Best brushless system for TRF501x
 

Can anyone advise on the best brushless system for TRF501x?

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.

if you want to run one without a fan, nosram/lrp is probably the way to go

ive heard of people running novak ones without the fans, but they get really hot.

i recommend the Nosram/LRP comp 07 ones,

Thanks for your suggestions.

Do you know why they don't get so hot compared to the GTB?

And, sorry for the big ask, but can you point me at the exact model you refer to? There are quite a few LRP Spheres and Nosrams (Touring car ones etc).

This one, top speedo i have one in my xx4 and there ace.

And if you want a motor go for an orion vortex they have a sinitered rotor and they are a very very good motor.

I used to run a nosram istc speedo and storm evo 6.5 motor in my tamiya, all fitted neatly and worked a dream with no overheating(fan on speedo tho)
speedo opposite motor, as you dont need to move the brushless!!
Hope this helps

my LRP system is awsome now ive got it underwraps with the settings on my car sorted, its alot more durable. where did you get youre vortex from ash ? and how much was it... also what ranges and meusrements are they come in IE .. 4.5 5.5 6.5 such and such..

i want somthing not too fast for my B4FT but somthing that will give a little speed if you know what i mean ;)

I was thinking of this:

and this:

Is this rotor in the X-11 already sintered? If not, any ideas where I can get one?

What do you think?

Go for the GTB, seems to be the reliable choice aswell as a great performer.

You don't have to run the supplied 30mm fan on the GTB, instead you can mount it on the chassis blowing accross the fins - this is what I have done with a 25mm fan and i creates loads of space - and with the fan wired direct to 7.2v it stays very cool indeed.... ultimate in reliability ;)

Could you show me a pic of how its all mounted Chris. Sorry if this is a big ask but I'm new to this brushless malarkey and the TRF is as tight as a gnats chuff inside! ;)

yeh, that sphere is the one to go for, same as the nosram matrix [just really a choice of colour :D] great speed controllers, i own two. in my 2wd i dont have a fan, in my 4wd i do, but i dont really think its needed.

ok enough is enough, the guy is looking at shelling out up to £200, so its quite important to him that he gets good advice. so telling him to buy a particular speedo and motor when you have zero knowledge of any other system and zero knowledge of the car he is putting it in doesnt really help does it. you could argue for instance that chris long doesn't know about any other system than the GTB, however i know that chris long is an experienced racer who happened to make the A at a national on saturday.

so ashley lets ask you a few questions, the orion vortex is a good motor you say, what makes it better than a novak,lrp or others?, sintered rotor whats one of them then?, what particular motor from the vortex range shall i go for 4.5.5.5 etc. how much experience have you got and at what level with brushless? have you pushed neil cragg hard in qualifiying so giving your preferred brushless combo a good test or qualified in the bottom final with lots of DNF's?.

i am sorry to sound harsh and i am sure your advice is well intentioned, what you should have said is "i use XXX speedo with XXX motor in a XXX car and i find it very good its my first brushless system and i got it from XXX".

i do get annoyed when i see advice given to people who will act thinking it is good advice, when in reality its from a 10 year old who's only experience is running a tyco car around his bedroom.

(i am aware that ashley is not 10 and probably hasn't got a tyco)

So where is this going please? :eh?:

Credible options suggested so far have been (all to go into a TRF501X which is a very tight fit on the inside - soon to have a 87T spur installed):

• LRP Sphere 2007 with X11 motor (5.5)
• GTB system (5.5) with a 25mm fan instead of the 30mm one mounted on the side of the chassis

Thanks for everyones contributions so far.

Sorry it posted twice for some reason.

Admin can delete this if they want.

i have several team drivers running all the various brushless systems, lee martin uses novak, dump the fan that comes with it as all the drivers i know have lost blades in the first run. you would always be best to have the fan in its correct place on top however space is tight in the 501 so anywhere is better than nowhere. LRP/Nosram same speedo different colour. opinion amongst my F1 drivers (lee martin,kevin lee and truman) is the novak non sintered 5.5 is a little "softer" than the lrp/nosram equivalent, thats not a bad thing as it may suit your driving style better.

which is best? difficult question, i like the novak, big heatsink and fan, heat is always the issue, the new lrp TC with the fan is getting good feedback. to be honest if you bought any of the three systems you won't have made a bad choice.

a final point, it is very easy to get the gearing wrong and over heat, brushless is relatively new and the technology is developing, i have had several speedo's returned for warranty claims and you may too, so buy it in this country, i don't care if it is from me,dcracing or any other supplier, i know the dollar price is attractive and if your on a budget it may be the only way for you to get one but if possible buy in this country.

Well said. ( novak, ahem )

Thanks very much...that's very helpful.

Cheers.

Firstly I am biased towards the Novak, but with the greatest impartiality I can give I really do think it's the most robust system, both motor and speedo. I acknowledge the 'soft' comment above though.

A sintered motor is not only more tolerant of overgearing on the track, but is MUCH less likely to have the magnetic field strength damaged by overgearing.

I have seen a fair few std Novak fans break, mine is still on the original one in the 2wd, though the X6 shell offers it massive protection. You can lower the std fan height by taking the plastic spacers out too for about 4mm lowering. You can replace it with any other fan though. I know someone using the 3 racing 30mm fan (about £5 I think) and I use a 25mm fan in my 4ed withoug any heating issues (in fact my 4wd runs cooler than my 2wd)

Err might as well pay £10 extra and get the latest version.

Theres also the LRP version too, they are identical.

Russ,

Nosram / LRP has the advantage of being smaller and hence a bit easier to install in a 4wd.

Novak has the advantage that their availability seems a little better and the big heatsink definately helps.

For the Nosram / LRP you need to ensure you get one marked up as 2007 spec as for a few extra bucks your getting improved reliabilty.

I originally was going to run Nosram / LRP but just couldn't get my hands on a 2007 spec at short notice so went for Novak.

I was able to shoe-horn the Novak into the Lazer (another car tight on space), with the spacers from the fan removed the speedo fits under the top deck but the other edge rubs the shell, so the fan got relocated to be nearby the speedo. If it thermals in the hotter weather I'll get a new shell and cut it 5mm up from the trim line to allow more space inside. Also you can get slim line fans. The Novak fan is poo because the blades protrude out side the body of the fan so are very vulnerable to damage. The fan is easily replaced as it terminates on a standard connector.

3 of us all ran brushless lazers, 2 Nosram / LRP (heatsink, no fans), 1 Novak (fan relocated) all on equivalent motors and the Novak came off the coolest when probed. But not a lot in it.

The only problem I suffered was the car was lacking a bit in bottom end grunt, although the newer sintered rotors are supposed to improve this.

So my advice would be...

Buy a combo deal of motor and speedo as it saves a few £££, make sure its new spec (2007spec for LRP/NOSRAM , ribbed can motor for Novak)

Buy in the UK to ensure validity of warranty.

Performance wise all systems seem very, very close, but remember you can run different manufacturers of motors with different speedos.

If you can't fit a fan on the speedo, put one in the car somewhere to ensure you have some airflow.

Make sure you have somewhere sensible to put the receiver, avoid having it very close to the motor, and if you have to put it on the top deck make sure its not over the area of the motor.

Ok then the reason for my argumet is this is my first brushless system. The advatages of the vortex are it has sinitered rotor it has a built in fan for cooling and i have picked up other people's cars with the nosram and lrp and novak motors in and they are really really boiling my vortex gets warm but there motors are untouchable. mine i can hold my finger on for a good 20 seconds easily. And its a really smooth and torque motor.

A:)

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.

:) Garry D.

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.

A

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

lmao !


that sounds soo funny for all the wrong reasons :D :D :D :D :D :D

LMAO:D :D

Im not into that sort of thing chris.

A:D :o

or if you belly up for a while :D

:) 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.:)

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.

AND FROM POST LAST WEEK

need i say anymore ???

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 :wtf:

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

And??????????????

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

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.

A

Thats a rather short sighted statement.

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!
