Well.. I've just got my pinkies on one of these beauties too. As I was surfing the web for an engine, I ran across the OS 110, and jumped over here to see if anyones tried it yet... and I see it's already being discussed.. as it does look like a winner for this plane in my book.

According to TowerSpecs... it weighs about 4-5 oz's less then the OS91pumper.. and about 3-4oz's less then the .91surpass. They also guage at using up to a 16x8 prop comparitively to the .91's guaging a 16x6(this strictly for comparison, as props will vary). This engine is modern in every way.. and I don't know that one could go wrong with it.(I'm talking myself into it). I'm actually hoping someones' already tried it and can report thier findings.. curious to know how compatible it is with a smoke system, etc..

Also ran across some other things/questions I'd like to toss out.. one is about the elevator set-up.. with the 2 pushrods collared together.. I totally understand the set-up, and wonder if anyone's using it.. or honestly if anybody thinks it's as cheesy as I do.. I'm all for using a proven set-up.. but have to totally question that one. Installing 2 elevator servos is totally within my capability.. and then I'm thinking about weight.. with a 19oz engine..and 2 elev servos in the rear.. hmm a smoke system would offset that nicely, quite possibly... just thoughts.

Rudder system.. On the box label.. they have a pic of a pull-pull system(in the little feature boxes).. Is there actually hardware in this kit for that? I havent ran across any yet.. I have to admit I havent even taken it out of the box totally.. I get too excited and its not time yet for me to actually start on it.. hehe.. I love this plane already.
But.. I can easily see a pull-pull system in it's future.. but just looking for different experiences.

Overall..I'm not one to change out a ton of stuff on a proven plane, as I do totally believe designers know how to design.. but do know kit-makers have to cut costs somewhere..and some do it in hardware/equipment.. and certain areas of most planes can use mini-makeovers, if nothing else just to personal-preference..

I've read this whole thread before(it's been months though, this was before I had the plane in my mitts).. and will read it again, as I know there's alot of answers to questions I'll have.. but I'm anticipating and speculating the future for this incredible plane.. I've wanted one since Sig kitted it years ago.. and am fortunate one literally fell into my hands thanks to a good friend of mine(Thanks Don!! You Da man!!)... So I won't go on here, but do appreciate any and all input. Thanks guys.

PS... Here's TowerHobbies link to that OS 110 if anyone wants to check it out. It sure is a nice looking engine!!
