RE: Sig 4 star 60 build
Brian, std servos will work just fine with that plane. I had a 4*60 which I sold and am now planning on building another....had Futaba S-148s but will also use Futaba 3004's or whatever JR / Hites / Airtronics has. You don't need anything fancy.
Planning on doing any kit bashing with that plane? I'm planning on removing one rib section from each panel (L & R), thus making it about a 65-66" ws....
