RE: SNEAK PEAK: New 75-80cc YAK!!!!!!
I wholeheartedly agree we need more 75-80cc planes. There is just too large a gap between the poular 50cc and 100cc. Not all of us want or can haul a 100cc-size ship for regular jaunts to the field.
The ailerons don't bother me too much, though they are still honking big. I've been wondering why somebody doesn't wake up and realize that for below stall 3D crap, there is absolutely no need to extend the big *** ailerons strips all the way out to the tip. A tapered aileron like on this Yak put the meaty part near the fuse to engage to prop wash while minimizing the airleron tip cord to reduce roll sensitivity.

Hmmm. well if that size is what we want... 
Chip just told me about another new release....
the 94" CAP.... All you CAP afficianados will be cheering!

Any Idea on when he is expecting that plane to be released. Caps, edges
and Yaks are my favorites. It would be nice to see a cap in that size.

Anytime someone or a company takes a risk by putting something new out there we should encourage it...not criticize... so what if its different. At one time I thought all Yaks were hideous.... now I own two QQ yaks (one big, one small)... best flying planes out there bar none and the look has grown on me.
Its the flying characteristics that matters, so the ailerons are not quite scale.... if it makes for tighter control who cares!! Looks like an edge wing to me... not sure how that will fly though. The color scheme on this plane is pretty nice as well as the overall look....not too busy or garish. The covering better be ultracote though... if its Chinakote its doomed! I won't even buy a plane covered with Chinakote to strip... just not worth it....

RE: SNEAK PEAK: New 75-80cc YAK!!!!!!
Last I recall, Chip said all his planes were going to be UltraCoate covered.... will check on that...
Also got some info on why the ailerons are designed so.... he said another fella described the exact reasons and this is somewhat of a repost from another board....
The ailerons make sense. At post stall, anything out of the prop blast ain't doing a thing. At speed where does flutter start? (the tip) Big advantage is getting rid of mass at the tip. By reducing aileron mass at the tip you can also have your servo(s) inboard further cenered on square inches rather than having weight outboard. Less mass and weight on the outboard portion of the wing = faster stopping in rolls and snaps.

I like it!
Any idea what the wing area will be on that bad-boy?
What size of wing tube does it have? It looks smaller than the typical ~33% class frames would use.

Yeah at 94" (not 33-35% but more like 32%) it's more like the size of the Hangar9 Sukhoi... Perhaps a tad thinner all around. With the projected weight of 19-21 lbs it should offer a very nice wingloading and be extremely well powered with a 75-80cc engine.

RE: SNEAK PEAK: New 75-80cc YAK!!!!!!
I like it, and I totally agree with the theory behind the aileron design. Another thing to consider is mechanical advantage and drag - this design will probably produce more axial rolls and less adverse yaw or dutch roll tendancies.
My only concern is the length of that nose!!! Is it just me, or does that thing look loooooooong? Not only does it make it look kinda wierd, but it also will make the plane less directionally stable, no?

The nose does look a little long. I personally like the design of the aircraft
below for pure scale appearance. However, as someone mentioned earlier,
form follows function. If designing it slightly non-scale makes it fly better, I
am all for it.

The cowl does't look installed just taped to the very front former as far as it will stick out.
It's possible to get 1-2" shorter when mounting the cowl, as long as the canopy will still pull up, back and remove.
Certainly with a longer nose balance should be no issue huh?

Very nice looking plane! We need more planes designed around the 75cc-80cc singles.
Wonder what the price will be? This one will be on my strongly consider list. Can't wait
to see how it flies.

Anything in the 94" to 103" wingspan should fly great in this engine size. And I mean completely unlimited!

RE: SNEAK PEAK: New 75-80cc YAK!!!!!!
I like the looks of the composite planes, but I would rather stick with the balsa planes.
The GP cap is a bit heavy for a single. I'm sure it will still have unlimited even weighing in
near 30 lbs but not quite as good as something in the 22-25 lb range. As for the H9 33%,
the only one I really liked was the CAP. I don't care much for the looks of their new
edge or the extra. Bottom line is, we need a better selection in the 21lb to 25 lb range. I
am in the process of building a WH 33% extra 260. It should be great with an expected
weight of 22-23 lbs with the new 3W 80Xi.

RE: SNEAK PEAK: New 75-80cc YAK!!!!!!
I can't believe that everyone is complaing that everyone is making a yak!!! Last year everyone on RCU was begging companies to make Yaks!!!
As for the nose, I suspect that this is function over form as well. Hopefully, this plane is designed around lightweight engines while balancing without tons of work, like RXs on the firewall! In order to make a Yak balance with a light motor, you can move the wing-tube aft (reducing tail moment) or you can extend the nose. It looks like Chip was shooting for better balance.
I think I'll be buying one of these, especially is the price is proportionally less than his Extra.

My GP Cap is currently at 25lbs with a 3w106, a little more thinking and this plane can be at 22lbs with a ZDZ 80, even less if you got out the dremel.

BTW, my 25lbs GP Cap is my fault, I was lazy and did not want to think and make it lighter. I just wanted to fly, but after I repaired my 103" wingspan 21.65 Yak, that heavy Cap sure made me appericate my light Yak!!!!
We all love foamies, but wow, a 2.6m foamie is crazy!!!

Photos and info are just in from Chip. Not even on the website yet...
75-100cc engine
94 inch span
19-21 with a 75cc single
21-23.5 with a 100cc twin (Chip says way overkill)
I'm told this new Yak will be in stock sometime in February... Can you guess what 75cc engines might be available by that time???

Hey Maudib, here is a good engine for this new airplane.

RE: SNEAK PEAK: New 75-80cc YAK!!!!!!
Interesting... yet another 80cc offering... seems there's something for everyone.
It's $65 more than the ZDZ80 though and .7 lbs heavier (unless their quoted weight is WITH ignition which most do not).
I wonder what a DA-75 might weigh and cost?
Still for those looking for an alternative... you got one there...

Correction, our EVO rear carb is only $25.00 more, the side carb is $65.00 more.
Just to keep the record straight..and this is comparing the old ZDZ 80 and not the new and latest. which is more expensive.

RE: SNEAK PEAK: New 75-80cc YAK!!!!!!
It looks fine to me. Good ideas all the way -note also the model is "square" same span and overall length -This is a well proven setup.
the weight /size is what I would do -and have done - an 80 in a 18 lb plane is just lovely -
My piped 40 in a 1280 sq inch 11 lb setup also was "just right "
so far there has been NOTHING on the market in this size with this kind of power to weight and low wing loading
That size and 17-18-19 lbs on an 80 (dune it) is just too much fun -I bet Chip sells a lot of these.
The reason more models like this are not on the market is simply that many new flyers buy these and promptly thrash em-then blame their lack of abiluty on the model.
My EF Yak is as good as I have seen-up till now in the weight/area power game (piped 50 ZDZ)
My new 260 H9 is also quite good 11.5 lbs on 1135 squares
The Ultra 202 at under 11 lbs is another very good one one - their LG setup tho is simply not for rough fields or new pilots . needs to be piano wire . why but the plane when a gear that simly folds up is a lot easier to fix. (it is also about same weight so don't think it will be too heavy - weigh em)
