alucard13: Online, try Speedtechrc.com or Acehardwarehobbies.
com. The RB X12 piston/sleeve/rod will fit also (the sleeve has
exactly the same timing cuts as the MR12 sleeve).

Default Engine selection?

I need some advice. I have a MT-12 motor and need another motor for a second car. I am thinking of a MR-12. What do you guys think of the Trinity motors and do you have any suggestions?

Default Re: Engine selection?

I saw this motor on the Tower website Trinity Nova Rossi .12 Slide Carb SG Shaft. http://www2.towerhobbies.com/cgi-bin...p?&C=GCS&V=TRI They have so many it is hard to choose from any suggestions would be great. Speed Tech is out of stock on the MR-12 which I prefer since I know my MT-12 so well. Does anyone know where I can find a MR-12?

I would stick with the Mugen - even though the MR-12 is short-rod compared to the long-rod MT-12, mixtures and consistency should be close.

I try to stay away from anything with Trinity on it. They tend to be way overpriced and underquality, although they do sell all the NovaRossi branded motors.

The Mugen is a Rossi based motor that is NOT sold by Trinity which makes me like it much better. . .

Hey Boomer, In your opinion would you stick with the MT-12 or is there a big noticable difference in the MR-12?

The mt-12 is a torque engine and the mr-12 is an rpm engine so it just depends on the track. For smaller tracks I would stick with the mt-12 but for the larger tracks I would go with mr-12.

I think I will give the MR-12 a shot. What do I have to lose.

Mt12- long rod= more torque
Mr12- short rod= more rpm
Like stated above choose the motor for the track.

I have an MR12 and i love it. If my driving was better I could easily keep up with the pros where i race. I have plenty of speed (sometimes too much...hehehe).

I tend to be a torque kinda guy - gimme a big diesel, big v8, lots o' torque and I'm happy!

I'm running an MT12.

Really, my advice was boiling down to "stick with what you know" - the Rossi motors are good motors and you already know the Mugen motors so I would stay with them.

The other part of my advice was to stay away from that Evil Empire that is Trinity.

Hope it works out well!
