Design Contest Ultimate Biplane Progress - Completed and flown!
Well, I finally got off my but and started on the Ultimate. So far I've got the cores sheeted. 3/4lb foam, 1/32" sheeting with polyurethane.
Going to buy the aileron stock, NiMH battery pack and a digital scale today. I'm trying to keep it light!

looking good! you did see my 25 size one, didn't you? it is not going to be near as slick as yours, though. the sheeted wings are smoooth!

Yeah, I saw your .25. It was modified from ACE Ultimate wasn't it? It sure looks a lot better than the ACE and is proabaly a lot lighter too. I had an ACE, which flew very well with a .25, but all the plywood... hoo boy! I've got a .90 sized bipe with less ply than that.

Real nice
are U using the same wings I bought from You
am a bipe lover and have a 061 and 074 norvels waiting for something like this
real planes have 2 wings if not always a round engine

They are exactly the same as the ones I sold you except the ACE wings are about 2.5 times heavier. If you built one using the cores you have and balsa instead of ply you could save a lot of weight.
You should be able to buy the plans from ACE. http://www.acehobby.com

that's right, now I remember that plane! yeah, the ply fuse was a brick, but I had to do some thinking to get rid of most while still keeping strut attach points. mine is LIGHT, but I need to weigh it so I can give you all a final figure. I know from weighing components that the fuse was over 2 oz. lighter than stock!
on the cap, I used 1/16" w/a 1/16" balsa doubler. most 1/2a overbuilt. For instance, my combat stuff uses undoubled 1/8" balsa sides w/ a glued on 3/16" hatch. I midaired my son's last saturday, knocked his tail off at about 100 feet. it went straight in. cracked the 1/4" luan firewall, but I made a new tail (elevator munched, and we couldn't find rudder) repaired the hole in the wing, and it's ready again. no damage to the fuselage! and mine was fine, except impact broke one side of aileron horn off servo; thank goodness for metal gears! I wondered why it landed out of trim...

I agree, not just ½A but most planes are overbuilt. I use 3/32 sides on my ½A stuff and usually don't use doublers. I also trye to use balsa for formers instead of ply.
Speaking of combat here's a picture of the results of a mid-air. The plane on the left is an un-sheeted pink foam wing with 1/4" balsa leading edge. The black plane, mine, has an ACE wing with d-tube and cap strip sheeting. The throttle wire was cut in the collision and my plane went straight in from about 150' like a dart. Still, I cut the other plane in half with my wing.

OUCH!
looks like a game of 1/2a TAG- !!!!!
cool, sheeting and caping foam wings is so easy and strong, I love it!

I'm trying to keep it light. So far so good but planes always seem to gain weight somwhere along the way.

What engine is going to pull this, and what do you plan to make the cowl out of??
By the way....WOW!!! It looks GREAT so far!!
What's next a 1/2A Bulldog? (HIN, HINT)

It'll have a Norvel .061 in it. If it wasn't for the contest displacement restriction I'd probably use a Norvel .074.
I might make a fibreglass cowl but I'll most likely vacuum form it out of high impact polystyrene. It will also have vacuum formed wheel pants and a canopy.

Hay Bipe Flyer..... SWEET biplane!!! I may have to get a set of plans for this one too.
I just got a set of your 1/2A Stick plans. They are nice plans. Vey clean, and the construction is SUPER LIGHT!!! I was pleased to see how light it will turn out.
Can't wait to see the end result of this Bipe project.
