Thread: The Threat of Overpricing

Good value is in the eye of the purchaser. I’m not a good builder, but I thoroughly enjoy renovating an old airframe someone else has built.

Some people wouldn’t worry over a £35/ month phone contract ( £420/year), try and get them to spend that on a secondhand airframe! Personally I could quite happily live without a phone....I’m told I need one by Mrs Cymaz

Aerostar prop are good. Very little if any balancing needed and a lovely varnish finish. Several club mates have started using them.

Her ladyship now resides in my garage. The weather is too dark when getting back from work to assemble it in the evenings. Next weekend it will all be put together if the weather holds. We’ll then run the engine up again.

That’s a 26x10 Aerostar prop on the bench

The following is an actual question given on a University of Arizona chemistry mid term, and an actual answer turned in by a student. The answer by one student was so 'profound' that the professor shared it with colleagues, via the Internet, which is, of course, why we now have the pleasure of enjoying it as well:

Bonus Question: Is Hell exothermic (gives off heat) or endothermic (absorbs heat)?

Most of the students wrote proofs of their beliefs using Boyle's Law (gas cools when it expands and heats when it is compressed) or some variant.

One student, however, wrote the following:

First, we need to know how the mass of Hell is changing in time. So we need to know the rate at which souls are moving into Hell and the rate at which they are leaving, which is unlikely.. I think that we can safely assume that once a soul gets to Hell, it will not leave. Therefore, no souls are leaving. As for how many souls are entering Hell, let's look at the different religions that exist in the world today.

Most of these religions state that if you are not a member of their religion, you will go to Hell. Since there is more than one of these religions and since people do not belong to more than one religion, we can project that all souls go to Hell. With birth and death rates as they are, we can expect the number of souls in Hell to increase exponentially. Now, we look at the rate of change of the volume in Hell because Boyle's Law states that in order for the temperature and pressure in Hell to stay the same, the volume of Hell has to expand proportionately as souls are added.

This gives two possibilities:

1. If Hell is expanding at a slower rate than the rate at which souls enter Hell, then the temperature and pressure in Hell will increase until all Hell breaks loose.

2. If Hell is expanding at a rate faster than the increase of souls in Hell, then the temperature and pressure will drop until Hell freezes over.

So which is it?

If we accept the postulate given to me by Teresa during my Freshman year that, 'It will be a cold day in Hell before I sleep with you,' and take into account the fact that I slept with her last night, then number two must be true, and thus I am sure that Hell is exothermic and has already frozen over. The corollary of this theory is that since Hell has frozen over, it follows that it is not accepting any more souls and is therefore, extinct..... .....leaving only Heaven, thereby proving the existence of a divine being which explains why, last night, Teresa kept shouting 'Oh my God.'

I had an appointment to see the urologist for a prostate exam. Of course I was a bit on edge because all my friends have either gone under the knife or had those pellets implanted ......

The waiting room was filled with patients.

As I approached the receptionist's desk, I noticed that the receptionist was a large unfriendly woman who looked like a Sumo wrestler. I gave her my name.

In a very loud voice, the receptionist said, "YES, I HAVE YOUR NAME HERE; YOU WANT TO SEE THE DOCTOR ABOUT IMPOTENCE, RIGHT?"

All the patients in the waiting room snapped their heads around to look at me, a now very embarrassed man. But as usual, I recovered quickly, and in an equally loud voice replied,


The room erupted in applause!

May I suggest that you invest in a copy of Kwrmode's Mechanichs of Flight. First printed in 1930s and stillin print. Amazone an Ebay will have copies.

It explains aerodynamics and angles etc in simple terms

Kermode also wrote , Flight without Formulae , another essential read.
