The entire flying wire assembly is tensioned using the two lower cables that span from the inner gear to the fuselage bottom.

Assuming you have set up your flying wires per the instruction manual, the aircraft is disassembled simply by loosening the two cable bolts at the fuselage bottom. Then, all WING flying wire attachment nuts and bolts are removed. Assembly is the opposite: After attaching all wing flying wires, the entire assembly is tensioned by tightening the two cable mounting bolts - these cables never need to be removed nor are the wing flying wires ever unbolted from the fuselage or outer gear mounting points.

IF properly set up, tightening the two bottom cable mounting bolts until they are firmly seated against the fuselage will result in ALL flying wires being extremely taught!

Thanks Richard, that's exactly what I've been doing so that's a relief!

Do you find it's a sturggle to get the pin and circlip in place on the bottom wire when the assembly is under tension? I was thinking of introducing a turnbuckle in that wire assembly so I can tighten the wires up after the pin and circlip have been attached.

Thoughts?<br type="_moz" />

Once the cable pins and E clips are installed, you should never have to remove them for routine flying, transport and maintenance. You leave the cables loosely bolted to the fuselage bottom and the pin and E clips always remain in place at the inner gear mounting holes.

Only out of the ordinary service would require pin and E clip removal - I do not even find that I need to remove the clevises, pins and E clips for wheel pant removal... you can simply unbolt the cables from the fuselage bottom then pivot the cables through the wheel pant holes.

Not sure why you are having to remove the pins and clips?

OK thanks, that's set it straight for me. Leave the pin assembly in place and tighted the bolt into the fuse to bring them up to tension.

thanks

With the silver solder...what are you guys using. I have soldered before but I am only use to the solder that you get from places like (autozon,walmart, lowes, etc). What would be a great brand to buy for strength and reliability. Thanks!

The engine test was successful today http://www.rcuniverse.com/forum/js/f...sn/thumbup.gif

Now it&acute;s time to check the CG, on Saturday I will fly this beast again.

This time I will fly with a dummy radial, a new engine and a toher CG - I hope it will work**

I noticed a lot of you balance the Gee Bee right side up. From my experience I have always balanced my low and mid wing plane upside down. Which way is better to balance, and what CG machine do you have there.

Man I must of had invisible type on :)... I notice that most of you all balance the plane right side up. I have always balanced my low/mid wing planes & biplanes upside down. Is there an advantage/disadvantage to doing it right side up?

RE: Composite-Arf 33% Gee Bee R2 - First Flight - Pics - Videos - L@@K
 
I do not have an aeronautical engineering reason... BUT using logic, I would assume that any airplane designed to fly upright, would be better balanced, upright.

Yes, the Gee Bee racer is capable of aerobatics, but it was designed to fly around pylons upright and banked. To my way of thinking, this would require that the plane balance in the attitude in which it is designed to operate.

Perhaps an Extra or Yak or Edge would be better balanced inverted?

I have always balanced my aircraft upright. The aerobatic aircraft I have owned (Extra, Giles, Yaks and Laser) have all been shown in their manuals as balanced upright. When the CG is right, the planes fly right.

Maybe upright or inverted doesn't matter??[X(]

It depends on where your Center of Mass is... if it is above the wing, balance the airplane upside down. If it is below the wing (as it usually is on a high winged airplane) then balance rightside up. You just don't want to create a teeter-totter.

Just my $.02

Ok thanks for the feedback, I balanced my great planes gee bee upside down and all my other low wings. I was just curious so when I do get the CARF Gee Bee I do whatever I can to make it fly as smooth as possible!!! Thanks again

RE: Composite-Arf 33% Gee Bee R2 - First Flight - Pics - Videos - L@@K
 
Making the CARF Gee Bee fly as smooth as possible is easy... just make sure it is perfectly balanced, dihedral is equal on both sides, the engine runs flawlessly, and the person between the sticks is as "centered" as a Ninja:)

Great Pictures.....that model needs a pilot ;-)

congrats hannes!!

but now i am confused. earlier in the thread it was decided that a dummy engine disrupted the airflow over the tail which made it unmanageable...?????? or was it something else?
lets sort this out because i would like to put a dummy engine in mine.
the other question i have is does it need the baffles to cool the engine?

Yeah i saw that in a post a while back about the dummy radial....I just found another video of I think to be a CARF Gee Bee. Take off was pretty bad and the landing was just as bad, but it look to be in good shape to fly again.

I like to watch ANY Gee Bee R2 in flight, but this is definitely NOT a CARF...

Wing and stab are too long compared to fuselage, rudder shape, wheel pants and cowl are all different than CARF; red scallop paint is wrong as well.

Markings are also wrong, but this has nothing to do with CARF.

The plane seems a bit underpowered. However, fun to watch anyway:D

Congrats Hannes! Looks like you did a great job. Can you post some specs on your CG and dihedral? How did it feel in flight?

Thank you**

How does it feel? The Gee Bee flys very sensitiv and it rolls very good, the rudder is very importand and sensitiv.

I flow the Gee Bee with different CG&acute;s, I think every pilot have to choose the good one for his flight preferences.

Here is a video from my flight.

The DA 150 is brand new and do not run very good in flight. I have to change the intake of the air to the carburetor than it will work 100%.

The video is not very good, but perhaps some guys are interested to see this.

It was the first time that I flow with a dummy radial and there had been NO bad handling characteristics.

Here is the youtube link:

ED,
It's my understanding that it is the un cowled engine that interupts the airflow over the fuse that renders the rudder ineffective. It happens this way at least in models, of the the Gee Bee.
