Well it sounds like a great deal but you gotta bear in mind that the DL-50 is out there selling for US$370 including shipping ( ignition and muffler included ) and thats not just an introductory offer, thats what the normal retail price is !!

In all honesty if your plan is to push it up to US$ 439 then its not the greatest deal out there besides that at least we have lots of flight and test reports on the DL-50.

Just speaking openly as to what went through my mind when I read your post Tom.

On a side note can you post the complete specs of the engine ?
