Gaaaz:
How good does your plane smoke with cannister? What kind of smoke pump are you running?
Thanks

Hello @ ALL !

"Looks like you completely removed the overhang flap, leaving about a 1" gap. Did you do the same with the ailerons? "

Yes its true 1cm (dont know in inches), same with ailerons, only then you get 50 degree of movement.

Ball links in combination with MLP servo arms are just the best you can take !

I would never youse the C-ARF method with the ...(? dont even know english word for the "things"). even secured with "Tygon" they open in Flight or brake.....


next week i ll mount the engine and Muffler (BMB - Andreas Brömer, best choice for perfect running engine), photos will come soon.


Thanks,Chris

RE: Extra 2X2
 

After much faffing about, many ‘diversions’, losing interest…losing flying sites…
I have finally completed this model…….!!!!!
And made the first flight yesterday......

For those who like details


Engine – ZDZ 50NG
Muffler – JMB ‘ Pitts Style’

Radio
5 x Hi-Tec 5945 Servo
1 x Futaba 3001 Servo
1 x Futaba 149 PCM RX
1 x SM services Engine Kill Switch www.smservicesuk.co.uk
1 x 6v – 2400mah Sanyo SC RX pack
1 x 4.8v – 1700mah Sanyo KR Ign pack
1 x 6v – 900mah unknown NiMH Smoke pump pack
3 x Futaba HD Switches

Smoke System – Pete Tindal www.petetindal.co.uk
Smoke Injector - O/D
Tank – 2 x 20oz Du-Bro
Prop – 23 x 8 Mejzlik Carbon
Spinner – Glass / Ali, Czechovakia origin
Fuel Dots – O/D

First flight was the usual mixture of nerves which turns into 'major grin mode' after a few minutes, despite all the 'cargo' of nicads/smoke system etc, which has made this 2x2 a heavier example, it does not fly 'heavy'.According to my scales, its just shy of 15lb 8oz, The ZDZ50 performed faultless, very serious 'grunt' will go vertical forever......:D

Good flying
Tony

@Paul Eagon.

I have a Sullivan Skywriter smokepump. Works very well with the mtw75 cannister. I use Diesel for smoke fluid.
On the previous page there's a pic of my engine, you also can see the pump and smoke fluid entry.

Gr Gaaaz

RE: Extra 2X2
 

Hi Gaaaz

Are you using 'standard' diesel or the ' bio diesel, & what is the comsumption like..? I use 20oz in about 4 minutes.

Good flying

Tony

RE: Extra 2X2
 

I use regular diesel, i also use 20oz in about 3 to 4 minutes. I also tried SuperDri. It smokes more, it's cleaner, but more expensive...

Q: Is it save to fly composite planes in cold weather? Doesn't the composite break faster (less flexible)?

Gr Gaaaz

RE: Extra 2X2
 

I do not think cold weather will have any adverse effect on the composite structure, if there is, I will soon find out as I plan to fly a lot over the next few month's..!!:D

RE: Extra 2X2
 

This thread made me wanna go fly [sm=tongue.gif]

A friend took some smokin' pics....

Gr Gaaaz (with smoke :D )

RE: Extra 2X2
 

Makes me wanna go fly too........:D

Looks really good, 'smokin Gaaaz'.

Good Flying

Tony

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.

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.

RE: Extra 2X2
 

Had to go to ' the hanger' to charge up...:D
Some pics -

Good flying
Tony

RE: Extra 2X2
 

That's awesome, I've got my new canopy and hardware on the way, thanks a lot!!

RE: Extra 2X2
 

Just finished my 2x2. Is everybody using the factory recommended throw rates and expo?

RE: Extra 2X2
 

As near as damit.. cant get more than 65mm throw on aileron, but it seems enough ( for 3D), flying mine @ 110mm mark for CG.
Whats the run down on your 2x2 ?

Tony

RE: Extra 2X2
 

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
