I was amazed to see on your web site several chassis
that I had built or modified in the late 80s/early 90s -
I refer to the John Young collection. I can tell you something about each one
of these four chassis. I'm just curious about how they ended up in John's hands.
These chassis were built for former club member Clive Griffths, who I lost touch with
several years ago, and who used to race with me at Timaru Model Car Club in East Kent.
Chassis 4 is one purchased from Missile Products and advertised originally as a Mac chassis.
I did the front axle mod and also the rear axle strengthening. If I remember rightly,
the underside of the chassis has a fancy pattern on it.
Chassis 3 was a scratch built by me probably about 10 years ago. This configuration
was our standard club formula at the time, and I think probably has a Mura Wasp motor.
Unfortunately the chassis were not particularly strong, as any impact at the front
would bend the 16 g main rails or break/weaken the joints with brass plates
at the front and rear. It was then difficult to get enough heat into the joint
to make a decent repair.
Chassis 2 is obviously an inline F1 and was built to BSCRA regs of the time.
The motor features soft cobalt magnets which were very popular in the late 80s
as it meant smaller motors could be used. The can for this one is based on the
Mabuchi MRRC 111 motor with the endbell a proper Mura one turned down to fit.
These were marketed at the time by Dave Harvey at 101 Products. Probably a
Mura Wasp arm again. There are similar F1s in the Readers
Gallery numbers 66 and 67 posted by John Secchi.
Chassis 1 looks like my handiwork again, although I have to say I don't
remember building it! Again it has the 'mini motor' popular at the time,
but this can is one of Dave Harvey's proprietary ones marketed under
the 'Infinity' label. The cans were stronger, thicker and straighter
than the 111s mentioned above. If I did build it, it probably has a
Mura Group 20 or Cheetah arm. The chassis design is based on one pioneered
by multiple ECRA champion Steve Walker.
