Hi,

I have been picking up various books on Air Racing so that I can build some Midget Racing planes. This involves the scaling up of the 3 view drawings.

Often there is a scale on the drawing and I start by focusing on that portion when I scale up the drawing on the computer. The issue that I am finding is that the "Scale" ruler on the 3 view is usually not accruate. Some are close and others are not. (Some drawings have the WS and L numbers on them but the ones I have do not....so this is all I have to go by.)

What I have found to be rarely accurate is the published length of the aircraft. These always work out to be shorter than what the "sources" say this number is. Often the Wingspans listed are the same between sources but the the overall length often differs.  One to 1.5 feet is alot on these small planes.

SO FAR I just use the Wingspan number for scaling the drawing. This appears to be a good practice.

What I would like to do before I start making saw dust is compare numbers on the actual 1-1 aircraft. I am sure that all of you have libraries of aircraft books (I just started mine... 2 books) and could reply with the numbers you see published in your resource info.  

I am looking for the Wingspan and Length on the following planes.

1)   Shoestring (Original plane)
           a.   WS 19
           b.   Length 17 8

2)   Lil Mike
           a.   WS 17 + ?
           b.   Length ?

3)   Cosmic Wind (Original low wing version on the 1st 3 planes, Minnow etc)
           a.   WS 18 11
           b.   Length 17

4)   Ole Tiger
           a.   WS 14 1
           b.   Length 15 OR 168 OR 17 2  (I think 15 is probably accurate)

5)   Buster  ?

6)   Bonzo  ?

Thanks for the help and sharing of information!
Mark

Hi Mark. I have four referencs for air racing. The two with the info you need are:1. The Golden "Age Of Air Racing (pre 1940) by the EAA and 2. The Air Racer, by Charles A. Mendenhall. (best and most complete info for modelers)

First there were/are two Bonzos. The first, the D-12 of 1934: WS;20'  OAL; 20'.(1934-35).  Then in 1937-39 the dimensions became; WS;17' 2" OAL;22' 2".

The later Bonzo of 1947-49. WS; 15' 4" OAL;19'.

Shoestring;1949, WS;19' OAL;17' 9". ( a later spinner change brought the OAL down to 17' 6")

Lil Mike; WS;17' 6"; OAL;14' 11"

Cosmic Wind; (includes Minnow, Little Toni, Ballerina);WS; 19' 6"; OAL;15'.

Ole Tiger; (Little Gem); WS 14' 1"; OAL; 16' 8".

Buster; WS;16'; OAL; 19'.

Hope this is of help.  Ty M. Hoff

Mark, Goodyear & Firmuls One Air Racing 19471967 Volume One and Goodyear & Firmuls One Air Racing 19671995 Volume One Two written by Robert S Hirsch are excellent resources for these racers as well.

Capt. Hirsch is an aero-historian. He has published several books, including a 2 volume set on Formula I. He also offers scale 3-views of most-if-not-all of the Formula I planes. Very reasonably priced, I should add.

Hi Geoff. Do you have these two books. If so, do they confirm the dimensions I posted? Coffee
