Title: Question for CD's Concerning P.40 Event
Post by: Crist Rigotti on June 24, 2008, 06:14:33 AM
1. Would you allow electric in the event?
2. How would you determine adherence to the .40 displacement rule?

In So. Cal.  both the Knights of the Round Circle and Valley Circle Burners have dropped any displacement requirement.  End of problem!

In the NW we in a closely contested battle appear to have voted out any displacement level as well, so electrics are allowed. no help to you there Crist, but thats what happened here. Of course we have yet to see Paul Walker build an electric profile so were still safe there,,,,,,

In other words the event name needs to be changed to profile stunt.  Then the guys/gals can run their big 60+ size engines.  DOC Holliday

Pretty much, Tulsa has dropped the displacement limit also...

We run "Profile" in District 3.

The CDs for our next Central California contest that includes Profile recently polled the troops and decided to drop the engine size limit (the flier says "any engine size").  Electric isn't mentioned, but I'm betting the intent is to eliminate engine restrictions altogether.   I'm also betting the rumor of an invasion by piped 60 and 90 powered profiles is about as likely as an invasion of two-headed Neptunians.   LL~  Profile is a casual, fun event and everybody in this area treats it that way.  How would you fit a RE pipe on a profile anyway?

BTW, the skill categories for Profile at this contest will be:  Beginner, Intermediate/Advanced combined, Expert.

We have two tuned pipe Profile Stunters in the PNW, both with OS .32's. One is Paul Walker's flying wing profile. AFAIK, he has never flown it in a contest. The other is the Prowler of Scott Riese, who campaigned vigorously against dropping the .40 limit. Scott flew it many times in P.40. There are also a few using the MACS Muffler, which kinda falls into the pipe catagory. I don't think the CF pipes should be allowed, but writing the rule to also allow the MACS Muffler would be tricky.

Our view is that if anybody wants to fly a big banger on a profile (especially, side mounted), they'll get a new respect for the vibration, structural and fuel system problems that will result. Maybe eventually solve them all, but maybe not. We know it can be done, but nobody has bothered. Jerry Eichten stuck a G.51 into a Brodak P-40 ARF and has been flying it awhile. I think this is its second year, BCBW, and Jerry says it works fine for him. This is a pretty cheap combination! I think a Magnum .53 would be a great engine for Profile Stunt, and just might find out.   D>K  Steve

Just drop the displacement limit altogether and make it an Open Profile event.

I heard of a 1/2A contest where they required that the electrics be limited to a 6" prop.  Similarly, you could limit the p-40's to an 11" prop.  That would sort of fix the displcement and electric limits at the same time...

Steve, not to be nit picky, Scot's profile is a Bob Hunt RD-1 actually, but yeah its a tuned pipe motor.I too was initially against the change, but alas, have come to see the error of my ways since I now campaign with LA 46s. Though I own several Magnum .53 engines and have a set of cores for a  Magnum that are sitting there looking for a project,,
of course there is still the 109 to finish, the Avenger that I need to proof for laser parts since people seem to want kits. oh and my profile 109,, hmm I wonder, do you think the .53 is overkill on a 570 inch profile,, maybe not?

We have dropped the displacement requirement for all Treetown Profile "40" type contests.

As I mentioned to Crist and Mike Gretz at Sig, as long as "they" know you won't win, there will be no controversy! ( :'( that's why Mike let me fly my Brodak Electric Super CLown at last year's Sig contest, and I certainly didn't disappoint the CD!).

And another point, the displacement issue is always so bogus--for example compare the Fox 35 to the Magnum 36 or Aerotiger 36, or..... Comparing displacement to electrics is bound to cause confusion and problems.

We've never used the displacement rule at the FCM contest either.  Fly whut ya brung as long as it's a profile.

I agree with Will. If it's a profile, bring it, fly it.

There are a lot of folks having fun with .46 LA's, huh? Not that many ever really enjoyed .40 LA's. Which aren't being made anymore, for good reasons. We need to be able to send folks to the LHS to get what they need, not send them to eBay.

If an area wants to stick with the P.40 class and .40 maximum displacement, that means .015" braided lines. So, I'd look up the electric rules and see where the electrics (by weight) have to change to .018" braids, and say that's the max weight allowed for an electric in E.40!   LL~ Steve
