Project Super-VBS-CF-Gorillamaxx!!!

Not sure what solder exactly, i just bought it from the electronics place. Its 99.3% tin and .7% copper if that helps . Good to know about the mgm, i'll make sure to do that. With the gearing, i had no idea where to start because AFAIK there are no others trucks with the same ratios as this, so i just picked 16t, i didnt think id be THAT far off the mark

I think i might try fit a 50t spur on, to get this gearing thing sorted, i might have to notch the frame rails though. I'm still not sure... I could mod my motor mount to accept a 14t pinion, but i dunno if that will be a big enough drop.

It's called a learning curve RVO. Anyway Jordan that lose connection probably caused most of your overheating problems, but you still want to start out easy with the gearing up front to see how it handles first. Then as you see the data (IE: temps, speed, & operation) you can gear up until you reach a happy medium. I do hope that you did not do any damage to the ESC.

Just clean out that plug and resolder it correctly and you should be fine with that. I would look real closely at the other connections as well. Then work on getting your gearing correct according the the recommendations from Lutach.

You can do this:
(You have a 42t spur right??)
http://scriptasylum.com/rc_speed/_gear_calc.html
Using the bottom calc with 42/16 gearing it says 31mm shaft spacing. Without changing your motor mount, you can gear 48/10 with 31mm spacing, leaving your motor mount the same, bringing you to a easier 50mph... (probably closer to 45 when all factors are considered)
Here is a 10t pinion and some 48t spurs, not sure which config you need:

That is genius!!! I would've never thought of that. Thanks BL_RVO, i'll get right to it I might also try out 46/12

Hey Jordan the center diff in my G3R is a 48t Kyosho item. it fits perfectly.

No problem, always willing to help. 46/12 is too high...

hmm.. ok, ill grab one of them, what pinion size are you using? Oh, and do you have any pics of your setup? Would like to see how your CD setup is layed out.

46/12 is too high...

I hope you're joking and another thing, when taking the heatsinks off of the MGM, is there some kind of paste under them that i would have to put back on when i re-attach the heatsinks? It looks as if there is some kind of glue or something under there, im assuming it just helps with the heat transfer?

[JERRY2KONE]

Yes Jordan it is thermal paste used in most PC applications for putting a heatsink on the processor. You can get it at most PC stores, or order it on line at TigerDirect.com.

Sorry Jerry, i didn't see this post earlier great advice. I'm going to go with the recommendations of Lutach an BL_RVO and gear it for around 50mph. I don't think i did any damage to the controller, all the components look ok, i did stop straight away when i saw it at 180F

[SV6000]

Hey Jordan there is a picture here is a picture of my setup, i got i second hand off a guy on the traxxas forum, but it is the same as i have now. The only difference is that i am running a NEU 1515 1Y/F instead of the Lehner and i mounted my speedy on top of everything with an aluminium plate, sort of like what you did. I will post photos of my exact setup next week when i get back from work http://monster.traxxas.com/showthread.php?t=434613

[jordan...]

Are you serious I only saw the black and blue E-revo that guy made, not the G3R, thats freakin awesome. Can't wait to see some pics. Do you work up north at the mines or something?

BTW, i e-mailed Martin at MGM about replacing the heatshrink, how long does he normally take to reply?

[SV6000]

Yeah i work up north on the mines but i only do one week at a time. Martin is really quick to respond or someone else will, i got a response on sunday and monday just gone for an issue i was having with the BB-O3. By the way i was waiting to see how your motor was going to perform, i was thinking about getting one. I have a CF and AL version of the G3R. I could extend the AL version and put a 1527 in that. SO LET ME KNOW WHEN THE THING IS SORTED and i will meet with you to see how it goes first hand. I will be back in town next wednesday hopefully we will be able to meet up than.

[jordan...]

I just got a reply from Martin, awesome service, he said if i send it back to get it fixed up i wont void my warrenty and it should only take 2 days to fix. So i might do that tomorrow. I'm putting my order in for the gears tonight, so they should be here within 5 days. Im not sure if ill have the MGM back by next week, but i will have an MMM V3, so i might try that out. Hopefully it will be sorted ASAP, looking forward to running with your G3R. BTW, what do you do up there, ive got a couple of mates who are diesel mechanics, one's in Port Headland and the other is a couple hundred kms out of Karratha, i bet its fun on those 45*C+ days .

[SV6000]

Diesel mechanic, yeah 45*C+ days are great especially when you have to wear long pants and shirts. but it beats being burnt by trubos and other things of the like

[SV6000]

Mate i would do the math on the V3. It is only rated for 120A, and considering your motor will pull 200+ amps on 6s i would hate to see you sending two speedies off for repair in the same week. Yeah hopefully you will get your speedy back from MGM soon. Not to rain on your parade but when i ordered mine from them it took 3 weeks to get to me. so your probably looking at about 8 week turn around
