Tim that's excellent!!

did you resize it or went with the original plans?
normally it should balance just fine with the battery and the other equipment placed between the inner struts. i wanted to concentrate the battery/equipment relatively far forward (better cooling by propwash and less damage done to the structure if you happen to crash it).


If you add the linked ailerons and maybe try to reduce weight/increase power in the future you surely will have a lot more fun.

Do you have any pics to share with us?

Chara,
I built it to the plans size. It flies great with the 1500 battery so I'm not too worried about it. The battery sits just forward of the inboard strut on the horizontal stiffener. I probably changed the balance a little by replacing the over wing stiffeners with balsa. It's also possible that the motor and mount you used is a little heavier than the CD motor and bamboo skewers too. I was thinking of using the Hobby Lobby Esskay on it. It's about 1/2oz heavier than the CD motor and would put it up at the 3d wattage in your plans.

I'll post some pics a little later today. I am looking forward to getting it painted (probably a couple weeks from now). We were having a difficult time with orientation on the BiPie without some sort of paint scheme. BluCor against a nice blue sky can be tough.

BTW, how is the name pronounced? My daughter says it's "Bippy" and I say "By-Pie".

I'm thinking of building one for a lazy afternoon flier and have a bunch of CD motors that need winding.

Mike,

I just used the GBv standard kit. It uses 26 gage wire in the wye configuration. I just followed their instructions to wind it. I didn't measure the current with the 8x4 prop, but the 7x4 prop and 2S battery was about 6A. It's probably running about 7-7.5A. I am using the Cool Runnings 10A esc. I have three of them and had good success.

Tim,

I hope you're going to have a lot of fun with Bipie (pronounced like "By" - "pee", was not so sure how it should be spelled in english ).

Looking forward to your pics!

Hehehe, english/american spelling & pronounciation is a real adventure! It's still being evolved! You'd think after 200+ years we'd settle on something!

I guess I've been pronouncing it wrong, as well Let's see, Buy-pea, By-pee, Bi-P, Bie-pey I'm sure there's more! God knows how the kids would spell it, thanks to phonics and SMS (text messaging) and I'm sure it'd be different in real English. Are the Brit's still evolving the language on their side of the pond? How about 'down under'??? What a mess.

Hey everyone, I downloaded the plans last night and already im a about an hour away from completion. great plane chara!

So far the the wings are built from 5mm RCF foam and the rest of standard 6mm depron. I'm also planning on useing the fiegao brussless motor/ 3s lipo combo for a power system.

I'll tell you how the flights go when its finished

Oh, the printer settings on my computer butchered some of the edges for the tail and rather than fussing with the computer I decided to simply cut it strait for simplicity.

But, yeah I now have all of the elctronics and power system installed for a total weight of 6.8 oz. Hopefully the maiden will be soon!

Bobsean,

Tell me more about the RCFoam. I started a thread asking for info on this stuff. Do you have to bake this stuff in an oven or can you just go ahead , cut and build a profile plane just like using depron or fff. How does it compare to the depron other than being 5mm vs. 6mm. BTW, That Bipie looks sweet I too love the two-tone foam. Yours is the first plane I have seen with the RCFoam. Very cool. Congrats.
