Minutes of Meetings and Decisions
C Can Motors
BSCRA has been asked to clarify the requirement for Group 12 motors
Shortening of 'C' can motors is not one of the "Permitted Motor Modifications" in the BSCRA rules. Therefore, shortening of 'C' can motors by any means is not permitted in the “restricted motor” classes. (Motors are of course free choice in 1/32 F1, 1/32 sports and 1/24 Eurosport) The moulded flange register on the endbell must engage with the full length can at the full length end.
Brush Hoods may be modified to allow clearance for springs and shunts to have improved travel.
Clarification will be added to the BSCRA Handbook
BSCRA has been asked to clarify the requirement for armature tags, the BSCRA council has agreed the following
In classes where Group 12 or Super Wasp armatures are required, the scrutineers need to check the armature is eligible by reading the tag, If the tag is missing or impossible to read the arm will fail scrutineering.
Motor Approval Policy -
BSCRA has decided it would be useful to clarify the motor policy. This clarification summarizes what the Association (under both the BSCRA and ECRA name) has done in the past so is not a change to existing practice.
Inline with this, the Cahoza motor cans currently approved for BSCRA 1/24 open group 12 racing will continue to be eligible for this class. ( USRA approval of these products has been withdrawn for price reasons.)
The wording added to the BSCRA Motor Approval Policy is-
"When BSCRA approved products are no longer manufactured, they will normally continue to be eligible for BSCRA racing. Normally racers wouldn't want scrap their existing motors just because new ones are no longer made.
Where USRA withdraws approval for a product it previously approved, BSCRA will investigate the reasons. Generally if USRA approval has been withdrawn for distribution or price reasons, BSCRA is likely to allow its continued use. If however USRA have found technical infringements, particularly performance related ones, BSCRA may well decide to withdraw approval for BSCRA racing."
Rule clarification for INTRO 32
We have been asked to make it clear if soldering the axle bushings in the Genesis chassis is permitted. The BSCRA Council has decided by a majority vote that soldering will be permitted, so the Intro 32 Assembly rule 9 now reads.
9. The axle bushes may be soldered or bonded in place
Rule clarification for BSCRA 1/32 Saloon, Super Production and 1/24 Open Group 12 classes
During the rule change submission process, the CRC have reviewed the permissible modifications to G12 and Super Wasp motors in the various classes. Having looked at some of the ambiguities in the rules and what has become common practice, the CRC have decided to issue the following clarifications about permissible motor modifications in each class..
The motor shaft diameter may be reduced at the drive end of the motor in the 1/32 Saloon, Super Production and 1/24 Open Group 12 classes
(NOTE this allows the use of small bore pinions in these classes)
Rule clarification for BSCRA 1/32 Production classes
Soldering of the original can end bearing is allowed on Falcon 7 motors.
(NOTE this was introduced as some members have experienced the bearing coming loose.)
Rule clarification for BSCRA 1/24 Production, 1/32 Production and 1/32 Super Production
(Rules E2 and H2)
This clarification explains the BSCRA's interpretation of the following rules:
H2.1 Only the following metal chassis of one material are permitted:
E2.1 The following chassis only may be used:
E2.3.5 Nothing is allowed to be added to the chassis in front of the forward most part of the motor unless otherwise stated in section E.2.2.
It is not permitted to undertake post manufacture heat and/or chemical treatments and/or shot peening to Production chassis components (Centre sections or Pan sections).
Note 1: For the avoidance of doubt this means any such treatment by any person other than by the original manufacturer in the original manufacturing process. Thus it is not permitted for entrants or intermediate suppliers to treat these components, whether by chemical dipping, replating, heat treatment, or addition of any substances including in solid, liquid or gaseous form or any combination of the above.
Note 2: This does not prevent the use of normal soldering or gluing operations on the chassis components to the limited extent specifically permitted in the regulations. Nor does it prevent straightening of bent components.
Note 3: Production car chassis are not eligible under the BSCRA regulations even if the treatments described above are undertaken by the original manufacturer beyond the specification of the approved product.
The exiting rule interpretation "The manufacturing processes of some chassis mean that some parts are delivered with quite sharp edges. It is permissible to deburr these edges. This must not result in excessive material removal and any such edge radius must not exceed 25% of the sheet material thickness" apples to BSCRA 1/24 Production, 1/32 Production and 1/32 Super Production classes
The above decisions were taken by the BSCRA Council on the advice of the BSCRA Competition Rules Committee
