LRP Vs Novak Brushless for stock
#16

My only "proof" is stuff I've read on rctech and stuff I've seen at the track. The latter is purely anecdotal evidence, but the former could be viewed as empirical proof given the sheer quantity of posts dedicated to the topic. Just do a search of this forum if you don't believe me.

I've been using a 2006 LRP Sphere Comp and a 2007 LRP Sphere Comp for quite some time. Both of them work flawlessly. The 2007 LRP TC Spec is currently the best speedo on the market right now. I'd buy it with the new LRP 13.5 and also pick up an optional sintered rotor. If your track only allows Novak 13.5's, get a LRP TC Spec with a Novak 13.5 instead.....

Stock equivalent racing:
In the beginning Novak as far as racing application they did have a thermal problem.
There problem was the racers were over gearing and running outrageous run times on a bonded rotor. They would thermal after the magnet had been over heated about 3 or 4 times. All rotor thermal issues.
Novak addressed the problem with the sintered rotor. And the rotor temp problems went away. It even allowed the esc to be run without the fan.
Modified racing:
The Esc will thermal. Over gearing will cause the Esc to over heat. And the rotor in some cases.
Keep the gearing to a reasonable ratio and that problem is solved. No thermal problems.
The problem has never been Novak.
Spend your RC dollars wisely. Buy Novak products. When it comes to RC electronics,,,,Novak is paving the way.

I noticed that Tower had them in stock for a couple of days last week and now they are out of stock. I backordered mine at the LHS and it arrived last week. I'd backorder one before AE/LRP has a 2 - 3 month 13.5 "dry spell".

The vast majority of GTB thermal shutdowns that you see or read about are due to the motor temperature. The LRP speedos don't have a motor cutoff feature, so it is a good idea to have a temp-gun on-hand to make sure your motor stays in a safe temp range.
Novak has some bad press dating back to when all the motors had bonded rotors...the bonded rotors ran hotter and the GTB would shut down to protect the motor - but even though the ESC shut the system down, the magnets in the motor were still damaged, causing them to heat up faster and shut down even more often in later runs.
All in all, heat shouldn't really be a determinant in your decision - if you want a "LRP-spec" thermal shutdown feature, all you have to do is remove the blue wire from the sensor plug. I'm pretty sure this will void Novak's warranty for the motor...AFAIK, Novak supports the use of other brands of motors with their ESC, but they do not support the use of other ESC's with their motors (even though they work fine) - if a Novak motor is sent in with significant heat damage, Novak CS could easily make the determination that it wasn't used with their ESC.

Hi all
Firstly, thanks for all the replies.
Next, how do I tell if the one that I purchase has the new rotor? I have been looking on tower hobbies website and they have the packages available at present at pretty good prices.
thanks
