MMM v3 Pics - one issue remains...
 

Looks great except I think there is still an issue with the fan wiring...

The routing of the fan cable down the side of the board. Mine was pinched enough on assembly/shipping to cut through all of the insulation and have "live" wire rubbing against the board.. :-(

I'll rewire to have the fan on 100% off of the rx - but going to go for no ubec on the v3.

As can be seen you can "just" get a sheet of paper between HS and bullets...

That's enough clearance for me. Sucks about the fan wires, but like you said it's an easy fix.

My v3 fan wire looked very similar. I also noticed that one onf the rasided edges of the bottom case needs to be clearanced a bit as it appears to be trapping the fan wire between inteslf and the board. I put a bit of small heatshrink on the fan wire of my ve and had issues getting it back in the case... I would almost say to run the wire outside of the case and bring it back in where the signal wires exit (that slot needs to be bigger on the case too.) I will try that on my v3 before I run it...

I have decided that my v3 is going in my hyper8 buggy with a 1900kv aveox on 6s lipo. Going to run the new case and just re-route the fan wire. Only mods that I will do. Hope it survives...

James, can you post a picture of the new case? Thanks.

hey chris, is the case any different to save the bec coil?

The bottom case is 6mm deep and the fan plug is 5.25mm - bec coil is 4.5mm

Foam is now placed to support the brains board not on fan connector / coil

Thanks :yes: now all i need is one of the traxxas mounting kits:yes:

Too bad Patrick did'nt fix the fan wires, seems like the easiest of all the problems they had to fix yet no. I really do not understand the logic when they had to make new case molds anyway. Very disappointing. I was going to run the V3's stock out of the box but now it seems we will all have to open them up & take care of protecting pinched fan wires again. This means taking off the sticker, prying open the case which will never stay securely closed again after you open it.

Patrick how long do you think those wires will last racing off-road when they get damaged just by assembling & shipping the unit??? Hope you have a truck load of those fans to send out for free.

Dude.. Easy up a bit... Where it might be a point of contention... it is an easy fix. I, myself, am happy to have a working ESC.. that appears, thus far, to be FAR ore solid than the previous.

Ask and ye shall receive!!! Sorry about the pic quality. The bottom case is taller, just hard to tell in the pic. I will take the v3 I have apart and take some pics with the board in the lower case.

just so i'm clear hear,being a noob to this electric stuff
i have a new v2 that i just updated the firmware and i'm waiting on a new v3 case from castle
the only remaining issue will be the fan wire issue correct ??
will the heatsink/bullet clearance of the v2 still be an issue ??
i'm just wondering if i need to just send the v2 in and start with a complete v3,instead of trying to fix the v2 ...lol
thanks guys for all the help you give on here to us noobs

With the new lower case the pcb sits flat and there must be almost 1mm clearance between the fan plug and the case. So they cured that issue. The fan also has plenty of clearance between it and the top grille area on the case.

nice job for the case but the fan wire seem to have some issue again....:whistle:

Ok, had a good look at the lower case and noticed that there is a small notch near the clearanced area where the fan/switch wires exit the case. I can only assume it is where the fan wires should go to avoid them being pinched between the lower case lip and the pcb.

So I figured out another place to route the wire that will require minimal case mods and will allow the use of some shrink to protect the wire. The wire is usually brought down between the two caps on the negative bullet side. If you add shrink to the wire it is almost impossible to get it to fit there.

If you move the wire over and place it outside the case slightly it will clear the caps and can go down between the case and the negative bullet. I would put some shrink on the wire and make a small notch in the case next to the bullet. Then there is enough of the wire left to plug it into the pcb and shape the wire so that it fits in the notch that is made into the lower case ledge (shown in the pic above)

however...we need to open the case just to deplace the wire an prevent an fan issue???

Finalized pics of the fan wiring... It is a snug fit with the negative terminal but it all fits and the shrink continues down the wire pst the pcb edge to protect it.

I hope this works, I am sick of opening MMM cases. I will say they are easy to open after the 10th time...

I would at least remove the lower case and try to move the fan wire over to fit in the notch I circled a few pics back... That would be my only suggestion for the best performance...

Mine looks ok. It has alot more clearance than the old case.

It's not pinched yet but I'm sure it will be after a few races. :neutral:

thanks!!!!for the reply...now im dreaming of my v3 units(working whitout issue:yes:)

Thanks for the pics. That seems to be the best alternate route for the fan wires.

yeah...now this is getting a bit muddy..
the user is required to open the esc case and place the innards into the new case? under normal circumstances this would void the warranty for almost any product..wth?
and now fan wires are being damaged during assembly/shipment? can you say IPC standards?
this is really getting a bit too much now that the user has to mod it to make it work reliably regardless if they want to or not.
...perplexed...

So is there still a sticker covering the bottom of the case?

New case
 

What's the procedure for getting a new case? I have a brand new V2 that I've updated the firmware on and I'd like to have a V3 case. Don

This is what Bernie Wolfard had to say in response to that very same question.

"Just call or email us with your request. Our email address and phone number are on our website: www.castlecreations.com."

I just emailed and requested a V3 case for my V2, and they responded quickly and said they would send me one out.

I hope this helps.

i just went to there website http://www.castlecreations.com/ and click on the email address at the bottom and requested a v3 case ....be sure to leave your mailing address. The next day they responded by letting me know they were shipping me one out

Did you send the email to info@castlecreations.com ? I sent one 2 days ago and still haven't heard back. Not sure if I sent it to the right email

yes ,thats the one...did you check your junk mail file ??

Just got my 2-v3's (no.5&6) in the mail today. Lets see if they make it to sunday.

i still think the fan plug is a weak idea.(they really need to improve on it ) when i get my replacements i will just run the fan from the aux port on the receiver. the problem with the switching fan idea is that if u bring your truck in after a few laps and the fan is not running , it could be either
1. not over 150deg
2. the fan/wiring is busted and not working..
so most would assume its not over 150deg and keep on driving but if the fan is not working due to damage , then you will just keep driving until smoke comes out . (exactly what happened to one of my esc's) ..and those fans are not very tough at all.

If you are going thru all the trouble to attach the wire to the rec, why not just add the shrink like I did and re-route the wire. The fan plug on the pcb has plenty of clearance with the bottom case now, unless the pcb breaks in half the fan plug will not touch. The fan wire is the only problem I see now. All of mine will be modded like this, and I expect them to work fine.

also, just switch the esc off and on. if the fans spins again on startup then its fine, if not then time to investigate? or just use a pocket temp guage!!

So this is still an issue. Ohh well, honestly as long as the speedo works, I cant complain. For the price, and everything about the MMM. Its worth it (to me)

Nice to see they kept the bullet plugs!
