What about the ARF PF? I just bought one on emergency from Tower after I stuffed my kit built hand me down Primary Force. Just as the engine was dialed in and sweet. Overconfident I could yank a lower vertical eight loop after starting too low. Anyway, the ARF PF is simple and hassle free to glue together. Very little work. As easy as a Streak ARF. My PF definitely kicked the butt of any Flite Streak made to stunt that I've seen. This based on my direct observation, having flown Streaks for a number of years, including a season competing in Beginner with an ARF version. Seems to me as a serious stunt trainer/competition plane, the Primary Force wins hands down. It's as easy to trim and assemble as a Streak, since it has no flaps and it points and smooths the maneuvers much better. Beats me why it costs 2 and a half times as much. Nevertheless it's a more capable piece of work. The Brodak ARFs give a lot more bang for the buck, true, but flaps complicate assembly and tuning. As for getting in the air quick with an effective plane, the PF works much better than an ARF hollow nose in my humble opinion.
