Go to Nick Adams Channel on YouTube to see the test of the R1 V21 13.5 and 17.5.

Well dang. Just got me a new 25.5 v16...

anyway. Playing with it on the motorlyzer, what are some numbers Iím looking for? Iíve set the time of to 50 as recommended, and using a battery at 7.8 volts. Iím getting 2010kv at 6.0 amps. That amperage seems high? First time really playing around with this for anything other than setting timing, so Iím not sure what to look for

thanks

bronson.

And for those that don't have 45 extra minutes to watch it here is a summary. The new R1 is the best production motor he's tested yet, with lowest stator resistance, higher efficiency, lightest, and best acceleration and power curves on his mini pro dyno. Also has shortened shaft, which makes it easier to fit in cars like the new xray that keep moving the motor closer to the middle of the car. The flat part on the rotor also extends all the way to the motor to give more/easier adjustment of pinion setting.

Hopefully the new version's sensor board won't fail on you on the 2nd run.

I've never had one fail, nor has anyone at my track. With that said, I know they stand by their warranty, and it appears the new sensor boards are a lot more accurate.

Any idea when the V21 will be available? Trying to get ready for the indoor season!

R1 1S battery is single sided. Can I drill through the plugs, and plug in from the other side? Safe to do that?

I think it is already available now in Europe...It will be fun to see these v21 motors at the track, specially with the new R1 10000mah hv lipo battery coming out soon.....

That's probably not the best idea

The best motor on the dyno provided you assume all motors want to be set to 6 amps unloaded prior to doing anything further (which they don't)

A lot of info Nick Adams provides is good, and informative but a lot of also nonsensical rambling, look kudos to him for having a youtube channel and the armchair critics that go with it, but you need to take his findings with a grain of salt and form your own opinion.

We all know that Nick and nobody else can be 100% right about everything all the time, but at least he can make it easier for most racers to know what to look for when evaluating new motors...Testing at different amp and timing parameters is encouraged, but he had to make a choice at some point. Maybe he might consider lowering the 6A value to further test his motors in the future....We'll see...

He's got a dyno. Set the timing to the value that produces peak power.

Yep the optimal timing spot is where a further in advancement of timing no longer increases rpm relative to amps, but increases amps by a value far greater than the rpm gain. It's different for each motor.

Saying "6A" or some other arbitrary figure is lazy and will give incorrect data and as a result flawed conclusions.
