I have this 7.5 Novak Slydr system for about 4 years I think since it got out and have done its job really good no questions ask. But lately It started acting up. I've been having a lot of cogging with the accelerations to the point that it throttles high >low >high >low even though I have my finger steady on the throttle.

Like its got a sour throat that keeps on coughing.. You guys have any idea for a cure or had the same experience? I know a lot of people here had their novaks completely dead.. but this one is still alive and maybe it just needs a little TLC



FYI this has zero maintenance since it got out of the box lol

Hey Jay,

Not sure where the problem lies whether its a faulty esc or motor....on the motor side you can try and check the motor bearings for wear, a sticking bearing could be causing the irregular throttle response - they may just need a drop of oil or replacement. Also you can try opening up and just giving it a good clean inside with some compressed air....

the motor is 4 years old so i would imagine the motor could be pretty dirty considering the conditions we play in....hope that helps.

pity you dont live in the US as novak has a trade in program for old motors and esc's.... send them your old stuff and a few $$$ and the send you a new one...

i experience same problem with my ballistic & GTB

When i replace my ESC with Mamba Max my motor run perfectly again

try your motor with other ESC or your ESC with other motor then see which one has to be

replaced

Rebuild/Clean No. 1 solution...

Hi jay ..... search in youtube ... there's a vid there showing how to clean your brushless motor from charlie swangka of Novak

@paul Im sure its got dirt from alain, abudhabi and dubai in it lol I dont think warranty still applies for this old system.

@jon Im just waiting for Ians pm so I could get on with the testing

@bandit will do that as soon as i get home from work!

@strawb will search on that one just to make sure im doin everything right!

Hope everything goes well after the rebuild. Thanks all for the replies.

check your sensor connector, clean & degrease it very carefully - that is main fault point

inside ESC is pretty well sealed so dirt can't get in too easily


make sure your motor bearings haven't seized & u run until they collapse

all the Novaks i've seen used offroad the front bearing gets jammed very easy
and need to be cleaned regularly, otherwise buy gotta buy whole new front bell.
Some keep running with seized bearing and the rotor shaft wears down...

all external points cleaned and checked.. now to access the internals.. I have a full set of hexes that doesnt fit with the front screws .. another problem

and another thing.. were can i get a can of compressed air? enoc?

yes you can buy the can of compressed air in any petrol stations....

jay, bring it with you in area2 and get it sprayed with the high pressure air spray they use in cars

I have never seen cans of compressed air at a petrol station. But you will find it at a computer repair shop. Personally I believe that compressed air and bearings are not great together, all the air does is displace the dirt....to another place.
Disassemble and replace them where necessary. I have replaced the bearings in 2 of my EZrun motors and they never did anything near 4 years....

Get a decent socket set that covers the range in your motor.

I have a novak rooster ESC that just died on me, and it ticked me off that they were not prepared to replace it. It is in perfect working order APART from the fact that brakes dont work..

One reason for all of you guys to go brushed!!!!!

Old School!!!! My drifter and crawler rigs all run on brushed motors!!!

i refuse technology!

This is the kind of topics we need here.. Lets not just go straight to CB and ask.. Lets keep a record of helpfull things like this for everyone.

Thanks for all the replies. Will update soon after rebuild.
