RE: Extra 2X2
Is the OS 1.40 RX similar in power to the YS 1.40 DZ?
I was thinking about such a setup for the CompARF 2x2 and a YS I have lying around and wondering if it is realistic for IMAC. Not really looking for 3D insane power at this point in time. DA50 on 11lbs. is not exactly my idea of fun... Thanks. __________________________________________________ ______________________________ ORIGINAL: Buzz Lightyear Hi All My 2x2 has flown. I built it with an OS140RX to keep it light so I could use it as a backup Pattern and backup IMAC model. I put ALL the servos up front and used a bell crank pull pull for the elevator. The model weighs 5.4kg with a lipol and 300g of nose weight. I took out the lipol and nose weight and replaced it with a 340g 6V 2400mah nicad. How does it fly?...............beautifully!!! It will fly F3A and IMAC. After flying it around to see how it rolls, loops, snaps and knife edge looped, I pulled vertical did a 2 of 4 and positive snap in opposite ..............easy! It balanced well behind the recommended cg range. It will fly inverted hands off. I would prefer it to be a little nose heavier, but at this light wing loading it doesn't have a nasty bone, so I'll leave it. Cheers Buzz |
RE: Extra 2X2
Has anybody had any problems with the canopy coming off in-flight. It happened to me today and I was wondering if you guys and any suggestions on how to fix that problem. Thanks
|
RE: Extra 2X2
No canopy problems ( saw that coming with the ' instruction installation' I used the 'hook' at the front of the canopy, and used the same mounting method as the cowl, one either side, about half way along the canopy, the rear of canopy same princible, one hold down.
Can post some pics tomorrow. Good flying Tony |
RE: Extra 2X2
Thank you! I'm pretty sure I know what your talking about, but pics would be great.

Hey Guys and girls... first post to this thread.... I am about half way through building mine and thought you all might like to see the scheme I am putting on it. It looks a lot like a Yak because this is my "back up plane" to my 2.6 meter yak =0) Let me know what ya think!
Scott |
RE: Extra 2X2
I like the shceme, great job!
|
RE: Extra 2X2
Really like that scheme, very ' Yaky':D anything done to the fuse...?
Tony |
RE: Extra 2X2
Thanks,
Glad you guys like it. I will be tackling the fuse next... will look a lot like the "yak scheme" as well. Black triangle deals in the back with a silver stripe. I'll post another pic when its all done. Thank God for Vinyl graphics lol. See Ya! Scott |
RE: Extra 2X2
Plane looks great...now is anyone up to answering my question! (somebody is going to have to step up to the plate on this one....).
|
RE: Extra 2X2
I am using as much throw as I can get. My up elevator on low rates is set so it doesn't snap. I started with factory specs and went down from there. The down throw is a little weak but again I went with as much throw as possible. Ailerons were factory specs on low and as much as I could get on high.

RE: Extra 2X2
Hello guys I'd like to know if this plane screech when it rolls fast, like the big 3.3 (42%)comp arf yak sp, Thanks

RE: Extra 2X2
It sure does!

is there a sound/video of this thang?
I like to hear it!!!!!!!!!!!see theres something about this creeming sound that i like very much. please show the link of the plane sreeming, fernando |

Finally got mine done. Hacker C50 15XL Evo20 5000mah lipos Acro 90 ESC 22x12 APC-E.
After a few CoG + thrust line + UC issues is now flying well. Makes me look far better than I am[8D] |
RE: Extra 2X2
Has anyone else put Graphics on their 2X2 Comp-ARF Extra ??? Would like to get some ideas for Graphics / Stripes / Design ??? thanks, zz |
RE: Extra 2X2
Hi guys!!
I have a piped evolution g26 and some hitech 645 servos. Will this stuff be large enough to fly this plane? I'm thinking of purchasing one but I'm all tapped out. I can't aford all the fancy stuff for it yet. Thanks!! |

I have the MVV6 1.60 (G26) on Pitts muffler in a Wild Hare Edge 540, performs well ( only 50 sq ins less wing area than the C-ARF 2x2 ) Good flying Tony |
RE: Extra 2X2
Thanks Tony!!
Looks like I'm purchasing a new toy:D |
RE: Extra 2X2
Does anybody know if its possible to get a clear canopy for these models yet?
Cheers Chris |
RE: Extra 2X2
Sounds like the EVO 35GT with a Bisson Pitts muffler I have sitting around might be a fair power plant for this light weight airframe (3# 12 oz w/ muffler). What do you folks think? Sure would like to find a home for this motor... doesn't seem to be many planes designed for 35cc.
Thanks for any opinions: BP |
RE: Extra 2X2
What did your electric weigh?
Thanks Chris |
RE: Extra 2X2
So here are my thoughts on this one. Instead of putting a heavy gas engine in it, just do an OS 160FX with a Slimline Pitts muffler. Keep the weight down and it should be a great IMAC flyer. I have no intention to do all out 3D with it. Single Fromeco 2400 maH Relion and Hitec 5985's on the control surfaces.
On another note, you could also do a tuned pipe. Does anyone know anything about tuned pipes on an OS 160? |
RE: Extra 2X2
Hey I am highly looking at getting the 2x2 CA extra and I was wondering the price differences from electric an gas. I have never built a plane this big so hopefully i can get some help and insight from you guys.
Thanks, Greg |

Just put a DA50 on it...it needs the weight in the nose. Or else you got to move the elevator servo's upfront like Buzz lightyear with the 140rx. The wingloading could be less, but it's not really a problem, you can still have a lot of fun with it!
Are any of the 2X2's in this thread still flying? Seems a bit quiet lately ;) Anyway, i had some fun with mine this weekend!!! Greets Gaaaz |

Finally took the time to make a short movie of the 2x2

RE: Extra 2X2
VERY NICE VIDEO GAAAS, PLEASE TELL ME WHERE ARE YOUR CG, HOW MANY INCHES NEXT TO THE FUSELAGE.
THANKS SERGIO |
RE: Extra 2X2
Good video Gaaaz...[sm=thumbs_up.gif]
Good flying Tony |
RE: Extra 2X2
PLEASE TELL ME WHERE ARE YOUR CG, HOW MANY INCHES NEXT TO THE FUSELAGE. You can check your CG by flying a 45° upline (crosswind, so that the wind has no effect on your upline) do a half roll (invert the plane). your plane should now keep on flying the 45° upline or descent a little bit without elevator input. If your plane goes up, the CG is too far backward, if the plane goes down, the CG is too far forward.... keep on flyin', Gr Gaaaz |
RE: Extra 2X2
OK GAAAS
BUT ON YOUR VIDEO ITS SEEMS LIKE THE CG IS REAR ,,, OR YOU ONLY PUT LIKE YOU TELL MI???? |
RE: Extra 2X2
I don't really understand what you're asking EL ****CANO, but i think you wanna know if i change my CG for 3D-flying. The answer is NO, i'm not a pro, just a sunday-flyer, i just take my plane and go and have some fun in the weekends so i don't bother if my CG is a bit offline...
By the way, more about the CG of the 2x2 is on page 6 of this thread... Cheers, Gaaaz |

RE: Extra 2X2
I have a 2x2 that I put together this summer. It's a nice flying airplane however I am having some tracking issues in knife flight, it pulls to the belly. Invert flight is nice, all most hands off. I set it up with 3 degrees right and 1 degree up thrust. running a DA50 22X10.
wing and stab are at zero incidence. I added a rudder elevator mix to help correct the tracking in knife edge but I would really like to know how to adjust the plane so it will track straight with out any mixes. I'm looking for help or suggestions. Dave |
RE: Extra 2X2
Ijust picked up the 2x2 Extra and the workmanship is really nice. I am new to composite planes, I tried to dry fit this plane and noticed that my HORIZONTAL stabs are not flush, especially the port side one. There is a gap of about 1/16" (the leading and trailing edge) and I would like to know if its because of a mere dry fitting or there is something I need to do to make it flush. Any input would be great.
I think my plane will be coverted for EP. At about 13 lbs she is perfect for EP. Thanks guys!!! |
