Tamiya FS15LT nitro motor

[Renegade88(2)]

Can anyone give me the factory screw settings on this motor? How reliable are these motors and how long do they last?

[Disco]

The setting of the motor is different for each engine and for the conditions on the day. I have found the engines are fairly reliable but do not last very long, losing compression quickly. When it wears out you could replace it with a Novarossi or similar which last much longer, produce far more power and are easier to set in my opinion.

How are OS engines?

[Disco]

I race 1/10th ic on road national series an found Novarossi to be virtually indestructable, OS motors in my past experience (with .21 engines in rallycross) are not as powerful or as reliable. Over here there is virtully no one running OS as most seen to lack power, Picco/Colari are the quickest motors , but difficult to setup and don't last as long as Nova's.

All the above is my personal experience and is only an opinion.

I like OS, their products are very well made. Very high grade bearings definitely, that don't leak oil out the front, easy to tune and the carbs keep their settings well. My engines always start first pop.

Few yrs ago when the 1hp Novas came out the OS was a bit behind the power 8-ball, but these days with the CVR Hyper I think OS is back in the hunt. Anything at that power peak would give you more than enough power for a narrow touring sedan.

I have a choice between a OS 15CVR and a Tamiya FS15RS, help me decide or what would you take?

[Disco]

If i had the choice of those two i would take the OS every time, should be more powerful and reliable than the tamiya.

The OS15CVR is a well-regarded all over the world, but the new Tamiya engines (that came out in last 12 mths) are also pretty good now. If you're thinking of racing then check if you can use a 15, you might be limited to a 12 when you put in a non-original engine.

Original is a 15 I will go for a os15cvx

Hi, Your starting point for most two-stroke engines even the more complicated whippersnipper/line-trimmer engines are as follow: the small screw on the right is air control and "one turn variate", now the fuel adjuster is "three turn variate" alike the low-mixture screw starts at full tightness then adjust-out! Note always make sure you do not leave ya glow-plug starter in-place after ignition!! And if its a well-used engine always make sure that there is no oil calcification or oil jelly build-up in the low-mixture hole and cavities?

All the best, 3turncarby.
