withdrawn from the market due to lack of resources . we will continue to answer all e mail the website will remain for informational purposes only . the eureka was developed after recognizing that the current market does not offer an affordable ultralight that is also easy to build . eureka is a machine that can be put into the air ready to fly for about 8000 the price of a typical ski doo sea doo or other recreational craft . although there are ultralight kits available for about 4500 6500 prior to engine purchase they often require building and fabrication times that can approach 600 to 1000 hours for first time builders . this realistically translates into 2 or more years of building time that somehow has to be accommodated among other family obligations . it is a sad statistic that less than one third of purchased airplane kits ever get completed by the original purchaser . they either quietly wither away in a corner or they are sold at a fraction of their original price to be completed by someone else . we pre manufacture eureka sub assemblies in our facilities . wings tail empennage and fuselage are all pre built ready for bolt on . the wings are built around a single deep spar . there are 26 foam ribs in each 12 foot long wing . when this assembly has been built it is covered in full span panels of pre painted white aluminum skins durable and uv resistant . the resultant wing is extremely stiff and strong yet weighs less than 35 pounds . it is attached to the fuselage with just a few bolts and in about 5 minutes . one person can do this . this airplane can therefore be easily assembled in the field just prior to flight . this allows for transport on a low cost trailer and storage at home eliminating costly hangar storage or the risks of leaving the airplane at an airstrip unattended and weathering away . your investment is protected . the purchaser assembles pre built components with the supplied 3 16 and inch aircraft grade bolts and nuts . this means that 3 8 and 7 16 wrenches are the only tools required to assemble this aircraft kit that is why we are so confident that the eureka ultralight can be assembled in only 2 weekends in order to keep eureka s price low it was designed to fly with a hirth f 33 25hp engine with electric start approx . 2500 . alternately the zenoah gb25 22hp engine with pull start can be used approx . 2000 . both these optional engines have a solid history . we do not recommend higher horsepower engines at this time . the weight saving of over 25 pounds compared to the higher horsepower engines was therefore effectively applied towards an aluminum skinned airplane no maintenance instead of the more conventional dacron skinned types which are considerably more expensive and time consuming when it comes to bonding heat shrinking sealing uv protecting and finally painting . these tasks often intimidate the first time builder . they are obviated with eureka s pre painted baked on white aluminum finish . questions or problems regarding this web site should be directed to webmaster . copyright 1998 2003 ameri cana ultralights . all rights reserved . last modified july 2003 .
