I went from a Tacon 3660 540L 4000kv motor to the Novak 550 6.5 and it is gutless comparatively. Going by feel I'd say the tacon has more power on 2s vs the novak on 3s. I expected a drop in power due to the KV rating but WOW. I am not comparing top speed geared the same(lower KV) but the torque is nonexistent on the ballistic motor.

An analogy is the tacon would flip over easily on 3s where the Novak struggles to wheelie on the same setup(center diff/120k fluid). I expected a loss of top speed due to KV but didn't expect to have so little torque vs the tacon.

Temps are getting up there I had to cut the run short on 3s due to temps(165 and climbing). The tacon with the 4000kv put out less heat in a similar amount of time and the reason I bought the novak is for the cooler temps. Geared the same it gets crazy hot.

Gearing is 17/54 on a slash 4x4.

I have it hooked up to a totally new system(MMP).

Any ideas before I put the tacon back in?

Are the motor wires hooked up correctly? A-a b-b c-c ? Sometimes if hooked up wrong you will lose power. You should also be able to go way up on your pinion. 550 motors have way more torque than a 540 so you need to hear for top end not bottom. Especially that 6.5. Check esc settings also make sure power is turned up accordingly.

Punch is up,can't pinion up as the motor is already hot.

The motor wires are matched. I'm going to put the tacon back in and sell it.

It was the MMP causing problems.

My tacon motor is consideribly slower than with the Brushless hobbies 120a esc.

I have the punch set to max but dont have a castle link.

Is the MMP weaker than the BH120a esc?

I reset with castle link and it illeviated the punch problems with the tacon.

The ballistic 6.5 is still too slow for my liking.

I am going to try running sensored only mode vs smart sense and see if that helps.

Here is a Novak chart, even though it is a 550 motor you dropped from 4000 kv to 3400 kv.

The kv is your rpm at 1 volt.

This is why you have to gear up on lower kv motors to still get the top speed. 550 motors have way more torque than a 540 assuming the tacon is a 2 pole like the Novak. Ive ran a 2650 castle motor in my scte on 2s with 25 pinion and it was so fast. Way faster than my tekin sc4x 4600kv on 2s with 14 pinion. You will probably never get the Novak to work right with the MMP anyway. I could never get mine to work right. MMPs are crap IMO. I have resorted to just using mine in my SC with a 17.5 motor.

Have you checked the motor temp with a thermometer ?

I am not complaining about the speed at all I know it should be slower. I am complaining about the overall lack of power.

It has nothing near the same amount of torque the tacon has(think no wheelie vs flip over w/tacon).

It is a 550 motor vs a 550 tacon(3660).

After doing some research I couldn't find out how many poles the ballistic motor has but evidence is 2 pole sensored which isn't what I thought when I bought it.

I thought 4 pole sensored would balance out vs a 2 pole unsensored.

Motor temp on a hard bash with no heatsink has gotten up to 160 after about 3/4 of a pack. The top of the motor reads about 20-35 degrees hotter than the rest of it.

The tacon 3660 is a 540 motor. Both motors are 2 pole. The 550 2 poles you can advance timing all the way this will also help. 160 is not that hot for bashing either.

3660 is a 540L motor

540 can but longer same as a 550.

To the best of my knowledge a tacon 3660 is a 550 motor.

The ballistic is slightly longer than the 3660 but most of that length is due to the sensor.

Is this the motor you got? Specs are right here. http://www.hobbypartz.com/96m210-3660-4000kv-6t.html

Here is the specs for the Novak. http://www.hobbypartz.com/96m210-3660-4000kv-6t.html

They are about same size other than sensor board like you were saying. Even says watts on tacon are 1200 compared to 730 for Novak.

The big mistake here was on my part.

I bought the motor on this forum and didn't do enough research. I thought it was a 4 pole but turns out its an older design.

Probably a great racing motor and its very smooth but as a basher its not for me.

The tacon motor I have is a monster but it puts out too much heat for my liking(another reason I wanted a 4 pole).

I talked to some of our local racers, they feel only the 4.5 550 novak motor is good in all the 4x4 sc trucks & the 5.5 is ok in the ofna hyper10 & other lighter models & that the 6.5 is just not fast.

I concour.

I am going to keep the tacon for now and just let it run hot until it dies then replace with a tenshock motor.
