Just replied to a similar more specific Artes Falcon post, repeated here :
Just thought I would add my current experience with the Artes Falcon. Out of all the range I thought this would fill a gap in the market nicely between the smaller 90mm cased engines and the ubiquitous 110mm cased we are all familiar with. The aim is to use for it to power my Super Reaper during the cold UK winter months, hopefully this should keep my hand in while next years summer projects are underway.
Received my Falcon from Felipe within 5 days of order via good 'ole Mr.UPS. Motor was quickly bolted to the test bench to check if this relatively small engine actually matched up to the manufacturers claims. To my surprise it turned out to be something of a wolf in sheeps clothing with my trusty digi thrust meter showing around 11.4kg or just over 25lbs at full power (126krpm)!! General handling was nice and smooth with good sub 4 sec. acceleration idle-full power.
Rough uncut video footage here
http://media.putfile.com/Falcon-189 Used my newly aquired micro video cam that I intend strapping to the Reaper for a bit of fun. Built-in microphone could not handle the db's so please excuse the poor sound quality which bears no resemblance to reality (just turn your speaker sound level right down).
Would be interested to here the experiences of other Falcon users.
All in all a very pleasant first experience. First flights are scheduled for next weekend so I'll report back then.
Rob.
