Possible Goat \ BL Issues

[prophetz]

My rig starting acting funny the other night. I’m crawling having a good time then all of a sudden I hear a pop and my rig jerks. I was thinking great, stripped the teeth off of something.I got home took the rig apart and every gear was fine. Along with the MIP drive shafts and out drives. Put it all back together and tested it in my basement, and it started doing it again! The only thing left that it could be is either the ESC, Brushless 18.5 or a combo of both. Has anyone heard of this before? I’m going to move my electronics around tonight and see if it makes a difference. It happens randomly, doesn’t have to be under a load, but it seems to do it more often when it is under a load. Any ideas?

Just a random pop would be pretty hard to guess on. Maybe a loose plug, and there's a bit of arcing going on??

Sorry, when I say pop I ment gear pop not electrical. Im going to tear everything down again this weekend. It has to be something I have missed!

I have 4 of the Goat systems and I have problems with them all. I haven't heard any pop but the truck will leap forward when I touch reverse randomly. I have checked around a bit and everyone says it is my batteries (doesn't seem right to me). I could use some advice here as well. Right now Novak is not in my good books. I have sent 3 of them back for service in less than a year.

uhm, uhm, NOVAK, uhm, uhm.

















ya i got a goat to, my favorite "goat glitch" is the one where you turn the truck on and it takes off full throttle. then you try 4 times to reprogram it before it rips out of your hands. soon to be replaced with a cc mm pro.

This is the response I got back from Novak!
"It sounds as if the magnet may have come loose from the rotor shaft. If you have a spare rotor from another Novak brushless motor, I would recommend switching the rotor out and trying it again. That could really be the only thing you are describing besides a slipping gear or driveshaft."

I took the motor apart, everything looked OK. But what do I know. The rotor looks like any other brushless rotor. Think I am just going to get a 35T or a 45T brushed motor and be done with it! Knowing my luck its probibly the damn ESC!

If your system is under warranty, you should return it for service or replacement.

I am sure it is not. I have had it for 4 or 5 months and I know I no longer have the receipt. Guess I could pick up a new rotor and see. If I do I just hope it solves the issue!

I have the same setup,and had this problem for a while now,i could never put my finger on it! I was just going to wait till something broke, but it will not! Just keeps going.

I have just about replaced everything that I could. I just got my Fasst module and receivers about 10 min ago in the mail. That will remove the TX and RX from the equation! I'm going to install a stock brushed motor tonight, if it still does it the ESC will be next. If it does it after that I have about 750 rounds a 9MM +P+'s I can use it for target practice!

Have the same problem with my goat 3S dont remember any issues like this with the goat 2s. Maybe will try it again. You try to ease into reverse and the truck jerks a bit. Not every time but still annoying. I do run a castle bec so the red is pulled out the plug at the reciever. I thought maybe it was getting feedback on the black wire so I pulled it as well. Well that made it 20 times worse. You could not even drive more than a couple feet without it doing the funky chicken. First time it did that I thought it munched my gears it sounded so bad. Going to swap recievers and see if there is any change maybe run a different radio as well. :?

i've only had the jump back and forth glitch once since i went 2.4, unplugging the battery and plugging back in was the fix. and ya i does yank hard enough to make you think somethings gonna break, deff pops the gears. also maxing the deadband on the ESC helps. IMO novak crawler stuff is just fancy packaging to catch a newbie, that thinks "it says crawler so it must be what i need.".


Here's a thought NOVAK, instead of paying someone to post a standardized "please contact customer support" and never offer any real help. PAY SOMEONE TO TEST AND UPGRADE YOUR PRODUCTS, LEARN WHAT DRAG BRAKE IS, AND FORGET 2S. in this day and age you should be releasing 4s stuff, CATCH UP.

lol never had such a good laugh.. good stuff

[prophetz]

Well I think the funky chicken (<-- That is what it shal be refered to from now on) Is gone! Here is what I done tonight.

Installed Futaba 2.4 Fasst receiver "Was running FM"
disassembled motor and blew it out with canned air.
Rerouted the power wires away from the control and sensor wires as best I could.
Made shure that my pinion and spur mesh was not to tight!

Ran about half a pack through it and nada, nothing zilch!
If I was running crap electronics I would feel safe blaming the receiver, but I have tried 4 fm receivers. My feeling is it had to do with the wires. Just like a car radio, keep your power and your signal wires away from each other. Im running a SWX chassis so that can be a little hard to do. Give one of these a try if not all of them and see if it helps. This is my first 2.4 setup and it rocks! I hope so I was about to pull whats left of my hair out!
Good luck.

To all,

Generally it is best to email us at tech@teamnovak.com with your problems along with the information on your equipment that Novak2 mentioned.

Electronics are getting to be a complicated affair and the interplay between different components cannot be overlooked!

It is much easier to deal with customers on a one-on-one basis via email instead of trying to pick and sort through posts on forums trying to excavate the necessary information to help fix the problem.

Just glancing over some of these posts below I would be very interested to find out what kind of radio systems are in use in each of these vehicles and how well the wiring is routed ... and to ensure that before the vehicle is turned on, that the transmitter is powered up.

I was running a Futaba 3PKs FM with a futaba, Novak Synth, and a airtronics receiver. Now I am on a 2.4 Fasst system using the 3PKs.

I try to keep all my power wires away from the signal wires as best I can.
Being in the RC hobby for some 30 years, I can assure you that my TX is on well before the RX is on or the battery is hooked up for that manner!

prophetz,

It sounds like you may have solved your problem. We have always said in our instructions that routing power wires and signal wires together are a real no no. I learned this leson early on when I first started flying RC airplanes over 50 years ago. I know that a correct instalation in a crawler can be difficult at times. What I would like for you to do is try your old receiver and see if the problem comes back. If it doesn't you have solved your problem.

when i had the most problems i had a futuba AM unit that i've had 15 years. wiring was seperated and i moved the different peices everywhere on the truck. at one point i had the ESC on the back, rx mounted off to the side of the truck, power wires all on right side and no rx wires anywhere near each other until they all meet at the rx. (servo went to front and esc to rear, at least 3 inches from any power wire.

now i run a KO PROPO EX-5UR, CC BEC, JR8711 and futuba S9650, i've had the back and forth glitch once since the new radio and the take off at full throttle once with the new radio. also at the last comp i was upside down in loose gravel and the motor would stop and start at random times at full throttle while trying to get it back over.

the full throttle deal is the one that baffles me cause when you finally get it to go into setup without ripping out of your hands it fixes it, that tells me it's a problem with the ESC not radio or wiring.

my biggest gripe with the unit is the weak drag brake, the hold brake is nice but when you give any throttle downhill and the rig takes off it bites, nothing you can really do to slow the rig down either cause if you let out it'll flip. the hold brake is supposed to be progressive and stop that, but at any setting that holds the truck decent it locks up way to fast.

Im going to do that tonight! Thought about it last night but it was to late! I will post back my results!
