Novak Glitch Buster Capacitor
 

should i be using this with my mmm 2200 combo and a fm radio ? ive read that some have fried their esc while using a 2.4 radio. i guess the way something is wired in the 2.4 receiver that it puts to much strain on the BEC.

i dont have a 2.4 radio yet but down the road i might get one.like i said above iam using my fm radio now and wonder if the Novak Glitch Buster Capacitor is something that is needed ?

nope, thats bs. dont bother running one.

Spektrum has a similar product (a capacitor which plugs into your receiver) and if anything I've just found it helps increase servo response by holding the voltage a little better when you have a really powerful digital servo with a less-powerful BEC.

However, most BEC's now a days are getting much stronger, so you shouldn't have a problem.

Here is the copy for our Glitch Buster capacitor:

Now, whether, or not you need one---I haven't a clue.....:wink:

My MMM works fine with both my airtronics and futaba 2.4 radios so I really don't see the need. Kind of sacrilegious using novak junk on CC controls! :rules: :intello:

i found this...

"The main "issue" with 2.4 is that they're sensitive to voltage drops...rather than re-engineer the receiver to fix the situation, those
manufacturers are coming out with capacitors to put in the battery slot
on the receiver to get the receiver through any voltage drops there are.

Here's a link to the Spektrum one...I make my own, and put one in every
vehicle. Had my brand new RC8 conversion go full bore down the street on
its own at 60+ mph and slam into my neighbor's mailbox post. Completely
destroyed the front end before I even got to run it, and had to replace
the post for the neighbor. Was NOT happy. Haven't had any issues since I
put one of these on all of my cars. It's a 10v 4700uF capacitor....you
can get them at Radio Shack.

i had a problem with cut outs due to voltage drops using a CCBEC (not MMM) but that was only with the mamba max or sidewinder running on 4s1p A123. Weird because with 3s Lipo there is no problem, and using 4s1p a123 with the built in bec there was no problem, only when using ccbec...

I even added like a billion farads of capacitance (slight exaggeration :p) and it made zero difference to the frequence or severity of the cut outs.

It won't hurt to use it, but you don't need to be worried about it burning up your Rx either. I've been running a Spektrum system for over a year now (LOTS of hours in the last year) and never burned up an Rx. If you are really worried about it that capacitor is only a few dollars so go ahead and get it if it makes you feel better.

im not worried about the rx, its the esc im worried about.

well it doesnt do anything for the esc, so using it shouldnt alleviate any of your worries

I still feel my heart drop when I think about this. Cheap, fairly small way to guarantee you won't have brownouts/blackouts.

Not really guarantee. I was having blackout problems using a CCBEC and after lengthy email discussion with CC tech supp, nothing was different (tried ferrite rings and rerouting wires basically). I ended up adding over 10,000uF capacitance and it didn't seem to make any difference to my Rx (futaba 3pm) blackouts. Still on stabbing the throttle totally unloaded the voltage would drop enough to reset the Rx. Thing I don't get is that the problem went away using the onboard BEC. It got hot, but had no blackouts. *shrugs*.

If glitching isn't caused by a voltage drop, you can also try winding the throttle cable around a ferrite ring/donut as close to the ESC as possible. Caps will filter noise and shore up the 5/6v rail, but does nothing for noise on the throttle line. The ferrite ring will help with that. Just depends what the source of the glitch is...

There are several types of caps out there. What was the make/model you purchased/used? What was the application as well? And if you swapped out the receiver for a different one, did it still do it?

In a rustler/sidewinder and a crt.5/mamba max. I didn't have any other receivers to try. Well, I had 5, but they are all the same type/model of Rx. They were just advertised as 'Low ESR' by my local electronics store (link).

I ended up sending it in to be looked at/repaired and got it back saying there was no problem with it.
