Title: BOSTA Plans
Post by: Pat Johnston on December 14, 2011, 06:53:30 AM
The BOSTA is my vote for the most beautiful fast combat machine ever.  I just finished drawing ACAD plans for it from a set of originals that Peter Martin supplied to me.  Many thanks for that, Pete!
Here is the PDF file so all can view it.
In using the ACAD /"Ellipse" function for the front and back parts of the wing planform came out to within about a 64th of an inch of perfect.  Whoever drew the original plans was a master.  They got the mathematical components of an ellipse just about perfect.
We now have the BOSTA enshrined digitally for all to have.

That wing needs a small Spitfire fuselage  :!  VD~  ;D

... or it could go into a small scale approximation of Joe Adamusko's Stuntress ...  :##

Yes, I always thought that was one beautiful combat plane.   The one in my picture was built from a hand cut kit from Hawaii.   30 inch span with Fox .15 Schnuerle on suction.   Very fast and touchy on the one flight I have on it.   Have made the control horn taller and plan on using FAI combat handle next flight.    H^^

Doc,
I think that the Bosta with all contest balsa and a new hot FAI Combat 15 motor would be very good in the FAI class.  It is a good size for a hot 15.  For sport flying, a newer ball bearing 25 could be a blast, or even an ST C35.

Yes the full size Bosta would make for a very competitive FAI plane if it wasn't for all the peices in construction.   H^^

Several years ago, I re-drew the original, pre-magazine version of the Bosta plans directly from Neal White's original drawing which was made when he was at  Purdue.  I'll ask Neal if it's OK for me to put them up here for everyone's use.  I also re-drew Howard's magazine version of the Nemesis II plans (there are at LEAST 3 different versions).  I'll ask him too.

Attached is a CAD version of the pre-magazine Bosta plans as authorized by Neal White.  Enjoy.

Thank you, guys! I've been wanting to build these 2 but could not find a reference for the plans of the Bosta. Had one in the early 70's and loved it. But did not want to build 20 of them as the wing and structure were a lot of work for a combat plane. One of the beautiful designs...

To All:  NOBODY knows more about the "BOSTA" than Bob Burch (Chicago) who flew them for many years.  He knows every in/out that goes on with this design.                               Bill Allen

I'll see if I can find the original magazine article and re-type it for posting here like I did with the Nemesis II article.  Does anyone happen to know what issue of AAM it was in?  I've got all the back issues.

Gary's are accurate.  Others may not be.

I THINK someone did that - used the Bosta wing as the basis of a Seafire profile Carrier model.  However it would make a GREAT sport-stunt model...
