When is the official race day?

Oh and if my engine fails to be impressive, you maybe should drop Paul G's mane from the description. I wouldn't want yo sully his good reputation.

As my friend Special Ed would say "Yaaaaa" congratulations to Rod!!!

Well everyone, I'm speechless
No, actually I've never been short of a word or two.  Hey thanks everyone.    Wow, I didn't think- Australia day today (a bit like Independence Day for our US friends).  Uncannily appropriate!!

I don't know what I did.  I took the engine I used last year (which came second last) and fitted one of Bernie's TD cylinders to it but damaged the new piston, so found another used one with good fits.  I damaged the prop driver (obviously in a rush) so ended up using another old crankcase I had.  The crank span pretty free so I reckoned it would be right.  Used the old TD head from last year and went & bought the right size drill bit which Paul Gibeault recommended for the venturi in his Mouse building tips.  Wasted my money because the venturi was already that size.  Used an old star shaped mylar reed I had.  First test (on 25%) pulled about 17,400 on my Tach, but the reed & clip came out and tangled up in the crank.  Fitted a new oval mylar reed and new clip and gave it another test at 18,000 rpm.  Ran one tank only through it, let it cool, cleaned it and threw it in a box headed straight for Missouri.  What did I do right?  It really must have liked the extra nitro & small prop.

The flabbergasted Rod.

GENTLEMEN!

What a fabulous effort by Kim & his Crew! Thank you for hosting this. Congratulations all around especially to Aussie Rod, our new winner.
What did you do right you ask?

1. You decided to enter even though you didn't plan on winning. "You can't win watching the fun from the side lines"
2. You KEPT GOING even though you damaged parts & even blew up the engine when the reed retainer came adrift.
3. You weren't afraid to keep MIXING & MATCHING PARTS as was certainly necessary.
4. You didn't buy into the: "you have to use a special head to go fast". Yea Olde Cox TeeDee head (from Bernie) is hard to beat for consistency, isn't it!
** The top three engines used a Cox head to good effect**
5. Finally from my Australian Speed flier & engine mentor, Peter Tilley. " When it comes to going fast... It's ALL in the prop & half in the engine".
That means the "right prop" matched for the purpose, makes for a REAL game changer. Can you imagine what 3 of these in the AMA Nats Mouse Final sounded like whizzing by in the same circle for 100 laps! It was absolutely exquisite!!

I will say that I would never have guessed the RPM's would turn out to be as high as they were. I've never seen more than 23,300 on 65% nitro at sea level on my VERY best mouse engine... My current motors won't even do near this anymore. My wife Dianne's motor (at home) only turns 21,500 at best... So the extra 2,000 RPM must have come from somewhere... I must conclude that the weather must have been excellent, the fuel excellent, and the prop excellent. There are unknowns, like the accuracy of the Tach, but to be out by 2,000 RPM is quite a stretch... So I cannot explain the HIGH RPM numbers. Bottom line though, it doesn't matter as long as the variables are consistent which of course they were. I can HARDLY wait for UNLIMITED!!

Cheers,

Paul (a.k.a. Mr. Mouse)

(Say Rod, I'm planning to drop by Sydney & Perth next year... would love to shake your hand & buy you a cold one. Maybe we could even talk shop over a 'Barbie'.)

Congratulations ROD !!! Man that is some outstanding numbers ! Good job Guys this is a real competitive adventure Looking forward to the next rounds . Kim you the MAN

Congratulations to everyone.
I thought mine, having seen it turn over 21k at home had a chance. After not being run or even opened up for two years, I never expected I'd go 21.17k. And have five engines faster than mine. Way faster. That was the one I built on camera following Paul's guidelines. I wouldn't have mentioned that if it had been under 21. BTW, I tried to take that silly looking red head off but it was stuck.Lol.
Thanks Kim, that was fun.
Rusty

I had mentioned that the prop would have a big effect earlier in the planning stages and was dismissed...

I will say I was expecting only a 1-1.5K jump in RPM though. The nitro helped a little I am sure.

Congrats to all you guys. And good job Rod!
