Great lesson so would you think a short stack design would be advantageous in USGT or does it "just depend" Something I have read is that they can Heat Soak quicker so if your gearing is not just right the power falls off quickly.

I am using the Team Scream motors. I started USGT with the original SS stator based motor and then got The One. There is a very noticeable increase in power and top end with The One. It is several points lower in IR than the previous version. I have been accused of running "boost" with this motor. Final tuning for The One is by comparing end of run laps to the initial run laps and set for no more than .2 second drop-off. The temperature this takes place at is way under harmful levels.

Have you driven a Trinity 24K certified? I am asking because that is what I was thinking of eventually upgrading to

They are quite flat compared to Fantom TSR and Motiv. I have seen it first hand. They are just not as fast as the other 3

This ^ I have a 24K 21.5 that just feels flat like mentioned

Correct, & I believe some refer to their new winds as a Thin, Short Stack, & at the moment, the companies I can recall that are using them, are TSR(The One), Fantom(their FR-1v2), Team Powers(Actinium v2) & Motiv(MC2, or M-Code 2). But before you bolt in the hot motor of the month, it's best to focus more at first on car setup & driving. And for that, I think it's a good idea to have something cheap but decent to practice with & have as a backup, like the Trackstar ROAR-legal V2's, they're a surprisingly stout motor, at a bargain price(you can get one from around $46 or so). Use the budget motor at first until you feel that you're driving well enough that the motor is actually holding you back, then you bolt in the big gun & unleash the beast....

not to mention Trinity charges big money for motors that are no more likely to be top-level than motors you can buy for half the price. With Trinity(unless you're sponsored by them) you're just buying the name, not worth it IMHO. With sellers like Fantom, Team Scream, Motiv, etc., you're getting a motor that HAS been given the personal touch by racers like us, they don't rely on the name for sales, they rely on performance & word of mouth, so ALL of their motors have to be as good as they can make them. I have MUCH more trust in them than in any big-name brands....

The top drivers at our local track are all running TSR motors in USGT. I'm going to see if a Fantom or MC2 can close the gap. The MC2 is significantly less expensive than TSR or Fantom but are hard to get a hold of. IMO "Short Stack" has become more of a marketing term than a measure of the motor's actual performance. I believe rotor strength has also improved recently but no one seems to mention it.

The new Motiv is definitely stout and would be good competition for the TSR. I haven't tried the Actinium yet but I think it also would stack up quite nicely as an alternative from what I hear.

My choice is still the TSR for USGT.

One think to keep in mind as was mentioned in a previous post is that skill and setup should be in check first and foremost prior to dropping in the latest hot motor. The 21.5's today are faster than the 17.5's of the past (IMO) so the speeds they turn can lead to spectacular damage if not accompanied by skill and handling.

I think too often people buy straight line speed but end up with worse overall results. A hot motor will be guaranteed to expose and exaggerate a poor handling car, so beware!

Yes, I have the 17.5 version of the Actinium v2, tried it in both my 1/12 scale & my 2WD buggy(on both clay & carpet), & I'm pretty impressed with it so far, strong on both bottom & top end, & does so with less can timing than any of my previous motors(around 5-10 degrees less timing). It's a stout little monster....

I agree; I've been very happy with my Team Powers Actinium V2 motors. The 21.5 was the same speed on the straight as the TSR The One that costs much more and has a lead time of many weeks.
The dyno showed that the 17.5 was best at 46 dsgrees and the 21.5 was best at 47 degrees.

When you say dyno do you mean motor analyzer?
