keep us updated lol i will need all i can get! lol

and thanks for insipreing me to convert a buggy!! and spend 2k on a rc car lol its worth it tho, especially when u can make a few parts for it that u cant buy off the shelf

This is only one of many buggies I've seen here. Do a little searching and you'll find a LOT of very nice setups.

The only trouble with fabbing your own parts is that if one breaks, you can't simply run into your LHS and get a replacement; you have to build it over again. This of course effectively kills a race day!

part numbers for the 777 diff?? please??? lol

and those will work no mods? then i can use the right stuff, correct???

BrianG · 01.31.2007, 08:32 PM

Sorry, I don't know the part numbers. I'd probably just pick up the whole diff from ebay or something like that - it'll be easier and cheaper than building it from parts.

Anyway, I'm bummed. :dft004: Turns out the Quark simply won't fit. I can get it where I want, but the edge of the ESC is too close (~1/8") to the lipo batteries for my liking. If I move it so it has enough space, it sits too close to the body and may contact it if/when I crash and it lands on its lid. :007: The 80B would fit much better, but the current isn't high enough IMO. So, I had to get a MM as much as I didn't really want to. Oh well, at least I'll have an ESC for my next project.

that STNKS!!! lol didnt someone say ohh y did u get the quark when u could of had the mm for 140$$ less????? lol

That was MetalMan! :p Sorry to hear that Brian..

BrianG · 01.31.2007, 08:48 PM

Yeah, I know, but I wanted to use the Quark. I'm only using the MM because I have no other choice. I have a mind to get it to work despite the fitment issues just to prove a point now. :p

Im running the 80B in my buggy with no problems. The 80B is good for 200 amps for 10 seconds. Do you really see excerding that? Even in my Monster Trucks I dont see spikes that high. Certanly not for 10 seconds. I have a custom heat sink I made up for it to help keep it cool. Just my $0.02.

lol ohh well its only money right?? :D

Well thats what these conversions are about, you have to use your head to find a way to make things work, and if they dont, you comprimise. Are you sure there isnt any possible way of mounting it or not?

glassdoctor · 01.31.2007, 11:27 PM

I don't see a problem having the controller next to the battery.

Are you concerned about heat from the battery? The battery likely will never get over 120* even on a 90* day... that's the hottest I have ever had a lipo get. My lipos generally don't get much above ambient temps (in summer)... maybe 10-20 deg.

I need to go back and check the layout you are using... I forget exactly what it is.

Just build a mount for esc, use standoffs and you can raise it over anything.

BrianG · 02.01.2007, 01:24 AM

OK, without pics, this is hard to explain, but I can get it mounted. I just don't like the edges of the ESC so close to the battery (it's not the heat aspect). Call it being anal. :) If I raise it with standoffs or whatever, it interferes with mounting the shell. Plus, I want to leave a little room between the shell and the parts so that if I land on the lid, it won't bend/break anything. I know the real answer to that is to drive better :). Part of the problem here to is that I want this thing to look like it was designed for BL, not converted. So, no shortcuts or hackjobs. Another part of the problem is that I'm using Lipos in this and am a little gun-shy. You should see me handle them; it's like I'm carrying a bomb. I actually thought about making a metal enclosure for them! Yes, I'm paranoid. :)

A little earlier, I re-made the battery tray standoffs so they are now 1/8" further back. This should give me more room no matter which ESC I end up using for this. At any rate, the MM is on the way, so I'll have options. I have another conversion planned after this is done anyway...

Regardless of these "roadblocks", I still love these conversions. A little frustrating at times, but the end result is always worth it. Although, you wouldn't think I like doing this if you heard me downstairs swearing when something goes wrong. :)

I know what you mean about the lipo's being paranoid. I will be too, once I buy them, lol. But it is all part of it. :027:

glassdoctor · 02.01.2007, 02:04 AM

Yeah... I keep my lipos buried in my underground bunker in the backyard... ok... not really. But I do have them in the garage. :)

I treated mine like nitroglycerine too... mine have all been bare cells... no prebuilt packs. Desk looks like I'm doing surgery when it's time to solder them up, lol...

Well, not so much anymore but still...
