georgerm, I'm glad you were able to get the wings fit up right. The Yak is a whole lot different than a small flat profile plane for sure. I think they're both fun in their own way. It's nice to have some of both styles to keep things interesting.

Finally got mine put together and flown today. I went with all cheapie mg servos and a BPHobbies 2207? 950kv with a 10x4.7sf at the moment. I really need to try an 11 incher because it not very snappy at all right now. It'll hover it but with little to no pullout. Will probably wind up with my Park 480 on it eventually. I'm using Gens Ace 1500s and never even checked the balance but it feels pretty close. Was much too windy to really be able to dial it in properly but I like the way it flies. No sign of any bad habits which gives me confidence to fly it much too low for my skill level. LOL By far the easiest kit I've put together. I love the servo arm extensions but don't like the non swiveling push rod connectors. Went with Dubro stuff there. I used Stick and Seal glue for the first time on this plane and I really like it.

Assembly doesn't get much easier for sure. I've used Stik 'n Seal on quite a few EPP planes and it's held up great. I use Welder more now days, but mostly because it's easier for me to apply with the thinner density and long applicator tip. Definitely try an 11x5.5E or a rigid 11x4.7SF prop on the 2217 950kv motor. That should be a nice improvement.

Went with HK 13g digital servos, and at first a 100 gram out runner pushing 230 watts spinning a 12x6 with a 30 amp esc and 1800 Nanotech 25-50c Turnigy batteries. The Yak flew fine, but being at altitude it would hover. When I would try and punch out It would climb another foot and that was it.

So swapped out the out runner and ESC. Now running a Gforce G10 3715-1100 kv out runner and a 50 amp ESC. 460 watts pulling 37 amps spinning a 12x3.8

RTF weight is 31.5 ounces, and I'm getting 4.5 minute flights with 11.40 volts left in the Nanotechs upon landing.

Fun plane!

Hi,

I bought mine built (i.e. secondhand) and built not so very well. After two or three flights, did the following:

1. Removed the drek ESC and replaced with Castle Thunderbird 54
2. Removed the HXT900 servos from the ailerons and replaced with Savox 0257
3. Removed the RCtimer 3536 motor and replaced with Turnigy SK 3542-1000
4. Removed the battery from behind the motor to above the port wing
5. Closed the battery bay with a block of fitted EPO
6. Gorilla-glued the bits in place
7. Strengthened the landing gear

The plane flies like that mouse (from Hoodwinked) on coffee, using an APC 12x6 or E-Flite 12x6SF props

Kevin, any thoughts of carrying the 2217 950kv motor? I think the lower kv is better for 3D, at least that has been my experience, plus, I do not think it has an issue with the 11 inch prop.

Here's a picture of my Yak. Got an Exceed RC Optima 480 3010-1020KV on it. It flies heavy but handles just fine with some speed. It flies great @ night

I have thought about picking up the 2217 950kv. I will bring them in soon. I'm going to build my next plane of this size (SU-31) with the 2217 1100kv. It should come in at closer to 22-23oz and be a real floater, so something in the 950kv - 1100kv would give me nice thrust with decent flight times on a 1050mAh - 1350mAh battery.

Nice, I need to hook up some lights.. Though I won't be in a tee shirt when I fly it (coldddd). I need to move to AZ.

Got mine in the air for the first time today.

Powered with KDA 22-20L from HK, http://www.hobbyking.com/hobbyking/s...r%5FMotor.html

Plus MG14's all around and 3s1300mA Lipos on 30A Plush ESC.

What can I say about this plane, I put 6 packs through today and every flight just feels more comfortable and easy to fly.

I did notice that the 130mm CG they recomend is damn hard to achieve so I just left it.

I have a hell of a belly pitch on knife edge which is usually from CG being too aft, but I'm going to drop down to a slightly lighter and more powerfull motor and see how things balance out after that.


One thing I wanted to check, did any of you guys add some right and down thrust by putting washers behind the motor mount for this plane?
