Default Novak EX 8.5???

What is the difference between the Novak EX 8.5 and the other Novak motors. I was thinking about getting one to run in the mod class. They are cheaper than the others but are they as good?

The EX motors use less watts, have smaller bearings, do not use sintered magents (like the SS Pro does), and are a little bit heavier (6.73 oz compared to 6.61 oz).

Theyre alright. I have a couple. I usually run them when there isnt a whole bunch of bite because they are a little softer on the low end.

You should go onto Novak's web site (www.teamnovak.com) and look into a refurbished Ex 8.5 - they come with the upgrade kit of sintered rotor and big end-bell/ball bearings. That makes the run more like an SS8.5 rather than Ex8.5 in stock form. I'm running a 10.5 EX with the upgrade and it's noticeably faster than the 10.5 Ex stock. You should be fine with 8.5 with upgrade in the mod classes.

It would be like buying an SS - yes. However, it's at a lower price - with the new endbell and sintered motor installed - they'll perform like the SS for $40. It's effectively a "new" motor for half the retail cost of an SS.

Looking at the web site - however, it looks like a RMF EX 8.5 isn't there. They have 10.5 and 13.5 which have the upgrades. You know, the best bet may be the SS 8.5 over the Ex because of the higher Kv rating.

http://www.teamnovak.com/products/br...spec_chart.htm

New SS 8.5: $79
RMF SS 8.5: $55 (which is a good option too)
RMF Vel 7.5: $40 (would be good for Mod Buggy)
RMF Ex 10.5: $40 (on a smaller, twisty track, would be fine)

Unless you're running on a really large track or one that needs an insane amount of power to clear a tough obstacle you'll probably find the 10.5 is plenty of motor for a 2wd buggy. Use a good lipo and gear it really tall, they pull a lot of gear.
