Hi Mark,

Can you tell us if they are on the water yet. I noticed the due date has changed on the AW website.

Jim


I dont believe they are on the water yet but they are getting VERY close.

Status: offline 		I need to replace my much loved Extreme Flight Yak 54 68"

I was flying it with a Brillelli 26cc, and it was a perfect match at 9 1/4 pounds.

How do you think this one will match up with the B 26 on it?

I'm looking for all out 3D power.

We have enough planes to fill all of the orders we have, no worries about not getting one espiacally if you are already on the list.

Chris
The 26 will be a good match for our yak. Expect to be about a 1/4 pound heavier due to the larger size of the model but this should not effect performance.

Just wondering which servos were used in testing and how they performed. This will be my first step up from a 40 size extra 300s. Should be interesting .

I fly at 8300 ft asl, and at this altitude engines are power downgraded by almost 30%. In such case i need at least 4.1 BHP which means a OS3500 however that engine weights 1350 grams (47,3 oz) vs. a DA50 that weights the same but with 1 BHP more, therefore sounds like a better choice. I know it sounds madness to ask this question but that`s the type of power penalty we have to fly around here in the Andes Mountains in South America. Would it fit?, What do you think?

PD: I have a 50cc yak with a 3W80cc and it handles well

If I remember correctly we used 5645's all the way around with great succsess. If you are looking to get the most out of the plane digitals are the way to go but any servo with 120oz+ will do just fine.

The DA 50 is to big for the airplane! There is really no way to get it to fit unless you leave the cowl off and then if you do get it mounted it will be next to impossible to get it to balance. I would go with an OS 1.60 and go from there. If you want to go bigger Satio has there 220 4 stroke that is heavier than the OS but still lighter than a DA. Weight is critical to airplanes and adding 2-3 extra pounds of weight will make it fly terrible.

Status: offline 		Hello, I just got done with my edge 540t 46/61. And i'm just waiting for this Michigan weather to turn. Anyhow, my qustion is, About this new yak! I've been looking for a nice little plane that i can through that O.S. BGX-1 3500. two stroke in. Its a little on the heavy side, 47.3 oz.w/o muffler. But it has huge power. 4.1 hp. Will this new yak handle that power, and the weight.? Any feed back would be great. Thanks.
