About those RIKO motors:
This chart is based on a RIKO ad
in Model Cars magazine, Jan 1968.
We've seen a number of motors on ebay
being called RIKO motors from England, so I asked Graham about it. He says:
"RIKO stands for the name of the big UK hobby importer, RIchard KOhnstam.
As for the RIKO Rikochet motor, it was actually made by Hitachi, and was very popular
on the club scene over here in the 60s. I have both a MKI and a MKII. The differences
were that the MKI had a 5/64 shaft and a black end bell, while the MKII had a 3/32 shaft
and a white end bell."
"All RIKO MKI motors were considered to be better than the MKIIs,
as they had stonger magnets. The Rikochet MKI, being the stongest of all the range,
was the poor man's arco. Everyone used to use them in their hot motors over here.
A common mix was to use the RIKO Flash MKII armature with Rikochet MKI magnets.
This was a great combination and gave a power output close to the
16Ds of today."
