About this Plan

Baby Bi. Radio controlled sport model for .40 power.

Quote: "This little 36in span .40 powered stagger bipe is easy to construct and will do any maneuver you can dream up. It's a must for your hangar of models. By Fritz Schuetzeberg .

The 'Baby Bi' came about after nineteen years of looking for a small, high powered, easy to build, roomy airplane. If you study the lines, you may see that it's a cross between a Nesmith Cougar and a Staggerwing Beech with a little Knight Twister thrown in. The Baby Bi is 41-1/2in long, 36in wide with a 12 oz tank, but you can get both hands and a screwdriver, along with a radio unit, in the radio box. To make it big, it has two 8" x 36" wings giving the .35 to .40 engine 576 square inches to pull around at only 51/2 lbs.

What does all this information give you'? Well, with a good .40 engine and big wheels. she will jump off the ground, do any manuever you can dream up. Then she will slow down fast with the two wings and large fuselage and, with the constant chord wings, she will land at a walking pace. Another good bit of information is that I fly on a three acre field with wires all around and haul the Baby Bi in my Volkswagen convertible.

To fly the Baby Bi, point her into the wind, open the throttle, add right rudder to point the nose and let her lift on her own. As she comes up, roll just a bit left and climb out. Try 5 or 6 stalls and note the slow break. Bring her around on final with the nose down. Flare and watch that slow stall. After you get use to the fast slow down, you can do some of the smoothest nose up, drag in, full stall landings you have ever seen.

Well now, look at the pictures, look at the plans, and notice the easy build and clean lines. if you like what you see and have about 40 hours of free time, let's proceed.

Construction. The Baby Bi is designed to make the best use of materials at the best price. Follow the cutting list to the letter and you won't have much scrap. See the bill of material when purchasing parts. Cut all parts by the list at this time..."

Very poor flight characteristics, we do not recommend to build [see model photo & morepics 004-009].

Care to tell us more? What happened? Was the balance OK?

I built one about 15 years ago and it flew great. It was powered by a 40 FP. A friend tried it and talked me into selling it to him.

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
