Hi Terrence,
The one I have now was built for a Product Review in my Products Column back in Stunt News..
It HAS movable flaps, as does the recent ARF ELECT.Super Clown Aaron picked up. We haven't flown the ARF ELEC. yet, but will soon.
They fly fine with flaps, of course, but there is a difference with out them. I saw no real improvement over the old flapless one I had... In fact I , personally, liked the one with out flaps better. A bit smoother but no loss of turn. It's all just a "preference thing"! LOL!!
