Thanks man the plane is just awesome. A company called AirfoilZ makes it.

I also have a new Yak Video


I uploaded my video to http://www.youtube.com/watch?v=3qjYhv3Hwjo


What can I say... I love my Yak. Yes it is true, this model is unreal and has be so well engineered. What I really like is the lack of pitch coupling which improves all facets of the flight envelope.

My setup is:
Motor: Hacker A20-22L
Prop: APC 10x3.8"
Controller: CC25
Battery: 3S TP 1320
AUW: 17oz

Anyone have "porposing" when slowing down for a landing? Mine gets a little funky when trying to slow it down for a landing. If I land it with speed, I can grease it in - but trying to slow it down too much gives me a "plop" style landing. Anyone got some setup ideas?

The flying is awesome though! I'm really digging how well it does everything.

Thanks
Terry

First check for any slop in your elevator linkage. Second I always fly with elevator/flap mix unless I am doing harriers in which case I switch to elevator/spoileron mix. The regular elevator/flap mix helps provide added lift if you hold a fraction up on landings and will make her glide in a slow down nicely, but if you crank on the up she'll slow down as you said.

Alternatively, use a spoileron mix for ultra slow and rock solid harrier landings. Remember to laterally balance your plane first. Also I use 45% elevator/spoileron mix on high rates for harriers.

yeah, or just take the gear off and land like this . . .

I'm not running any mixing on this set up. If you have servos that don't servo well, you might experience porposing. Or if you are too tail heavy you might get a touchy elevator. You can notice that mine tends to pitch down a bit at speed, I've got it right at my personal rear CG limit.

I'm at about 3.75" back on the CG... so close to tail heavy. The servo setup is great - no slop. It flies great at anything but the slowest speed. I do have a hard time with wing rock on harriers. Normally I've got the elevator-flap mixing on, but turn it off for the harrier.

Spoileron mix - this makes the ailerons go up with up elevator? I will have to set this up on the 8U - right now I have the switch up for elev-flap mix (elev up - flaps down), middle for no mix, and down for flaps. I've only popped the flaps down twice & didn't really like it - never tried it on landings.

Thanks for the help! Let me know if I should move the batteries forward. I have a 1320, 1500 and a 2000 pack, so the lateral balancing isn't the easiest. There's also more weight below the prop zero line than above. This would be hard to change - the battery might have to go over the wing.

Great looking vids guys, I just ordered one with the Hacker motor, can't wait to get this bird.
