Project Super-VBS-CF-Gorillamaxx!!!

[jordan...]

Yep, i just got a MMM V3 last week. Im running 5s, same as in the vid, im not THAT crazy . My MGM is limited upto 6s anyway. No worries on the ratio, ill work it out now, just didn't know which diffs you were running (RCM buggy or truggy ) Gotta remember the gmaxx single speed ratio is 1.7777, but with the CD its 1:1, i've also got buggy ratio diffs, so the spur/pinion will be kinda weird. No need for the gears, i don't think they'd fit between the frame rails, ive got a 48/10 combo to try out. I'll crunch some numbers right now, but i think theres something wrong with Brians calc, theres a Neu 1515/3D, but no Neu 1515/3D (polished) option .

The necks real good now, im back to running, riding, gyming again. I just got cleared to get back into all this stuff a week ago, also back at work which is good, i need more money for RC Unfortunately i cant get back into a race car for another 3 months, need to wait for the muscles/nerves to regenerate, (they take alot longer than bone.) So hopefully by March everything is all good.

have a good sleep

EDIT: thanks to BrianG's calc, heres what i got...

Shauns final drive ratio: 16.04537:1

My 42/16 final drive ratio: 8.68269:1

My 48/10 final drive ratio: 15.87692:1

My 46/12 final drive ratio: 12.67949:1

Now i know why my MGM burnt...

Time for some updates i think!!!

I got my gears from Amain, ordered Tuesday, arrived Friday, cant get much better than that!! So i went about modding my CD mount and my frame rails to fit with the larger 48t spur gear. I cut a slot into the bottom diff plate for clearence, and also notched out the frame rails. I also went about direct soldering my motor to the MMM wires. I had to make some small extensions to get them to reach. I think the MMM install went great and im happy with how clean it looks. Here are some pics...

Down for maintanence



slotted and notched parts



wire extensions and motor with wires directly soldered





Some pics ready to run!!









Read on to see the truck with the MMM ran...

... so i took it out for a run this evening.

WOW is all i can say With the lower gearing this thing came alive. Still no wheelies, but SO much power, and all of it useable. Handled awesome as before. Mostly kept all four wheels planted round quick corners and pulled some nice 4 wheel drifts. The MMM ran excellent!!! It was really smooth on startup, no cogging at all, the brakes were perfect and it really delivered the power smoothly through the whole throttle curve. So happy with its performance, my temps after about 15-20mins were

motor 110-120F
ESC 120-130F
batts 80-90F

The fan only came a couple of times, but after i let the truck sit for around 10 seconds it went off and was ready to go again. I'd like to say that the MMM really can handle any motor thrown at it, great job Castle!!!

Heres a vid:



Now for the aftermath, can you spot whats wrong with this pic



The pillowballs screwed out, which made the driveshaft pop out of the cup, and under some hard breaking, sheared the pin









My question is, is there an easy fix for this problem? Can i get the pin out somehow, i was thinking about drilling it out, and then put a drill bit or allen key in. Much like the roll pin mod people do in the 3906 tranny's. Any suggestions, i cant wait to run this thing again!!!

hope you liked the updates

The pins are surely put in with a hydraulic press, so you should be able to press it out if you have access to a press. Then press a new pin back in. Yes a drill bit or allen key should hold up just fine. Nice work on the vehicle, and it looks to run pretty well with the MMM. How much does that thing weigh loaded up? It looks to be kind of heavy in the Video. Just curious. Looks like you have a new bouncing baby boy on your hands. Way to go Jordan.

i have got a mate whos a mechanic, so i should have easy access to a hydraulic press. It is a bit of a beast, 14lbs all loaded up. It sure did run well with the MMM V3, time will be the test now i guess, hopefully it doesn't crap out on me after a couple of weeks.

Well considering what you have in there, that is not too bad for weight. Half of that is probably batteries, and motor. All you can hope for is that it holds up until your MGM is returned from the factory. I would have some fun, but nurse it a little bit until you get close to having the MGM back, then run the hell out of the MMM. Then you will have a good comparison going between the two. You can also order those driveshaft pins either from UE, or RCAlloys. I am not sure if Mike has them or not here on RCM. It would not hurt to have a few spares on hand for future issues.
