Stock battery dimension? Great question! I was wondering the same thing. The e-flite site does not list the dimensions of the battery. At 60oz, 2:1 thrust to weight and a 48" span, this plane is going to handle wind well. 5-10 mph with my PA Katana and it gets packed up. Durable, and flyable when my balsa planes in the same size are not. Sweet.
If you would like to donate to the tele1974 carbon Z yak fund feel free to pm me and I will give you my paypal account.

Do you think that landing gear is going to hold up on a grass run way?

Probably. My ParkZone Extra 300 gear is holding up fine flying off of rough grass in a park.

Would be nice to know what cheap batteries will fit, or if those with Habu batteries could use them for longer flight times. The stock battery should be a decent indication, but battery slot dimentions would be even more useful. I would love to know if I can work out a common 2650-3,000mah battery that I can stock up on to fit all my 4 cell stuff, of if I am looking at spending hundreds for a total of 20 minutes worth of flight time on some odd sized proprietary battery, it is a given the 2800mah stock batteries will be hard to come by for a while once it is released. It kinda sucks having only a single battery for weeks until spares get out into stores, or a decent alternate is released ala blade 120SR.

I do think this is going to be good in the wind too. My PKZ extra can handle an amazing ammount of wind for it's size, plenty of power, very manuverable, and a little on the heavy size, instead of fighting the wind, it makes it easy to use the wind for aerobatics. From the looks of things the Yak will probably fly similarly, although a little more floaty with much better slow and post stall flight charachteristics with a lot more control throw and power.

As far as the gear working well on grass, it remains to be seen, but it looks tall, wide and raked forward quite a bit, good for prop clearance and stability, same wire style legs that my Extra has, plenty of spring to take the shock of hard landings. The wheels should be 2.5"-2.75", going by relative mesurements of the side profile photo on HH's website, it shouldn't be a problem, especially with the pants that look pretty narrow, they help cut through grass a bit better than the wheels alone. If the wheels are smaller, and there is not room in the wheel pants for bigger wheels, then it is pretty easy to just stick a set of bigger wheels on, although it doesn't look as good. I've had very good luck in the grass with my extra wearing 2.5" wheels raked forward a bit more than stock, and a 1.25" tailwheel, coupled with full high rate up elevator and a 10.5" prop it rolls great in the grass.

The good news about these foam planes is that if the battery compartment is too small, you can cut out the foam. My son had a Super Cub and I did this to fit in 30C batteries, though I needed to use a dremel no the plastic. If the weight of the battery is too different, though, and needs to be repositioned significantly to keep your CG, that could be a real issue. The picture makes me think there's room to move forward for lighter batteries.

I decided to pre-order one of these today. I think these are going to be popular so I wanted to "get in line" so I can get one of the first ones. I also hope to have it for my Christmas vacation. I know HH doesn't have a very good track record for delivering new products, especially around Christmas, but one can always hope...

I bought a Turnigy Nano-Tech 2650 35-70C for $30 and looks like it will fit fine. Unfortunately, I decided to by an 89" Slick instead of this plane so I don't need this battery and it is currently out of stock. If anyone is interested in buying it, PM me. It has never been out of the box other than to measure it.

From physical measurements (ie, actual not from specs):

L = 136mm
W = 43.4mm
H = 22mm

290g

I'll take it if you still have it.

I can't wait to replace my Extra 300 with this plane, looks like a logical step up for me.

I saw a thread on the little Champ where a guy listed all the parts to make up a BNF version of the Champ. He saved about $25 dollars off the total price not needing the TX or charger, those ugly/terrible wing decals and so on. Some may say its not worth the hassle but other people like saving $25 bucks.

I have recently moved from EPP 3D planes to balsa and found the leap of faith to be more than I bargained for. Flying EPP is like working on the simulator. No worries about crashing = great close in flying. Flying balsa now has you up about 3 mistake high. My light weight balsa has me fearful of a minor bang putting me into a major rebuild.

I'm wondering if this plane is a 1/2 step from foam to balsa. The floaty easy to fly foam with the ability to take a small hit and ding rather than crack, over the precise balsa with its superior lighter weight/size but at the expense of fragility.

It certainly looks like the best foam 3D model I have ever seen. True Horizon solution. From the box to the field in record time while containing the best mass production components.

Project triangle in Horizon's view - Fast is from the box to the air and also from design to delivery of product.

FAST - GOOD - CHEAP = Pick two

Yeah... I've been wondering that as well. I've gotten a ton of comments & questions on this plane as a "transition plane from epp" on my blog as I'm a EPP blogger www.3dpastor.blogspot.com but personally, I'm still not sold on it / I still prefer the epp options available in this size range. I think there are planes in the same size range, made of epp - that are just as good performance wise, yet retain the resilience of epp - and are cheaper! :-) For instance, The Bouncer from tufflight.com is my latest build - and I find it more than capable. Put Quique on the sticks and I'm sure he could make it look as good as his Carbon Z. :-)

My 2 cents. lol
