hmm.. at first I wanted to say MidgetMustang.... its not that though.... I'm wondering if its someones take on the Tsunami... its that tail shot that leans me to that.. if it had the tips to go with it.. I'm just not sure.. but these suggestions may stir someones memory... Its a tough one... I'm wondering if pics of the inner fuselage might help.. at least determine a manufacture... hmm.. wish I could be more help... this is my best shot for the moment. At any rate, with that tapered chord wing... and that K&B it should be a sporty little guy though.
