Summary: Anybody use Microsoft Flight Simulator for training?

I was surprised when I got no reply (over the holidays)
so here I go again...

Anybody using Microsoft Flight Simulator for training?
How about other software?  I'm looking to buy a joystick
(for my Mac), any suggestions?  I thought my first posting
would generate some interest since I hear from experienced
flyers that training on a PC is very useful and easy on the
pocketbook.  I'm also kind of surprised that the FAQ makes
no mention of this topic.

But hey, what do I know?

I notice that some of the electric motors sold for R/C cars and trucks
feature adjustable timing. What is adjustable timing and what does it
do for you?

Thanks in advance for your responses.

Well, you can invert the cylinder and you can invert the needle valve.  The
Black Widow I had didn't have a clunk inside the tank.

Interesting solutions and I already used then for another canard pusher
I never flew, but the point of the Astro Blaster is to have a .049
attached to a dummy rocket engine so you can fly either rocket boost
or .049 depending on how much money you've got.  For that, you'd pretty
much need a tank mounted engine and tank mounted engines can't handle
both inverted flight and a pusher configuration.

Although I don't have any of the original Monokote any more (and I

I have an ISP Chaperrell, which is basically the same model without the
fancy box (and about $5 cheaper!). My guess was that the ejection coil/
baffle wasn't the problem - more likely the ejection charge didn't 
fire if the 'chute didn't deploy. Either that or the nose was sooooo
tight that it kicked the motor instead of blowing the nose. A lot of
our members fly AeroTech/ISP stuff and I have never heard of the coil
causing a problem.

There is, however, a danger in the way the plastic shock cord mount
and coil assembly fit into the top of the engine tube. Twice I have
seen member's models pull that plug out on ejection. My suggestion
is to use alot of epoxy on that joint, and maybe lengthen the cord to
reduce force on that plug. Once you pull that out, its a real bitch to
get it back in and secure. (I found this out *after* I built mine...)

Probably not.  A&A Engineering sold a single-pad unit with this feature,
and couldn't sell enough of this unit PLUS two other designs to stay in 
business.  A multi-pad unit would have even a smaller market.  

Note that a pad that does not require positive human control to launch 
the rocket violates the Safety Code.  It would be compliant design, for 
example, to require the launch officer to hold down a button during the 
entire countdown -- but this would not be a popular user interface.  A 
design that allows the officer to punch a button to START the countdown 
and then nothing else is dangerous because the pad may blow over, an 
aircraft may appear overhead, etc.  Including a button to punch to abort 
the countdown sounds good, but is also unsafe, because when the pad falls
over TOWARDS YOU, you may be too rattled to find the damn button (or your
reflexes may say "the hell with the button" as you speed away).

   If you have access to video editting equipment you might be able to count
fields rather than frames.  Standard video is 30 frames/second with each frame
consisting of 2 interlaced fields.  This gives 60 fields/second, which is a
little better time resolution than the .02 seconds you want.

Look in model airplane rags. Tower (or similar) sell the same

same. They also have gel cells for a few more $. The R/C people 
use em for those electric starters and power panels.

The one in your car is, overall, the cheapest one.  Go to Radio Shack
and buy a cigarette lighter plug.  Solder some #14 or better wire onto
it and connect it to your launch system.  Doesn't work for relay systems
of course, but using that sort of stuff assumes price isn't much of a
consideration to start with.

My wife thinks I'm nuts, however I'd appreciate any input along these

Nothing special, mind you, but I suspect I'm recreating the wheel, and 
there must be an underemployed aerospace engineer with time on his/her 
hands to get into this project.  :-P
 
I'm doing all this with a scaled-down version of the V2 in mind, which 
will not require guide lugs for launch and for control of high-speed 
flight.  
 
The specs are: 1/6 scale, weight @ 30 lbs, engine ISP RMS K-550.

some small motorcycle batteries at a store today for around $19.00;
however, they aren't initially charged.  I'd have to spend another
$30-$40 to buy a battery charging system.  Is there a less expensive
route I could take?  Are there 12V dry cell batteries?  (You can
probably tell that I am "battery illiterate".)
