Anthony,

I hope you arent planning on running an OS 1.40RX on this plane. You will be underpowered. This plane is HUGE compared to some other ones out there and is really draggy. By mid July when the NATS comes around and it gets really hot out, the 1.40RX will have problems at the tops of some verticals. The OS 1.60 would be great if you want to stay two stroke, but i'll warn you now, the 1.40RX would be under powered. I think Mike will agree with me. His V2's were 9.5lbs and at the 2006 NATS with the temps in the upper 90s, he was hurting.
