ORIGINAL: f3a05
The current generation of "2 metre" f3a models snap better than earlier ones, and they have smaller wings
than your Atlantis.
Have a look at the designs for Oxalys, Beryl, Integral(New Stephane Carrier model @ Zn Line), Genesis---They'll all have wing spans near 74 inches (1.88 metres) and wing area about 950 square inches(sorry, don't know metric for that!)
But---have you tried different control settings just for snaps? My Abbra (Made in the Czech Republic!) is OK for single snaps on my normal flight settings, but needs much more aileron. a little more elevator, and less rudder for anything more than one.
My wing area is 1003 square inches. I think that it is so much.
But I have used OS160FX and the weight of my model is 4900grams (172.8 ounces) and I´m afraid of wing loading, because a lot of models(oxalys, Beryl,...) are more lighter (4300grams=151.6 ounces) What do you think, should i do quite larger wings?
I have tried everything and finally I must have a lot of ailerons and rudder and i little of elevator, but it still isn't right. My friend have Rhapsody(too from JM composite) and it do snap rolls much better than my Atlantis.
I know Abbra very well. And the models from JM Composite are the most used in czech pattern flying.
