this is my first bipe so forgive the dumb question..Are both wings suppose to be angled up for lift. or they suppose to be level? the manual for this plane kinda sucks.
another note im powering it with a 120 4 stroke. this a good combo or should i move up to a 140?

I don't have this particular model so....

Biplanes can have either minor amounts of incidence or zero incidence on the wings.

Typically the upper wing has slightly less incidence than the lower one, though you may find BiPlanes where the reverse is true.

The variance may be 1 degree or less to help the plane's stall characterisitcs.

I have a 56" 1.20 Ultimate Biplane that is powered by an O.S. 1.20 FS III Pumped engine. While the performance is very scale like, if I had to do it over I would probably go with a larger engine, say a 1.80 or so for better vertical performance.

My plane has an AUW of about 11-12lbs.

I set my ASM Pitts up as it came. That is the wing saddle set the low-wing incidence and I simply bolted down the top-wing. The plane is a fast and great flyer on a 1.40 engine. I currently run the ST 2300 in one, but will soon be putting the Mvvs 1.60 gasser in another.
