    I am a sport flier living in Connecticut where good flying fields are hard to come by. Most of my limited flying takes at a local school field.

    I am considering a Bostonian, just for fun. But I cannot find any straight prop shafts (the old Peck prop shafts). Gizmo Geezer sells a front end for a 7 inch prop. A bit much for a 16 inch span Bostonian. But if I blow it up to 20 or 21 inch span then a 7 inch prop should be OK. I would plan on a long thin motor for a long slow cruise at low altitude. I have several Bostonian plans that would make for interesting sport models. At least I think they would be interesting. I’m also hoping that a 20 inch span model will be a bit easier to trim that a 16 incher. Any comments on the wisdom of this approach?

    It sounds reasonable; a 20″ model should trim out a little easier than a 16″ model and if you don’t have to stay within contest rules, why not? We used to fly the Bostonian event and it was a lot of fun; I’m a power flyer but I remember building Walt Mooney’s Boston Found design, which was a good flier. As far as prop shafts go, even when the Peck prop shafts were available, most people used to bend their own from music wire with a pair of needle nose pliers. If I remember correctly, .045 wire is about right for a Bostonian. If you don’t have the nose plug, a small rivet or a piece of brass tubing epoxied into the balsa nose block works well.

    Thanks Simon for helping out…I would also suggest FFML or Hip Pockets sites

    Thanks for the replies. I have more Bostonian plans that I will ever build. I have memories (not especially fond) of trying to bend a suitable prop hook. That is why I went to the Peck prop shafts. My son has a couple pf Gizmo Geezer units and they look as though they are at least straight and somewhat adjustable. Sounds like a winner for me. Now I need to get of my model railroad duff and enlarge a plan either on a copier or with pencil and ruler.
