My friend put a ZDZ super 80 in a 87" Yak and it flies like a foamy. This plane should be light

I just recieved mine today, and am very impressed. I've built 2 QQ 102" Yaks, Aeroworks extra 260 etc, etc... Let me tell you this is the lightest airframe yet. The construction is great. I do think the rudder and the elevators look cheezy, they could have thought that out better. But overall, Outstanding. It even has the firewall dowelled for strength. My only complaint is the checkerboard on the covering. It's not covering, its a vinal like sticker and melts when you tighten the covering.
I'm going for light on this one, 1 aileron servo per side (ailerons seem stiff enough), and 1 rudder servo.
Guys, this is not the plane for a 100cc twin. It will be ballistic with a DA-85.

(MIT) i just weighed my 80 twin 5lb8oz with ignition & exhaust and will fit the cowl what you think weight ok

If you can get it to balance go for it.

I didn't notice this plane on Laniers web site, was it a new design?

Weighs about as much as a 100cc ... but the plane has the wing area to support over 20 lbs., ... so go for it.

I'll be building on my Yak, but I'm anxious to see someone assemble the plane so we can see what it really looks like from various angles.

RAMMJETT

i just checked the weight of the da 85 weighs 4lb5oz stripped i am guesing 5lb at least with exhaust and ignition.i wanted one for this plane but i don't know.might be hairy on sutch a light plane

RAMMJETT

my da 100 5lb 12 oz no ignition no exhaust

well, my opinio of a heavy lanier airplanes is because, I have a Yak 87, One guy in my club had the same with a zdz50 I thing and the plane for me was like you guys said a foamy but he has to modify the plane for a final weith of 17 lbs, without any mod the planes was coming out at 18 to 19 LBS, a dog for any 50cc, but anyway, it was a video of someone in f l y i n g giants with a 87" yak and a 80cc 3W and you can see that the plane was exelent with this conbination.
Extremefly, BME yaks come out of the box with a final weith of 16 LBS, so I was thinking that if the 87" lanier comes in 18 without mod, a da-85 is exelent, I don't know if a DA85 will do extreme 3D with this extra, but they said that DA-85 put equal or more power of a 100cc, in my case I got a 100cc and for me to invest 900.00 dollars in another engine will be crazy, like I said before I will have to sleep inside the plane LOL.
DA-85 look to me from previous forums the right choise for this airframe, I was impress with the aileron wau they are huge. I will put on this plane hs5945 all arround, but that's my choise.
I noted the servos in the back of the plane that will help a lot with the balance.
troy build models has a nice chart for weith versus wing load and %, to have a point of reference.
please do not fallow my steps, my plane with the 100 CC is experimental LOL.
One thing is for shure, this planes a build for 3D, and they float and float at landing, most crash happen in landing with this airplanes, because people are no use to them, some people do harrier landings to hard, some over run the runway, some just can't landed, LOL,
I hope after I finish this plane will do like my other planes,.
The only thing I worry is the prop size if this plane have clearance for a 27X8 prop, then and only then will go with the 100cc.
But please do not take my advise!!!! I over power all my planes, and they all fly beautiful. This are some examples of the planes and setup's I got at home:
Hangar9 Funtana, YS120
Kmp edge DL50
KMP extra 330 DA-50
Nitro Model Yak 54 .50 ys63s
Great Planes Ultimate DA-50
BME Yak 54 DA-50
this airplanes fly like foamy's , I will be open eyes to see what can be done better with new extra.

If you guys have any doubts about the DA-85 having enough power here is from this weekend. The plane is 102 inch wing (35%) and weighs near 23 lbs. The engine is brand new and still running rich but still puts out 6900 on Vess 26A. Yes we are at sea level here but with the smaller plane (94) it should be wild power.

Maxun, the reason the 87" Lanier Yak flies so good with a 80cc instead of a 50cc is because .... It is in fact a 80cc plane! This plane is much bigger than the normal plane that is fitted with a 50cc engine. Lanier ... in my opinion shot themselves in the foot by ever putting 50cc -80cc engine required. They should never havce put 50cc on the box at all. That 87" span is deceptive ... because thisplane has a very deep chord. Its an 87" span but the total wing comprises the wing area found on planes with over 90" span. This plane has 1450 sq. inches of wing area, and a fuse that is very wide. This size plane used to be flown with 3.7 and 4.2 ci. engines 10 years ago. Most 50cc planes today usually have between 1150 and 1350 sq. inches of area. This 87" Lanier Yak was mismarketed, and people went out and bought it thinking they could drop that 50cc engine that they had on their other 87" 1250 sq. inch plane and have the same performance. Well this 87" plane has 1450 sq. inches !!! .. and 84" length! so, .. basically when the truly 80cc plane came out weighing more than a 50cc (labeled) plane should have ... everyone started calling them heavy.

Mitsu you are absolutly right, the 87" was mismarket.
Mitsu I got a Laser 87" scrach build by a master builder finish flying weith is 16LBS, with a FOX 50cc (Brison) and all the custom decal from kirby, like the one you have in your handle picture. How the laser fly?, did you fly one before?, My still in ARF because I told the guy not to finished do to space at home so still in ARF condition, is beautiful but I lost the interest to finished. can you answer my question. Sorry guy's this is out of this treat. (extra 330). Sorry.

I just recieved my extra today!....

Everything came in imaculate except the cowl had a warp and some minor cracks.....Very difficult to get on the plane even when heated....
I will call Tower tommorrow.....

This plane IS much smaller than the Yak 94" I agree with MITSU1......

The airframe is SOOOOOO light it is UNREAL!>...

I feel like a 50cc would power this plane.... I am not sure that the wingspan is 94" but I didn[t check it ....

Everything fit perfect (minding the cowl) and Laneir even packed the wing box differently than any other plane in the 50cc or the 94".....
They packed the hardwere in the wing box and had split the alerons from the wings and even had a separate support to keep the wings from moving while shipping!....

The internal structure is the same as the edge 94" so there will be no issues of reliablility with this airframe......
It should hold up great.... I will be giving the epoxy treatment from behind the firewall all the way back to half the fuse....OR I may add some stock to the sides...

This may be a moot point though, due to me making a tuned pipe or canester tunnel....
THis will provide plenty of extra strength to the fuse, and if done right, not much weight will be added to the airframe...
Unfortionatly I do not have a Laser cutter though
I think I may have access to a cnc machine ! I believe I could cut some aircraft grade plywood and balsa with that though.

This plane will be a real hoot to fly...

I may pick up a 80cc 3w for this one or even a 75cc.... This airframe will not need much to make it fly....

My Yak will take a 80-85cc as it is bigger and will weight slightly more....

Justin

Side note on the 87 Lanier planes............

They also got themselves in trouble by CLAIMING the wieght would come in at 16lbs!!!!!!!
That is why the got themselves in trouble as well....

I have to agree with Mitsu. Saying this plane is heavy is utter nonsense. I'd love to know what he's comparing it to. 20-22lbs for a 94"plane is not heavy.
Never mind, I posted this before I read the whole thread.

Does anybody have a picture of the underside of the wings?

Pic taken from the Yak Thread. This is the underside of the Extra's wing. Compliments of Mitsu.

(DOPP) what do you think the best motor is . i am thinking da 85 but man 27x10 on this thing i don't know.

The only problem I have with the Extra is that all the wing and stab tubes are so tight I cant even get them in.

Maxun, the Laser in my avatar is a scratch built 85"plane from my own drawings. It has 1230 sq. inches span and is powered by a Moki 180. It weighs a very light 13.5 lbs and flies incredibly. I met Leo Loudenslager at a Memphis airshow, and he let me crawl all over his laser with my camera. My Laser is the most accurate scale laser I've seen ... but I may be a little biased.
.. To answer your question though ... Lasers typically are very, very true flyers.
