Sounds like a load of something that smells bad. From QQ's site, the engine requirements for the 73" plane are:
Engine: Saito 180, YS 140, OS 160 or equivalent 26cc-30cc gasoline engines or Eflite power 160 for electric motor

The 69" plane has not been around for very long, and my guess is that there's too much excitement, and a growing market for 120 size planes, for this one to be discontinued.

But what do I know, I just play with flying toys

ArcherIIDriver

Yeah, I agree. & to be quite honest, My wife picked the plane up for me and this is what the LHS told her, so I'm not 100% sure if the communication between the LHS & QQAC happened before or after shipment. I will call QQAC 1st thing in the morning and my LHS to get this straightened out.

Just to be clear, I am in no way trying to start a rumor here. And, I am in no way bad-mouthing my LHS. I have full faith in both companies.

Just trying to get the facts.

Nothing wrong with the 73 if you don't mind running a larger engine. I bet that plane with an OS 160 or one of the larger YS engines would be awesome.

ArcherIIDriver

Yeah, the plane looks great. Would love to keep it, but I have a Saito 125 in need of a home...

The big difference I see between the two is wingloading. My 69" is 19.4 oz/sq ft and the 73" is 24.2 (w/ the lightest weight engine) - that's 25% higher. That makes slow flight / stall characteristics very different.

ArcherIIDriver

I agree 100% with TexasFlyer. The whole reason for me to retire the Showtime 90 and move the gear into this yak was wingloading. It had plenty of power (unlimited vertical even @ 10.5 lbs), but it just felt like a flying brick.

Funny side note - I think that I have a "problem" that is opposite to most of us in this hobby. My wife's response to this 73" vs 69" thing was "why don't you just buy a bigger engine & keep this one? I'm sure you can find something else for your 125!" Then about 10 minutes later she asked me when I was going to get something bigger, like a 85-100cc. Man, I love that woman!

You have to read between the lines. She's probably expecting you to get her a bigger gift, the bigger the plane you get [X(]

OK...just got off the phone with QQAC (spoke with Alicia and then with QuiQue himself...nice people)

The 69" yak is not in stock, it is no longer in production, and at this time they have no plans to have any more built.

Also, (just as we expected) the Saito 125 will not work in the 73" yak. According to "the man", it's not so much a power issue...but a balance issue...would take a pound of lead to balance & that is what would kill the performance.

I really hope they reconsider the 69". It is a great plane! Popular too.

Both planes will fly similar. Its a scale thing. 40% planes are in the neigbhorhood of 30 oz/ft of loading. Does that make them fly heavy. Nope. They fly like a foamie. My 50cc Yak is 26 oz/ft. Flies great.

Texas Flyer, thanks for your email and measurements. It may be possible to cut a little into the servo tray and place the tank above the wing tube socket. My 69" will be arriving next week, so we'll see.

ArcherIIDriver

Rajul,
where did you find one? I have called around everywhere trying to snatch one off some one's shelf. They all say that they drop ship from QQAC and were not aware of the discontinuation. I wonder if you'll end up w/ a 73" too[sm=confused.gif]

Mine was the very last one from the LHS.

ArcherIIDriver

I see you are in "Misery City"...if you got it from RC Hobby Shop in Sugarland, then you must have just beat me to it! [sm=48_48.gif]

Does anyone know if there are still plenty of parts available for this plane?

Just catching up on the thread...

Mike (Rajul): I didn't notice that you were in metro Houston, too. Jeff (ArcherIIDriver) is in N Houston, I'm in NW Houston, and you are in SW Houston. Jeff and I PMed each other and met face-to-face last week at the SPARKS fun fly & swap meet. Once you and Jeff get your Yaks ready to fly, we should all meet together and have a Yak-fest!

OctaneHuffer: Good point about the "scale thing". Having said that, if the 69" wingloading is 19.4, the 73" is 24.2, and the 86" is 26, then it seems that the 73" has a heavier wingloading relative to its size than the others. I'd expect its wingloading to be closer to the 69" since it is only 4 inches larger rather than the 86" which is 13" larger, but it isn't. I'm guessing the latest generation planes are just lighter.

Jeff: Too bad it is being discontinued. I fixed my undercarriage and it seems to work great. I'm trying an experiment, using only two aluminum screws vs 3 stainless steel screws. I'm hoping that if (when ) I have another really bad landing, that they will sheer before the undercarriage. Nylon bolts, even 1/4 inch, tend to break too easily. Hopefully I'll never get to test this but if I do, I'll let everyone know. All I can say is do what you can to reinforce the undercarriage before the first flight. I also adjusted the CG to be less tail heavy and landings are much more predictable now, though inverted flight is no longer neutral (was almost hands off).

What???/ they are disc. the plane?/

I though that this plane was one of there best sellers????????????????????????????????????????

Add another great plane that I will not have any parts for???

great

kochj

Consider it a favor.....

If you knew that a plane your JUST recieved , is now discontinued, and you will no longer be able to buy parts for it ( we all are going to have misshaps)
would you still want it????

kochj

Simply call them . The parts will probably go out the same day.

BTW their site says "to place an order email us" _____ I use the phone.

kochj

yeeehaaaa.....
Thanks ALicia!!

Has anyone had trouble with air blowing through the inside of this plane? Looking at this pic is making me wonder if the lightening holes leading into the cockpit should be covered...

Here's some pics of my almost finished Yak. The YS110 needed to be recessed becase with the Hyde mount the regulator was against the cowl lip and I really didn't want to cut into that part of the cowl. I also made a platform and moved the fuel tank back to the wing tube, I was worried the plane would be nose heavy but when I balanced it today without the rudder servo, reciever, and battery but with everything else it was perfect at 6 1/2", man I was happy! I'll be able to move the battery around to nail it when I fly.
