Hirosaka edition Kyosho Stallion

Hirosaka edition Kyosho Stallion

We have shown you the work done by Masaaki Hirosaka on the Kyosho Stallion before in which he has completely modified it to the point that it is hardly recognisable. Today on his site he has announced that his version of the car will be shown at this weeks Shizuoka Hobby show, and judging by the very neat and final looking car in the picture above we presume it is getting ready to be sold. Also mentioned on his site is the fact that he will be selling, to order, pre built versions of the standard Kyosho Stallion TF-5, so if you ever wanted your car built by a World Champions mechanic, now is your chance.

Hirosaka prototype Kyosho Stallion TF-5

Hirosaka prototype Kyosho Stallion TF-5

We’ve written briefly about Masaaki Hirosaka, father of multiple World Champion Masami and top RC mechanic, before and the fact that he makes some pretty cool well thought out products. Well here is his take on the Kyosho Stallion TF-5 which takes a different approach to that used by Josh Cyrul who’s car we saw at the Snowbirds. As you can see from the pictures, the batteries have been set further back than normal and where the top deck connects with the front bulk head is pretty unique too, although i cant tell you exactly why. Also note that the rear body mount is bolted directly to the bulkhead which means the downforce generated by the body shell is pushed straight down onto the chassis, its mounting position also protecting it from crashes.

Masaaki has also created patent pending one touch total length adjustment shock absorbers. I cant tell how they work either but i have included pictures of them below.
