About me

image20

My name is Jim Oosterhuis, owner and sole operator of Giant Scale Twins.   


From 1993 to 2003, I was working as an Electrical Engineer in California.  It was there that I met Charlie and Bev of Modaire Industries at an RC air-show in 1998, where I purchased a P-51H kit from them after seeing it fly.  Charlie, Bev and I became very good friends, and not long after, we started a new business together called Modaire Hobbies located in Manteca, California.  


In 2003, I moved home to Iowa to the family grain farm, where I live and work today.  


In 2006,  I purchased all of Modaire Industries' molds and tooling  from Bev and Charlie, and started doing business as Giant Scale Twins.   My company is a reincarnation of Modaire Industries, producers of the legendary AeroCommander, F7F Tigercat,   F-82 Twin Mustang and P-51H Mustang; 

Unique and quality twin engine kits that Modaire Industries became very well known for.


My Schedule:

I farm with my parents during the summer months on the family grain farm.  However, in the winter months when the snow is flying, I build airplane kits as Giant Scale Twins.  


That being said, please be patient with me, especially during the summer months!  If I don't answer the phone, please send an email (info@giantscaletwins.com) and I'll get back to you as soon as possible.   


And, as if farming and kit building doesn't keep me busy enough, I also build and fly full scale.  In 2006, after 1100 hours of build time, I finally finished building a Van's RV-8 shown in the photo above.  

Currently, I'm building another airplane, a Zenith CH-750 STOL.  


About the kits:

The kits are unchanged structurally from the designs and Charlie shipped, and I promise they will be of the same high quality construction.  However, I continue to make improvements where I can to make these easier to build or increase strength, etc., and offer more accessories as I can develop them.  


Every aspect of these kits is hand-made in the USA.  The polyester fiberglass parts are hand-laid to be kept as light as possible without sacrificing strength.  Fiberglass & carbon fiber tape and resin are used to reinforce large fuselage sections.  Wings are hand-cut polystyrene foam, inlaid with aircraft-grade plywood spars and hardwood stiffeners.  Leading and trailing edges and wingtips are balsa stock.  Wings are sheeted with cabinet grade 1/64th Birch plywood (included) using epoxy (I recommend West Systems).  Wings can either be covered with Monocote™ at finish, or laminated with 3/4 oz. fiberglass and epoxy resin  and painted.  Either  technique provides for for fast construction, a beautiful finish and amazing strength.  Included with all kits are:  Fiberglass fuselage(s) and cowls, clear formed canopies / windows; wing joiner hardware (except for the P-51H which has a one-piece wing);  all structural wood and wing skins; detailed assembly manual.


Thanks for your interest!
