I'm planning on picking up an RC8Te or RC8Be (when it becomes available) and have come across a deal for a Novak HV pro 5.5T esc/motor combo and have no idea if that would be good for my application.

I checked out Novak's site and it seems likes it's designed for Monster Trucks and not 1/8 buggys/truggys.

Any of you guys have any experience with this?

Craig, from what I've been reading the HV's are great motors but just don't seem to have what it takes for 1/8th applications. They are a 550 size can so they have the same diameter as a 540 (1/10th) size can but are quite a bit longer, which gives great torque which is great for heavier 1/10th applications. You would probably be better served running a true 1/8th setup in either your truggy or buggy. I personally run an RC8B E and have a Tekin system in it, RX8/2050T8 on 4S. Another guy I race with has both the 8Be and 8Te and he is using RX8/1400 and RX81550 both on 6S.

You've got a lot of options but I don't think I would make the HV system one of them...just my $.02 and I am sure others will comment that are running this setup in an 1/8th scale application?

IMHO, the HV6.5 or HV7.5 would be suitable for a buggy (but not a truggy) with the addition of the 14MM tuning rotor. The ESC is still marginal for these applications and needs the fan running continuously. The true 1/8th scale brushless systems have fans but the fans rarely run because those ESCs can handle the current so much better.

That HV5.5 system would be great in a Slash 4X4.

Thanks guys, that's pretty much what I thought!

They are crap in any vehicle you put them in. DO NOT waste the money. They are $160-$175 for a reason.
They are extremely inefficient and will thermal even with the lightest gearing. Get a hobbywing setup long before giving your money to Novak.

The ESC is crap, not the motors. I used a 6.5 in an 8e and honestly liked it more on 3S than 4S. They are 4 pole motors so they will be more efficient than the cheaper Feigao motors which are about the same size.

If I was building an 1/8 buggy again I would use a 6.5 with a MMPro ESC. If you ran that geared conservatively, 11/45 or so, on 4S it would run really strong . It would be a bit lighter too than with a Tekin or a Castle system.

The HV series are not 4 pole motors.

Novak has not yet sold a 4 pole brushless motor. Maybe the new 1/8 motors will be 4 pole, but the current ones are not.

My bad. I just opened up a 5.5 HV and there are 3 poles. Still more efficient than a 2 pole motor.

I generally love Novak and they have great customer service, but their 1/8 scale speedos are not up to the level of the competition.

I think part of the issue is that they probably weren't designed for 1/8 racing. so we are trying to fit in a square peg in and round hole, so to speak.

As it sits right now based on what I have been reading and what I have experienced, The systems that interest me that are available for 1/8 electric are the Tekin RX8, Castle Mamba Monster, and the XERUN setups.

Your bad again: a 2 pole brushless motor has 3 stator poles. A 4 pole brushless motor has 12 stator poles. A brushless motor always has more stator poles than magnet poles otherwise the rotor won't rotate. The Novak is a 2-pole motor: Inrunner brushless motors are described by the number of magnetic poles of the rotor, not the stator. The Novak is a 2 pole motor.
