The Honda RA272 was a formula racing car that won the Mexican Grand Prix in 1965 which is driven by Richie Ginther which making it be the first Japanese racing car winning the grand prix. After building my first completed Formula racing car, the Tamiya Honda MP4/4, I decided to build another formula racing car and it is RA272. I started this project in mid of October and finished it in 2 weeks time.

Detail up

Under the limit of information in hand for the RA272, I decided to opening the front hose, exposing the front bulkhead and also the engine as well.


Firstly, I have the nose cone and the chassis to sprayed with Tamiya White Primer and followed by Finishers Ivory White which is specialized for racing car at 60s. After decals on, I have them sprayed with Finishers GP2 clear coat.


I have used the Sakatsu parts in order to reproduce the connector for jointing oil lines and I have used 0.4mm dia. fishing lines for the oil lines. Also, I have painted those oil lines by using Gunze clear yellow and then erased some of the clear yellow paint on the lines by a dipping little thinner so as to simulate the uneven distribution of the oil in the pipes. I have also include the spark plugs in the engine and the wiring ends up at the connector which locate at the bottom part of the engine. For the velocity stacks on the engine top, they are Sakatsu items as well.


The pipe wall of the kit exhaust is a bit thicker so I have used the No.4 copper pipes by Wave to replace them.

Front bulkhead

The original oil cover was replaced by Sakatsu item and I have added the pipeline by using 0.3mm aluninimum string and covered with thermal-shrink material. Those AN fitting were by Sakatsu item as well.


Some detailing like the hose near the head rest area was represented by 0.3mm clear hose by Sakatsu. Also, there is a battery under the seat as well


This is one of the Tamiya formula racing car in 60s and personally, I really enjoy building it. Here are the pictures for the finished model and I hope you will be enjoy.
