you definately do not want locked diffs. It will snap your axles and make it turn like a bus.(your inside wheels need to turn rotate slower than the outside in a turn.) The only tires I know of for monster trucks are pro-lines road rages, IMO they suck though. Maybe 17mm adapters and buggy wheels? We can't determine spur/pinion until we know what motor you'll use, what batteries you'll use, and how fast you want to go. Good Luck, and welcome to the forums!

oh , ok thanks. I thought that's what I would need for drifting and hard pack off-road rally driving , No?

if change to differential what weight of fluid should I put in diff ?

Thank you
oh the motor is Feigao 7xl 2382 kv
Looking for mostly power torque speed would be nice in the 40's
Found this AWESOME SPEED/Motor Calculator but it's hard to figure what gear set

Looking for a 5mm shaft pinion , not sure what size tooth pinion though, any suggestions.

Great looking project, I’ll be looking forward to watching it progress. A few Q &A for you??

1. Those front and rear drive lines are long.. How did you do that (It looks like to cut up a bunch of 3905 drivelines and made one long one ??) just and FYI If you ever need custom t – bones made up just PM Jordan.. He’ll hook you up with his guy who did his..

2. I think the 3905 Trans is rated @ 6s Max so at least you know your limitations there are

3. What diffs are you using ??? the stock 3905 ones or will you be installing these ?? http://www.rc-monster.com/proddetail...RO_DIFF&cat=17

4. I'm assuming that you want some large tires for it so here a link to some 23mm hubs. Or use 17 mm like Paralyzed motioned below. http://www.impaktrc.com/advanced_sea...0e44341af7ef3f

5. I have no idea on the type of tire sorry but Ryo-James will know!!! He’s building a killer 5th scale too here is his thread if you wanted to see how he’s doing it?? http://www.rc-monster.com/forum/showthread.php?t=16158

6. Two 3s 5000 lipo’s should work great, but you will need a MMM V3 or a MGM controller / ESC try here: http://www.rc-monster.com/brushlesscontrollers.php

7. lipo’s here: http://www.rc-monster.com/batteries.php or here: https://www.hobbycity.com/hobbycity/...idProduct=6350

8. You’ll need a good strong servo so I’d go with JR 8711 440 oz or the Airtronics @ 423 oz both digital, metal gear ect..

That’s about all I can think of now sorry!.. OOo 7k in the front diffs and 3-5k in the rear is what oil i use in my trucks..

Hope that helps and have a great weekend

Shaun.



P.S.
Welcome to the forum!


Nothing!.. Hahahahaaa..

Welcome to the forum!
You are an Ace
Thank you ! and HUGE Thanks to your Awesome Feedback and the links, that is really great.

1. they are Revo's cut and used 2 to get the length. outer, innner, outer inner outer to trans
Thank you for the name of where to get stronger ones . I saw those in jordans build.
2. the trans is an old emaxx not 3905, but I like the Laydown option of the Xray b808 diff.
3. diffs are stock with spools. should I go back to Diffs? maybe use Ofna Diffs. cant afford the Hotboddies right now, I was laid off my 10yr job a few months ago and finding another job has been tough.
4.5. I'll check that out.
6. Cant afford a new ESC right now, but thank you for your input.
7. my Mamba max can only handle two 2s lipo, but I will look into those as I will Always Progress in this build as money will allow.
8.Servo will be a Airtronics 400oz or a Hitec 5955 that I have

Thank so much again . You are the man !
like to read your builds

6S is too much for that motor - I would pre-order a a 70mm medusa in the sub 1600kv range with a MMM from Mike...

OK, what do I expect with above and with what lipo?


it's battery and motor time

I have read the tutorial but I'm confused what to get ?
Some help please

this Feigao is temporary

How to decide on motor , C amperage and voltage ?

I'm getting a MMM
Want speeds in the 55+ Or 60 but with lots of torque-

how do you figure this stuff ?




Remember this a 8-9 lb 4wd 20" wheelbase car

Sorry I dont know how to import it but there's a thread in brushless titled 'Is there a rule of thumb to work out motor amp draw' or something to that affect. B4maz posted a calc sheet for working out motor and power questions. It might help you, it helped me.

You’re more than welcome we all help out each other whenever we can..

your MM will do great on 4s no worries, you might want to think about adding a fan and doing mods to it later.. Just a thought..

Jordan is you man on the Center diffs too.. here's link to them if you want or watch Ebay they have some XT8 and 808 center on there now of sale
http://www.amainhobbies.com/product_...oducts_id/8633
You will also need some of these..
http://www.amainhobbies.com/product_...oducts_id/8629 or Ebay for a better buy..

Best of luck again should be a fun build..

Bye the way thanks for the compliments..

For 4s I would recommend adding an extra Cap either the Novak HV 2700uf or similar.

You should also get an Ubec and the 5v fan is not a bad idea...

Wow ! What a Great, informative, helpful & generous FORUM ! You guys are really great. Haven't experienced that much guidance before, the links are great. I believe I have found a place I fit in. I think that what these forums should be not the vague or the acronyms or make you search, ya know. It's really nice to have it all there. I look forward to helping in some way here also.

What do you recommend for 6 volt fans ? ?
going to use a Deminsion engineering BEC. I have Castle becs but I am using them in my Crawlers.
Humm , not sure just yet how to fit-add a Cap on the mamba, Castle tech said it will do well because they are so over built.
I'm stealing the MM out of my Latest Creation Full Throttle custom Super Crawler, build thread just added to my sig, it's got 6 watt 4 speaker MP3 stereo loaded in it complete with Real V8 engine sound.
Here's a sneak peek




My latest creation below
Console shifter turns car on
twin stick turns on stereo Amplifier
Sony MP3 with Tunes and Real V8 engine sound
18" wheel base 14" wide
Axial trans
Revo drive shafts
Losi aftershock Diffs, custom lockers
Hyper 8 shafts
Xtm hubs
custom SS axle tubes and Knuckles
1/4 Tube steel MIG welded Chassis
2wd, 4wd and DIG by Remote
HiTec 7955 front rear steering servos
Castle bec
Mamba max
Climbs great when tires are working, Moabs stink

dude! i love that crawler. thats what i want to build soon. i will hit you up with many questions when i do i am sure. it looks great. here is my most recent build. http://www.maximizerproducts.com/max...mm_Hex_C35.cfm

as for 1/5 scale wheels and tires check here.
http://www.oversizerc.com/c/167427/1...and-tyres.html
http://www.hm-modellbau.de/shop/

its in german but you can usually tell what it is saying by deciphering from the pics. or you can translate using this site.
http://www.freetranslation.com/

and for more 1/5 build info contact Mohanjude here on the forum. he has built more 1/5 stuff than anyone i know and has lots of resources as he lives in europe where 1/5 is more dominant.

Hey guys, thanks again on info
I have been grabbing things to sell and put on ebay so I'm buying some 5s Lipos and a MMM
Spoke to Castle, recommended the 2200 motor and 4s for 45mph and 5s for 50+mph

going with Losi aftershock diffs with my own lock/spool, may use gorilla snwatt in front diff

putting in some Losi 2.0 truggy or 8ight front Shocks
and some integy Upper revo arms
also going to find a way to mount some 1/5 wheels

It's getting Exciting

The castle 2200 motor on 5s lipo runs great in my friend's savage. Plenty of power. He runs a 4900 mah 25c 5s lipo, and it does fine. He is currently geared for about 42mph, but we had it geared for 55 and it did fine for a 5-8min run (had to stop as we were going to break stuff at that speed!).
