RE: 47
I completed my yak this weekend without too many problems, the main problem area is getting the wing tubes into both wings without them sliding farther into 1 wing or the other. I think a stop in one or both wings would have helped out there. The other problem occured when I was tightening the wing bolt down, about 5 or 6 threads in, it would get real tight. Over and over I tried with the same results, so I gave it a few more turns and the wood block holding the blind nut broke off. So after a quick trip to ACE the problem was solved, I grabbed a new metal bolt and nut, cut a hole in the other wing so I could get a wrench in there and cranked it down.
So off to the field I go, new plane and battery and a well seasoned Os 55ax, (off my F-22) turning a 13x4w apc prop. The temp at the field was a sunny 37 degrees with about a 10 to 15 mph wind. Filled it up, taxied out and into the air she went, I just needed a little elevator trim and it was flying hands off, 4 minutes into the flight I called out no throttle control, but managed to get it on the ground without out any trouble. After landing the throttle control was back, but the servos was barely moving, grabbed the volt meter and the battery was under 5.6 volts and dopping like a rock. This is one a 6 volt pack, I checked it 2 mins before I took off and it was at 6.7 volts.

RE: 47
Was working on getting my Yak together today. As I tried to slide the wings onto the fuse over the carbon rods, the whole end of the left wing collapsed/crushed [:@]!!!! The fit is snug, but didnt feel tight enough for this to happen. CAUTION!

Will I be able to get the servo wiring in the tail through the fuse using extensions with connectors, or will I need to learn to solder for this one?

RE: 47
Could someone please post a pic of an installed OEM tailgear. Im not understanding how to secure to fuse using hardware I got with ARF. I was thinking of replacing with a Sullivan tailgear setup as Ive done with most of my ARFs....but not sure if I would get enough clearance for the rudder.

I used a Sullivan tail wheel on mine, i just put a small shim under the white plastic part of the tail wheel to clear the bottom of the rudder and it works great..

Where's the hatch on your Yak? (haven't built mine yet) It's easiest to put the rx right there where the hatch is. The left wing is a good place to put the battery in though to offset the weight of the engine being on the right side.
Are you using 2.4G? If not, the antenna can be run through the wing. Just make a big loop, out the end and then back through the other holes in the ribs.

RE: 47
Ive got the hatch on the left wing. Yes I am using 2.4....so both will be going in the same side. Ive too thought about offsetting the weight of the engine..so makes sense. The manual leaves you having to think for a bit before making final decisions.
Tip - worked for me - when installing the 2.4ghz receiver, I laid down two squared balsa strips and CA'd, then two more perpendicular strips over those just a little wider than the receiver. This allowed me to be able to set the receiver in over a little foam strip, and zip tied in place.
Thanks.

They made you think? Thanks for the warning when I get my Yak out of the box! A refund might be in order. Just kidding. It's a great plane, the best out there.

RE: 47
I now have 15 flights on my Yak and I have to say this is one nice flying plane. I am using a 13x4w apc prop and it seems to work well on my 55ax, its a little slow to spool up so I haven't had the best luck getting it to hover, but it will knife edge forever. I just purchased a 13x4 zinger and I hope to get to try it this weekend.
