Quote: "SortaSenator Bostonian. The Bostonian class seems to be becoming more popular in the UK, partly I am sure due to the low key competitions put on by the Impington club at their meetings. The models are a handy size, simple to build and can fly very well. The Impington club fly Bostonians with a 14 gram minimum weight rule (the same as the AMA outdoor rules), which makes the class accessible to anyone (it is not uncommon for entries to require ballast if they have been built too lightly)

Main rules are, 16 inch max wing span, 3 inch max chord, and all flying surfaces must be covered on both sides. 14 inch max. fuselage length, which must incorporate a box with dimensions 1.5 in wide, 2.5 high and 3 inch long. Clear windows must be carried with a projected area of at least 1 square inch. At least two rotating wheels must be carried spaced at least 2.5 inches apart so the model can sit on its undercarriage and ROG.

Many designs are cartoon versions of full size aircraft, and some others are caricatures of larger free flight sport models. The idea for the SortaSenator came from the well known SortaKorda Bostonian, which I think is an extremely cute model, and I thought I would give the same treatment to my favourite Keil Kraft rubber duration model, the Senator. This was the first rubber model I ever got to fly properly, back in the 1960s, so I have happy memories of it.

One stumbling block was the requirement in the Bostonian rules for a pair of wheels, whereas the Senator famously only has a mono leg. The solution was to hide the two wheels in the sub fins, so the model rests on those at the back, with the single wheel at the front..."
