need to read the entire thread then dont i.. sigh lazyness :p

So do you guys reckon it's worth investing in a brushless system now? i'm looking at buying some new racing kit for the new season and was going to buy a new esc and checkpoint but i'm tempted now by the brushless..

How long do you think it'll be competitive for though? will i be able to run it two or more years and not be left behind by newer faster setups? I'd of thought that the 4.5 novak would be the fastest you'd ever want for offroad....!

DCM 25-04-2006 10:13 AM

if it is a sensored system, then as long as the motor got the Hall connector on it, then in theory it should work, just watch the ESC temperatures.

Brushless is a fuss free system, just remember, it will still need cleaning out inside, just no skimming or brushes.

craigosh 25-04-2006 10:37 AM

well it getting more appealing the more i look at it really.. I'm useless when it comes to getting motors serviced, hate soldering brushes and dont think i've ever skimmed a motor...!!! just need to decide if my old dynastorm will take the power from a brushless.. handles my 10x2 checkpoint fine though..

DCM 25-04-2006 10:43 AM

Ahh, your Dynastorm in the pics from Southport... ACE...

You just need to choose the motor with an 'equivalent' rating to a 10x2 to be honest.... and go from there, just ensure the motor is on the Brushless list on the BRCA site.

craigosh 25-04-2006 11:32 AM

eh? what pics??? not seen em...

looks like it'll be either the lrp/nosram 3 star or novak gtb 6.5.
Any idea if the gtb will fit in the dark impact?

Northy 25-04-2006 11:49 AM

I'd say either of those would be a good choice. I've got a Novak 6.5 for indoors and a 5.5 for outdoors in da Pred! :D

DCM 25-04-2006 12:17 PM

yes, brushless fits the DI... I think I have seen pics of a Novak system in there.

Rob 16-05-2006 07:15 PM

To revive this topic again.

I'm going to buy the LRP Sphere Competition and 4 star motor. This is mainly for my 1/12th car (legal for nationals now :D).

I also want to use it in my 2WD B4. Should I just set the punch to the lowest low grip setting? I'm only really going to run at Bury Metro, Southport & Batley in regionals, club days.

Also has anyone tried the Sphere Comp with a brushed motor? Wondered what it would be like with a 19t in my 1/12th to save swapping ESC's.

OldTimer 16-05-2006 07:31 PM

Rob, i have just installed the Sphere Comp in my 4wd tonight with the 3 star motor, hopefully have its 1st run this weekend at the mid-west regional :) fits nice and the setup of the speedo is straight forward, but lots of wires.

From what i have been told the lowest punch setting is very good on low traction surfaces, almost like traction control. Would of been handy at the tiverton national if you could use brushless.

Rob 16-05-2006 07:33 PM

Would it probably be better to get a 4 star & 3 star? 4 star for 1/12 and 3 star for 2wd off road?

OldTimer 16-05-2006 07:46 PM

3 star is around a 9-10 turn brushed motor, not sure of the 4 star but i guess that should be good in the 1/12, i can tell you after sunday what the 3 star is like ;) but it would be good to have a couple of motors to switch between.

KingBob 17-05-2006 03:16 AM

Novak
 
I just recently dropped a Novak GTB with Velociti 6.5 Motor in my T4, absolutely flies. More efficient, more punch, and better runtimes than brushed.

Considering getting a 5.5 motor as well, might be a tad too much for a truck, the tracks here tend to be on the slippery side.

Maybe a 4.5 when i get my yokomo MR4 BX :D

sefton 17-05-2006 06:40 AM

I've got the GTB 6.5 in my B4, your welcome to come & have a look next time I'm at Bury!

Craig.

Northy 17-05-2006 07:07 AM

I'd have thought a 6.5 would be good in a 2wd, my 5.5 was awesome in the X10 till the speedo went pop. :(

Well I was thinking about getting the novak 6.5 (or an LRP's one) for my MR4 BX, thought 4.5 was meant for touring cars... be way too much for off road would it not? Or is there no such thing as way too much?

Hi Rob,

4-star motor in a 2WD would be fine... if you can drive 12th cars you will have enough throttle control to be able to drive a 2WD with a 4-star motor in it. geared right it will be pretty silly fast though :) I almost destroyed my 2WD trying it out in the street, mid-speed power wheelie onto its back.

the low traction setting is really for where there is very little traction at all, just the setting above that for most off-road applications.

Sphere comp running brushed motors is fine, better than most brushed speedos actually, the comp version it brushed/burshless auto sensing to no need to change any settings, except maybe 'auto brake' which you might run on a brushless motor to make it feel like a brushed motor, but turn it off when using a brushed motor, else it will be locking the rear wheel off power.

a 4-star is supoed to be similar to a 7 turn brushed motor.

If you were to buy an extra brushless motor for off-road, then the 3-star would be a good bet, it has a wider power band than the 4-star, though it does not rev as high.

Hope that helps, its also useful to turn off the 'LiPo' mode, we don't need low voltage protection using nmhi cells, don't risk having it on.

OldTimer 17-05-2006 08:13 AM

You never go to fast :D, the 3 star or equivilant novak would be about right for the Yok.

KingBob 17-05-2006 09:13 AM

Being realistic, i think the 55. should be nice in the Yokomo... the 6.5 is just right in the T4. Though when running the Orion 7.4V 4800mah Lipo it's a bit nuts. Pity I can't shoehorn one of those into a yokomo!

jimmy 17-05-2006 09:20 AM

Some of the tracks cry out for mega speed, Ive almost fallen asleep on a straight at durham n.e regional. So, get the fastest possible!! :)

Rob 17-05-2006 01:01 PM

OK I'm just going to get the 4 star to start off with, If it's too fast then I can always get the 3 star later.

What pinion would you suggest starting with Chris on a B4 with stock spur.

OldTimer 17-05-2006 01:07 PM

Rob, i think the 4 star if it is a lower wind than the 3 star (9t-10t brushed) will be a bit to wild for a B4, maybe start the other way around with a 3 star.

Rob 17-05-2006 01:19 PM

I need the 4 star for my 1/12th. Maximum speed and runtime :)

I'll see how it goes, if it's too fast for the B4 then I'll stick with brushed in that for the moment.

sefton 17-05-2006 01:20 PM

Ive got the gtb 6.5 and I gear my b4 with a 81 spur and 18 pinion.

Rob, whatever the overall ratio states in the manual for the 4-star start with that, it wont be far wrong.

Here are a couple of quick photos of the Sphere Comp with 3 star motor fitted in the Slim4 4wd.

What's that in the background? :confused: :D

looks like an old skool JRX-pro, my first Losi.

Northy 17-05-2006 09:32 PM

Not to me it doesn't! :)

Stu 17-05-2006 09:34 PM

G, what about the JRX that's in ya mates shed?
What's crack?

DCM 17-05-2006 09:38 PM

Doughty, fibber... we knoooooooooooooooow.... roflol

Northy 17-05-2006 09:40 PM

Stu,

Its actually a Junior 2, and I've asked him if he fancies parting with it (but it's his brothers really).

Nearly got the Gold Tub RC10 back together. :D

PaulRotheram 17-05-2006 10:20 PM

hmm.. i might have to try one of these brushlesses.. quite a few are starting to get them :confused:

Chris Doughty 18-05-2006 06:46 AM

mine is ace, I might run my sphere comp with a brushed motor at southport.

sefton 18-05-2006 07:09 AM

At the moment my b4 has a gtb 6.5 with a 81 spur & 18 pinion (as suggested by novak). But it just isnt half as quick as I imagined it would be.

what gearing would you guys recomend?

Craig.

Rob 18-05-2006 07:42 AM

Isn't the 6.5 suppose to be the equilivant of a 10 turn? I gear my 10x2 motor about 20 or 21 pinion. I used 21 at Bury on Sunday and was just getting warm.

sefton 18-05-2006 08:06 AM

Aparently you should use about 2 teeth lower on the pinion with brushless.

Chris Doughty 18-05-2006 08:08 AM

I agree with that, I have found that 'equivilant' brushless versions of the same motor need to be 2-3 teeth lower (in a Losi)

sefton 18-05-2006 08:14 AM

Whats the best way to make it faster then?
