    hi all!!

    How the giles is doing 3D with os160fx???

    harriers, hovers, waterfalls, flatspins etc'...

    what is the best cg for that?

    the lower price for this BiG machine sound a really good deal if that bird doing 3d/\.

    This plane is cheap because it is an early GP ARF design.. Will not 3D well due to the high wing loading.. It is capable of nice spins and IMAC type aerobatics.. If you slow it down though you may be in for a suprise..

    I haven't gotten into everything yet, but with my 0S160 fx on 10% nitro and an cheap master airscrew 18x8 prop I can hover and do several torque rolls about forty feet off the deck and even climb a bit. It hovers about 60-80 percent throttle. it'll even climb on you if you manage to keep it perfectly straight. I've been bringing it lower and lower to the ground. Power seems to be there to at least bail out horizontally as long as the nose stays higher than the tail. I want to try a 20x6 and see how she does. I am suprised to see her doing those things because I read a lot on these threads about her not being a good 3d candidate. Certainly, this plane likes to rock around and stall, but I think she's capable of more than just scale pattern stuff. My set ups are posted throughout this thread. I'm not sure where my cg is now. I know I need to move it more toward the tail. If I can get a digital video of the hover, I'll post it. Its certainly not easy to hover, (I don't know if thats cause I just need more real practice or what) and I don't have absolutely unlimited vertical, but I can fly straight up from take off several hundred feet. I'm really enjoying it. Saturday was the first day I really really tried to concentrate on a hover and by Sunday I was holding the hover for up to ten to twenty seconds in a good wind. I even got some Kudos from our veteran pilots (Horray for Real Flight G2! It may not be totally realistic, but learning the hand eye cordination for hover and 3d was good enough for me to be able to do it at the feild). I'm sure the Giles is not a strong 3d performer, Harriers might be suicidal. Its not a kyosho flip or a U can do so you can't fling it around and bail out. You have to be methodical and practice up high a lot. But I think with practice, and if the plane lasts long enough for you to get confident with it, its A LOT OF FUN and can do some impressive careful 3d!! You won't be disappointed with the 1.60. As its broken in its gotten more a more power. (Even with a slim line pitts, mine is loud as heck though)
    There is a video somewhere on RCU of a guy doing some cool flat spins and some other stuff. Check around page 6 or so.?

    Ok. This past weekend I used 15% nitro and a 18x6 Wide (3d) APC prop. It was so cold my fingers were numb and dumb but I did see a difference. Its turning up around 9300 rpm static. The local hobby store doesn't stock 20x6's so I will have to wait and order one.

    I took my first flight with my Giles 11 23 2003. Flew it again today. The OS 160 pumped Runs GREAT. I'm surprized I still have this plane! The Fusalge Really wants to break in half. The cracks in the monocoat are plane savers. Hard landings or snap rolls seem to be the culprit. I keep glueing it back together it keeps flying. Never finished th Katana I bought way back when. I was going to put the power from this in it! So I bought a Super tiger 2300 for it. Now I'm looking at the New Wild Hare 73" Edge. When I get it I wil retire this well amortized bird that has given me great service! If you follow these threads and beef it up where it needs it it will give it a long and happy life. I'll chime in again when it's done but it's looking good so far! Probaly jinks it now ;<{ )

    Hey spyder0069 Congrats. You read the book on this one! The key is keep the weight down. I was flying mine today. A friend at our field had a brison 3.2 in his! It didn't last very long! Another guy had the same set up his survived. but he pulled the engine and sold the plane. I've got the Engine in a Wild Hare Edge 540T 84" It's got plenty of power for it! Wonder what it was doing in thsi plane! How is that 2300 working out for the long haul I just bought one for a GSP Katana 72"

    As for the talk of a such a small powerplant for a large plane I think most of you are nuts or live at sea level .On my 1/4 sc. giles I have a O.S. BGX 3500 swinging a BME 20x10.Unlimited vertical, great knife edge, all around 3-D machine .But here's a problem , my density altitude is always around 8K up to 10K so a big engine is needed for the performance I want .Also since this is a known plane for snapping 2 feet off the ground before the flare (I know because I had a small prop breaking incidence )I added stall fences to prevent snapping problems and add to a useable flare approach .This also slows the plane down about 10 miles an hour less for a very comfortable landing similar to most 60 size planes .Flying weight is 14 lbs. even with awing loading of 33.14 oz. per sq. ft.Fuel is home brew 7.5 %

    Well, I finally got the guts to get Rachael out and maiden flight her this weekend. What a great 5 minutes, probably the best 5 minutes I have had in the 3 years that I have been back in the hobby. But, first a little background on my progress since 2002 to build the suspense.
    Most of the information on my set-up starts on page 10 of this thread. I did get my CG back to 9.5” by adding ‘Rachael’ as a pilot sitting near the back of the cockpit. I also had to add 2 oz. of lead to the left wing tip for balance. I have gone through 9 planes getting my skills up to where I thought I could handle something this big. All of them are or were 40 sized from a Kadet to a 4 star. 4 of them are still flying, and 5 of them are toast including a coroplast, but each one of the 5 that I lost taught me a valuable lesson, like ‘don’t listen to your flying buddy when he tells you “Go inverted! You’re ready!!!”, you’re pushing the sticks and you’re ready when you know you’re ready!! Antenna OUT!!!! Don’t fly when the engine really isn’t runnin’ right, it doesn’t get better in the air. And several more that don’t need mentioned. It seems that just about the time I would think I was ready to get the Giles out, I would burn one in for some reason or other and my confidence would fly out the window. I have only burned through about 4 gallons of fuel in the past 2 years, most of the time I get a couple good days in per month so I really haven’t got that much stick time, but I do have Real Flight G2 with Add-on 3 and my Giles 202 in it, which has gotten a lot of stick time.

    Ok, so much for background Saturday was a beautiful morning, just a whisper of a breaze, clear and warm, we fly at the Alpine City Airport off of a taxi way. A few guys flew and I flew a ramrod a couple of flights to get my thumbs relaxed. Most of the guys there left early, but 2 stayed around to confirm that I actually got a flight in, if I got back on the ground clean. Hee Hee. I put the Giles(Rachael) together and the excitement started. My knees were a little week when the Moki 180 fired up, deep and solid, a whole lot different than the 45’s and even the 60 4 stroke I have. Taxied out and made the turn down the runway, then let her sit there idling for a few seconds while I stretched and built up my nerve. Throttled up smooth and easy, the tail raised in less than 10’ straight down the middle with just a little right rudder. At less than 50’ I started feeding in a little elevator and she broke smoothly from the ground. Now my knee knocking has extended to my shoulders. A little right aileron and banked smoothly around 180, still climbing to about 100’. I made a couple of circuits and found that one click of left trim on the ailerons made her fly straight and true at about ¾ throttle. When I started thinking of doing a couple of maneuvers the shakes increased through my arms all the way to my thumbs. ¼ up elevator and I was into a smooth climb making a nice 50’ loop. Adrenaline started pumping and on my next pass I tried a roll, ½ right aileron a little too much down stick inverted so I made a big hump in the middle, but that wasn’t too bad. A couple split S’s and immelmans and I was ready to get her down. One low and slow(1/2 throttle at about 20’) circuit to see if I could line up with the runway then on the second base leg, I throttled back to ¼ and she settled, 2’ high over the threshold, throttle back to idle, a little up elevator and she settled softly to the tarmac about 10’ after passing my position. Taxied back to the pit and my timer went off, 5 minutes from pit to pit. I was elated, I have not had more fun with any of my other planes in a single flight. My 4 star can go over 20 minutes per flight. I sat down, had a smoke and calmed down slightly, the shakes took awhile to clear but I felt great. WHAT A PLANE ! ! ! ! !

    Post flight- I gave one of my 'witnesses' my camera to catch a few pictures. (No Joy. All the care and attention I give to my planes' batteries and I didn't check the camera's they were dead, what a fool!) I used about ½ of my fuel so an 8 minute flight will be about right in the future, but this might get a little longer when I get the Moki broke in and lean her out a little. A recharge of the battery showed that I used 145 mhr. So a full flight would be pushing 300 and a second flight would require a little field charging to be safe since I’m using a stock 600 mhr pack. I will be getting a higher mhr pack as soon as I can. I’m just a fun flier, but with a plane this solid there is a lot more fun in the flying.

    I Have a friend at our field. That has the 2300 in it it performs as well as mine with the OS 160. I bought a 2300 for my GSP Katana because of that. Plus the new 2300 from the Orient are supposed to RUN GREAT!

    do you think the 3250 giant scale will be to much, or wont fit in the cowl? i want some power but ive heard the OS does great in it so if the 2300 does as well then i think im sold.

    It should fit, assuming you mount it sideways. The cowl is quite wide.

    The Giles tends to build tail-heavy, so the extra weight of the 3250 may help you out in the balancing department.

    My (former) (crashed) Giles has been resurrected by one of my clubmates... it soldiers on with a sturdy Moki 2.1 on the nose.

    rod2_hi - "deep and solid" is an excellent description of the Moki's exhaust note!

    On another note. I *strongly* recommend you swap out that 600 mAh pack. This is a big plane, with multiple servos at the end of long leads... You'll find that a 10-minute flight will pull more than 300 mAh from the pack. Not to mention that the voltage and available amperage out of nicads decreases as the pack depletes - you'll notice that the bird will 'feel' soft in the air, or may be prone to glitching on maneuvers which cause the servos to draw lots of current (snaprolls, knife-edge flight,etc.)

    Nicads are affected by cold weather as well. Lower temps slow the chemical reaction within the cells, which reduced the amount of amperage they are able to supply.

    Couple a (relatively) low-capacity battery with a (fairly) high load... add cold weather... and what if a cell in the pack causes your charger to false-peak?

    Change out that battery. I wouldn't use anything less than 1200 - 1400 mAh.
