Model Merchant Inc.
Anyone know much about the so called F-15 model made by Model Merchant Inc. and is it worth building and flying. Apparently the person selling it has the whole kit. Here's a pic of one of the pages.

RE: Model Merchant Inc.
The manufacturer put a flyer for a pattern ship in the box with the ducted fan jet. If you bought one 'Model Merchant' kit, you might buy another one too. It's marketing.
I noticed that the flyer mentions a gear reduction drive for a 2-stroke Speed .61. Is that a good alternative to a 4-stroke?

RE: Model Merchant Inc.
the person who took the pictures don't have any knowledge of the kits. I believe the kit had belong to a family member that passed away. I know they had two other kits they were also selling but they wanted $350 for all three.

Tom,
I believe that pattern kit pre-dates the wide spread availability of 4-stroke RC engines. It is actually a .90-.120 2-stroke size model but for some reason, gearing a .60 was the thing to do for some brief period of time back in history...
Clearly a tail dragger spinning 18-20" props!
Cheers, David.

RE: Model Merchant Inc.
I believe the plane pictured is a ducted fan model designed by Duane Johnson of St. Louis, MO. Model Merchant built these kits. Model Merchant later became Aero Telemundo. I have several of their kits - 2 Martin Baker MB-5s and the only pattern plane (as far as I know) known as the Double Eagle. Their planes were mostly ARCs (almost ready to cover). The workmanship was extremely good. Hope this has been some help.

RE: Model Merchant Inc.
Thanks for the info. Maybe I'll stop by this persons house and do some more investigating on this plane. Hopefully she would be nice and give me deal.

Tom - geared engines are very noisy. The high pitched prop whine was eliminated, but the gear noise was impressive at a slightly lower pitch. Too much noise for FAI requirments and no way to eliminate it. The engine noise was also a problem as the engines were still turning high rpms. OS and Webra are the only manufacturers that produced geared engines that I'm aware of. Dean Koger used an external belt drive reduction system on his Vortex design which he campaigned quite successsfully, but that never caught on either except for the TOC airplanes.
