Neptune engine?
 

Just purchased a Neptune here on RCU. I see that the engine size list a 40 to 46. I just figured I'd check around and see what engine others were using. I have a OS 46FX and a Irvine 53 needing a home and a couple of SF's. Also, on locating the CG, can anyone read the EXTREMELY fine print in the manual or is it just my old eyes? Thanks

My Dads Neptune has an OS 46AX in his and it rips up the sky!!! Mine is on the bench as i type this, and is getting an OS 50SX!!! A pond mate has one with a Magnum 40 or 46 (i forget which) and his goes very well also. We love ours, their by far the best made, best performing, and best looking of all the versions of this type:D

This one has an OS32 and is an absolute treat to fly.
Nice aerobatics but not ballistic power...

I also have one on the bench and am pondering my engine choices. I'm an electric power guy, but just might go with fuel on this one. I'm considering an OS FL70 (4 stroke) for fuel economy and low slime. However, what I'ld really like to try is a very small gasoline/spark engine. Maybe a .6 size 2 stroke converted to spark ignition and gasoline. Any ideas anyone?

OS FL70 is heavey, I think use OS 2 stock 46FX is good. If use 50sx, I think can hoving.
