Arct1k,

You inspired me to do a bit of modding myself.

I kept it a bit simpler tho. I only did a bit of dremeling on the bottom portion of the case. I made a bit of room for my wires that connect to the switch and the Rx plug. Also made a hole in the bottom to clear out any possibility of rubbing.

Then I just covered it with the sticker.

Thank you for your thread.

That's a nice case mod!!!!

Would it be possible just to put 4 little round foam (or whatever them are) things inside the bottom of the case? 1 at each corner to stop the bottom from hitting or will that make the fan sit up more?
Ill try to find what I am talking about and post it up

Some o-rings or grummets should work as well as rubber, plastic or Teflon washers. I got a Monster Max coming and I'm going to look at everything possible to have it running good. I'm not going to use the BEC as I like my Rx pack too much

.

Yeah, might use some o-rings as I have plenty of them. See how it goes

I dont think it would effect the fan at all, but I also dont think it will help...

as you can see in those two pics, the board is supposto sit on top of the tabs on the case bottom...
because of the design, the board does not sit right. I dont think the best answer is cramming more (o-rings/foam/etc.) under the board because the clearance issue still exists. This is why I removed the sponge that castle put in there. and cut the hole for the board to sit flush.

For me...the castle sponge fix didnt really make sense.

Its as if I had shoes that were too small and started getting blisters...and instead of getting different shoes, I put on a second pair of socks. The shoes are still too tight, but now they are even tighter than before. It just didnt add up. I donno, maybe I missed something

(no patrick, I didn't REALLY do it. just tryin to get a laugh.)

would it be possible to build up those 4 corners up with something (glueing some plastic or even hot glue ) so the board would sit up further and not wobble ?? and would the case still fit ??...or is it just as easy to cut out the bottom of the case ...thanks for the help

I felt the case was a tight fit with just the foam pad...

...When I first got the replacement ESC, i removed the sticker and took a look inside. When I went to snap the case back together, the bottom seemed to be a bit warped when doing so. ....It kinda fought me. Id get one side lined up, and the other required some persuasion(more than I was comfortable with being such a small board)
It was then that I decided to do the mod.

Once I dremeled out a hole in the bottom, it didnt seem to require any force to get the case closed. It snapped shut like it was meant to.

*edit* to answer your question....I suppose its possible, but I didnt try. I believe less is more (so to speak) in this case

I just clearanced the bottom of the case so that the plug would not touch it. Then I made some foam "suspension" pieces for the pcb and put it under the larger wire solder points. So far the fan still works, so I guess the plug is stll intact... I need to pull the esc back out and see how the fan wire is doing. I wonder if it has frayed yet, as it sits between the pcb and the case...

thanks guys for the good info here

The MMM(v2) that I have with the most hours on it now (of all MMM's I've had) is the one that the fan connector broke off of on the first day I ran it. I took this one home after it broke, removed the fan & broken off connector and replaced the fan with one that plugs into the RX. This one is holding up great. I'm starting to think the the fan connector getting banged on the case & into the brain board may be what is causing some of the BEC's to fail.

BrianG · 09.22.2008, 02:52 PM

Well, patrick said many V1s suffered from a bad batch of BEC switcher ICs IIRC. But that aside, the jarring of the connector on the case could put hairline cracks in the PCB, and if it's a multi-layer board, the bad traces could be in the middle or back layer and you'd never know it.

Personally, I like adding "spacer foam" to the PCB itself and keep the bottom whole so that mounting isn't affected (reduced surface area). Unless you make a hole in the case, and then glue another piece of plastic on the bottom...

killjoyken · 09.22.2008, 09:15 PM

Funny, my fan plug broke off just trying to pull the fan off. Whatever, I was planning on running it off the the rx anyway.

Instead of modding the case, I made a case mount that solved a couple of problems I had with my V1s. It now has a quick change fan on top using a 25mm Muchmore Racing fan that I've had good luck with on my MMs. Second, it keeps the case from popping apart. And third (just in case), it's a fire shield for my lipos!

(just kidding Patrick!)

I was rushing when I made it and broke my 3mm tap on the last hole, so instead of a nice countersunk screw, it's a dowel pin.
