hi all,
I have just got a sig LT-40 and it has a evolution motor with a cursuve looking a on it, can anyone tell me the size of the motor.
I think it may be a .46 Thanks for any info

My evolution has a 46 on the side of the head,I don't know anything about an A on them.

Can you take a picture of it and post it here??

My evolution 46NT has 46 stamped on both sides of the head also

Anybody know offhand what the TPS has stamped on it? Perhaps that's the one on the original poster's Kadet?

here are some pics they are blury but you can see the small a on iy and theres two small dots on bolth sides but i dont think they mean anything.

It is probably the trainer system engine that comes with the Hangar 9 Alpha 40. It is a .45 engine. If it still has the travel limiters on the high speed needle valve, take them off. They just get in the way.

I have burned a lot of fuel with mine, and it has been a great engine.

Good luck

Yes, that is the TPS it is a .45 size

yeah thats the one thanks alot. well it seems like a good engine. I bought the sig lt-40 with servos and a hobbieco nexstar .46 with servos all for 50 on creagslist. thanks for all the help!

Yep... it's a trainer system, I've got one... It's equivalent to a .46NT I believe, (The .46NT is no longer in production and was weaker than the .46NX) I could be wrong. It's a good motor, just remove the limiters so you can adjust your low and high end better like everyone said.

Also don't believe what the manual says about your motor already being broken in. Break the motor in anyway just to be safe.
