Super slow Stunter

[EddyR]

Has anyone ever seen this plane. I believe it was a 1960's design published in AeroModler 1968. It reads "Incredible slow but sure Stunter" by Walter Bagalini.
 Note the 20 degrees engine offset. It looks like the  European design from those years.

Looks like a semi scale Ziln.

Hi Ed,

The I-Baga-14 is in Tom Morris's Anthology of Classic Airplanes.  I have always thought it looked quite interesting and was worth modeling.

Jim      I think I copied the print from Tom Morris's book many years ago. I just did a Google search and found he flew this model at the 1966 world internats. Here is a picture of a earlier version with a date of 1965. It may be older. This one does not have tapered flaps. This one has a "12" on the side and the print has a "14" on it. So the print must be a later version.

So is it primarily the thick airfoil that makes the plane "slow"?

Ed --

Ver-r-ry Interesting! Twenty degrees! Wow, what is the offset in a Bi-Slob?

Sounds like this is meant to really fly a pattern, not just dink around like a Bi-Slob. Any idea of speed or lap times?

Any other noticeable slow flight features other than the engine offset?

A lot of early French designs had this sort of offset. I've been looking for one to suit a Micron 29 I'd like to fly.

I prefer to fly fairly fast, as I think this gives the judges less time to see my mistakes.

When you try to fly slower than the minimum needed to keep the lines properly tight engine offset is a good way to add more line tension.  It's really the only way.  The engine offset translates some of the engine power into line tension.  The downside is the large offset may translate into some other trim problems.

If you type Walters name in Google you will get a report on the 1966 World Champs and in that article it mentions that he used a ST/35 for power placing 10 in the first round. I found out long ago that no motor offset and a straight rudder makes trimming much less of a problem. I would not recommend this model for competition but for a fun project or maybe just to have something different in classic it might be a a blast to fly.
  As a side note back in 1957 I built a Nobler with a straight wing. All stick construction with no wing planking. It had over 600 sq" and a very old Fox.35 with just a little motor offset. It flew very slow  with the poor old Fox screaming on 30% nitro. It was hard to believe a stunt plane could fly that slow. It only lasted a few weeks as I crashed it because of the very underpowered condition. For my level of flying at that time I thought it flew very good.

I like it.  Ever offer 'em something to drink a couple of flights before your own?  Hey, it works for me.  The secret ingredient comes in quarts, but you can't get it at just any medical supply outlet.  Fly fast and drug 'em.  Can't wait for these contest events to start paying cash.  Gotta figger out how them Nascar guys did it.
