RE: Best indoor foamy for F3A practice
The F3A shock flyer is quite simply brilliant! I've had quite a few of the indoor "shock flyer" type models and this is far and away the best I've had the pleasure of owning and flying. Indoors it will fly at a walking pace and is the best natured indoor model I have seen. All of the "3D" manoeuvres - rolling circles, prop hanging/torque rolling, real high alpha stuff is a breeze. Plus the more "F3A" style flying too, you can do loops rolls stall turns in fact all of the proper pattern manoevres indoors with ease.
Outdoors and with a slightly bigger battery (850mAh 3c lipo) for penetration into the inevitable breeze, it comes into its own, being more than capable of all of the current F3A schedules with ease, I know I've tried them!
As with all of these models, for the slower indoor flying, the CG is critical. If it is too far forward it will mush and stall around with little control. Get it back so that you can fly inverted with no down elevator to fly straight and they come into their own.
They are great for teaching you the intuitive control response that you need to fly F3A naturally. Learning to torque roll with my shock flyer has taught me more than I ever imagined and has helped my competition F3A flying progress faster recently than ever before. Have fun!
