Jac I have a noise statement but for the MT Propeller on my Jabiru Power Plant. Obviously it would not be of any use to you in Holland......BUT interestingly during our trip round the Baltic in the Summer we returned through Munster Osnabrook and we underwent an Airside Paperwork Inspection. All was well except the "Inspector" as a parting shot said I should get the MT Propeller Document converted to a British one since to apply it to a British Registration A/C was not suitable for purpose. Being diligent, on return I contacted the CAA at Gatwick and explained my demise having spent a considerable sum of time and fuel going to Straubing (Bavaria) to submit to the extremely professional test by MT Propellers would they give me a conversion document? Reply......... "Since the noise certificate is not a UK requirement on the Permit to Fly Light Aircraft they were unable to offer any help and even if I submitted to the expense of another noise test in the UK there is still not a document in existence to apply to this class of aircraft". MY reply was probably unprintable and akin to my recently saying "the French Authorities should take their heads from up their anus!" At present the German Authorities have accepted my Noise Certificate to reduce the landing charges and to date the Dutch haven't levied any increase! So it would seem there is a gaping hole in communication between the UK CAA and Germany and you seem trapped with a similar hole between your Dutch Authority and the rest of Europe perhaps? Me'thinks it's about time these people started "earning their corn" and became more positive to the confounded problems they generate by producing pure bullshit and paperwork. In the meantime Jac I believe the Europa Club have a document which "with tongue in cheek" just may help you but technically such a certificate should only apply to the one aircraft which has been tested. I have copied Dave Bossomworth in on this message and perhaps he will assist in seeing that the responsible person will contact you? Regards and Happy Christmas. (BTW whilst you are waiting for the paperwork you could get on making that chutney!)

I downloaded the video (52megs!). While mostly a promo piece for the company's stock, it gives a fair amount of useful info on the engine itself. In these days or high gas prices, there's nothing wrong with the prospect of a technology that would make current piston technology obsolete. BTW, how's that new panel working out?

Good to hear from you. Hope you're tearing along on your project! The panel looks great! I can't afford to populate it with goodies yet however! The white hot military UAV market is fueling all kinds of engine development right now. For 50 yrs or more, there has been no interest in non-jet engine technology from the military. Thats all changed now of course, the CIA wants extremely light weight, quiet and powerful engines for UAV's. Jets just don't cut it in this area. The spooks want to plant an RFID chip with GPS transmitters on any known Islamofascist or bad guy, trail him with a micro UAV for weeks on end to learn all his contacts, then fry him while he's sleeping. They can already do it, they just want to do it more cheaply. This story should convince anyone: http://www.msnbc.msn.com/id/10303175/ Officials: CIA missile strike kills al-Qaida No. 3 - International Terrorism - MSNBC.com All this new engine technology should filter down to us air experimenters eventually, unless there are so many UAV's flying around that they have to eliminate all non military airspace use!

They can't charge the military one price, and us about half of that. Our Defense Contract Audit Agency tends to raise an issue there. Perhaps that's why the price increases on the Rotax 914 have rather hefty in recent years. When you start selling to the military, seems your costs just....go way up. :-) Fred F. ________________________________ Message 7 _____________________________________ Time: 09:02:15 AM PST US From: "Cliff Shaw" Subject: Re: Europa-List: Detaching a Warp Drive --> Europa-List message posted by: "Cliff Shaw" Seven When I installed my propeller it went on bolt hole inserts.

The range is from 0.80 (at the lower temperature) to 0.95. Bare aluminum at room temperature is in the range of 0.04 to 0.06 depending on the surface condition.
