Although we have still sold more Core than Atom in the time since it was released, I have 6 happy Atom users flying them and I tweaked the set up on two jets using Atom at last weekend’s Elvington Jets. The Cayman scheme Rebel 2m is an exact match for the four Core controlled ones in my local club, so I shipped the radio with a Core model memory copy to help the first time jet customer. Normal model memories can probably be transferred between them 90% of the time.
