Global Ultimate 40
Just wondering if the Global Ultimate Biplane 40 is a good airplane. Just want to know any information good or bad before I consider buying one. Thanks

Great!
As far as ARFs go, I think this is a good one...and it's on sale at a more reasonable price right now ($170 at HobbyPeople.net).
Mine went together without any real glitches...it was a quick assembly. The covering and craftsmanship was very good. I was really impressed with the strength of the fire-wall area.
I recommend really strenghtening the landing gear mount...mine and a friends both popped out without a lot of stress. I replaced their wire push-rods with 2/56 threaded ones and matching clevises. Everything else is stock. I recommend cutting the sides of the servo tray out so you can reach the metal cabane adjustment screws with needle nose pliars after assembly is complete.
I have a YS .63 on it. I think it's perfect. Will hover (up high) though it won't pull out of the hover. This plane is smooth, but can be snappy. I have 2 oz of lead on the tail.
If you want a quick bipe, this is a good one.

I have a Saito 100 in mine. Moved the servo plate
as far aft as possible. Also moved the battery aft
to balance without adding extra weight. Have a 3-bladed MA 12x8 prop with a Tru-Turn spinner. As far as the landing gear, I just order a new one from TNT. This will do several things for me. 1. I increased the length for ground clearance. 2. Reposition the bolt holes so (2)holes are forward and (1) back. Instead of all (3) in line which will pull the gear back. So far, This is a fun plane. There seems to be no bad habits. I have unlimited vertical. I have not tried to hover yet, but since I'm flying at 1/2 throttle or less, I should be able to pull out. Word of caution: Check, check, then triple check the incidence of the two wings. The screws & bolts that hold the cabanes do losen and allow the wing incident to change. Good luck with yours. I'm having fun with mine.

Good flying little plane. I prefer larger planes, but this is my little beater plane. 
I have a Saito 91 in mine running a 13x6MA and plan to put a 14x6APC prop on it. That should let it hover at about 1.2 throttle.
I have micro servos in the tail 2 on the elev, 1 on rudder. This kept me from having to add any weight at all. I will sson replace the heavy throttle servo with a micro. Also added 2 micro servos in the ailerons, just opened up the hole a little bit.
The one thing I would do with this plane, is add flying wires on the vert and horz stab. They flex way to much and if you use the larger engines, may find them snapping on you. It will fly much better with them on.
Even with an OS 46, this should be a hot little plane.
