No sir I dont actually, I havent even seen a 100cc Comp ARF Yak55, I have flown the 3.3 though. And BT terry is right , they are not arf's by any means, its a painted composite shell, everything else is left up to you.
If it were my $, and I wanted a new 100cc plane right now and liked yaks.....its gonna be an Extreme 110" hands down, I havent flown one or even seen one personally, other than detailed pics, but from the people I know that are in the know, say that this plane is unbeatable for now. I hope this helps, unless you build, in todays arf world, its getting harder to find a truly badass plane from my perspective (light weight), and I believe that Mr. Hinson is heading in the right direction. Because whether one believes it or not, lighter flies better, all around the board. I just wish I could convince people to at least try it once. Once I was shown and taught this, there is no turning back, just look at the weights on the top pilots planes, they are slowly but surely coming down. I am being taught by someone that builds the lightest planes on this continent, and Im learning fast...lol. JMO

Uhhh...NO

Heres the deal, these are ARF's assembled in China, not one off kits that are built with pride by the owner or a profesional builder with a rep. QQ is world class and he has Mr Ulrey on his team, these guys know how to design a good plane, and if it were possible to get these planes as kits, then theres no doubt they would be flawless like any other kit built with pride. BUT.....these people assembling these ARF's dont know squat about building a plane or why something needs to be done a certain way, they are simply doing a job to feed their family. They could care less if there is a proper glue joint or its perfectly straight, they are forced to build as fast as possible. I had a GenII 102" and I was super stoked about having one of QQ's planes a couple years back, but when assembling the plane, nothing and I mean nothing lined up, we had to redrill every hole for the screw in the stabs, LG ,TG anti rotation pins, cowl, canopy, you name it , we had to fix it, wing tubes didnt fit, sockets were broken, I even had broken ribs and socket in the stabs. BUT QQ quickly took care of my needs w/o question or hesitation, he went above what he had to in order to make the customer happy. Once the plane was done, it was awesome, never had a lick of problems with it structurally, the covering gave me fits regularly, but no biggie. I wish I hadnt sold it when my big Yak was done, I actually miss it. I had many people tell me the same thing , that they had zero problems with theirs, ever, so I still contribute the problems I had to the person building the plane at the time, not QQ aircraft. That being said, its an arf, your taking a chance on getting a poorly built plane by someone over there that could careless. But thats a chance we are willing to take with any plane I guess. Of course, this is JMO.

I would highly recommend the EF 110" Yak. I have 48 flights on mine, & I absolutely love it. I do mostly sequence stuff, with a little 3D thrown in. I know there are other good quality 100 cc arf's out there, but I can't imagine any flying any better than this one.

How do you like the comp. pipes, hows the transition on them?

You Definitely have an awesome set-up. I hear the weather should be nice sunday.

I believe the QQ 102 does have some dihedral and it is needed to fly as well as it does. My gen 4 had very little rudder to ele in the neighborhood of 3 or 4% and rudder to ail ~1 or 2%. It flew really good as soon as I got the correct cg it came to life. But like any product im sure theres got to be a lemon every now and then and companies like EF, QQ, Horizon, and DA take care of these when they pop up.


Edit: The dihedral in the QQ yak isnt for better up right flight it is to balance aerodynamic forces so the plane flys it best in all areas of aerobatic flight. Its not a neg aspect of the plane at all.

Those companies I list aren't the only good service companies they are just the ones I have had experience with.

[MikeC3D]

I dont think it does, but I'm willing to be wrong. How do the wings go on if the tube is straight, cause the holes in the wing ribs look centered to me. JMO

[Flatlandman]

Its a small amount but its there. I dont have a good pic of it head on but you can see it in this pic.

[3D-Seth]

The QQ 102 does have the slightest bit of dihedral, not much but a very tiny little bit.

[customjrod]

Mine has more than a very tiny little bit.

I am very pleased with them. The transition is quite positive & very smooth. I like them so well, I am ordering a set for my QQ Python/BME110 combo. That should be fun.
Let me add one other thought. This engine does not care what attitude the airplane is in. It runs smooth & flawlessly throughout the throttle range. A real delight to fly.

How much dihedral does it have? It should only have a couple of degrees (not sure of the exact amount, but its not much at all). Just as Flatlandman said:

Its there to help, unless the people in China did something dumb and made it crazy off (like 15º or something stupid which I'm sure Quique would have corrected the issue if there was one with the airplane).

I'm not trying to argue or anything, just trying to figure out why there was so many problems with it. Both of my 102" Yaks flew/fly extremely well. My Gen 2 had to have had at least 600 flights or more, and never missed a lick. My Gen 3 is probably close to 4-500 by now, and it hasn't had any problems either.

The EF Yak is an all around performer. It is a 3D monster and IMAC's very well also. It does take a little bit of mix on mine to get it to knife edge straight. I am probably a little on the tail heavy side though.

I am running ES Composite pipes on mine with a DA 100. The pipes were a little tricky at first but after moving them back a bit and some throttle curve adjustment I am finally very pleased with the midrange on it.

[BreadBowl]

Actually dihedral is necessary to help eliminate roll coupling. Leading edge sweep augments dihedral, and with the Yaks having straightish wings, it will need some. For wings with more LE sweep, they may not need as much.

Typically, the tops of the wings are flat, and the bottom of the wing has the dihedral caused by the difference in thickness of airfoils. I have yet to see any problems with construction of Quique's airplanes, and I've messed around with quite a few of his prototypes. Even they were good. No ARF will be perfect, but QQ's are real good. They're no worse than any of the other high quality ARFs on the market today.

FWIW.

[customjrod]

So many choices.Im still not sure what to buy. I love the thoughts of the 110" extreme flight BIGGER IS BETTER. But the comp arf 55 is realy catching my eye, if you dont crash it, it will last forever.
