Solid performer, but like all motors, you need to be at the right gearing/roll-out. I've been running against the fastest motors out there and have had no probelm hanging with them.

I guess before you decide to put a heap of cash and power into the car, you might check your setup and gearing for better speed/handling. To many times have I seen people go for the power thinking it will fix everything and then they end up in a lower main than before and having tuning issues.

My suggestion is: save money, have fun. On track with a straight less than 150ft, lock out the two-speed and stick with one gear. For an NTC3 with new tires, I'd suggest 21/54. For tracks over 150ft on the straight, I'd go with 21/54, 25/50.

Having found the right gearing/roll-out/setup, allows my meager 1.2hp motor to pull away from the pack.

I'm in no way a motor expert but talk to other who race in your area, get their advice, get their settings, and go have some fun!
i do too run the OSTR and the best part is when i win a main and the guy that comes in second cant believe it when he sees the engine that i have

Many times, these engines with Mega power are overkill for the driver. If you have an engine with "enough" power to match your skills, you'll most often be more successful. I won my first race ever with an OS .12 Hyper engine against Nova C12s and Mugen MT12s.

Default Durability

Another oversight some people make is that fact that the heavy tuned motors are harder on their cars. I re-check my entire car each week as a practice I follow. It comes from years of running low-wind mod motors in electric. When running stock, I still wrenched as much but saw much lower stress/wear on the car.

I believe this premise applies to Nitro cars as well. I think with motors in the 1hp range, your car bearings, transmission parts, etc should all hold up really well (kinda like a 19T in electic). You run a Muran mod motor, that like dropping in a Reedy KR 8 turn double aat about 18 degrees of timing...watch-out!

I guess my point is you need to consider the effort you need to make to support the hard-core motors, their tuning, the wear factor they cause, regular maintenance, etc. So far for me, no bad bearings, no fried 1-way, no bent dogbones, overall little or no wear to speak of from an OS 12TR.

My advice: If you do purchase a high-end motor, it's worth the time to go through your car, get it in perfect runnning order. Then break-in and set the motor up correctly per the manufactures suggested settings. Then I would document your setup completely and then check the car every other race to make sure the setup is still intact. Maximize your fun and minimize your frustration!

MUGEN X12 COMMENTS

"Well, after very very close inspection of the X12 I can say it is longer stroke than the NS12. When I first compared the two it was by eye, when comparing the two with instruments the ports on the X12 and NS12 are in different positions and the crank pin is higher on the Mugen motor".

Murnan Modified Engines


"Iíve got my x12 modified by Uriah Murnan and this thing is ballistic. Iím spinning 35 shore tires a good 30ft down the straight and I have barely gotten the engine over 200 degrees. These engines are screamers. Robbie at Mugen said they used a short stroke conrod with a longer stroke p/s, but they moved the pin on the crankshaft out a little more to get a better power band and let me tell you it worked. Thanks Uriah I love this motor".
