Looks like the same line of stuff from CMP or whatever you want to call it..... are of a very high wing loading which makes for a poor 3D model. Do a search on CMP.

IM RESEARCHING THE 140 YAK AND IT SEEMS TO BE JUST LIKE EXTREME FLIGHT YAK 68 BUT BIGGER AND CHEAPER.

From http://www.willhobby.com/product/plane/ne8.asp

Wingspan: 70.8 in/1800 mm

Flying Weight: 4800 - 5000g

Engine Size: 2c 1.06~1.08 4c 1.20~1.40 (Not Included)

Radio: 4 channels (Not Included)

Servos: 6 standard servos (Not Included)
They are advertising a flying weight of 11 pounds with a 71" wing span. Do you think it will come in at 11 pounds?

The rear stabs look low on this Yak?


If you want a good flying Yak in this size range get the QQ 73" or hold of for the E.F. 73" that is rumored to be out this summer.

I'm assemblying now.
I weighted each major part: in grams
Fuse 955
R-Wing 404
L-Wing 391
Hatch 102
Cowl 269
Elevators 184
Rudder 76
LandingG 235
Motor Mount 70
==================
Total 2686

Looks like finishing weight will be 4.4Kg (9.7lb) with YS140 & Slimline Pitts muffler. I didn't weigh wheel pants.
Quality of the plane looks pretty good, but hardware comes with are cheapy.

I'm having problem with mounting motor. Book is not that great. Book is telling me 165mm from fire wall (not engine box) to prop washer, but that leaves very short engine.
If I do 165mm from back of motor mount, the motor mount is too short to have 4 bolts for engine.
I think I can do 160mm. Can somebody measure what the distance from prop drive washer to back of engine mount?

Thanks.
