Steve Helmick's proposal to change the rules for the Northwest P-40 Stunt event to a simple Profile Stunt event was approved by Northwest control-line fliers in voting that took place from Feb. 11 to March 12.
A good number of fliers cast ballots on the proposal via the Flying Lines rules coordination process. There also was considerable discussion of the pros and cons of the changes, which can be reviewed by visiting the Northwest Message Boards.
The proposal was formally introduced in January. There was a month for comment, a month for voting, and now the rules take effect as approved. These rules will be in force for Northwest contests unless otherwise noted by the contest organizers. The new Profile Stunt event will replace P-40 Stunt in the Northwest standings compiled by Flying Lines.
What the proposal does: It eliminates the .40 displacement limit, raising it to .91. It also provides for electric power. It eliminates any reference to four-stroke engines. It also changes the name from "P-40 Stunt" to "Profile Stunt."
Note that any plane legal under the old P-40 rules remains legal for use in the new Profile Stunt event.
