It has 2 - elv. servos in the rear and a pull / pull rudder ( as seen in pic. ) I had no problems setting it up at all, very easy. I have 9001's on the elv. ( plenty ) a 5945 dig. MG on the rudder ( plenty ) but I started out with 9202's on the ail. and stripped one in short order. I then put in 5625's which made an awesome difference in control. This was the first time I pulled analog servos and replaced them with digitals, I'll never buy analog servos again.

IMHO the YS 140 would be perfect. You have to mount the engine upright [:'(] or inverted and the YS works well inverted. I have a 140 in a pattern plane and I might just try it next summer in the BN120. You can only squeeze in a 16 oz. tank but that should be OK with some throttle management.

The plane should come out at 11 - 11.5 with a YS or OS. Mine is 13.25 with the gasser and it is just too much although the airframe carries it well and even at that weight this plane can be flown at about 5 mph without stalling. KE is incredible using about 25% rudder and no elv. or ail. correction needed. If there is any problem with this plane it would be that it floats forever and requires great precision in landing if you have a small strip ( ours is only 350' paved ) but it might as well be a postage stamp with this plane. It could be from the extra weight I carry but I have an 18" prop and an engine that will idle all day at 1500 rpm's. I'm used to it since I also fly pattern planes but I prefer "draggy" sport planes, like bipes . It's not a big problem, just something to keep in mind.

And oh yeah, THIS IS NOT A 3D MONSTER and don't buy it for that ................................. Good Luck [sm=wink.gif][sm=thumbup.gif]
