These sizes are very popular in Japan, because they drive mostly smaller cars as in the USA.

Looks like the Bi Side is making progress. BJ has posted some pics of the painted fuselage. Here's a pic

Our company demo plane is shipping next week, if you are going to Muncie, look for it there and flying and available for customer demo flights.

Yes, it really looks nice.

It looks like he made several modifications from his original prototype. I notice that the vertical fin and rudder have changed (he added more area to the rudder and made the vertical fin taller), it looks like the wings are different (perhaps smaller/less area) and I think the wings have moved forward slightly.

Wow! If that flies half as good as that looks, it will be pretty popular!

The vent behind the wing is also removed....he mention on his blog that the wing would be thicker....

I like the Orange and white on the bottom. The silver might take some dimension away at 150-170 meters and make it look funny in reference to the lines of the airframe. I personally would ask for the silver to be painted orange. Might add some definition to the outline of the airframe,..That's just me.

It still looks kool!

Plane looks great. Definitely agree on the silver. Maybe red would be better or something else. At least to me anyway. Definitely next plane on my list for purchase.

AmericanSpectre505

Yea,..red would work good too. I have been eye balling this plane and waiting for it's release. I have some other irons in the fire at the moment. I doubt we will see one at the NATS this year, who knows.


I am going back to my old ways "if I can't fly one, I ain't buying one"

I second the motion, change the silver for red

We are epecting these by the end of the week.
The first 3 we have coming in are priced slightly higher due to the extra frieht costs to get some air frieghted here versus the slow boat from China approach.
We have them up for sale now.

Thanks and see you at the Mationals. Mike Mueller

Any idea when the first shipment from the slow boat will get here

Such horrible dilemas.. Do I buy a Biside for 2014, or build a new race bike?

mups53

My Feedback: (41)

That depends on the response we get on the 4 we have coming in anyday. I'm thinking it'll be here by tomorrow. After that we can decide on a larger shipment. Based on normal turnaround it'll be September something.

Doug you know what I would advise. Mike

Hi Doug,
Would you mind sharing your views on the double (triple) taper wing on this and the Episode.
I'd be interested to hear as I'm sure would others.

The first shippment of the BiSides has landed. I have 3 andChris has one. We will be showing pictures when we get a chance to look at it. Mike

So basically the multi-taper wing is just a simpler construction method trying to approximate an Eliptical pressure distribution, which (generally) gives you reduced induced drag, making the airplane retain more energy through things like snap rolls, as well as when making pitch changes, either positive or negative. Additionally, as the chord gets smaller towards the tip, the wingtip itself generates less vortices, which again improves efficiency. The end result for pattern airplanes, is less power is required. For electrics, this can be a big plus in that you can get through a sequence using less battery. I think this is a big reason why you see BJ making comments that the Biside requires much less power than he expected. The induced drag created by the airplane in pitch changes is much lower than he expected as a result of the planform.

The big problem I see with these wing designs is keeping them stiff enough to retain their shape, and especially at the wingtip, ensuring you don't wind up with any twist, both statically (as built), and aerodynamically (under load). The static form is easy enough to verify, but aerodynamic, not so much.

Please note, I'm NOT suggesting the BJ Craft airplanes are having any aerodynamic twisting issues.

Hi Doug,
Thanks - interesting !!
The twisting under load thing is also interesting and is an issue for a lot of these F3A bipes.
There is very little section taper in a lot of these and they twist very easily.
I have been modifying the strut mounts on mine ; 1. to set the tips better and 2. to give more hold on the set.
I think there is more that can be done with strut design in this regard.

Our demo plane has arrived and will be in Muncie... working hard now on getting it built in time.

Looking good, I hope to see some pics from your build Chris. Also what size Futaba servos will fit in the tail?

Wow, too bad I just wrecked my plane budget for next year.
