As the Hungerford model flying club had hired a local school in Newbury for a a few indoor sessions I thought it would be nice to build something new to fly.   Inspired by Pepeimc's build I decided to give the Zippy sport Bostonian a go - it seems to suit the Bostonian "conversion" very nicely.  I put my serious projects on the back burner for three weeks and had some fun building something simpler using any old wood I had lying around. The only modification from the plan was to enlarge the fin slightly, based on pepeimc's experience.  I used pre-shrunk blue Esaki for all the flying surfaces, and unshrunk for the fuselage. It was SO nice not to have to get the airbrush out  Smiley  Glazing is cut from the window in a supermarket cake box.  The fuselage stripes are from notepaper attached with glue stick.  It came out over the 14g weight minimum by a couple of grams, but it's only for fun really. 

It trimmed our fairly easily once I had jacked up the tailplane trailing edge by 1/16", explained by the fact my C of G was rather further forward than shown on the plan.  It was determined to fly right, so I let it and was quite lively on a loop of 1/8" - it got up in the roof at well under full winds, so I'll try a smaller motor next time out.

Looking very nice. The fuselage seems to be only a bit wider than the origninal...
Have fun with it.
