Carl Goldberg EAGLE 2
 

Howdy all, has been along time since building anything RC. I was once a avid RC boat builder/racer. I also got bit for awhile by the RC Buggy bug and raced that circuit f/a time. Have been away for along time and recently decided to try my hand @ a Aircraft. Now I have built many scale balsa models for Free Flight and have a general knowledge of working with different types of woods, but this will be my 1st RC Airplane. I chose for this project what I hope is a solid design for a 1st timer.

Kit picked for this project: Carl Goldberg Eagle 2.
engine: Super Tiger GS40
radio: Futaba 4YF-FM 4 Channel

This was picked out by the wonderful owner of my LHS. He was most helpful and steered me to where a beginner needs to start from. Yes I said the beginner word @55.
So with all that said and after reading thru about every build thread here, please any and all feel free to help in anyway you see fit. I truly mean that! I have set up a build area in the garage and the tail feathers have been started. I am sooooo glad this is a laser cut kit. I have discovered from other laser cut kits to lightly sand away the ash from the laser cut, I am using SIG-Bond and CA. Oh, total so for in the kit/eng/radio: $340.00, I thought that was pretty good.

He sure did not do you any favors, if he steered you to an FM radio, when 2.4 ghz are about the same price.

http://www.rcuniverse.com/forum/js/f...what_smile.gifWell, I did say I was a beginner and must admit, I left the choosing of equipment up to him. I do ask to please pardon my lack of knowledge and or stupidity. I am one of those rare people who believe when asked, a person will help and or be honest, until proven other wise. Thanks for your input, I now will seek more info into radios!!!!!!!!!http://www.rcuniverse.com/forum/js/f...n/drowning.gif
Is there a radio you can recommend. I paid $130.00 f/this one. Or will this one work for a trainer/beginner?

RE: Carl Goldberg EAGLE 2
 

FM will work great for your aircraft. 2.4 has some great benefits in that interference is nearly a thing of the past, but they are much less forgiving of poor Rx battery management. The only real drawback of FM is the fact that you need to stay aware of frequency use. That is to say you can't just turn the radio on if there are others flying until you know for sure no one is flying on your frequency. There are also rare cases in which you have dead zones for specific frequencies. They are generally small and don't cause any real problems (the majority of FM radio "problems" occur in the link between the brain and fingers or thumbs.)

Great airplane and an easy build. Enjoy!

Also, give this article a look:

Don't worry for a second about your FM radio. I'm about the only guy in our club that flies with an FM. I think the FM has big advantages over the 2.4s. I don't worry about anybody shooting me down, cause I'm the only FM flying. If my radio goes bad, I've got a bunch of guys fighting to sell me their old FMs( at some REAL bargin prices) There has been at least 1/2 dozen planes lost in the last 2 or 3 yrs due to " voltage problems" attributed to the 2.4s. My old "junker" FM, not lost a one due to voltage issues. Right now I know of 7 or 8 six or 7 channel FMs that can be bought for $50 or less. That's not counting all the recievers I can buy for 5 bucks !!! I have 7 planes in my hanger, figure it out. Each plane would take a new "2.4" receiver @ what, a 100 bucks each or go to my buddies & buy the FMs all day long for 5 or 10 bucks. It seems to me the guy at the LHS did you a BIG favor !!!

RE: Carl Goldberg EAGLE 2
 

Don't worry about the radio, FM still works fine. As far as the plane, The Eagle is a good trainer that is easy to build and will serve you well. Sometime, it will biuld so quickly that you might think you need to slow down. But it builds up nicely. There are a couple of threads here about the Eagle, both building it and modifing it, and many of us that are quick to answer any question you have.

Here are a couple pics from last year when I re-covered mine, (originally built in 1997)

RE: Carl Goldberg EAGLE 2
 

I like FM radios and the Eaglet is not a bad trainer. There are better ones. Usually, bigger is better. Try to keep it as light as possible. Have fun!

RE: Carl Goldberg EAGLE 2
 

You've got a good radio and trainer. If you can find someone to show you how to cover and buddy box for you - you'll be in tall clover. Have fun.

RE: Carl Goldberg EAGLE 2
 

Your FM radio will serve you well with the Eagle. Solid, easy to fly plane with a solid, easy to use radio - hard combo to beat! The only real reason I went with a 2.4 system is that I want to be able to fly multiple models with one radio. The model setup functions and easy binding of the radio I chose make it easy. Well, that, and it was actually cheaper than getting my 20 year-old AM and FM radios back into working order.

RE: Carl Goldberg EAGLE 2
 

I have a couple of recommendations about building the wings on the Eagle II. It's a wonderful plane, but it has way more dihedral then necessary. Do NOT build the "A" wing. Ground handling with any crosswind at all is atrocious. I don't even really recommend the "B" wing, as it is still too much dihedral, but you can get by with it. If you have the skill, you should cut the dihedral of the "B" wing approximately in half. They also recommend joining the wing halves with CA glue. I recommend you use epoxy to join the LE, TE and spars and to attach the wing joiners, which you will need to make if you decide to reduce the dihedral.

RE: Carl Goldberg EAGLE 2
 

Gosh, where do I begin? For starters thanks for all the encouragement about the radio, I was bummed out all day over what I thought had been a poor purchase. I did look @ several trainers and choose this one. I was impressed by what others had said about it on this very Forum and my LHS had in stock, of which I might add, he had very few kits @ all. I am a builder and I know a ARF will be in the future, right now I want to build what I am flying, too ole school I guess! As f/the FM Radio, that was the type equipment I was use to using, tells you how long it has been since I purchased one. Another thing I liked about this Radio, you got 4 servos, receiver, re-chargeable battery and other bits and pieces, the other Radios priced much higher did not even come w/servos? You bought them sep, but I guess this is to buy them to suit your application. So again, thanks to all who offered your kind words about this purchase. I do have a question: the system comes w/4 S-3004 servos, and I am plaining on building the flaps in the wing, so all four will be used. Will these have enough torque to move the large tail feathers and or flaps. I am sure there is more than enough for the throttle.

Now as for the wing, I am looking @ the A wing, the owner of my LHS suggested this one for the benefit of the flaps and that the wing is almost built flat. But I am more than open for suggestions. I had thought about purchasing the material to build a 2nd wing w/o flaps and building w/a little dihedral to start the flight training with, then switch to the one w/flaps. LHS suggested just going w/the A wing and not plug the servo up to keep them in neutral until I am ready to fly w/them. Now as far as joining the two wing half's, the instructions suggest thick CA, then using thin CA to attach the provided web material. Again, I understand keeping her light, but I do agree w/epoxy for this critical assembly. I also will use SIG lite span w/epoxy mixed w/alcohol applied to the middle of the wing after joining the two.

The mfg suggest you use thick CA, epoxy and thin CA f/assembly. I will use the recommended glues, but I like to use SIG-BOND for the most part during assembly. I apply to both surfaces, allow to tack up, apply another coat, join the two and wipe the over flow off w/a damp rag. Of course this is done after sanding away the ash/burn from laser cutting.
As you can tell from my Forum tag, Duco is also another fav of mine, but afraid might not hold up to the loads required of the other glues.

It has been some time since I was worked up about a project and this has all 8 firing!!!!!!!!!!!!!http://www.rcuniverse.com/forum/js/f.../msn/49_49.gif<br type="_moz" />

RE: Carl Goldberg EAGLE 2
 

OK, build the B wing, reduce the dihedral in 1/2, do you suggest flaps w/this method as well? Thanks for you helphttp://www.rcuniverse.com/forum/js/f.../thumbs_up.gif.

RE: Carl Goldberg EAGLE 2
 

Read it, great stuff there and I am thankful it is apart of the Forum. Thanks for your helphttp://www.rcuniverse.com/forum/js/f...wink_smile.gif.

RE: Carl Goldberg EAGLE 2
 

I think you mean "ailerons", Not "flaps", ailerons move opposite directions giving you the roll for turning, flaps move down together giving more lift and drag for slower landings (not needed on this plane). The ailerons are definitely the way to go, and build the wing that gives you the least amount of dihedral (upward angle of the wing like a V) if you have some help with the learning process. If you are going to try this alone build the other wing as it will be far more stable. The reason for not building it this way if you have help is you will have a plane that will be much more enjoyable after you learn to fly well, and your instructor can keep you out of trouble until then.

RE: Carl Goldberg EAGLE 2
 

My first build 25 years ago was a Carl Goldberg Eagle 63 (now known as the Eagle II).... I still fly 2 of them. You made a most excellent choice.... despite flying many planes since then... it is still my favorite. It is durable..... easy to rebuild (and yes you will "ding" it from time to time) and a wonderful flying machine with forgiving characteristics for the first time flyer..... you have done well "grasshopper"

RE: Carl Goldberg EAGLE 2
 

Flaps are certainly not needed. Do them only if you want to play.

RE: Carl Goldberg EAGLE 2
 

As far the servos that come with that radio, they will be fine for the the Eagle. I use S148's in mine which are less powerful and lack the ball bearing that the 3004's have. The 3004 is a good general use servo.

In case you are not used to using CA adhesives, you will want good ventilation!! Particularly when you are glassing the wing joint. CA gives some wicked fumes that many of us have trouble with.

Keep asking questions and enjoy.

RE: Carl Goldberg EAGLE 2
 

When I first started with planes was when I was about 10, with sticks and tissue paper kits (none of them ever flew).
Then when I gave up motorcycle racing in 1995, my father-in-law was into RC planes. But he did not convert me; I did that on my own.
At that same time, my niece gave me a couple of RC books, as a gift. She did not have a clue about RC planes, but one of the books turned out to be a real treasure trove of information (when you consider I was starting from ground zero concerning RC). I did know I wanted to build because I knew I would probably need to repair sometime in the near future. And if you have built, then you would have a better chance of knowing what is needed to repair and how. The author of this one book built 10 trainers, with tips on how to improve them. This book can be purchased thru Amazon ("Building Your First Radio Control Airplane" (RC Performance Series, No. 6) (Paperback) by John Carroll) for about $3.50 (used).
I keep this book in my reference library and refer back to it from time to time. It helped me a great deal when I first started with RC planes. Maybe it could help you. Most of the RCU members here are a good source of info, also.
I have probably told you more than what you really wanted to know, but I thought a little background might help.
Good Luck in this great hobby.

RE: Carl Goldberg EAGLE 2
 

The reduction of dihedral idea is a good one. One thing that can be done to lighten it up, make it fly 'cleaner' and be a little more forgiving with 'abrupt arrivals' is to make it a taildragger. Just depends upon how comfortable you are making modifications to the kit. If you get the main gear axles fwd in line with the LE of the wing that would be about right. The tailwheel can be mounted to the rudder (I think- it's been a while since viewing the kit) or another method can be configured.

RE: Carl Goldberg EAGLE 2
 

Holy Cow Batman, came home from work, fired up the PC, went to my now fav Forum and was so excited to see all the responses I received today full of most helpful advice.http://www.rcuniverse.com/forum/js/f...ey/msn/lol.gif

cfircav8r: My bad, aileron, aileron, aileronhttp://www.rcuniverse.com/forum/js/f...ssed_smile.gif

Chuck54sd: thank you Chuck-saun, I had researched and thought this was a good 1st kit and a great platform to learn to fly from.http://www.rcuniverse.com/forum/js/f...wink_smile.gif

JNorton: I hear ya, Bro............http://www.rcuniverse.com/forum/js/f...sn/thumbup.gif

crossman: thanks, I was so hoping they were ok, learned from RC Car days, anything w/ball bearings is goooood.........http://www.rcuniverse.com/forum/js/f...sn/devious.gif

Hogrider: like your handle, when I was a wee lad, I grew up on a farm and we had this sow as big as a couch, no joke, when my buds would walk up the dirt road to my house, I would come from around the barn ridin her, they would fall down laughing until I started chasing after them on this mammoth. And that was way before anyone coined the phrase, rid'in a Hog.
But I do know what you mean. Oh, to finish the story, she went feral and my Dad had to put her down after killing and eating a calf. True story!!!!!!!! http://www.rcuniverse.com/forum/js/f.../msn/tired.gifPS: sad day f/me too, I had raised her from a small piglet. I know many will laugh when they read this, but it has been proven, a pig is smarter than any dog.
Will look for the books Bro, thanks.

ARUP: I had a build article for the Eagle 2 storied on the computer and just what you suggested is what the guy did, but he started w/front wheel as designed, but added blind nuts to the rear to mount a tail wheel for when ready to use that type set-up. Thanks for the tip friend.http://www.rcuniverse.com/forum/js/f...ades_smile.gif<br type="_moz" />

RE: Carl Goldberg EAGLE 2
 

Eagle 63 was my first RC aircraft as well. Had many great flights with it over the years. Started life with a K&B .45 Sportster in the nos but eventually mounted my Fox .50 an modified it to take a bigger tank. Flew the heck out of it until I clipped a barbed wire fence on a landing approach and decidedto retire it.

RE: Carl Goldberg EAGLE 2
 

OUCHhttp://www.rcuniverse.com/forum/js/f...what_smile.gifI try not to think about stuff like wire fences! Thanks for the in-put. Glad to know she served you well.

RE: Carl Goldberg EAGLE 2
 

I have not posted any photos yet, don't want to bore w/the basics, will have something to show soon.http://www.rcuniverse.com/forum/js/f...eeth_smile.gif

RE: Carl Goldberg EAGLE 2
 

Hi Duco,
The basics is just what a new pilot needs and you are in a prime position to help them.
You may have a technique or method that an old dog could use also.
There are new people out here that may be thinking of a trainer to get started flying and they could use your help.
Don't underestimate your impact on a new modeler or old one.
