Best brushless system for TRF501x

[xx4-nutter]

the thing is ash if you hammer a car for 5 mins or say 3 mins its going to get hot, if you drive slowish which maybe youre ability the car isnt really going to get warm, im not diggin at you bud but this could be the reason why my freind.


if you are covering a massive distance in laps in a race its going to get warm, if you are not then its gonna stay relativly cool.

even when i mess about at club i can run the car for 15 minutes + and it still doesnt get really hot. The motor runs really cool.

And its a really smooth and torque motor.

Hey Ash, I bet I could get your motor hot...

[ashleyb4]

LMAO

Im not into that sort of thing chris.

This is purely my personal experience as these our are first brushless systems. Both my son & I run the Nosram Matrix Evolution 2007 version speedo's, mine with an LRP X11 6.5 & his with the Nosram Storm 6.5. Mines fitted in a HB Cyclone D4, has the factory heatsink and only the roof vent cut out & his is in a Ttech Predator XRS, no heatsink fitted and both side vents cut out (this is much tighter for space than the D4).
So far we've had no overheating issues although I shall be doing another shell with vents cut in the front for the summer. We're both running overall gearing around 12.5. I shall also be ordering the fans from the TC version just in case.
I appreciate what Modelimages is saying and we are only club racers doing the odd away meeting but so far we've been very happy with what we've bought.
We bought ours from our LHS as we know that if we do have any problems they'll support us if the need arises.

I'm really thinking about size overall and how it will fit in the shell.

Would prefer one without a fan, but if they run hot would definitely need one I suppose. Would like to avoid butchering the shell just to fit the GTB's fan in.

Do the LRP / Nosram ones ones without fan run cooler than the GTB?

Can anyone advise?

Thanks.

Best to check this thread out http://www.oople.com/forums/showthread.php?t=1929. Looks like the GTB install is possible but gets a bit messy. I'm kind of wishing I had the LRP instead... But I'll give the GTB a go when I get around to it. RIght now I'm pretty happy with my brushed 11x2 on a small/med track.

Although I havn't had experience with the Novak speedo's, from what I have seen it looks like the LRP/Nosram is the better speedo and Novak are the best motors.
I've had an LRP 2007 and Nosram ISTC, both have been run in the BJ4 with no heat problems at all. The LRP was run with just a heatsink and the Nosram with it's built in heatsink + fan.

Motor wise I've only ever had an LRP X11 5.5 in the BJ4 which has been faultless so far and nice and fast too.
In the 2wd I've run an X11 6.5 and borrowed Novak Sintered 6.5 and 7.5's. The LRP was definately faster and felt better to drive, but the Novak was much quieter and smoother.
There were a lot of people having problems with the LRP 6.5's rotors falling apart at Bury, me included which is what points me to try the Novak motors next. I don't understand why LRP are sticking to bonded magnets in the 5.5 and 6.5, sintered are more powerful, run cooler, more reliable and cost less to make

Remember I'm not supported by either LRP/Nosram or Novak so I'd like to think I'm not biased

well you bought a motor not really knowing that much about it ash , thats all ...
its one of the main features about that motor....

[ashleyb4]

I bought the motor because i have used orion brushed motors before and they are the best in the world. And because i had heard about people having problems with all the other motors so as the vortex was new and had been under development for a long time. I knew it would be good. And i was right its an amazing motor.

Thats a rather short sighted statement.

[Lee Martin]

yeh, how can you say tht???????????

no offence...but can you even tell the difference yet...as you are only running 19T's etc.......

and how do you kno that your cells are not shot away?

you cant really comment on a motor without trying everyone in the world. and im certain you havn't..........

ever even tried another brushless?

you CAN NOT say somethings the best without trying the rest!
