Default Trinity Monster Horsepower stock motor

What's been your experience with this motor? Is it faster than anything else out there in stock? How do you tune it? Thanks for any info.

Default Monster Stock

coolrcdad;

My experience has been good. The MS is a VERY high RPM Motor and performs best when geared as such.
You will want to gear about 3 teeth smaller on the pinion when compared to a P2K to start.

I truely believe that most people are over gearing their MS's. What I have found is that instead of "gear-up" try gearing down until the car slows down. The exact opposite of what one would normally do, but it seems to work with these motors.

I've never fried a GM3. I know you need to gear the Monsters way down. Reason I posted this thread is to get additional feedback to what I saw at my club yesterday: winning stock and 12th scale stock racers used this motor. I've already invested a lot in Fantom stocks (P2K2 and GM3). Has Trinity upped the bar?

Trinity in a sense has upped the ante. The MS needs to be geared down similar to the GM3, but lower. You are looking between a 7.2 to 7.8 final drive ratio on a touring car, not sure on a 1/12th scale or offroad.

Absolutely right, I've NEVER burned up a GM3 or Monster because I make sure I NEVER overgear it. There's no point in gearing one as high as you would a P2K 2 or P2K(or MVP) when they don't make good torque at low rpm & few people have the batteries to push one with that gearing(that's why the factory guys can get away with it, their batteries have more voltage & lower resistance than most any of us have access to, so they can still get good acceleration form such a tall gearing, & of course they couldn't care less if a motor burns up when their motor guy has 10 more waiting at the ready. Not that I'm complaining, it's just that we mortals simply can't do things exactly the same as they do). As for gearing my Monsters, I've had some good luck gearing mine at around 7.5-8.0 final drive in my TC3, depending on which one I'm using(some have less top end but a bit more torque so I can gear up a bit), & this is on both a medium sized & fairly big track(the big one being S&N's Trackside in Milwaukee). Just take care of it & I think you'll be pretty happy with them...

Well said Grizzbob. Its hard to believe but I keep finding myself gearing the monster about the same as I do my 11 and 12 turn mods in my XXX-S! The motor loves low gearing as well as lighter tension springs compared to what I used to run on my P2Ks.

Thanks guys. We run a TC3 so the drive ratio suggestions are great.
I see that Putnam Propulsion is tuning a version of the Monster (RC4Less sells them). I wonder if Fantom will follow.

Exclamation MONSTER Horsepower Stocks

hey guys ... I am kinda new to this sport ... ( in it about a year now ) but I love these new trinity motors. heres what I have ...

MHS pro p/n RC2141 .... heres the rundown on the label ....

21358 rpm @ 5.0v
66w @ 10.4 k rpm
49% @ 14.8 k rpm
99.1 nmm

now I may have gotten a freakinstein motor but the torque and power draw are very close to three of the four GM3's that I own with the efficiency being a little better and the rpm's being just out of the ball park better .... for example

GM3 pro p/n RC9427

19788 rpm @ 5.0v
64w @ 10.4 k rpm
48% @ 13.8 k rpm
100.5 nmm

now ... the GM3 listed above has only two skims on the comm and new serrations on the stock brushes. the MHS was box stock. both were broken in for 600 secs at 2.0v on a turbo 35 ( per the instructions of a fast guy at our track ) ... the GM3 in practice geared 37/96 ( 64 pitch ) was about average. it kept up with the packs of stock racers when my driving skills allowed ..... now the MHS geared the same was just a touch slower than some guys running chamelon 2 motors ( 19 turn ) . the fast guys at the track told me when changing motor styles within a brand look at the torque the motor produces and gear up or down depending on that for the new motor .... my MHS comes off after a race ( 5 min ) just slightly warmer than my GM3's but not burning hot or hot enough to blue the comm or the brushes ...

this motor with my bad driving moved me from middle of the C main to lower-middle of the B main and I was able to gain spots in the B because of the speed to make up for my driving problems.

I love this Freakinstein motor Trinity made.

There's gotta be something up with that motor, or you run on a very big track and you have the throttle control of Masami...... My guess is the former not the latter...
