REFLECTOR: Deltahawk engine

[J.P. Brooks]

Gentle pilots,...   first, I don't set the pricing.
I believe it is $4000 extra.
People want power and power we deliver.  One could even run the engine at 
250 hp but TBO would be reduced.  Not being evasive here gents.  There are 
some differences that cost money.  Time involved with three engineers in 
the dyno, on the aircraft and digesting data takes a bit more time that 1 
day and they tend to like food with their meals......  ;-)

With intercoolers we've heard that you receive approximately 10-15% boost 
because your able to densify that much more air and add proportionately 
more fuel for a bigger "bang".
Doug has told me that the engine can take this extra pounding since we way 
over designed it, but that remains to be proven empirically.

We can always reduce the price, which makes you a happy pilot.  When we 
increase prices you are not so happy anymore.

Now for a short story: (eye rolls please)

Once there was this fine tuned factory that was maxed out putting out the 
finest machines in the world.  One day, the one machine that controlled all 
of production stopped halting the entire production facility.  The owner 
called the one and only person in the city that knew about this 
machine.  He came to the plant where thousands of employees were standing 
waiting for his arrival since this huge facility was idle now.  He stepped 
up to the machine, looked it over.  Opened his bag and took out a tiny 
hammer.  He gently lifted it and with one small stoke tapped the 
machine.  Instantly, it roared back to life and everyone scrambled to their 
work stations smiling.  The Owner said "send me the bill" smiling.  The 
skilled repairman send him the bill simply printed at $4000.  When the 
owner got the bill he was a bit angered at the charge.  He wrote back the 
Repairman and ask for an itemized copy of his bill.  The next week it 
arrived.  The owner opened it up and read the two entries.

Hammer: 1$

Knowing where to tap the machine: $3999


It takes money to find out the fit.  It takes money to flight test.  It 
takes money to get the knowledge of how it will  affect all other aspects 
of this engine.  In fact, we spent over $400,000.00 (USD) defending 
ourselves back in the late 90's because someone thought we had stolen their 
ideas.  We hadn't.  This is a clean sheet of paper genesis.  We burn 
through a tremendous amount of money a month just to slide that little key 
into the knob and turn it, AND, with no cash flowing in after 10 years.  We 
surpassed the 5 million dollar mark last December.  I know because I wrote 
the $100,000 check along with my wife's approval (great wife, eh?).  We 
would love nothing more than to give away HP, but again, gentle 
pilots,......   we can't.  But everyone who calls us asks us the same 
questions:  How much will the 200 HP go for?

Did anyone notice that the A4 is the same as the V4?   That did cost us 
some money and weeks of engineering on Carl/Dave/Doug and Deans part..

There I go again mouthing off where is should just shrug my shoulders and 
just say "shucks guys, I don't know".

I hope I get the chance to race Mr. 540 to 30,000 feet, or more.  "Oh no, 
not another challenge that I cant' fly now but must in the future."  JP 
just stow it till you can do it.
