Maxun,

The color on my plane is flame red ultracoat. The 33% won't be much more expensive to build than the 30%.
The difference is mainly two exra servos, a slightly more expensive engine and a slightly more expensive airframe.
So if you are willing to spend ~$400 more, I would go with the 33%.

Greg

Greg, hows the build going, any surprises so ? Quality and fit still up to par? I was wondering how the horizontal stabilizers are secured to the fus. Same as the 37.5%?

No suprises so far. Everything is pretty straightforward as far as the assembly goes.
Matter of fact, I haven't been using a manual. Construction is light and top notch with
excellent fit of the parts. The stab mounting is straightfoward. Just cut the ultracoat
from the screw sockets and mount onto the wing tube with the incluced screws and
washers. Ultracoat also needs to be cut from a secondary hole in front of the wing tube
for the servo leads. Securing the servo inside the stab is a little tricky, but not bad.

For those using cans, the exit for the can exhausts can be seen in this photograph.
Just cut the ultracoat from the rectangular area.

One servo on the rudder should be fine as long as you stick with something like the JR 8611a or Hitech 5955
which are both metal gear, high torque servos. Not sure what the equivalent futaba servo would be. I am using
the 8611a on all control surfaces.

S9152 maybe ? it's a little bigger then standard servo but use bigger gears, Chief aircraft recommend this for the rudder of the 35% yak.
