Gilis.


Are 36'' servos entension enough or 48'' for the elevator servos? What about ailerons extensions lenght?

Yes 36" are fine for the elevators.

You know I sell extensions, yours will be packed up tomorrow.

I'm setting the receiver at the aft edge of the internal rudder servo tray. Using that location a 24" and a 36" extension brings both aileron leads to where they need to go with a bit to spare. 36" from the elevators and rudder, if aft mounted, is comfortable to the same location.

Pat and others:

I am now assembling one of the fast-build production Giles as a check to make sure everything is OK and just because I like the Giles so I want one. It's certainly a nice thing to be able to indulge myself this way, this job has certain benefits.

Even though I prefer the DA-85 I'm going to use a DA-100 on this one because I have one that is paid for. Not everything is free, even for me. And because I am hoping to get enough time this year to make it to one or two IMAC contests and a little more weight helps in flying precision.

This fast build stuff is sure nice not having to hinge or mount the canopy. The factory did a better job with the canopy than I would have ever done, and the hinging job is very clean.

As a practical matter our planes were always very close to the "quick-build" that another vendor pushes, it was mostly just the hinging that was needed.

I'm on here because I am genuinely excited about this plane. It looks so good, is so easy to put together, and flies so nice I am just really tickled about it. And the yellow/blue is absolutely beautiful.

I'm quite jealous. No hinging and canopy fitting makes everything too fast and easy. I just completed the canopy installation this morning and have the rudder left to complete one side to wind up the hinging. I'm still waiting for a wrinkle to appear. This is the first arf ever that has not developed a wrinkle in the covering.

The parts fit so far has been excellent. The largest issue I've had has been in deciding where to put things. So much room provides for a lot of options. You just have to settle on one and run with it.

I can see where the 85 would have an advantage in the weight department. Twins will start out a little nose heavy but will be simple to correct for. Tail mounting the rudder servo(s) is a great start, and not locating the batteries until last should take care of any differences left.

Speaking of canopies, I went with 10-32 nylon screws for the hatch again. In removing the blind nuts that are installed in the hatch tabs I found that applying some heat to the back side of the blind nut permits easy removal without damaging the ply that they are mounted. Tap the remaining hole 10-32 and apply some thin ca to harden the threads and you're gtg. I tried going with an 8-32 but the threads would have been a fraction too loose.

I'm going to use the supplied 6-32 screws just to see if they will stay in. I've had better luck with this lately, we'll see.

Yours is an excellent idea.

BTW our 40% helmet head pilot sits down between the canopy rails as nice as can be, just secure it with some silicine glue and it's done.

You dog!! I flew Altavillan's Yak ( and RTK's Sukhoi) yesterday and I have to admit it looked a lot better with a pilot in the canopy. Mighty nice of them to let someone fly their planes that hasn't done R/C is 6 months. I don't know if I would have the same amount of trust and confidence.

Do you have any W/H graphics laying around? It would look soooo much better if the Giles went out to a few fields and people could see where it came from on first glance.

Pat,
I seem to remember somewhere in the recesses of my mind that you haul your planes in a 8ft bed pickup. If this is indeed correct, will the Giles fit (diagonally corner to corner) with the elavators and spinner on and still be able to close the tail gate.
This was a big selling point (to me) for the 35%.
Thanks in advance ( I think)

It sohould fit straight ahead, it will stand on its nose in my garage with about an inch to spare, plus you can remove the spinner and cock the rudder all teh way to one side, that will save another 5-6 inches.

Turning it crossways corner-to-corner may actually take up more room because you are trying to shove the elevators into the corner.

Pat, I'll send out some graphics. I did not realize that I did not request anything on the plane, things were a bit rushed at the time.

I understand.

Sailing,

I had the plane in the pick up the other night without horizontal stabs or a spinner and it fit fine. I'll have to get back to you with the assembled fit. The elevators sit more forward that they did on the 35% so turning the rudder helps. With the spinner I intend to use the finished plane length should be about 97", so a straight front to back fit might be a bit snug.

Worst case scenario would have you removing a spinner or the stabs but the servos are in the stabs making that procedure easy. As soon as I have her done I'll take a picture of the fit in the pick up. I agree that how it transports makes for big impacts in buying decisions. It's one of the reasons that I've remained at 35%, but a larger scale Giles keeps things in the size ballpark. 2,010 square inches of wing area helped move me to this one as well.

OK, I finally have the full assembly completed and all the good stuf inside is in. I'll do some pictures of the pick up bed fit and some linkage installations tomorrow.

In the mean time I suppose I can relate some of the assembly process and a couple of extremely minor fit issues I had with this one. The wing tube and tube sockets were a bit tight for the main wing. This required that I wrap a 3/4" dowel with seme 80 grit sandpaper and pass it throught the wing and fuselage sockets a few times using trial and error fitting until the carbon tube slid through without much resistance. Total time: about 15-20 minutes. The aft wing locator dowels were a bit snug on the aft side of the holes so a quick pass with a round file straightened them out. Total time: 5 minutes. That pretty much covers all the fit issues. Pretty much a bunch of nothin' when it comes to fit problems

Those of you that intend to tail mount a rudder servo or two should make a note of this part. The elevators of a Giles do not have as much of an angular cut on the inside end as Extras, Yaks, and Edges. Due to this the linkage rod from the rudder servo to the elevators could easily end up in a bind with the elevators if you have the rudder horn screw too long or the clevis connection too far out on the screw shaft. If the rudder horn screw is left too long it will hang up on an elevator. It's easy to avoid.

All you need to do is set up the rudder linkage at no more than 1-9/16" out from the center of the rudder hinge point. Cut the screw shaft off short enough that it won't make contact at various deflections. The closest the linkage rod will come to the inside of the elevator sweep will be at neutral so if you miss there you will miss everywhere. If you set the rudder linkage up at 1-1/8 from the hinge line and 1-1/8" at the servo horn you will be guaranteed a minimum of 45 degrees of rudder travel, and probably more depending on how you have your transmitter travel adjust set up.

Using the same linkage mounting dimensions on the elevators will yield between 50 and 55 degrees of elevator travel at max deflections. You definately are not limited on surface travels with this plane.

As has been already noted, ball links should be installed at the inner side of the servo arms at the ailerons and elevators. If you install them on the outer side of the arms they will most definately bind on the servo arm at max deflection angles, limiting travels and inducing high current draws. No biggie but I thought I would save you some set up time by catching this in advance.

Depending on where you install the receiver, the longest servo extension you will need for the plane is 36". I installed my receiver where you would normally install the rudder servos for a pull-pull installation. Using that location, for a two servo aileron installation it takes a 24 and a 36" extension for each wing. For a tail mounted rudder installation it will take a 36" extension for each servo. For the elevators you might get by with 24" extensions but 36" assures there will be no problems.

Where you install the throttle servo and the ignition battery will determine what you need for extension lengths there. Using the stock ignition switch position (forward on the fuselage side) and installing the ignition battery on the deck directly aft of the cannister tunnel required a 6" extension for the ignition switch. Not the best idea, hard wiring would be better but what the heck. I installed the throttle servo to the right and just forward of the gas tank, requiring about 18" of servo extension to make the receiver.

All the basic hardware that arrives with the plane fit just fine and are appropriate for the locations. You won't need anything extra in that department. Note that the basic hardware does not include stuff like axles, dura collars, gas tanks, fuel line, fuel dots, wheels, fuel tees, clevises and horns, and things of that nature. Tom's accessory hardware pack will save a lot of time and gas money if you get it all when you order the plane. I prefer his new line of ball link hardware to anything else that's available. Since I used a tail mounted rudder servo there was no concern about rudder horn offsets so a 10-32 ball link and horn screw is perfect in that application. If you went with a dual rudder servo installation the same parts would work perfectly on the other side. You don't need pro Links if you obtain his hardware pack. The tubes and rods included are plenty stong for the job.

I don't have a clue where the plane is supposed to balance yet but I'll see where it came out naturally tomorrow and go from there. Dial in the surface travels and fine tune the wiring installation and she should be ready for weight checks and flying on Wednesday. I didn't do anything special to save weight so this could be viewed as an average installation using a 100cc twin up front. At the moment it has a single 5,200 mAh Lithion battery for the receiver but there is a mounting provision for a second if I need weight or more juice. I doubt I'll need more juice.

Still no wrinkles

Pat you are an evil man! It was about at this point last year in your Sukhoi build thread that I got hooked. Still have the Sukhoi and still love it.

Maybe you won't like the way this one flys. If you do like it you may have to help me hide it from my wife.

Pat:

A few of the things you wrote may be confusing to some who have not worked with this plane, I will attempt to clarify. I am assembling one of these also and I took a different approach on a few things, I plan to do my own build thread here too.

I think here Pat is trying to say that the pushrod for the rudder, if you use a rear mounted rudder servo instead of a pull-pull, will interfere with the inner edge of the elevator if the rudder horn stud is longer then 1 9/16".

"Inner" meaning the side closer to the elevator. On mine I just put a couple 4-40 washers between the ball link and the servo arm to avoid this problem and still mounted it on the more convenient outer side. I will go back and re-check this to be sure.

I was flying mine balanced at the front edge of the wing tip. At that CG it fles almost neutral, with just a whisper of down stick required to hold level when inverted.

More to come from me.

I found in my build the same things Pat described. The ball link needs to be mounted on the bottom side of the servo arm, on the fuselage side, or the elevator on full deflection down will hit the connecting rod from servo to tail hard point. This is not a problem if using pull pull rudder set-up.

Flew mine last weekend with the CG right on the wing tube, inverted 45 upline straight as an arrow, no nose droop and no climb. Easy to check balance at this location by using string wrapped around wingtube, slide wings on and pick model up.
