From the front with headers - securing the cannister independently has allowed the use of flex tubing (not shown). I cut the headers short and used about 8" of flexible tubing. I believe this contributes to longer term maintenance free installation.

Dave, great pictuers. I heard some rumors about getting together next Saturday at one of the local fields in the area.

The rear-mounting on the cannisters is a wonderful idea. Any sense of the weight/sound of the JMPs as compared to the PEFA?

Don

Thanks for those pictures Dave, you've answered a bunch of questions I had !

Don- sounds great about flying on Saturday- keep me in the loop and I'll try to make it out.

Regarding sound, the JMB's have been very quiet. Keep in mind, however, that these are just mufflers and are not supposed to provide any boost in power. I have a Menz 32-10 on it right now and I get a great deal of noise from the prop (tached at 5600-5700). I am contemplating going to a different prop to get the sound down- hopefully a 2 blade like an MSC 31-12. Haven't tried a 3 blade yet.

Regarding the tabs on the end of the pipe- I'm a bit surprise that other mfgr's haven't caught on to this yet. If one were included, a tab could be welded on.

Talk to you later

Hello all,

I finally got around to have enough money for a DA100, and a new JR10X to put in mine 2.6m. I'm expect to have the radio, and engine mounted ready for next week end.

As far as setup, what do you guys out there have for CG - measuring from the leading edge at the wing tip?

As far as control throw, is the recommended setting good for first flight?

As far as weight: Could you list some of your weight here for the 2.6 with a brief description of what are in your installation?

Here is what I have and hope to stay below 25lbs. because I live at 5000' altitude.

da100 + standard muffler
32 oz tank
Ti. axles
Light weight wheels
Carbon spinner
LiIon batteries: 4400 on Rx, and 2200 on Ignition
No pilot, no cocpit
Aluminum bolts whereever possible

Lemme know what you think?

I balance mine by lifting on the wing spar inside the plane. My current balance point is about 1/2" behind the spar and it seems to be a good compromise between 3D and IMAC flying.

ok well i am not quite sure that i am gonna buy the 2.3 meter anymore. I just have the itch to get the 2.6 meter extra. My only question on this is about the material the composite-arfs are made of. I woulde really like to know more about it. I guess my problem is that i dont want to put a lot of money into the plane and have the material break down in like 7 years. Also i am sure it is strong but how would this material hold up after a couple years of 3d and pattern flying. I just want to understand this material a little more before i spend the big money to get it. Any help on this would be greatly appreciated.

The material, or contruction method used on the CARF is that of:

1. Layer of clear gelcoat, or white, or red or blue...depend on your selection. Also on prepainted version, paint would be airbrushed after the clear.

2. At least one layer of glass fiber, looks like 2oz.

3. One layer of high density foam - about 3mm - looks like Rohacell - but probably not because Rohacell would be too expensive.

4. Follow the foam is another layer of glass fiber.

5. Some carbon fiber on top of the glass in area where extra strenght, and rigidity is needed.

This method of constuction is very similar to full scale aerospace construction - very light, and very strong. This type of constuction yeild strenght in the direction needed. Also curves, and corner also provide stiffness to the whole design...hence less formers are needed to be installed.

I could go on and on here...but basically I feel that the constuction method is excellent. As thin as the walls are...they surprisingly has great resistent to punture. Pretty easy to fix if one has any experience with composite constuction.

I don't know...my 2.6m is probably by far the best airplane I've ever bought. Straight and True right out of the box.

Not a bad value at all for a $990 (Red/White)

Darn...I should be the sale guy for CompARF...

Ryan

Don! If using one 8611 per wing on the 2.6m CA Extra, would you make a new servo mount in between the existing mounts to drive the aileron from the center, or is the aileron stiff enough to be driven from the inner existing mount?. I am not into 3D, only IMAC Intermediate Class flying.

Thanks,

Art Fressola

Art, I burned out an 8411 and flew my 2.6M for a day with just the inboard 8411 working. The ailerons are quite stiff and I don't think you'd need to make a new servo hatch.

If I were choosing between inboard and outboard servo bay, I'd use the inboard bay.

2.3m to 2.6m- why not a 3m? Picture to motivate... (it fits in a Taurus wagon even with the 3 blade prop on)

Dave, I'm running an AM 28x12- have not tried a quiet 2 blade yet, but like the faster speed of the 3 blade. It seems to work better with this design (a clean one).

Best of luck,
Don

Here is pic of my new 330L Extra 2.6M. I'm still in the process of dialing it in and breaking in my new DA-100. I have had a few problems with the plane but I "think" I have most of the bugs worked out. Which everone you choose, I'm sure you will be very pleased. They are great planes. Ricky

The extra 2 grand to set it up comes to mind [:-]

Good point- its all relative, I suppose. A good setup at half the airframe cost- you've got an excellent combo.

Things have changed a lot with these high tech planes. The 3m CA's are less now than the 2.6m FC just two years ago, and the CA 3m is almost $2K less than what I paid for (FC). Not much motivation to sell mine due to this, but I'm having fun in the interim.

Anyhow, here's an interesting combo- DA 100 (or Equiv) on the 40% with the same # of 8611 servos as one would put 8411s on the 2.6m (two each aileron, one each elev, two rudder) weighing in at under 30Lbs. Very light wing loading and quite the show for 3D.

I understand someone in the area is quite successfully running a BME 102 on the 3m Extra.

Cheers,
Don

Hey guys,

I think the BME 102 Don is speaking about is actually a BME 110 X-treme!
It is in a 3 meter Composite-ARF Extra and is owned by Kris Welter ?
The plane weighed 28.5-29 lbs I think.

I know because I had the chance to fly it a couple of weeks ago after an IMAC contest in Mocksville, NC.

This plane and engine combo is AWESOME!!!
It would go vertial for takeoff for ever.
It could be hovered easily with PLENTY of pullout power.


I have a 3 meter Fiberclasisc's Extra with a DA-150 and a Mejlik 32X10 prop.
We did a vertical drag race from takeoff and I got off the ground just before he did and he STILL BEAT ME!

My buddy also had a Composite-ARF 3 meter Extra with a 3W TOC 150 and Mejlik 32X10 prop.
They did the same drag race and it was VERY close.
