Hi Bob,

The Bosta was published in October 73 AAM magazine. I still have my copy

Here is the one remaining of the many I built. Full size but for a Rossi15.
Also have one with a G21 on it, but I did not build that one.

Happy New Year,


Pat MacKenzie

Cool airplane Pat. I purchased one of those "15" Bosta's and am about finished with it. Should be a 1/2a model by the size, but cute none the less. Would you make copies of that article and mail, or email it to me? Do you have any other combat articles? I need all I can get

I know I have a few, I can dig through magazines and see what I have.
Should even have some of the British designs in old Aeromodellers.

This is a full size Bosta though, not a .15 size.
Even full size is tiny by modern F2D standards
42" span, 10" root chord works out to 330 squares.

The Bosta is one of my favorites from the 60's-70's and that one's beautiful. Would it be possible to reduce the area of the center sheeting by only having balsa supporting the push rod outlet and to provide more area for your shrink covering around your fuel cell hole?

The Bosta borrows a lot of its structure from the Nemesis. It too had the wide centre sheeting.
The centre ribs are only 1/8" balsa so I think the sheeting actually provides a lot of the strength holding the tail on the plane, even with the mono-boom like mine.
(In a lot of ways the Bosta is basically a Nemesis with an elliptical planform. Similar structure and same airfoil)

Hard to imagine we used to run these on .35s. They seem so flimsy compared to a modern F2D model.

I built single boom Nemesis's with a solid center rib. The bell crank platform was slotted into the center rib. Like The Super Voo Doo, I used no center sheeting except for a very small area supporting the push rod outlet. I used golf tubes and FF launch rubber for fuel cells. Built for sport flying, these planes had a long life. The only problem was that after 3 or 4 gallons of fuel, the fuel cell hole took a beating from the exiting fule line at 115+ MPH, raised the shrink coating and allowed fuel to enter the air frame. So my question is, how can the fuel cell hole be reinforced to allow hours of air time on a primo design like a Bosta or a Nemesis?

The Bosta was at the Nats in '72. Can't remember the guy that flew it, or if he was also the designer... but I remember talking to him, the name of the airplane, and what appeared to be a difficult-to-construct-for-combat airplane. The Bosta that I saw was a twin boom. The mono-boom craze didn't hit until a year or so later.

Yes, I remember flying with The Sky Burners outside of Los Angeles in 1975. The buzz was all about the efficacy of single boomers. Soon many were redesigning the best designs of the day into single boomers.

The SweetSweep kit came out in the mid 1950s. I think the Grogan family put them out. I remember seeing an ad in a magazine, and discussed the kit with a fellow I met briefly early in 1958. I think the Bosta was designed by Bob Burch from Chicago. The Manx Cat was kitted by Consolidated.

Bosta was by designed by Neal White. There is a picture of Burch in the magazine article as part of "Team Bosta", so he certainly flew them.

I flew Bob at the Nats this year in F2D

I didnt even think of that. I need to find some old mags and look for the adds for these kits. That will narrow down the dates quite a bit.

Bob,

I have the Flying Models article of the winder I can send your way, it talks alot of the 1967 Nats and such, so I'd guess the Flying Models article would have been early 1968. My copies don't show what issue of Flying Models it came out of

George

PM me with email and I'll send it to you...

Have you checked Barry Baxter's Plan Page? A lot of the plan descriptions include the intro date. See: http://www.controllineplans.com/frameset2.htm
