CompARF 2.3 or 2.6
 

HI Guys,
I'm trying to decide between a 2.3 Extra or a 2.6 extra.. I'm wondering if the DA50 w/ tuned pipe is enough for the 2.3? The CompARF website says that DA should be coming out with a DA75..has anyone heard much about that motor? I figure that the electronics for both airplanes will be fairly identical , so it just works out to engine..DA50 vs. DA100 and a bit of a difference in airframe price. I'd sorta like to have a smoke system as well and the DA50/tuned pipe, wont really allow that.
Thanks..

Get the 2.6 with the DA 100.
You can't go wrong with that combination

RE: CompARF 2.3 or 2.6
 

If the price is not an issue, get the 2.6 with the DA100. Else you may consider the Composite-ARF Extra2x2 with the DA50. Or just wait for the DA75 for the 2.3....

If you ask me, out of the names you mentioned, DA and Comp ARF, I dont think you could go wrong with any of them. Heck I bet you could put a DA-50 in a 2.6 and it would have the powre to fly. I have seen the 2.3 and DA-50 w/ pipe combo. I has plenty of power, but you want to keep it as light as possible to maximize the thrust:weight. That probably means no smoke or any other fancy stuff. Now the power isnt just incredibly awesome, but it is unlimited. Now the DA 100 on nearly anything has superb performance. If you ask my opinion, the bigger one is the way to go. Now I have also seen a DR hobbies 2.6 Extra with a 3W 75. It is basically the same as the Comp ARF except it has a aluminum wing tube instead of the floating spar and it has less dihedral. It had quite a bit of power and also had unlimited vertical. I think they said the got one 23.5 pounds with a 3W 75 and smoke. Plus it is alot cheaper than a DA-100. Check out www.DRhobbies.com.

I just sold my 2.6 with DA100 cause I went bigger, but I have flown a 2.3 as well and both fly excellent with the 2.3 being a snapping fool......it's like "BAM"! (sorry couldn't resist:D) But honestly if you can swing it go for the 2.6 with the 100. Bigger always flys better in the end...and if you have any IMAC aspirations you will find the flight line littered with 2.6s! Not that the 2.3 is a bad IMAC plane.....it's a great IMAC plane (in fact I have been beaten by one...bad![:@]) so it really boils down to the guy wiggling the sticks, but in the wind the larger plane always seems to get pushed around "less" and does tend to present better.

Oh yes, if you do go for the 2.6 you can definitely get away with 1 JR8611 or Futaba 9152 per aileron. I have flown it this way and cannot tell the difference between the single aileron servo or the dual. It's up to you and of course this is all predicated on using one of the "super servos" ........nothing less than 260oz.

Good Luck,

Flyboy2000,

I just finished building my 2.3 and actually had the test flight last weekend. The power is not an issue at all using the KS1060 pipe and a mezjlik 23X8 prop. I have a 12 page thread on the build along with Video of the test flight on my website if you want to take a look (www.billhigginsjr.com) The plane finished out at 19lbs 07oz and on the 8th run of the engine is turning about 6810rpm.

I have both the 2.3 with DA-50/pipe combo and 2.6 with DA-100. The 2.3 is hard to keep under 20lbs. You have to purchase after market c/f wing and stab tubes etc to lighten up. You also have to work hard to put all gear and batteries way up front to conteract the light engine. Bare radio equipement is a necessity. Hardest part is putting the rudder servo in front of the fuel tank. It is a blast to fly and easier to transport so it gets flown more than the 2.6. As for power ratio, yes you can hover in have good vertical but I alway wish I had a little more. As soon as the DA-75 comes out, been waiting, waiting, waiting!!!!! will immediately switch. Cost is also a factor, the 2.5 will be 500 to 1000 less to complete. As to which one I prefer to fly? No question, the 2.6. Perfect combination and a real joy to fly.

Now, that being said, I am waiting for the 2X2 Extra. That should have awesome power to weight ratio with the DA-50.

Well, I suppose I will be the only one saying I perfer the 2.3. I am not a IMAC competatior, and I have a Brison 4.2 instead of the DA. The 2.6 is bigger and presents better in the air but I find the planes fly almost idenicial but because of the expense and the ease of transportation I like the 2.3. The 2.6 with the DA has much more verticial, but the Brison does well also. I sold the 2.6 before it was built, but I have since flown it and either way you go, you will be a winner!

RE: CompARF 2.3 or 2.6
 

Flyboy, if you can get up here to the SFV (basin) you are welcome to fly my 2.3/DA50 19lbs6oz extra. I reallly love it and have way over 100 flights on it now. Bill Higgins is right, with the pipe the mejzlik 23-8 has more than enough power. It flys light and is easy to haul in my little car.

Have you tried a Meizlik 22X10? Mine seems to like it better. Makes landing much easier and better vertical. However, I only have a couple of gallons through mine. Just curious.

Paul, wow thanks. I think I would like to try it. I like the 23-8 very much but a better verticl performace would be nice.

Hi guys, I'm getting my 2.3 after Christmas and I'm putting ZDZ80 in the nose. Anyone tried this combo out there??

RE: CompARF 2.3 or 2.6
 

Fredo , I am doing this combo right now . Installed the ZDZ80 last week in the inverted posi .
If you choose to do this decide which pipe you are going to use because it will effect your
engine installation . I have gone for the MTW pipe which makes my header a tight fit , you
could try the bisson exhaust , it would make life easier . The rest of the installation is sdt .,

Merry Christmas . Stu
