OS Seems to have the best rep for longevity of life and good support too.

My RB .12 has run reliably for two years and close to ten gallons of fuel. As far as O.S. goes, I ran nothing but in r/c airplanes for over twenty years with no problems whatsoever. While I'm tickled pink with the RB, my next .12 will be an O.S. due to better parts availability. Assuming I ever wear out that RB, that is.

my vote is the os 12 cz-z or the tr 12


my cz-z with the old os 10a carb is like a godly reliable engine.

i think the most reliable engine out there (in a .12) is the mugen mt12. you can ask many racers and this is probably their old time favorite. and it's even being used still to date as long as you modify it to keep up with the newer engines.

I'm still using a MT12, which is almost new, only one race old, and I love the engine! Pretty good punch for training, and it always works, and keeps going

But... Compared to my old over-prepped J-Tech Nova Mega, everything is reliable

i don't know of one that goes through all the details to modify a motor. but if you want your motor modified, it will be better to have proffesionals do it. a slight mistake on modification can lead to poor idling, poor fuel economy, and the worst which is a motor that will never run again. i've had this problem trying to modify my old motor. it never ran right again and i ended up buying a new one. but there are companies out there who will do it for you. go to www.rbmods.net and you won't get disappointed. they have premodded engine on sale (brand new motor modified by them) and you can send your motor in for mod.

The Nov. (or Dec?) 04 issue of RCCA has a great article on engine mods and this discussion is VERY good with lots of pics.

be careful though... one slight slide of that dremel tool and the motor is just not gonna be right.. angles, depth, how much you really take out and stuff like that all counts. also, every motor technically should have different kind of mod because of different timings. a mod for a particular engine wont be the same for another kind.

but then again, if you want to do it yourself, good luck and i hope you don't have to buy a new motor afterwards which will be a lot more than modification by proffesionals cost.
