Novak Brushless 5.5 or 6.5??
 

i'm new in BJ4, i want to know 5.5 or 6.5 which one is suitable in BJ4? is it 5.5 too powerful? and what's the teeth of pinion you are using?

You can never have too much power, if you can control your left thumb;)

The 5.5 seems to be the option most go for in 4wd, but depending on your level of skill you may be quicker wth a 6.5.

If you can control your left index finger ;) hahaha

I have the LRP 6.5 in my car, and I only switch over to the 5.5 for the larger tracks.

Hey Lee, I only run a 6.5 in my Pred :mad: :mad: :mad: :mad:

G

I still use brushed;)

Good old fashioned checkpoint 10x2

Proper retro:D

I'm running a Novak GTB/4.5 in my BJ4 and I'm loving it but I am right on the limit of my Batt 4000 cells. Had to drop to 14/78 from 15 at the last meeting to guarantee the finish :( . Still plenty fast enough though :)

Regards,
Jon.

I run an LRP 5.5 in my BJ4 which is pretty spot on, I can't imagine really wanting a 6.5; just don't push the stick/trigger as far ;)

The Novak motors are slightly slower turn for turn compared to the LRP's so a 5.5 Novak is probably somewhere between an LRP 5.5 and 6.5, go for the 5.5 :)

i just got a bj4 myself.have a novak 5.5 and 6.5 any idea of what pinions to use with these motors?cheers for any help

what pinion you runing with the 5.5 lrp rich

cheers paul

I'm running the Novak 5.5 on a 17 and kit spur (78t)

15 or 16 depending on the track with an 81 spur (the kit spur is 78) :)

thanks:)

Do you use the stock rotor (bounded) or the option one (sinterred) ?

Thanks

Rich uses the novak sintered motors.

Are you sure??

Which rich? Rich Lowe. It is just that when ever i have seen his car he has been running a lrp x11 5.5 motor. Well he could have put a novak sintered rotor in it whithout out us all knowing.;)

I was pitting with him on Sat and i'm 100% certain he runs LRP cans and rotors. My 5.5 died and we had a conversation about rotors this is why i'm asking.

Bit off topic but, did you make it to York in time Neil!!

..........and what is Morphosis Automotive Artwork???

You are correct sorry chaps, Rich advised me to get novak sintered, sorry i stand corrected.

Hi Simon, yes we made it to York in time although we were a little tired, Richards eyes had turned red he was that shattered!

Morphosis is Simon major who sprays my shells along with a few others. He's very quick, 3-4 day turnaround although i think he managed to spray Gregg Williams shell in 24 hours as he needed it for a National. His prices are superb too.


Lee, thanks for letting me have a go with your car as well.:)

I wanted to give it to you for the last final but i got snee`d in leg 2, let me know where your racing next and ill do 2wd and you can run mine

Top man thats really good of you. I can't believe Snee butchered someone.:D :D

I almost fell asleep a couple of times at the York meeting lol :D

LRP motors in both my cars at the moment, will be moving to Novak when funds allow (sticking with LRP/Nosram speedo's though) :)

I've just ordered a 4.5. Need a car for it to go in now...

4.5, you animal!!!

......BJ4's are good :p

I was running a borrowed 4.5 on Sat. as my 5.5 died, it was great fun just ask your dad!!

A BJ4 is an option they do seem to go well.:)

I wouldn`t swap mine for anything else on the market right now. The car is so easy to drive fast, it suits the smoother driver also.

I really like my XX4 but want to have a good run with a BJ4 and do a side by side test.

I currently have a bj4we and would quite like to see how well a xx4 goes compared to it. So maybe a little temparary swap maybe in order, depending on how each of us drives.:)

Er, i think i'll take up Lee's generous offer, thanks though.

And who is going to lend you there xx4 to try then:confused:

I would have to find a willing voulentier.:D But they would not be allowed to know how i have driven cars before.:rolleyes: So they wouldn't know how the car COULD end up, I emphesize the word COULD as it COULD happen. But not for definate.:)

Sorry about the spelling

I ran my Novak sintered 5.5 in the S4 (same transmission as BJ4) for the first time today at Oswestry and I am very pleased with it. I started with 16/78 and ended with 18/78 I still think it might have pulled a slightly bigger gear on the really long straight but to be honest it was quick enough for me.

As I understand it a sintered rotor runs 2/3 pinions higher than a bonded rotor.

i run a 7.5, my lap times are as fast as (or faster) than anyone here at my track who runs a 5.5

my straights are about 25meters (70 foot?)

end of day its down to driver and tires....

what about a 4.5?

I run a 7.5 in my xx4 ive driven a bj4 and i personally preffer the xx4 its seems smoother and more predicatable.

how come you are running novak motors rich???

A

B44 motor / gearing
 

Novak 5.5R with a sintered rotor upgrade. 16t Richardson Racing titanium pinion and 84t composite spur (stock AE), ceramic diff balls and ceramic bearings throughout.

Sintered rotor definitely gives more punch off the line and at mid-throttle -- typlical race conditions. Plus, it stops like a 10-cent crack whore picking up a penny with a little front finger push. Need to adjust the GTB to be 9% instead of 27% breaking.Top-end is perfectly in line, or faster with the R series motors. I have giant maxamps 5500 Lipo packs, so I get 20 min+ runtimes with all that hot motor. What I have to be especially careful about is balding my front tires too soon in the race. It's easy to do because the car just pulls and pulls. I might need to set my wing a little more agressively to conteract the front steerage. I'll be looking to upgrade the motor bearings to ceramic as soon as they're available -- LRP just announced them and I think the specs are the same for Novaks.

Couldn't be happier with the setup -- just have to drive consistently to optimize speed over uncontrollability.

Again, the sintered rotor is definitiely a cultured improvement for the 5.5R Novak. Your milage may vary. I can't imagine a faster motor in this car....

DX3R + digital HRC36965S Hitec servo, BJ4 carbon and alu steering kit, BJ4 center diffs; lundsford Ti everything.

Orion is where its at!!

I was very disappointed with the novak motors:(
