Kenneth I just turn my epa on my throttle down when Im running the 3.5 motor and use the profiles in the sphere comp to control the aggressiveness of the throttle input, you cant gear it to high or it will thermal.

There are a few major diffrences:
1. The sintered magnet is WAY stronger magnetically so the motors overall power output is higher. They also have a much higher tolerance for heat so they retain their strength indefinatly.
2. The sintered magnet is WAY stronger physically so there are no issues with shattering rotors at high rpm.
3. The sintered magnet motors require lower gear ratios that are easier to accomplish in current low internal drive ratio sedans.
4. You run much less drag brake with the sintered rotor since the cogging is much stronger. This keep your speedo cooler.
5. The brakes are insanely strong so you have to reduce your radio's brake endpoint to limit the ultimate braking force. This also keep your speedo cooler.
There are cetainly applications where the bonded magnet is better like 1/12th and Off Road. The load in those applications are lower and smooth power delivery is very important.

I am no Hara or Moore - and don't like a car too quick in mod (sounds crazy) but want to be smooth and consistent. I also want to last with plenty to spare using 5cell.
Just trying to understand these numbers. Does 4.5 mean it is quicker than 5.5 and 6.5 etc, or just a different application? I note that LRP state the 4.5 (sintered magnet) has a lower RPM than the 5.5 (bonded magnet).
With brushed ut was easy 5 turn quicker than 7 etc, but greater stress on car and batteries and tyres etc.
Therefore will different brushless motor manufacturers numbers mean different things?
Sorry to sound dumb.
Thanks

my understanding is that you double the number of turns on a brushless motor rating to get the brushed equivelent. ie. 4.5 brushless is like a 9T brushed and a 8.5 brushless would peform like a 17T brushed. Lower turn = more rpm and avail hp with lower torque and more amp draw.

Will lrp sphere competition 2007 edition work with a 3.5t motor?Or will i need the tc spec for this kind of motor?(a bit confused about "over 3,5")

Some TC specs especially nosrams still have problems and don't work right with 3,5 or 4,5 motors , but nosrams/LRP 2007 works more than ok with 3,5 vortex , as you said nnick with heatsink and fan but works

HELP!
Does anyone know where one can get their hands on a TC Spec?!?! Jeez, these things are sooooooo hard to come by! everywhere i look they're not available!
i need one badly for an upcoming big race! HELP!!!
PS. will the X11 work with a Novak GTB speedo? will it be a direct fit - meaning will the sensor wires plug of the X11 straight into the GTB or wil i need some sort of adapter??

The GTB sensor wires will be a direct fit--no adapters. The GTB is rated 3.5T and above.
Additionally, all Novak motors are protected against thermal overload when used with a Novak esc

I have not yet heardt from any problems of these kinds with our TC-Spec speedos.

It's not a rumor its an experience!!
greek distributor received some TC specs friday before the race so 3 drivers including me , we tested it saturday before the race!!!
Al the three we had the same problem , if the rotor stoped at a specific position then you had to push the car so it could start and then when you pulled the trigger full back something like glitching was happening and the motor didn't work normaally.
the three of us raced at sunday with nosram 2007 and 3,5T motors without problems for the speedo/motor.
