Started gluing the chicken together. No instructions were included, which is no big deal really, but it would be nice to know the CG location.

G'day,

As this morning seemed to be perfect ( lots of sunshine and no wind) for an EEP Eagle maiden flight, I proceeded to the garage/workshop to position the battery for COG, but got real surprised to find in addition to the 5 .25oz battery I needed to add another 9oz's to achieve COG. I'm fairly confident I did not get over zealous with glue on the tail section and normally the addition to weight to the nose is not all that unusual in RC models, but this sure "feels" heavy.

I would appreciate input from other Eagle fliers as to added weight to achieve COG.

Thx

Bob

I did not add any extra weight. I used a 3s 1300mah pack. Had to move possition it as far foward as it could go.

I use a Thunder Power 2100 3-cell with it pushed far forward to achieve the center of gravity. The pack weighs about 5 1/2 oz so putting in 9 oz. of weight in the nose seems excessive. The balance point with the wing on is 6cm back from the front opening in the fuselage. Mine had two indention's in the EPP to show where the CG was however, I doubt that the newer models have this. Double check your balance point prior to doing a maiden otherwise she may be nose heavy big time. Good luck on your first flight, I hope it's a non-event!

Shouldn't these birds follow convention of 1/3 MAC for COG? "One third mean average chicken (wing)"

I admire your artistic talent and you sure are a great artist.

We used a 3s 2000mah(5.29oz),did not add anything.
Flying weight about 500g~570g(17.6oz~20oz)

G'day,

I really appreciate the replies. After all is said and done and the dust settled, the problem ends up to be me. I was sure I read about the COG in this thread and was very sure the number 6 was used. The error is, it's 6cm as FLYPARTY shows in his post, not 6mm as I was using.

Of course I removed the tail assy and any excess glue I could find, before I checked RCGroups for replies. So since that's not the problem it will get reattached as quickly as possible as I sill have sunshine and no wind.

FLYPARTY, thank you for the COG info and the artistic comment. In my opinion it came out OK, but does not compare to most of the others shown in this thread.

Cheers

Bob

Here she is

AUW 470 grams ~ 16.6 oz
Park 370 1080 kv motor swinging a 8x6
TP Prolite 1320
Added .15 oz in paint total.
She looks good from afar, but far from good. Will look great in the air.
Thanks for the incredibly descriptive tutorial Maybz. I had held off for over a month because I was afraid I could not get the same results. I am thrilled with how it looks. The wing tip section on the top got a little messed up but other than that I think she looks great.

Great looking job.

The other birds will think it's their cousin.

Very nice work Jon, you will have alot of fun with that.
Haha, that Swallow that E-Aero is marketing is obviously "inspired" by the Dreamworks Alula. I have had an Alula for a couple of years. After awhile its nose got a bit mushed up so I cut it off and put a small outrunner on it. Goes like a rocket with unlimited vertical and is still a good ridge soarer. Now I have some EPP painting skills I will have to go over it again and give it some better plumage.

Hey Pitviper, you turn up everywhere!!
I usually use a 1000mah 3 cell lipo that hitches a ride on the Alulas sholder area. Just held on with Velcro so I can adjust the CG for different flying conditions. I also use a 650 mah battery for indoor flying which is alot of fun.
