I was going to tell tobytorkn that a new SPA chapter has been started in New Jersey....
rainedave, I used to live in New Jersey. Would you happen to know where the new SPA chapter is? I used to go to Tony Bonetti's home field to watch people fly. Tony once took off my Tri-Squire for me and then handed me the transmitter. He was the fellow you went to, to get your Kraft radio worked on. I was hard on nicads back in those days.

I love 2 strokes (don't own a 4 stroke, in fact), but keep in mind that the OS91 is the dominant engine for good reason under the current SPA rules structure. If you fly a 2 stroke, you will be at a competitive disadvantage in SPA. Since I live several thousand miles from the nearest SPA contest, this is not a concern for me and I would use a ST90 to get the power in a 60 sized 2 stroke. It depends on how competitive you want to be. If winning is your goal, use the 4 stroke. If you simply want to compete with a classic aircraft you enjoy, then a 2 stroke will be fine and you can buy a bunch of extra fuel (cheap fuel, too - no 30% heli mix required) to practice with using the savings from the cheaper engine.

Thanks Mark. To me, much of the appeal is the look of those '70s pattern ships. Lengthening the landing gear would not be an option.
