I was over in Blighty in September visiting family and hooked up with a homebuilder e-pal there (finally him in person) and he gave me a pile of the "Light Aviation" magazines. I must say I was impressed with how well organized the self-regulated LAA is, and the magazine's articles were very well written too. The mags put my luggage nearly 10 kg over weight, so they went into my carry-on backpack. It was an effort to stand nonchalantly upright at the check-in counter at Heathrow! I may have to re-think my engine choice if I decide to go the CH-601 route, but if I did go up to an engine larger than my A-75/80's then a bullet-proof CH-200 may work for me as well (if I could find plans for it). Chris Heintz's machines are the closest I can find to a "tin Jodel" and I admire the "KISS" philosophy of his designs.

It was either the first or second HD built in the UK and originally it had a 2 litre VW engine. It flew poorly with that engine - which was making 65 to 70hp. The rate of climb was around 300 fpm at sea level and the 'cruise' 90 mph On that basis I would suggest an HDS is a very poor choice - there is one locally with a Rotax 912 and even it is not a great performer. My HD with the O-200 was not a particularly good performer either - the O-200 makes most of its power at high rpm - which you cannot really access without a controllable pitch propeller. The 80hp Rotax 601HDs that I have flow were much better performers than mine with the notional 100hp from the O-200. They were of course much lighter the O-200 version is at least 65lb heavier. I would suggest that an A series engine is just not powerful enough to give you the 100mph cruise that you are looking for. Whilst the cost of a Rotax is pretty horrid, there is a good reason for it - it's an excellent engine! In Europe at the moment there is a reasonable supply of time expired 912 engine as Rotax do not rebuild them and the lregulations say TBO or 12 years - although the recent TBO increase has had an immediate effect. A friend of mine has bought 2 - which have both gone into homebuilt 601s. After 1500 hrs there were in very good condition - no wonder the TBO was increased! -------- Pete Morris Read this topic online here: http://forums.matronics.com/viewtopic.php?p=280354#280354 Checked by AVG - www.avg.com 23:35:00 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message zenith601-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Zenith601-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/zenith601-list Browse Digests http://www.matronics.com/digest/zenith601-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
