Sounds good to me. I'm still waiting for that 1717 to come out :whistle:

Oh, and BTW,

The 1512(1.5Y) -1800, 1717(1Y) - 1700, 1518 (1Y) - 1800, and 1520(1Y) - 1650 should be available for purchase in a few days.

The "New" CC/Neus.

The CC/Neu rotors don't do D winds.

Oh, all right. But I really wanted those EXACT kv's! J/K, anything close will do!

This is assuming that the 4400 is going to respond the same as a 4.5. Which with 1/8 shaft was listed as 4800 kv. Then with the 5mm upgrade they changed it to 5000kv. Now they say with the 14mm rotor you can gear it up because of the lower kv and added torque.

That 4400 rotor was supposed to be horrible, your lucky it didn't blow. Mine was atleast the sintered 1/8th shaft.

If it was the 14mm rotor I wouldn't be scared to throw 5s at it. Novak did this to a stock 4.5 and broke 100mph in a street car, with their esc.

The 4.5 on 5S was run for what, one attempt (130 feet?) at a speed run?

The HV4400 is a 6.5 turn motor. From the original bonded rotor to the 12.3 (or so) sintered rotor takes the KV down to 3400. The 14MM rotor is supposed to drop the KV another 20%, taking the 6.5[HV4400] to 2720. That still seems high for 5S. I'd say go with a 7.5HV.

I've been running a 7.5HV on 3S in a CRT.5 (using a Havoc 3s) and it runs plenty fast.

MMP + Larger motor = Bad when used in the wrong setup, in 1/8th setups I'd use it only on 6s with lower KV motors when your peak power output is less than 2,000 watts (keep the amps down).

MMM + Small motor = OK. Small motor + big truck = bad. You won't hurt a motor or ESC by using an overkill ESC.

okay, thx dude!

How long is the 1518?

So is there any chance of a 60mmish motor based on your smaller motors? I really like the 2 pole motors for smaller applications, where the higher torque is not needed. A fancy little sensor plug could be handy also, :) but not really necessary.

Huzzar...

WHOA what's the max voltage on that 1518?

I imagine that at 1800 KV it would be 5/6s for normal use and up to 8s for more extreme use.

Here's a pic of my new light weight setup, I'll be racing it this weekend to try it out. It comes in at 6lbs and 11.9ozs with out the body. I'm running a 1450kv 1509 tekno neu on 6cell 2500mah packs. With this same setup I can get 14 mins with the Mamba Monster esc. I'll see how it does with the MMax pro.

I must be missing something ...I don't see how long it is (in mm) will it fit a E-Revo?

Ah- imagination required, sorry.

It should fit just fine, may just have to fettle the rear shock tower a little for clearance. The 1518 is only about 3-5mm longer than the 1515 based on the comparsion of the 1520/1518/1512 in the photo above- if you take a look at the birdseye views of the BL erevo you get a good idea of how much space is available- one of the little brace thingies might need a notch cut into it, but nothing drastic realy:

Im sure dimensions will be posted when the new motors are put up for sale in the next few days or so- check the CC website at that time.
