RE: Sig Extra 300XS
I had this with the FX 1.60. Was a great plane. Landed like a trainer. And I'm not kidding either. Had a Bisson pitts. Was a very stable flyier. Very good quality arf. The 1.60 was enough for me since I didnt hover or do any 3D stuff. It would do everything I wanted. You wont find a sweeter running engine. NEVER had a deadstick with it, and that was with no on-board glow either. I sold it cause I'm into warbirds now, but I really miss it. Feel free with any questions.
