Default 1/4 scale Giles 202

I have been flying 40 size stuff up to now, so this is new to me... Just brought it home earlier tonight, and need to set my TX up for it. Im told that it will be easier to fly than the small one's im used to, but was wondering if there's anything I should be ready for that might catch me by surprize. Im told that if I set the rates low to start off, I will be amazed at how nice and easy it flies compared to my 40 size fleet. Does that sound about right ? It sure is a big sleek puppy, and it has a Super Tiger 3500 under the canopy with a pitts style muffler. Everything is new, and it has only been flown 3 times, and he said that it was all checked and rechecked, and it was good to go. Im going to check everything before I even start it anyway so I am familiar with it. Will this big Giles 202 do anything I may not be ready for, or will it just amazed me how well it flies ?

G'day Mate,
I have a 27% Giles 202, & you Will be amazed how easy it is to fly, just make sure it is not nose heavy, or tail heavy for that matter, fly it & don't be afraid to adjust your balance point, nose heavy, they can be a dog, but move it back & find the sweet spot & WOW, just sooooo easy.
It should fly inverted, needing only a very small amount of down elevator, like 1/8" stick movement, when you find that spot, Knfe edge figure 8 circuits, are a breeze, & heaps more of course.

Thanks ! Im taking it out to the site here in a bit for my first flight with it. My friend Greg who is use to these things is going to help me out. He said the same thing basically. These big one's kinda intimidate me a little, but that will probably change today, I hope... lol

Well, we took it to the field, but couldn't get it started. lol Brought it home and found the problem. We were not priming it enough. I got the program now ! Runs like a top ! I pulled the cowling and tightened everything up, and did the same to the whole aircraft, checked everything again. She ready for take off if the weather is ok tomorrow. If not, no biggy, I know it's going to fly great !!! My electric starter wont crank it over, but it starts with one flip of the prop after priming...

G'day Mate,
Are you sure it's a ST3500, if so ST recommend a 18x8 to 20x8 for the ST3250, I think you will find that a ST 2300 run in prop is an 18x8, & a 16x8 to an 18x10, for flying, so maybe you need a slightly bigger prop than the 16x8 for your ST3500.

Dennis,
Like Allan said, you should be under propped. I used a 16x8 on my Midwest 72"Giles with a Moki 1.2 That made an excellent combo and with the gear height, an 18" might be the max dia. I have a 96" Edge with a ST 3250 and a 20x 6/10 prop, which I found to be the best for pulling power. For that 3500, take along an 18"er to see if it doesn't pull better.
My 3250 takes about 6 priming flips or a couple of fuel squirts down the carb and I can start it on the first clockwise finger flip on the spinner.

I finally figured that priming thing out... My friend who I got this from, said he's flown it 3 times, and it pulls real hard straight up. It may not be a 3500 then. Too bad, I had the cowling off earlier, but I didn't think of looking. Where is it marked on these ?

To start this one, I open the throttle all the way, and crank it CCW by hand, till I see fuel in the carb throat, then reduce throttle to fast idle, attach glow starter, and flip it, but sometimes it starts in the wrong direction. I opened it up a few times today, and it didn't seem underproped to me. It didn't see to rev excessivly. He also said the engine was new, but that they didn't make them anymore. Does that help ?
Also, I was going to run the 20/20 I have, but it sounds like I should be using the 15% that I have. Is that right ?

I've only run mine on 15/16 fuel
The actual size is stamped in small numbers on the outside face of the mounting flange. The 2000 or 3000 on the side of cylinder case is just a general sizing whether it be 2000,2300 or 2500 etc.
Your friend is correct, the 3750 has replaced the 3000 and 3250.

Forgot to mention, an OS 'F' plug helps too.

I've been lookin at my servo's and looking them up, and reading the tech notes on them. The elevators have Futaba 3010's, and tech note don't say much about them. Just nylon gears and they can draw 2 amps each.

For the alerons, it has 2 Futaba TS64's, and tech notes state that their for .20 to .60 size planes ! Now thats scarey ! Isn't it ?

Then on the rudder, they have a Futaba TS 70, and tech notes state their for giant scale planes, I feel good about those...

My thoughts are to get 4 more TS 70's and replace the 3010's and the TS64's. What do you guys think. As I said, this big stuff is all new to me. I just know what I read...

I can't afford the new digi's, but I put 70 to 100 oz. metal gear servos on my 27 to 33% planes.
I'm not familiar with the newer #'s you mentioned.

Well, this is a giant scale, and the TS 64's are for .20 to .60 size, are 69.4 oz @ 4.8 volts, and their on the alerons. That can't be real safe... and the elevator servo's (s3010's) have nylon gears, and just state standard high torque. Im gunna do some upgrading... The rudder servo (TS70) is 106.7 oz, super torque, metal gear, ball bearing, and only $34.99 each. And they say their for giant scale planes ! This is a no brainer...

It may be an 18x6 now that I think of it. Rats, I gotta check again. I'll look for the numbers on the engine flange too. When ya get older, ya need to start writting stuff down, or everything in my case.

Just pulled the cowling. The prop is a 16x8, and the only markings I can find on the engine is the number (20) stamped in a round area on the left side, and Super Tigre Made in Italy on the right side. What size engine is this ? There doesn't appear to be any markings on the mounting flanges. The right side is difficult to see with the muffler in place, but that area looks blank to me...

Looks like you have the 2000 or 2500 which would equate to 20cc or 25cc. It's not the new 2300 since the seller said it was no longer made.

Well, im not so sure now, he was sayin the 3500 was not made any more, but it's not a 3500.
We have the book and the origional box for the engine comin now, and that will help. I can't get it to idle slow like it should. It gets down to 3000 ok, but lower than that, say 2600 or less, and it quits, like it loaded up, but I have to prime it to start it again, so it's not loading up. I've tried richening it up and leaning it down, it just won't idle slow. I have the high speed set fine though. Right now, the high speed needle is set at 41/2 turns out, and I have no idea what the low speed is set at. The guy that owned this plane origionally died, then I got it from a guy that bought it to help the son out. I got it for $495.00 with a tx, so I couldn't pass it up. Now if I could just get it to idle correctly, I'll be in tall cotton...

Well, I found out that it's a G2300 finally. I set the needles according to the manual I found on Tower Hobbies. Hopefully I'll have better luck now... HSN was 4 1/2, and is now 3 turns out, per the manual. LSN was set with the barrel open about 1/32". Blew in the fuel inlet, and opened the LSN until I heard air, +1/2 turn more. I got my fingers crossed.

G'day Mate,
You'll need to do more than cross your fingers, with that motor.
Best of luck, & watch out for rich midrange.

Yeah, i've been reading about that. I'll post my results tomorrow if the weather clears up, and I just heard that it will in the afternoon. I believe that my HSN was way to rich (by over a turn), and my LSN was way to lean trying to compensate for it. I don't think I had any fuel coming thru the idle circut at all. It wouldn't idle below 3000 rpm, and I had to prime it every time to get it started, and have the idle trim way up. Again, sounds like no fuel thru the idle circut due to lean LSN. I gotta think positive and logically here. From what i've read, if the midrange is too rich, the idle is also too rich. Thats straight from Supertigre if im not mistaken. I've been doing an awful lot of reading on this the last 2 days. Wish me luck, I want this thing to idle like my Saito 56. lol

G'day Mate,
It may idle like a Saito, but wait until you try to open the throttle.
Be aware the manual can't help with actual running of the motor, that has to be done, by ear, & by testing.
Best of luck, you'll need it!

If what you say is true, I'll be the first one to admitt it, and after all the reading i've been doing, im fully prepared for the task at hand. I might add, I do 90% of my flying around half throttle or less, so a midrange that is too rich is out of the question for me. I also demand a very slow and steady idle... I'll post my findings later today. Dennis
