<p>I have decided to design my own 4 place low wing and market it as a kit. I think something like the 640 is a good starting point for design, construction methods, etc., but its looks have fallen behind. Almost everything needs to be improved or totally redesigned. I'm planning on offering a kit that has almost everything determined, like the SlingTsi comes with the Rotax Tsi... mine will come with a specific engine. Auto repurpose, Turbo, FADEC.

<p>Zenair management has made the friendly suggestion that since the CH-640 is a now discontinued model that discussions and comments be moved over to the forums that exist now for the other discontinued models</p>

<p>its not easy to make a living these days… so I don’t second guess management and the decisions made concerning the CH-640</p>

<p>if a company was to pick up the CH-640 and re-brand it</p>
<p></p>
<p>it could be done with very little cost respectively </p>
<p></p>
<p>an offer could be made to solicit orders for the tail kit… they would not even have to lift a pencil or click a mouse yet on the plans…. Just see if their is interest in the kit</p>

<p>if not they can walk away … no harm no foul</p>

<p>I wrote to the owner/CEO of Sonex</p>
<p></p>
<p>i hit my knees and asked them very nicely to consider the CH-640</p>
<p></p>
<p>Sonex does not have a 4 place aircraft…. The CH-640 is a ready to go… proven design </p>
<p></p>
<p>The CH-640 looks at home with the low wing Sonex line…The CH-640 was out of place in the high wing line up</p>

<p></p>
<p>my suggestion was a license agreement or out right purchase </p>
<p></p>
<p>Zenair could still provide hard to fabricate parts like main landing gear legs and canopy</p>
<p></p>
<p>the best thing would be for a company to do the CH-640 as a kit and not scratch build..</p>
<p></p>
<p>Sonex has the in-house resources to bring the CH-640 plans into the modern age.. pre-punched kits… ect</p>
<p></p>
<p>also to take a fresh look at the back seat to make it a better 4 place.. lower the floor… raise the canopy a little to make riding in the back a better experience… also a baggage door/area under/behind the backseat… as the CH-640 has load capacity to spare </p>
<p></p>
<p>im asking all of you …. If you love this plane… then write the letter… to Sonex or whomever … to look at this fabulous aircraft …, it deserves a second life in a new home</p>
<p></p>
<p>I BTW own plans for the Sonex A and the CH-640</p>

<p>I never saw anything about this model until now! It's no wonder there is no demand. No one in the last 5+ years knew it existed! I would be seriously looking at that as my next kit right now if it was an option. If we dont know about it, it's hard to say we want one and buy it.</p>
