Speaking of power

Bryan,

I can send you the exact prop you ran last year!!  Tho the tips are a 
bit beat up at this point, so I'll make a new one (and test it first).

How soon do you want them and how many?  I have plenty of the stock 
prop, but only 2 of the 11" versions right now.  I can probably get one 
done this weekend and send out to you, and then make more after the 
Trials.  And your address.

For injectors - Stokes said he would let me know ASAP when he could 
have something to me - I haven't heard - but then again, I figure 
the "green shirt" guys would get priority - and I know both you and 
Jason are in need of injectors also.  How soon will you have the 
injectors?  I am borrowing an RX from my Dad this weekend and planned 
some surgery (which I really don't want to do) on the #2 plane to get 
it flyable with the RX (minor setup needed, but biggest issue is 
needing the injector).  If you could send me one pretty quickly, that 
would be great - I need to have the plane in the air somewhere around 4-
5 June to make it worthwhile to take to the Trials as a backup.

For your homemade props - I would love to talk to you a bit more about 
them, and give them a shot - but again, not until after the Trials - 
I'm trying to really dial in the details on both the P03 and F03 - and 
get some more base proficiency with all the d*mn rolling circles, 
rolling loops, and the other weird stuff that might show up  in the 
unknowns (if I make it that far).

All of my contact info -

22 Norwood Court
Medford, NJ 08055
H 609-714-3544
W 856-780-9009 (not for public)
C 732-267-5296 (not for public)

Sorry I won't see ya at the Trials, but the NATs won't be far behind.

Thanks again for the offer of the injector - hopefully the timing will 
work out - because then it will save me some time and add some 
consistency.

Dave
