Guys we initally went with the Thunderpower (red case) 21.5 and then we picked up a Killshot (rpm version) 21.5 for our Tamiya mini's ( killshot went in the m03 and the tp went in the m05)
They seem to be evenly matched with the exception that the Killshot seems to run alittle hotter than
The Thunderpower. At a recent race we were talking with a driver that was putting down hotlaps that
Were real fast. He was running the R1 Wurks 21.5 and he had no complaints at all.

If last years nationals are anything to go by, you would have to say R1 Wurks, followed by Trinity D4.
I'd like to see some numbers on the R1 vs D4 and the express modified D4's as I'm looking for a replacement myself and they are on my short list. Can't find much on 21.5's

Running a 17.5 RX3 in my buggy, quite happy with it.

A motor you guys should consider that hasn't been mentioned yet. Is the Team Scream Racing 21.5. We have had many great result with people using them on large tracks (150x75 or larger). Some in Australia and some in the States. These tests were with the standard stator stacks, now that all the short stack motors are roar approved it will only get better. I went to snow birds this year, with my TSR 17.5 in my touring car (the short stack, essentially the same motor anyone would receive if they bought one from their site, (tolerances being the only difference)). It was stupid fast the whole run, with minimal drop off. I was pulling some down the back straight, and out of a couple of corners. I ended up finishing in the D main for stock (the motor and batteries were fantastic, that part wasn't holding me back for sure, the driver of the thing was haha!) We also offer some of the best customer service, and gearing advice until your 100% happy. If you would like to know any specifics of the motor (such as resistance, rotor strengths, or how we build/tune our motors for EACH individual application, please feel free to message me, of if you have any other questions).

I'm liking the plug idea on the speed passion motors.
Makes it quick and easy to change between 21.5 and 13.5 and even mod between races if you only have 1 car.
Or mod and 10.5 in 1/12th
Especially if your like me and hates soldering and doesn't want to do it every time you change a motor.
