Proposals to remove Sport 40 Carrier fuel restrictions approved
Mike Potter proposed two changes in the Northwest Sport 40 Carrier rules that would either remove or reduce restrictions on fuel used in the event.
Both proposals were approved by a vote of Northwest Navy Carrier participants between Feb. 18 and March 18, 2015.
The effect is that Proposal No. 1, eliminating all fuel restrictions in Northwest Sport 40 Carrier, takes effect immediately and will be in effect for the first 2015 contest, the Jim Walker Memorial Spring Tune-Up in Portland, Ore., on April 19.
Passage of Proposal 1 makes Proposal 2 moot.
The vote results were:
Proposal 2: Eliminates 20 percent oil content requirement. If this passes, and No. 1 does not, 10 percent nitro fuel would continue to be supplied by contest management but there would be no oil specification. YES 83%, NO 17%
Rationale, as explained by Mike Potter:
Proposal 1: There is no performance gain to be had using more than 10% nitro in the OS 40FP engine. Tests have shown that more than 10% will cause engine over heating and possible engine damage. This rule puts undue complications on contest organizers and competitors for no real reason.
Proposal 2: The availability of exactly 20% oil ratio fuel is quite limited around here. It can be special ordered but in case lots at great shipping cost. The average modeler does not have access to this ratio fuel. I propose (if the fuel restriction is not lifted completely) that the rule requiring only 20% oil be eliminated leaving only the 10% nitro restriction in place.
