Castle Mamba 2200kv motor pinion gearquestion.

[BANSHEE 420]

Hello, I bought an 1/16th E Revo with a Castle Mamba 2200kv motor pulled from the full size revo with esc.Its mounted but I need a pinion gear for it and while I'm at it a new spur gear.But since the stock spur gear is a different pitch than the full size motor I need a special pinion gear to get it to fit.Ive seen some 5mm bore pinions with 48-pitch to match the stock spur gear but I am not sure if they will fit properly.Can someone suggest a pinion that will fit my needs?Also a spur gear to match and some tooth suggestions.
I don't plan on racing just some dirt trails and hills just general bashing.I bought some slicks to for an occasional drift session.I saw Kershaw had some of these and i found a few of eBay and the internet but some of the pictures didn't look right to me.Sorry if I got the pitch size wrong but i believe the stock pitch for the mini e revo is 48 while its big brother uses 32? I'm thinking of going steel or something that will last longer than plastic.If you have any suggestions on other parts I should get to withstand the extra power please don't hesitate to recommend them.

Thank You for any help you can give me.

Stock pitch is 48P. I would like to see a picture of a 2200Kv Castle motor and the Mamba Monster ESC in a Merv.
Bear in mind that you wont find batteries which fit in the compartments and are able to feed that combo sufficient.
You can overpower a Merv but you can even exaggerate overpowering.

Kind of when we put a square port 427 Chevy motor in a little Chevy Vega

[BANSHEE 420]

Send me your phone number or email and ill take some pics with my phone.I have 2 3s lipos powering it 3000 mah a piece if I remember correctly.What do you mean by but you can even exaggerate overpowering.

Thanks for the reply

Like killing a fly with a sledgehammer!

Like putting a 500hp big block Chevy on a Vega made for a little 4 cylinder .. 3000 mah batteries are too big too

I don't think 3000mAh 3S batteries are going to fit.
You can post pics over here. No need to mail them.

The amount of power that the MMM/2200 has, is way more than the Merv can handle. I have a combo that is designed for a 1/10 scale car (Castle MMP/4600) and my car has quite some upgraded parts to be able to handle that amount of power.
What you are planning to use is at least twice as much power. You wont be able to get that power to the ground without serious problems. And if you do, you will have a backflip machine.

I just don't want to take the time to find a place, sign up then figure out how to embed the pictures to this post just faster and easier for me.Maybe some day but just not right now.Its bed time anyways.That is why i said if you want pictures now this is the easier and faster way for me. Send me your email or phone number And I can do it tonight but if not you'll have to wait a bit.

[Petertje60]

It's ok. I am just curious how weird it looks.

[DiggerPede]

WOW! Man that setup is huge. The ESC is huge and the motor can is ginormous. I think it's a 1/10 and not a 1/16. It's going to be hard to find batts with the amount of Amperage to feed that system let alone enough Mah to have fun with it. LOL

I saw this on youtube.

I couldn't hold my laugh at work seeing the video
Great job.

[DiggerPede]

That's just crazy!! I was viewing the video and hoping the dude would run the MERV. Just way to much power on tap.

First step is to jam a motor in it that is way too big -> Done
Second to find a place where the ESC fits -> Done.
Wanna drive with a body? -> fail

Now find batteries that will work and a place to store those -> fail

There is this level of overpowered from where you never will be able to get the extra power to the road anymore. With this combo you are way beyond that level.

[james22]

Lol after looking at that video I reckon a stock E-revo would be quicker lol.

If he managed to put the power down it would only flip on its lid all the time anyway lol. Nevermind handling a track hahaha

[BANSHEE 420]

The body fits perfectly.I can fit 2 3s batterys no problem.There is no such thing as to much power. I can always dial down the power to fit my needs.The merv in the video is not mine.Now can someone get back to my original question about the pinion and spur gears?

LOL ridiculous idea

Given that you can hit 80 mph with a 1406 4600kv motor on 4s what are you hoping to achieve ?

Would need to modify the motor mount to fit gearing for any decent speed

With stock sized tires 28/45 gearing on 6s would be 60 mph or so, doubt you would even get there with the weight of the car

What gearing does it currently have ?

The largest 3s packs that will fit the battery slots are 1800 mah, and they wont be able to provide enough amps for decent speeds

If you are running 3000 mah sized packs you are obviously not mounting them in teh stock location

Sell off the 1515 and buy something more suitable

Cheers

[BANSHEE 420]

ridiculous is my middle name,I am just putting a puzzle together with the pieces I have.Just trying to have fun with a build Ive never seen before.The motor is lined up I'm just asking for a pinion gear with a 5mm bore to fit the stock size spur going from 32 to 48 pitch.If no help Ill guess ill just order a couple different ones and trial and error it since no one here has the knowledge.

Should be able to find 5mm 48P pinions if you look around, try RCMonster or Robinson

No idea what size gearing you will be able to run depends how far the motor sits out

You can get smaller spurs than the stock 45, some have run as low as 35 I think

Cheers

decide how many teeth then search RRP20??; 35 teeth would be RRP2035

Hey man don't be like that. crusey & Peterj are helping ya out. I have that motor in a couple of way bigger trucks and it can break parts easily. I'm fairly new to the MERV platform. We have the knowledge not to run somthing like that in a truck that small. Not saying it can't be done, its just way ridiculous ( btw your middle name ). LOL Are you going to have a battery/ batteries that are going to feed this system the Amps it needs?? 125A is bare minimum, 140A recommended, & anything more is even better.

[crusey]

Wont need that many amps in a car this small but motor will still starve with small batteries

Weight will be the killer

Cheers

[50togo]

Hey crusey,I made an adapter for 3 batteries in parallel with a Watts up meter looking for less voltage drop and more speed .helped a little 7.84 vs 7.37 picked up a little mph but not much

[crusey]

Yeah thats what you would expect

Amp draw is split between the packs when in parallel, therefore voltage under load should be little higher

Cheers

Thanks, heres a vid of it running.

[ngnaw]

I use the 2200kv motor and MMM in my 1/8 HPI Vorza! pinion used is 15T and spur is 48T... Why you would want to use this in the MERV is beyond my comprehension! I can barely control it with the 380 motor and Castle SV2.... Ohwell!

[ngnaw]

Thanks, heres a vid of it running.

http://www.youtube.com/watch?v=fo417...hannel&list=UL

Again I don't understand why they would use this platform to do this kind of mod ****! It looks ugly and weird with those wheels...

[reod12x2]

well i would be more conserned about fliping it on the roof all the electronics exposed like that

to funny

[Petertje60]

Dont think we dont wanna help here....

When you put 6S in it, gear it 35/45 and put 4 inch tires on it, you are theoretically close to 90mph. I assume that you want a crazy top speed, because more power to accelerate will only make it flip on its lid.

You will encounter a few problems tho....
The amps the combo wants to draw will cause your Lipos to drop their voltage seriously with the chance of ruining them.
The car is going to be so heavy that it will be very hard to control on higher speeds.
The torque of the 2200 will ruin something in the drive line in no time.

Of course you can tune it down and still say you have a 2200 motor in your Merv. But hey, then you will acknowledge that there IS a thing called "too much power".

[rc driver dude]

I totally understand. I was just showing you guys some vids I found.

That is cool. Thanks for that.

I was addressing the OP, because I think he has the idea that we dont wanna help.
