Update:

I just received the 'Darkside rotor' 3.4 motor from DriftKingShop. I'll hopefully have some results on this motor soon.

I'll also be getting the 'Phast Motor' from RCMod soon as well.

The Multi-Cell tests is a definite must-do, good call TypeZer0.

Maybe you can add an efficiency column to the chart with the RATIO of the MAX current to MIN current. This could be really useful for multi-cell bits, I believe, because more efficient motors perform better with multiple cells. In this case, the 2.6 rules!

If a motor is doing NO work, than 100% of the power is converted to heat. This can explain why motors get so warm under no load. I think the maximum heat produced is I^2*R,
where R is the armature resistance and I is the NO LOAD current. Since the current is directly proportional the the voltage, a more efficient motor can run at a higher voltage before overheating.

This is good because the frequency (rpm) is directly proportional to the voltage. Please don't bite my head off if that's not what the tests say... that's just what my physics text book says!

By the way, your idea that current = torque is verified in my physics book too.

Hard-wired motors should work exactly the same. Sometimes the contact between the motor and the motor clip isn't very good (high resistance), so hard-wiring is juts a way to ensure that you don't have this problem. This is one of those mods where I gotta say... Don't fix it if it ain't broke.

(And of course, if it is broke... ya know)

umm thats kinda funny how the formula 34 out preforms r-spec and it has more torqe but the r-spec has a new version and its cheaper so i think ill buy another r-spec

Hey Namuna, did you test out the new NOS Express for ZIP ZAPS?

For the folks that keep asking if I've tested a certain motor or request that I do...As I've said in the beginning, I've test ONLY the motors that I have and anything after that are Motors sent to me by a Retailer/Manufacturer for testing.

At this point I've got PLENTY enough motors and have NO incentive to spend my own money to buy anymore.

If there's a motor I haven't tested and you want to see results on (like the Perfection 3.8 or ZZ NOS Express) I'd suggest maybe contacting the manufacturer or reseller and pointing them my way to send 'test' motors for me to get results on.

- Received the 'Darkside Rotor 3.4' from DriftKingShop.
- Should soon be receiving the 'Phast' motor from RCMod soon
- Ordered an 'Angle Finder' for precise measurment when I do the incline tests.

I notice that the lower rated motors work better in my dual and triple cells. Is there any particular reason for this? Also, while we're on the subject, what's the best motor for dual cell rides ? I currently am using the zz red 2.1 in my mult-cell cars. BTW. I've said this before, but those tests are awsome.......JD

I too am currently running a 2.1 in my daul ZZ, i tried a TRC 2.8... but that things got sooo much torque that it would just fishtail like mad! So I've found the 2.1 to be my best choice right now too.

And yeah Namuna's the man when it comes to all this techno gobbly-gook, he brings the info you didn't even know you wanted to know!

Nope, I haven't touched the numbers.

I'm also using a 2.1 motor in my hybrid dual cell MS Pro/Zip Zap. I tried faster motors, but had problems. The boosted speed would be very fast with the faster motor, but the unboosted speed would be slower than the 2.1. It's as if the motors display different properties with different voltages run through them.

the formula 34 rpm was higher than the r-spec before so if you didnt tiny did cause he didnt want that to get out

Results of the r-spec may have changed with the replacement of the original by V2.0... just a guess *shrug*
