This page attempts to address the issues of two of the rule change proposals put
forward for voting in January 2013 in a clear and unbiased manner to assist members
in their decisions.
B9 Rules E2.3.10 and H2.2.13 (production chassis hardening etc.) shall be deleted. NOTE In the proposer's opinion, it is impractical to enforce the existing rule.

The following is an extract from a report sent to the BSCRA Council in regard to using this motor for Class 4a Production Racing Produced and compiled by Andy Brown-Searle of AB Slotsport, the official UK Distributor for JK products;-
JK 3030 “Hawk Motor” this was launched as a competitor to the Proslot Euro, featuring
the same size can, albeit with a larger vent hole, ceramic magnets and a slightly
hotter wind than the original Proslot Euro. This motor may be disassembled the same
a conventional C can motor.
JK30306 “Hawk 6 Motor” this is the last version of the strippable Hawk. It has
Neodymium magnets and and endbell which has been redesigned for “USA” type commutators.
It also comes with a replacement set of motor brushes as the brushes in the 3030
Hawk, were to be frank, truly horrible.
Serious objections in regard to allowing HAWK 6 (30306) or Hawk (3030) into BSCRA
1) BSCRA has over many years now adopted the sealed FK type motor for use in Class
4a racing, it is clear, despite a few teething problems with earlier versions of
the Falcon motor, that this policy has been widely accepted and as a consequence
has led to the adoption of this type of motor in a wide range of applications as
a low cost and very even form of racing which in the novice class has provided a
vehicle for fixed price motors which cannot be “blueprinted” or otherwise enhanced.
2) Throughout this period of racing with the FK motors, novice racers ( which form
any kind of growth in our sport) and many others have found that that this form of
sealed motor racing has provided a cost controlled, low tech, and reasonably level
playing field in terms of a wide range of racing classes , not only in Novice production,
but also Falcon Pro, BSL and UKRRA racing.
3) We are, at this time in a period of serious financial recession and I firmly believe
that to open the novice (class 4a) racing to strippable motors will seriously harm
the sport by encouraging an “arms race” in regard to aftermarket services, product
and blueprinting. So much so that the cost to the racing of a motor would rise from
the present £9.95 per motor to around £45 + for a blueprinted motor.
4) Aftermarket versions of these motors are available from Koford, with aftermarket
USA type armatures available from Koford and Proslot and reworked Chinese armatures
available from Fast Ones, Alpha and many more.
The armature shafts in all versions of both the standard JK and Proslot motors are
NOT drill blank, so as a competitive motor there would also doubtless be a call for
the use of ballraces (or indeed aftermarket armatures).
The standard 3030 Hawk armature is not “tied or epoxied” and is therefore a “shoe
in” for dewinding and aftermarket tweeking of timing etc.
Combined with the interchange possibilities of magnets from Proslot, the original
JK ceramic magnets, the JK Neodymium magnets and even the easy (and it has to be
said the rather effective use of Falcon 7 magnets) in these motors, the Association
would be laying open a total minefield for scrutineers in terms of legality of armatures
and magnets, along with the interchange possibilities of at least 4 different endbells
from Proslot and JK, along with a black aluminium endbell which is now available.
Add to the above that USA armatures are also available for these motors from both
Proslot and Koford in G12 and “Open winds” down to 24 gauge.
5) As a distributor, it may be thought that I would welcome such a “commercial opportunity”
to “bleed dry” any racer in the Class 4A category, however, this is not the case.
As JK’s official UK distributor I am probably in a far better position to benefit
from any such rule change, however, I consider that any such move to a strippable
motor in the Class 4a category would irreparably damage the class in terms of racer
cost and participation and also lead to an almost unstoppable “blueprinting and tweeking
As a cost comparison to the present Falcon 7 and proposed other FK motors at retail
At raceway 81 we race the JK Hawk 6 (JK 30306) with a ballrace in the can and an
option to use the Proslot “Hawk” aftermarket armature.
The cost of this motor from new would be
Hawk 6 motor £13.25
Ballrace £ 5.00
Motor brushes £ 2.90
Proslot armature £22.50 (It would be highly unlikely that any “blueprinted JK 3030
armature would cost any less).
Total £43.65 minimum cost with no “blueprinting, rebalancing etc.
The racers at the club accept this cost as the chassis/motor combination is used
frequently in 2 different classes and it performs faster than a Falcon, even on the
“fixed shortest gear ratio” which is enforced @ 3.5:1 which ensures motor longevity.
Without this gear ratio “fix” in the rules these cars would without doubt (an after
testing) be as fast as good G12 motor.
Not I am sure the type of performance that we may wish to inflict on Novices and
definitely not with the scrutineering implications or the price.
“By 2.30pm on Friday the 9th., 14 Uber keen racers had already appeared for a bit
of practice and to settle in for the weekends fun. Friday evening consisted of a
1 ½ hour team race for open chassis, JK LMP bodies and a chance to try out the new
JK Hawk motor. The full results of this race are now consigned to the dustbin of
history (due to the computer dramas of Sunday Morning) but it did prove to be somewhat
amusing! Of the six teams that started, only 3 finished without loosing the will
to live (the others having blown up a selection of motors). Performance wise the
motors did show a good turn of speed with lap times between 4.1 and 4.3 seconds,
but some failed due to loose windings and rather interesting Smoke outs when they
let go. (Glad to say there will be an epoxied, tagged and rebalanced version of
this armature available in the next few weeks which will doubtless prove to have
sorted the problems). The finishing teams all finished on the original motor and
winners were AB Slotsport (aka Andy Brown- Searle & Les Bailey) on the very same
motor that ran at Pinewood last month, 2nd home was Dave Lees and Dave Bradburn,
followed by Peter Sidgwick and Peter Bowman. The other teams may wish to remain
A total of 11 motors were issued during this race, 3 survived.!
Is this a motor you really wish to approve for Novice racing?
