I guess I'm the only guy who still likes the OS 1.2 FS.
My SIG 3D Mayhem ARF is "in the mail"-should be here tomorrow.
I will put the very reliable 10+year old OS 1.2 in and see if it will get off the ground. (It hauls my very old original 8.5 pound Dragon Lady out of sight)

I've never mounted this engine inverted. Any thoughts on mounting engine on its side in this airplane?

Any ideas for muffler other than the original.

I've got to buy new servos - how about a recommendation for servos that will not break the bank?

Seem like Christmas Eve!
